While senior management has primary responsibility for managing risk on a day-to-day basis, our Board is responsible for overseeingour risk management processes. These processes are a coordinated effort among our business units, senior leadership, riskmanagement personnel and internal auditors. Directors typically monitor our risk profile by receiving from management periodic briefingand educational presentations. The Board works with senior management to assess our key short- and long-term business risks,including an enterprise risk management reporting process designed to identify critical risks and formulate risk mitigation strategies.Half-yearly, the Risk Management team briefs the Board’s Risk and Security Committee on issue that include risks to companyproperty, assets, and operations from climate-change related issues such as flooding, hurricanes, wildfires, wind-storms and othersevere weather phenomena.

(C1.2a) Describe where in the organizational structure this/these position(s) and/or committees lie, what their associatedresponsibilities are, and how climate-related issues are monitored (do not include the names of individuals).

The Environmental Sustainability Committee is a multi-disciplinary team comprised of Directors and Managers from the functionalgroups that are tasked with managing the company’s significant environmental impacts. Committee members are directly responsiblefor company operations that contribute to our carbon emissions as well as other environmental issues such as regulatory complianceand waste management. The environmental sustainability committee is responsible to identify and assess the impact of thecompany’s operations on the environment and to develop and implement strategies to mitigate those impacts. The committee alsoestablishes targets pursuant to our ISO 14001 certified Environmental Management Systems (EMS's) (where relevant) and partnerswith other stakeholders to meet environmental sustainability objectives that support company objectives. The rationale for staffing andassigning this committee with the aforementioned responsibilities is to engage with the leaders and Subject Matter Experts (SME's) ofthe work groups who can most directly improve our environmental performance.

The committee members have the responsibility and authority through their assigned job duties to implement processes that drivecontinuous improvement in environmental performance including greenhouse gas emissions reductions. The committee is led by thecompany’s Director, Global Environment Health & Safety (EH&S). This position resides within the Finance/Treasury/RiskManagement organization and is responsible to lead the global EH&S function including establishing, monitoring and managingoverall EH&S objectives, performance and regulatory compliance. The Director EH&S reports to an officer of the company (SeniorVice President - Treasurer) who in turn is a direct report of the Chief Financial Officer (CFO). The Director EH&S coordinates withregional EH&S leaders in EMEA and LatAm in order to create and implement a global vision for environmental sustainability atCenturyLink. The committee effectively monitors climate change issues through regular meetings internally as well as engagementwith professional organizations and regulatory agencies, and through subscriptions to services that monitor energy and environmentalrelated initiatives and rule-making that may impact our industry. This structure utilizes the organizational hierarchy and reportingchannels to link top level oversight to those with high level responsibility for operations that influence our management of climate-change related issues.

The Treasurer leads the treasury, risk management, and environment health and safety functions. As regards climate change relatedissues, the Treasurer is responsible for approving certain environmental sustainability targets and objectives and ensuring adequateprocesses and systems for evaluating and effectively managing and monitoring regulatory and financial risks related to certain climatechange related impacts to the company’s operations and assets.

The CFO leads the Finance organization and is responsible for supporting company-wide objectives from a finance perspective. TheCFO is also the executive responsible for the overall performance of the finance function, which at CenturyLink includes theTreasury/EHS/Risk Management team described above where assessment and monitoring of climate related issues occurs. The CFOreports to the Chief Operating Officer.

(C2.2b) Provide further details on your organization’s process(es) for identifying and assessing climate-related risks.

CenturyLink’s processes for identifying and assessing climate related risks are integrated into a multi-disciplinary company-wide riskidentification, assessment, and management process. Risks are identified and assessed on a minimum 6-monthly cycle (or morefrequently), and in relation to a time horizon which extends beyond six years. CenturyLink estimates that a $25M unanticipatedexpense from climate-related risk (e.g. property damage due to floods or hurricanes) would have a substantive financial impact due topotentially adverse impacts on our property insurance program. Substantive financial impact is not meant in this context to imply animpact that would adversely affect the company’s ability to meet its overall financial objectives.

Climate-related risks are identified and assessed by various teams using a variety of risk management processes in place atCenturyLink:

Enterprise Risk Management (ERM) Risk Assessment – This is an annual cross-functional process used to identify the key risksto the organization. The ERM team interviews designated company leaders as to the material risks to the organization. If climate-change related risks are deemed material they would be identified, assessed, and prioritized for action through this process. Risksare ranked using both quantitative and qualitative methods, incorporating perceived impact, likelihood, and the level of managementor control over that risk. The results of the risk assessment are provided annually to the Risk- Security Committee of the Board ofDirectors.

Environmental Sustainability Committee – This multi-disciplinary team meets monthly and is comprised of Directors and Managersfrom the functional groups that are tasked with managing the company’s significant environmental impacts. The environmentalsustainability committee is responsible to identify and assess the impact of the company’s operations on the environment and todevelop and implement strategies to mitigate those impacts. In conjunction with the Environment Health & Safety team thiscommittee also evaluates current or emerging regulations and industry trends to help identify and assess climate-change relatedregulatory, reputational, and market risks to the company. These teams engage with policy makers, EH&S professionalorganizations, industry groups, and internal regulatory affairs experts to identify, assess, and plan for relevant climate-change relatedrisks.

Business Continuity Planning Team – This team develops, implements, and maintains our business continuity risk managementframework. This framework requires each functional group to evaluate the criticality of their business processes at the location orasset level. Critical processes are subject to a Business Impact Analysis which includes criteria for materiality and priorities.Maximum allowable downtimes are identified which drive the recovery time objectives for critical processes and systems. Thehazards/threats that are possible outcomes of climate change that are included in this process include flooding from rising oceanlevels or increased severe weather, disruption to our supply chain, loss of people or facilities due to disruptive natural phenomenasuch as tornadoes, cyclones, tsunamis, hurricanes, drought, wildfires and other extreme weather events as well as displacement ofpopulations and civil unrest. The overall business continuity strategy, processes, and results are communicated to the executiveleadership team and made available to all employees.

CDP Page of 1037

(C2.2c) Which of the following risk types are considered in your organization's climate-related risk assessments?

Relevance&inclusion

Please explain

Currentregulation

Relevant,alwaysincluded

Current regulations are relevant and always included in the company’s processes for identifying and assessing climate-related risksbecause (1) telecommunications is a highly regulated industry and (2) our operational footprint includes many countries with differentregulatory requirements, and the consequences for non-compliance could negatively impact our operations, financial performance, andreputation. An example of a current regulation related to climate change risk that the company has identified, assessed and is currentlymanaging is the Renewable Energy Standard (RES) in Colorado US. This law/regulation requires investor-owned utilities to generate30% of their electricity from renewable sources by 2020. This regulation and its revisions have the potential to increase energy costs forthe company’s operations in Colorado. Through careful monitoring of the state regulatory environment we were able to identify thepotential risks and opportunities from this regulation and take action to mitigate the risk. For example, facility energy efficiency projects(equipment optimization, upgrading building control systems, lighting replacement initiatives) were implemented to mitigate the risk ofincreased energy costs that may arise from this regulation.

Emergingregulation


Emerging regulations are relevant and always included in the company’s processes for identifying and assessing climate-related risksdue to the potentially significant impact on the company’s ability to meet its objectives that may occur due to the cost of compliance withemerging regulations or the adverse consequences of non-compliance. As example of an emerging regulation related to climate changerisk that the company has identified, assessed and is currently managing is the increasing use of carbon emissions cap and trade orcarbon tax systems. These schemes currently impact a small percentage of our operational foot-print but the impact may increase ifthese schemes expand into the telecommunications industry in the US and/or into other geographies with a higher percentage of thecompany’s carbon emissions. The company has responded to the potential for this emerging issue to impact our energy spend byimplementing energy efficiency projects to reduce consumption and by expanding our procurement of energy from renewable sources.

Technology Relevant,alwaysincluded

Technology is relevant and always included in the company’s processes for identifying and assessing climate related risks due to thepotential negative impacts of not optimizing energy efficiency at facilities. An example of a technology risk related to climate change thatthe company identified and assessed was the potential for increased capital costs as a result of insufficient payback from the installationof Alerton HVAC automation systems at several facilities. The company evaluated the risk and determined that despite significant upfrontcosts, the investment would benefit the company financially on a long-term basis in addition to increasing energy efficiency and reducingcarbon emissions.

Legal Relevant,alwaysincluded

Litigation and claims are relevant and always included in the company’s processes for identifying and assessing climate-related risks dueto the potential negative impact to our financial objectives and reputation that may arise from such litigation and claims. An example of alegal/claims risk related to climate change that the company has identified, assessed and is currently managing are general liabilityinsurance claims in the US that may arise from severe weather dislodging or damaging our aerial telecommunications plant in a mannerthat creates a potential hazard to the public as well as the increasing risk of wildfires in the western US that may involve or be attributedto our outside plant equipment and utility poles that we own or have installed equipment.

Market Relevant,alwaysincluded

Shifts in supply and demand are relevant and always included in the company’s processes for identifying and assessing climate relatedrisks due to the potential impact of decreased revenues that could arise from not capitalizing on new market opportunities. CenturyLinkalways considers ways to help customers reduce energy consumption. For example, CenturyLink capitalized on increasing demand forvirtualization of entertainment by partnering with Netflix in order to deliver customers fast and reliable entertainment services.

Reputation Relevant,alwaysincluded

Reputation is relevant and always included in CenturyLink’s processes for identifying and assessing climate related risks due to thepotential negative impact of lost revenue that may arise from customers dissatisfaction with CenturyLink’s lack of participation in variousenvironmental disclosure platforms. CenturyLink discloses climate change and sustainability information to its employees, customers,and investors to protect and enhance our reputation as a good corporate citizen. For example, our response to the CDP climate changeand supply chain questionnaires helps ensure transparency and communicate our performance and practices to customers.

Acutephysical


Acute physical impacts of natural disasters and extreme weather are relevant and always included in CenturyLink’ processes foridentifying and assessing climate related risks due to the potential negative impact of lost revenue and increased expenses that couldarise from damaged infrastructure. For example, a building in York, UK was determined to be at high risk of flood damage. The buildingwas vacated and assets migrated to another location, in order to reduce flood risk and ensure operations could be more reliablymaintained.

Chronicphysical


Chronic physical impacts of natural disasters and extreme weather are relevant and always included in CenturyLink’s processes foridentifying and assessing climate related risks because network outages due to extreme weather could result in lost revenue andincreased expenses. An example of an identified chronic physical risk that could impact the company is rising sea levels

Upstream Relevant,sometimesincluded

Upstream risks are relevant to the extent that suppliers of energy are considered, for example with regard to the cost of carbon taxes andthe cost of carbon trading e.g. EU ETS. We, in part, manage such risks by procuring renewable energy.

Downstream Relevant,alwaysincluded

Downstream risks are relevant and always included in CenturyLink’s processes for identifying and assessing climate related risks due tothe potential negative impact of reduced revenue from unsatisfied customers. For example, requests from customers/investors toincrease disclosure of greenhouse gas emissions and sustainability efforts are increasing. Not responding to these requests couldimpact demand for our products and services

(C2.2d) Describe your process(es) for managing climate-related risks and opportunities.

Environmental Sustainability Committee – This multi-disciplinary team meets monthly and is comprised of Directors and Managersfrom the functional groups that are tasked with managing the company’s significant environmental impacts. The environmentalsustainability committee is responsible to identify and assess the impact of the company’s operations on the environment and todevelop and manage strategies to mitigate those impacts. In conjunction with the Environment Health & Safety team this committeealso evaluates current or emerging regulations and industry trends to help identify and assess climate-change related regulatory,reputational, and market risks to the company. These teams engage with policy makers, EH&S professional organizations, industrygroups, and internal regulatory affairs experts to identify, assess, and manage relevant climate-change related risks.

Business Continuity Planning Team – This team develops, implements, and maintains our business continuity risk managementframework. This framework requires each functional group to evaluate the criticality of their business processes at the location orasset level. Critical processes are subject to a Business Impact Analysis which includes criteria for materiality and priorities.Maximum allowable downtimes are identified which drive the recovery time objectives for critical processes and systems. Businesscontinuity plans are created and exercised by Plan participants to ensure effective management of identified hazards/threats. Thehazards/threats that are possible outcomes of climate change included in this process include flooding from rising ocean levels orincreased severe weather, disruption to our supply chain, loss of people or facilities due to disruptive natural phenomena such astornadoes, cyclones, tsunamis, hurricanes, drought, wildfires and other extreme weather events as well as displacement ofpopulations and civil unrest. The overall business continuity strategy, processes, and results are communicated to the executiveleadership team and made available to all employees.

Identified risks and opportunities are prioritized based upon the immediacy and potential severity of the disruption to the company'soperations. Risks related to impacts of global climate change for example are prioritized based upon disruption of network servicesthat may occur due to physical damage to our network from flooding or severe weather events. Opportunities are generally prioritizedbased upon a return on investment formula which is informed by the current business environment and financial performance.

An example of a case study that demonstrates how our risk management process has been applied to a physical risk is hurricanepreparedness. The BCP team provides the framework and readiness criteria that is expected from potentially impacteddivisions/locations in the event of a hurricane event. The focus of hurricane preparedness efforts is prevention and mitigation.Applicable divisions/teams/individuals are instructed and expected to review checklists and training documents, in addition to site-specific business continuity plans, continually to ensure they are prepared at all times. CenturyLink’s hurricane preparedness effortsnot only show how the company mitigates physical risks due to extreme weather, but also demonstrates how the company capitalizeson the opportunity to improve our customer experience through dependable network/connectivity services during severe weatherevents.

An example of the process as applied to transitional risk is evident in our shift (in European countries) to renewable energy use inorder to reduce the impact of carbon taxes e.g. Germany, Italy, Spain. In addition, Critical infrastructure Teams respond to theidentified risks associated with non-compliance with climate change legislation. Business cases are developed with the input ofregional managers. After evaluation, these initiatives drive compliance strategies; enhancing power utilization efficiencies, otherenergy efficiency projects, such as at our 3 major UK Gateway sites. These developments are in turn utilized as opportunities tosecure and enhance the organization’s reputation (and market share), by communicating our climate change management in publiclyavailable reports such as the CDP questionnaires.

Potential financial impact figure – maximum (currency)<Not Applicable>

Explanation of financial impact figureCarbon tax or cap and trade programs in the US do not currently apply to CenturyLink’s operations. However, in 2018 CenturyLinkemitted 278,819 tonnes CO2e as a result of fuel consumption in the USA. In 2018, CenturyLink would have been liable for a tax ofapproximately $12M in the U.S. if a tax had been imposed equal to the EPA’s estimated social cost of carbon of approximately$42/tonne (for Scope 1 emissions only).

Management methodCenturyLink monitors changes in regulation/policy and develop plans to manage the financial impact. The financial impact of newcarbon taxes and levies would be minimized by the energy efficiency and carbon reduction projects that CenturyLink implementsas a matter of course. For example, our response to Question 4.3a identifies the installation of building controls in US properties in2018. Regarding the cost of management, we already implement energy / carbon reduction initiatives which would contributetowards the management of this risks. However, we have calculated the cost of management based upon the identified cost of UScarbon reduction initiatives in 2018 (see answer to 4.3b) and an additional $50,000 to cover additional tax planning andmanagement. Note that we have focused on the USA with respect to this risk because we are already subject to carbon taxes inEMEA and therefore have not factored this in as an additional (i.e. future potential) risk. Our exposure in LATAM is relatively limitedgiven the far smaller consumption compared to the USA.

Type of financial impactIncreased capital costs (e.g., damage to facilities)

Company- specific descriptionClimate change brings increased risk of flood from extreme weather events and/or rising sea levels. Our operations depend on ourability to limit and mitigate interruptions or degradation in service for customers. Interruptions in service or performance problems,for whatever reason, could undermine confidence in our services and cause us to lose customers or make it more difficult to attractnew ones.


LikelihoodMore likely than not






Explanation of financial impact figureThe figure of $16,100,000 is selected as representative of the annual costs of acute weather events due to climate change. Thiswas the cost of repairs to damage caused during the 2018 Atlantic hurricane season.

Management methodOperational management strategy is to undertake a review of sites and establish which are at risk then commence a prioritizationprocess in order to address those locations at high risk. Risk is then managed by investing in network and buildings to protectagainst flood and other extreme weather events. For example, one building in York (UK) was vacated and assets migrated toanother location, in order to reduce exposure to flood risk. Other locations have been upgraded or redesigned to prevent flooddamage. Regarding the cost of management, We consider that in the medium term (4-10 years) that there is no additional cost ofmanagement (excluding repair and recovery) associated with acute/extreme weather events, being that our existing processesrelated to ensuring network reliability include planning for and mitigation of the effects of severe weather. These costs areBusiness-As-Usual (BAU) and are not tracked independently of other routine operating expenses.

Reputation: Increased stakeholder concern or negative stakeholder feedback

Type of financial impactReduced revenue from decreased demand for goods/services

Company- specific descriptionCenturyLink understands that part of its duty as a business partner and a ‘good corporate citizen’ is that of ensuring our customerscan rely on the positive reputation of the company. The risk of breaching such trust by adverse actions in respect of climate changeprotocols could result in reduced sales opportunities with existing or prospective customers. The relevance of such a risk isdemonstrated by the high level of importance attached to the value attached to GHG emissions management by our customers,many of whom request our submission of the CDP’s Supply Chain Questionnaire.


LikelihoodVery likely

Magnitude of impactMedium-low





Explanation of financial impact figureExplanation of the financial impact: If CenturyLink fails to meet the expectations of our customers and other stakeholders as itrelates to climate change mitigation activities the potential exists for those customers to reduce their spend with CenturyLink infavor of our competitors who are more closely aligned with their environmental sustainability objectives. For purposes of evaluatingthe potential financial impact of this risk, we estimated a 10% decrease in annual revenue from the median annual revenue of thosecustomers who request that CenturyLink participate in the CDP Supply Chain questionnaire.

Management methodManagement of the issue is part of the business as usual processes; honesty and Integrity being unifying principles of the company.No additional management cost is expected. As explained in Risk 1 above, CenturyLink routinely implements projects to enhanceenergy efficiency, and in Europe sources electricity from renewable sources. We have identified a variety of energy and carbonreduction initiatives that were active in 2018 in our answer to question 4.3b, for example the enhancement of motors and drives andcooling systems at US sites. Further projects were under investigation in 2018 and are now being rolled out. One such example,from Latin America, is the installation of solar panels on many of our POPs. The cost of management is based upon the cost ofreporting our response to climate change, in part through the calculation of our carbon footprint and reporting to CDP, as well asother sustainability reports. This is based upon internal hours and the cost of external third party support. Some associated costs inrespect of Environmental and Energy Management Systems (ISO 14001, ISO 50001) are included, the majority however beingconsidered Business as Usual. We have not included the cost of the energy efficiency initiatives as this is considered part of ourbusiness-as-usual cost. However, we have included the cost of some of our energy efficiency and carbon reduction projects in ouranswer to question 4.3a.

Company-specific descriptionIncreased business – as customers wish to reduce costs, improve efficiency, and reduce the environmental impact of theiroperations their increased use of telecommunications products to enhance virtualization, and reduce travel and communicationscost will be part of that strategy. Customers also increasingly wish to retain within their supply chain business partners with positivecredentials in respect of climate-change. CenturyLink’s challenge to meet the opportunity is to A: ensure that we bring to marketproducts which will enable businesses to achieve the aforementioned objective and B: continue to mitigate our impacts on theenvironment including achieving carbon emissions reduction targets.

Time horizonShort-term

LikelihoodLikely






Explanation of financial impact figureIn line with the description above, we consider that businesses are incentivized to adopt telecommunications as a substitute fortravel and physical products, and networked services such as Cloud storage where these provide further efficiencies. In this respectwe consider that our provision of these services, and our own adoption of low carbon energy sources, could generate additionalrevenue for the business. The Climate Risk Study for Telecommunications and Data Centre Services Prepared for the GeneralServices Administration by Riverside Technology, Inc and Acclimatise (2014) estimated the annual growth within the industry to be1.1%. The $23,000,000 figure identified above is a conservative estimate, estimated purely for the purposes of this questionnaire,and being approximately 0.1% of our 2018 revenue ($23,443,000,000), as being attributable wholly to improved reputation ofutilizing lower emission products and services thereby affecting environmental climate change.

Strategy to realize opportunityCenturyLink’s core business is built around providing telecommunications and networked solutions. We are therefore able togenerate business advantage, whilst meeting customers’ needs with sustainable solutions; telecommunications and online solutionscan reduce their footprint. An example is our service to Info Mart Corporation. Info Mart needed a secure reliable platform to makecertain their 300,000 customers would have access to their business applications 24/7/365. A custom private cloud solution provedto be the answer to keep their buyer’ and suppliers’ connections uninterrupted. Cloud computing data centers require lessinfrastructure and space compared with on-site servers, because they can optimize servers based on storage requirements. The

server utilization enhances energy efficiency directly, but also reduces the demand for energy for ancillary servers such as cooling,thereby reducing an organization’s carbon footprint. Regarding cost, the provision of telecommunications solutions is our coreservice, therefore there is no additional cost to realize this opportunity.

Type of financial impactIncreased revenue through new products and services related to ensuring resiliency

Company-specific descriptionClimate changes that increase severe weather events including changes in precipitation extremes and droughts will likely disruptbusiness travel, transportation of goods, and the provision of services by businesses. As businesses seek to mitigate these impactson their operations they will increasingly turn to Information and Communications Technology (ICT) and virtual solutions to avoid thepotential disruptive effect of climate change. As a provider of ICT services this change in physical climate parameters providesCenturyLink an opportunity through an increased demand for our network/connectivity services.


LikelihoodVirtually certain






Explanation of financial impact figureThe increased use of our telecommunications services, as a result of disruption of travel due to extreme climate change-inducedweather events is estimated as 0.1% of revenue. The $23,000,000 figure identified above is approximately 0.1% of the 2018revenue of $23,443,000,000.

Strategy to realize opportunityThe provision of CenturyLink's core service itself can be viewed as the 'management method', since greater uptake of this servicewill occur during disruption of transportation or displacement of households due to physical change brought about by climatechange. For example, research indicates that use of social media spikes during natural disasters which could increase in frequencyand severity due to climate change. For example, 75% of New Orleans residents responding to one survey visited online sitesspecific to their neighbourhoods after Hurricane Katrina. For the American public, mainstream media sites dominated, with 73% ofonline Hurricane Katrina news consumers turning to websites of major news organizations. One survey revealed that almost 50%of respondents communicated with those that they had not been in contact with for more than a year. The Internet was an importantoutlet for relief donations with 13 million Americans (9% of Internet users) going online to donate.

Type of financial impactOther, please specify (Corporate Reputation)

Company-specific descriptionIt is believed that CenturyLink may benefit directly from changing customer preferences in response to the stance we are taking onclimate-related issues. Our business customers already demonstrate a high level of awareness, and request information on ourmanagement and reduction of carbon emissions. We engage in a number of voluntary and customer driven reporting initiatives,including CDP, many of which are publicly available, and serve to demonstrate our good corporate citizenship in this respect. Sinceperformance with regard to climate change mitigation is often requested in the procurement process and monitored by existingcustomers, we anticipate we will see revenue increase to some degree, as a result, both through the expansion of existingcontracts and new business.


LikelihoodLikely






Explanation of financial impact figureThe estimated increase of $2,000,000 is based upon a 10% increase in the annual median revenue of those customers whorequest our CDP disclosure, being a representative sample of those who attach a high degree of importance to our management ofthese issues.

Strategy to realize opportunityManagement of the issue is part of the business as usual processes; honesty and Integrity being part of the unifying principles ofthe company. No additional management cost for energy efficiency is expected. As explained in Risk 1 above, CenturyLinkroutinely implements projects to enhance energy efficiency, and in Europe sources electricity from renewable sources. We haveidentified a variety of energy and carbon reduction initiatives that were active in 2018 in our answer to question 4.3b, for examplethe enhancement of motors and drives and cooling systems at US sites. Further projects were under investigation in 2018 and arenow being rolled out. One such example, from Latin America, is the installation of solar panels on many of our POPs. The cost ofmanagement is based upon the cost of reporting our response to climate change, in part through the calculation of our carbonfootprint and reporting to CDP, as well as other reports. This is based upon internal hours and the cost of external third partysupport. We have not included the cost of the energy efficiency as this is considered part of our business-as-usual cost. However,we have included the cost of some of our energy efficiency and carbon reduction projects in our answer to question 4.3a. Includedalso are elements relating to the cost of our energy management system registration (ISO50001).

(C2.5) Describe where and how the identified risks and opportunities have impacted your business.

Impact Description

Productsandservices

Impacted The products and services area of business is impacted by climate related risks and opportunities. As described above, our operations insome localities are subject to increased energy costs arising from carbon taxes and trading costs (e.g. CCL, EU ETS). We have respondedto this through energy efficiency projects and compliance strategies to minimize any impact upon the cost of our services. Also ofimportance are the opportunities arising from consumer and personal behavior that increases demand for virtualization of work and/orentertainment products and services has impacted CenturyLink as a provider of IP-based data, voice, and video services. Demand forCenturyLink’s existing products and services is expected to continue to increase over the long-term, allowing CenturyLink to capitalize onconsumers’ growing desire to dematerialize and utilize lower-carbon products and services in their daily lives. This factor is assessed ashaving a medium impact on the company.

Supplychainand/orvaluechain

Impacted With regard to our customers, consumer and personal behavior that increases demand for virtualization of work and/or entertainmentproducts and services has impacted CenturyLink as a provider of IP-based data, voice, and video services. Demand for CenturyLink’sexisting products and services is expected to continue to increase over the long-term, allowing CenturyLink to capitalize on consumers’growing desire to dematerialize and utilize lower-carbon products and services in their daily lives. This factor is assessed as having amedium impact on the company.

Adaptationandmitigationactivities

Impactedfor somesuppliers,facilities,orproductlines

Adaptation and mitigation activities are impacted by climate related risks and opportunities. The identified risk of climate change inducedflood events can also be viewed as an opportunity to ensure customers will continue to have reliable services, flood mitigation activities arebeing considered and performed in locations at risk of impact. Acute and chronic physical risk factors are taken into account whenevaluating existing infrastructure or new construction plans. This factor is assessed as having a small impact on the company.

Investmentin R&D

Impactedfor somesuppliers,facilities,orproductlines

Investment in R&D is impacted by climate related risks and opportunities. By the nature of the business/industry, CenturyLink is continuallyinvesting to optimize our products and services. By boosting efficiency of our products and services and decreasing energy consumption,CenturyLink can become more resilient to climate change, and enhance its reputation for good corporate governance.

Operations Impacted The operations area of business is impacted by climate related risks and opportunities. For example, we consider a significant impact fromcarbon taxes in the USA as unlikely in the medium term, but we are affected by carbon taxes at European sites. In the UK statutoryinstruments such as the Climate Change Levy and EU Emissions Trading Scheme increase the costs of procuring of natural gas andelectricity directly via taxes and indirectly through buying carbon trading allowances (see 11.1c). As a result we have implemented a varietyof energy savings projects such as at our UK Islington Gateway Site. This factor is assessed as having a medium impact on the company

(C2.6) Describe where and how the identified risks and opportunities have been factored into your financial planningprocess.

Relevance Description

Revenues Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to revenues. Overall, revenues can beincreased by capitalizing on opportunities that arise from a general trend among customers to seek low carbon solutions anddecarbonize the economy. Demonstraing our commitment to carbon emissions reduction therefore enables CenturyLink to be morecompetitive in the marketplace. Changing demands of customers and/or stakeholders for CenturyLink’s products and services, as drivenby climate change, therefore poses both risks and opportunities in relation to company revenue, which are considered during financialplanning and business strategy. These factors are assessed as having an impact of medium magnitude.

Operatingcosts

Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to operating costs. For example, there is arisk posed by the potential increase in costs from carbon taxes, whereas opportunities to reduce operating costs by enhancing energyefficiency present an positive opportunity for both the company and the environment as a whole. These risks and opportunities areprioritized and valued by CenturyLink. These factors are assessed as having an impact of medium magnitude.

Capitalexpenditures/ capitalallocation

Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to capital expenditures/allocation.Investment in energy efficient products, assets, or buildings in response to climate-change driven factors both incurs a cost (risk) in termsof capital expenditure, and an ongoing opportunity to reduce energy costs, operational expenditure. Capital expenditures for energyefficiency initiatives are ongoing with continual investment to reduce energy consumption and minimize carbon emissions. Our answer toquestion 4.3b identifies such expenditure in the 2018 calendar year. These factors are assessed as having an impact of mediummagnitude.

Acquisitionsanddivestments

Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to acquisitions and divestments. Acquiringthe risks of another business entity, related to climate change activities, prior to completion of the acquisition is a factor which must beconsidered by the purchasing company. As a minimum, these would include costs of energy purchase, energy efficiency measures,flood risks and reputational factors. For example, in the financial planning process leading up to the acquisition of Level 3, CenturyLinkconsidered risks associated with rising sea levels, and an increased frequency and intensity of storm surges and severe weather as itrelated to network operations. Similarly, if divestments were made, climate change risks and opportunities would be considered infinancial planning process. These factors are assessed as having an impact of medium magnitude.

Access tocapital

Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to access to capital. CenturyLink, as agood corporate citizen, strives to minimize climate change risks and enhance the opportunities presented by mitigation measures. This,in part, requires access to capital markets to ensure funding is available to meet the demands which are imposed by the increasedseverity of extreme weather events which can increase the potential of physical damage to our facilities. On both an acute and chronicbasis, the company must have sufficient access to capital to ensure any damages can be fixed so that the network experiences minimalimpact. Similarly, access to capital for preventative measures – such as flood, windstorm, wildfire resilience of facilities or assets - is animportant consideration as well. These factors are assessed as having an impact of low magnitude.

Assets Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to assets. Investment in efficiencyupgrades for existing assets and/or purchase of new energy efficient assets is taken into consideration since such investments canreduce operating costs while lowering the company’s carbon footprint. In order to mitigate climate aspects such as flood risk the locationof an asset is taken into consideration. These factors are assessed as having an impact of low/medium magnitude.

Liabilities Impacted Climate related risks and opportunities factor into the financial planning process as it pertains to liabilities. Increased severity of extremeweather events not only puts our facilities at risk of physical damage, but also puts our field-operations personnel at risk during potentialresponse activities. The business must consider the risk of increased liabilities due to increased employee injuries resulting from morefrequent emergency response efforts at facilities impacted by severe weather. By locating our assets in locations which have a reducedrisk of flooding, or enhancing flood mitigation measures, our liabilities can be reduced, for example as undertaken at a facility in York, UK.These factors are assessed as having an impact of medium/low magnitude.

CDP Page of 10317

C3.1c

(C3.1c) Explain how climate-related issues are integrated into your business objectives and strategy.

CenturyLink’s vision is to become the trusted connection to the networked world. Our strategy is Operational Excellence focused onour customers, investors, and employees. Our objective is profitable growth which we realize by providing a differentiated customerexperience, enhanced employee engagement, accelerated digital transformation, financial growth, and expansion of our addressablemarket. Our business strategy of Operational Excellence and the objectives noted above are all informed by climate-change relatedissues. In order to achieve Operational Excellence, CenturyLink must deliver reliable service to our customers at a competitive price.Our robust process for identifying, assessing, and managing risks related to climate change helps facilitate reliable and resilientnetwork services and provides a differentiated customer experience. Our continued investment in energy efficiency helps control ouroperating expenses and ability to maintain competitive pricing. Another way we integrate climate-related issues into ourstrategy/objectives is by establishing and communicating our Science-Based Targets for carbon emissions reduction. In addition tothe Science-based targets active in 2018, we now have further SBTi-approved Science-based Targets set in 2019 2019, to helpachieve the goal of preventing global mean surface temperatures exceeding 2 degree C above pre-industrial levels. This is asubstantial business decision backed in part by significant investments to improve heating, ventilation and air conditioning plant inNorth America. Another substantial business decision is our strategy to maintain certification to ISO 50001 and ISO 14001 withinregional operations in EMEA to improve energy efficiency and effectively manage our environmental impacts. These systems furthersupport Operational Excellence, a differentiated customer experience by aligning with their environmental sustainability values, andenhances employee engagement by demonstrating a commitment to being a good corporate citizen.

C3.1g

(C3.1g) Why does your organization not use climate-related scenario analysis to inform your business strategy?

Our responses to climate change are integrated within our corporate contingency planning protocols. These are developed toaccount for specific risks. Flooding hurricanes, wildfires and other extreme weather resulting in loss of facilities, suppliers, andemployees are examples of the scenarios envisaged. Our prime objective is the protection of services to ensure that critical nationalinfrastructures are protected during such events, and extensive plans are in place to ensure that our services to governmental (andcommercial) customers are maintained. One example of our planning for business continuity in respect of climate change relates toa site in York, UK. This was relocated to provide enhanced protection from river flooding, which is linked to extreme rainfall eventsrelated to climate change. The magnitude of these events is related to the river basin and its management and the magnitude ofrainfall. The standard of flood protection is dictated by this and legislative requirements, and is therefore not dependent on planningagainst emissions pathways. This therefore is the corporate strategy in respect of the risks to the infrastructure, ensuring that eachlocation is subject to a contingency plan which includes but is not limited to the scenarios of climate change. We anticipate usingscenario analysis in the next 2 years. At present processes are being considered to enhance our methodology currently in use to beable to include scenario based analysis. This has been allocated to the Environmental Sustainability Manager to further evaluate forimplementation.

(C4.3c) What methods do you use to drive investment in emissions reduction activities?

Method Comment

Dedicatedbudget forenergyefficiency

Reduction of energy usage is a top priority to meet budget goals. Potential improvements are assessed by our Energy Management teams whodevelop a cost benefit analysis for approval.

Dedicatedbudget forotheremissionsreductionactivities

The procurement of zero carbon renewable-sourced electricity is used to reduce emissions of CO2e throughout locations in Europe. We procurerenewable electricity for most of our consumption in the following countries: - UK, France, Germany, Spain, Italy, The Netherlands, Belgium andSweden.

Employeeengagement

Through our Corporate Social Responsibility program we seek to engage our employees in a variety of "Cause" areas including environmentalsustainability. Employees are encouraged and provided with resources through a variety of communication platforms to enact numerous small scaleactions to promote energy efficiency, cost savings and carbon reduction. One example, in the USA is the provision of free to operate chargingstations for electric and plug-in hybrid vehicles used by employees. In the UK, there is a incentive for car sharing and cycle-to-work schemes

% revenue from low carbon product(s) in the reporting year69

CommentAn example of how we have evaluated the carbon reduction impacts of using ICT is provided below. For example, (using 2012emission factors) a hypothetical company with 20 office workers and 20 maintenance engineers (primary drivers), may have vehicle(car and van) emissions of 145 tonnes CO2e/pa in 2012. (2800 litres of gasoline at 2012 DEFRA emission factor of 2.2423 kgCO2e/litre AND 53500 litres diesel at 2.584 kg CO2e/litre). By reducing mileage and fuel use by 10% through increased use oftelecommunications, emissions would be reduced by 14.5 tonnes pa. Such an example is transferable to other companies butwould vary according to the nature of their business. Level 3 is not planning to originate any credits for this.

Business travel



Emissions calculation methodologyThis comprises travel in employee owned vehicles and short term rental cars (19,458.55 tonnes CO2e) and air travel in commercialaircraft (2,925.96t). Car travel is calculated from expenses claims or other internal records which show either distance travelled orfuel consumption. Air travel is calculated using the booking agents’ data including distances, or calculating these using software.The distance is then multiplied by the appropriate emissions factor, as identified elsewhere and GWPs where relevant. Forexample, in Argentina records show company cars consumed 21,201.82 litres of diesel. This was multiplied by the DEFRAconversion factor (diesel average biofuel blend) of 2.6269 kg CO2e/litre, giving 55.70 tonnes CO2e from this category in Argentina.

Employee commuting



Emissions calculation methodologyFuel consumption, commuting distances and modes of travel were based on survey results from our employee operations in LatinAmerica. Total emissions by fuel type and mode of transportation were calculated using emission factors and methodologies fromthe US EPA Emission Factors for Greenhouse Gas Inventories, Mar 2018. Total emissions from employee commuting wereextrapolated to legacy CenturyLink employees (9,980 tCO2e) and legacy Level 3 employees (2,550 tCO2e) to determine thecomprehensive global total. Global Warming Potentials (GWP) are from the IPCC Fourth Assessment Report.


ExplanationSurvey results were obtained for CenturyLink employees in Latin America which represent approximately 5% of the total workforce.Emissions were estimated for the remainder of the company assuming similar commuting patterns.

Upstream leased assets



Emissions calculation methodologyCenturyLink follows the Operational Control approach and because it has control of its leased buildings these emissions areincluded in the Scope 1 and Scope 2 totals. However, there is an exception to this are where CenturyLink houses its equipment inco-location sites which are managed by 3rd parties. Emissions from these sites are included in this Scope 3 category. For example,in the UK 10,501,307 kWhs are consumed by CenturyLink equipment in third party co-location (TPC) sites once a Power UtilizationEfficiency (PUE) of 1.7 applied. This electricity consumption is multiplied by the DEFRA UK electricity emission factor of 0.28307 kgCO22/kWh, which gives emissions of 2,973 tonnes CO2e from TPCs in the UK.

Reason for changeThe 9.59% increase in tonnes CO2e per unit revenue compared to 2017 is due to both a rise in absolute emissions and a smalldecline in revenue. In the period, Scope 1 & 2 emissions (location-based) increased by 21,907.44 tonnes CO2e, whereas (in thereported countries) revenue declined. Therefore, the emissions intensity per unit revenue rose due to both of these factors.Although emissions reduction projects (described in 4.3b) accounted for avoidance of 12,603.37 tonnes, even with this taken intoaccount, Scope 1 & 2 emissions rose elsewhere (equivalent to +34,510.81 tonnes CO2e) giving the overall increase of 21,907.44tonnes CO2e.

All renewableenergy consumption is supported by Guarantees of Origin. We also purchase renewable energy in Sweden, although this is notreported here (in section 8) as the supplier was not able to provide GOs. A low carbon emission factor has not been applied to Italywhich uses electricity generated from 'renewable biogas from agriculture. This is because the Greenhouse Gas Protocol advisesthis should not be considered carbon neutral and we were unable to obtain a supplier specific (or other) emission factor. Therefore,this electricity was treated at the grid factor (Location basis) or residual mix factor (Market basis). As part of our ISO14001commitment to continual improvement, we will seek to obtain data from the relevant suppliers for our 2019 carbon emissions whenresponding the CDP’s climate questionnaire in 2020.

CommentThe Islington Gateway site in the UK is covered by the EU ETS. The site emitted 126.91 tonnes CO2e from natural gas combustionand 73.61 tonnes CO2e from diesel combustion in back-up power generators. These emissions total of 200.52 tonnes CO2e in theEU ETS emissions verification report. Total scope 1 emissions are 286,602.90 tonnes CO2e, therefore those covered by the EUETS are 0.07% of Scope 1 emissions.

CommentWe have Climate Change Agreements at 3 major sites in London, 2 of which are owned and 1 of which is leased. The target is inthe form of a Power Utilization Efficiency (PUE) and both electricity and diesel are reported and verified. A target PUE of 1.580275was set, whereas this was narrowly missed with a PUE of 1.589366 being achieved. Since the target and performance are basedon PUE, emissions per se are not verified, therefore we have entered 0 in this field. Due to missing the target PUE CenturyLinkpurchased 392 allowances, based on an excess of 392 tonnes CO2e. These relate to both scope 1 and scope 2 emissions, andbecause of the nature of the CCA report, those relating to just Scope 1 cannot be identified. Please note that the carbon emissionswhich form the basis of our CDP questionnaire responses are verified, but we have interpreted the field for 'verification' in thisquestion as relating to verification by the CCA consultant and administrator.

CommentThe cost is £218,975 for electricity (some sites are exempt from the tax), and £6,705 for natural gas, a total of £225,680. Somesites are exempt from the tax because they hold Climate Change Agreements, and they have been excluded from the calculations.In calculating the percentage of emissions covered by the tax, we are using a location-based approach, and excluding emissionsfrom exempted facilities.

C11.1d

(C11.1d) What is your strategy for complying with the systems in which you participate or anticipate participating?

Presently emissions trading systems do not affect our facilities in the USA. If future regulations are enacted and require thatCenturyLink develop a program in the United States, CenturyLink will develop a procedure to assess applicability and a process toensure compliance.

Such systems do affect a few of our facilities in the UK. Our strategy for complying with both the EU ETS and our Climate ChangeAgreements is to continually enhance the energy efficiency (including the power utilization efficiency) of our major sites to meet thetargets. If targets are not met, then we purchase allowances to ensure compliance. The 3 company sites covered by Climate ChangeAgreements (CCA) consume approximately 61% of UK electricity, whereas the most significant of these, in Islington, dominates UKnatural gas consumption. All three have back-up power sources which are reportable but are not significant sources of CO2e. Thesesites are monitored using a portal that allows remote viewing of current and all historic kWhs and CO2e. The sites are half hourlymetered and can be monitored at the same frequency. This allows analysis of trends and provides the opportunity to identify anyunusual consumption. CenturyLink has EU Code of Conduct Participant Status and is certified to the international standard in EnergyManagement Systems ISO50001. CenturyLink uses power smoothing devices (power factor correction) and implements a variety ofprojects to enhance Power Utilization Efficiencies, covering lighting and cooling systems. One example is chiller fan upgrades atIslington in 2017. Energy efficiency is also delivered through selecting equipment based on its lifetime power consumption, switch-offs and consolidation projects to avoid excessive demand. The impact of energy reduction initiatives is shown in monthly UtilityReports, whereas the predicted savings from infrastructure related projects (i.e. power provision, cooling, lighting etc) are illustrated.

Regarding our other sites, affected only by the Climate Change Levy, these too undergo improvements for energy efficiency. The 3major sites identified above are exempt from the Climate Change Levy because they are covered by Climate Change Agreements.

% Scope 3 emissions as reported in C6.52.59

Rationale for the coverage of your engagementOur rationale is to better understand our electricity suppliers' generation portfolio and goals in limiting and/or reducing greenhousegas emissions. This allows CenturyLink to better evaluate our own opportunities for switching to renewable/green tariffs. Wedecided to approach our power suppliers because of the considerable impact this could have upon our emissions of CO2e; notethat although this accounts for 2.65% of Scope 3 emissions, it also represents engagement with companies that supply power thataccounts for 18.76% of our Scope 2 (location-based) emissions (see Comments for the calculations).

Impact of engagement, including measures of successThe impact of engagement has been to improve our own understanding of opportunities for potentially switching to renewable/green tariffs. Measures of success include being able to quantify reductions in our Scope 2 electricity (market-based) emissions ofCO2e that would arrive with such a switch, and being able to present this as part of a business case.

CommentWe have engaged with electricity suppliers representing an estimated 20% of our US supply. This forms the basis of the 20% figureused above. US Scope 3 electricity emissions are 282,149.21 tonnes CO2e, of which 20% is 56,429.84 tonnes CO2e. Theengagement therefore represents 2.65% of our Scope 3 emissions (i.e. 56,429.84 is 2.59% of 2,178,503.86). Please note however,that these suppliers also supply power responsible for emissions of 369,769.25 tonnes CO2e (i.e. 20% of USA Scope 2 electricity,location-based). This is equivalent to 18.72% of our total global Scope 2 (location-based) emissions i.e.(369,769.25/1,975,165.06)*100 = 18.72%.

Please explain the rationale for selecting this group of customers and scope of engagementCenturyLink, in 2017, continued its voluntary participation with cable, satellite and telco service providers and set-top boxmanufacturers in the Voluntary Agreement for Ongoing Improvement to the Energy Efficiency of Set-Top Boxes. The agreementstipulates that at least 90 percent of all new set-top boxes purchased and installed beginning Jan. 1, 2013, will meet the U.S.Environmental Protection Agency Energy Star 3.0 efficiency levels (“Tier 1” standards). In addition, it stipulates that set-top boxesprocured beginning Jan. 1, 2016, must meet more efficient standards (“Tier 2” standards). An independent report by D+RInternational “shows that the voluntary agreement has already saved consumers $2.1 billion and avoided 11.8 million metric tons ofCO2 emissions over its first four years through 2016. Annual savings are expected to top $1 billion in 2017 alone due to thecompleted implementation of a second tier of tightened energy efficiency commitments.”

C12.1c

(C12.1c) Give details of your climate-related engagement strategy with other partners in the value chain.

CenturyLink has also established an engagement strategy with our employees who are also partners in the value chain. TheEnvironmental Sustainability team provides periodic updates (written correspondence) to employees on climate change mitigationand other environmental sustainability performance measure and accomplishments. We also hold collaborative events with ouremployees sponsored by functional groups within the company with direct responsibility for programs that improve environmentalsustainability. Our "Going Green" initiative allows employees to make suggestions to the EHSS Team, whereas our Green Tip Board,an internal platform, allows employees to share sustainability ideas.

One example of engaging our employees is the expansion of our electric vehicle charging infrastructure. The number of chargingports at our Broomfield CO US location was doubled in late 2018, allowing the simultaneous charging of up to 8 cars. 9,470 chargingsessions were made in 2018 demonstrating the success of this collaborative opportunity with employees. This has saved 35 tonnesCO2e.

CenturyLink also seeks to collaborate with employees through offers on commuter transport. We support schemes in Seattle,Portland, Phoenix and Denver. For example, we work with the Denver Regional Transport District to offer commuting employeesdiscounted monthly travel.

Involvement in organizations such as trade associations is assessed prior to active participation. CenturyLinks' Public Policy Group isalso engaged if changes or new initiatives may have an impact on regulatory or public policy for the company.

A further means of ensuring actions that can influence policies remain consistent with our climate change strategy is achievedthrough the Environmental Sustainability Team. This Team includes the functional groups that would be involved directly or indirectlyin influencing public policy related to climate change. Consistency is achieved, in part, through consultation with our ChiefCompliance Officer and General Counsel (as needed). In general, public policy activities are geared towards increasing andexpanding the adoption of broadband internet which can significantly reduce the carbon footprint of our customers and their businesspartners.

Major sources of emissionsScope 1 emissions are generated from natural gas combustion in properties (12.87%), fuel combustion in companyowned/controlled cars (49.52%), fuel combustion in company jets (1.31%), refrigerant losses (8.17%) and the combustion of fuelfor other uses, predominantly in emergency generators (28.12%).

VerifiedYes

Allocation methodAllocation based on the market value of products purchased

Please explain how you have identified the GHG source, including major limitations to this process and assumptionsmadeAn operational control boundary was selected according to the Greenhouse Gas Protocol methodology. Therefore, all fuelcombustion and refrigerant loss under the organization's direct control are included in Scope 1. Fuel consumption waspredominantly taken from invoices and is therefore accurate for natural gas combustion in buildings and for road vehicles. We havealso used this approach for fuel combustion in back-up generators and other uses. Data on refrigerant losses are gathered frommaintenance records, with guidance given to engineers to ensure accurate reporting. The limitations associated with thesetechniques have been quantified as a percentage uncertainty, being approximately 2%. This uncertainty allows for someinaccuracy in calculating refrigerant loses. It also includes uncertainty associated with calculating emissions based on fuelconsumption records, and the need for extrapolation in limited instances, and a recognition that some fuel may remain notcombusted in the reporting period.






Uncertainty (±%)2

Major sources of emissionsThe CO2e figures reported in this answer are generated using a location-based approach. Electricity consumption accounts for98.74% of the reported CO2e, the use of supplied heat & steam accounts for 0.32%, whereas chilled water accounts for 0.94%.

The remaining4.87% of electricity-related emissions are from sites where floor area is not known, therefore we allocate kWhs based upon theirfunction and our knowledge of consumption across the portfolio. These techniques are identified in a procedure, ensuring theirconsistent application. We therefore consider the overall uncertainty associated with Scope 2 (market-based) emissions to beapproximately 2%.

Please explain how you have identified the GHG source, including major limitations to this process and assumptionsmadeAn operational control boundary was selected according to the Greenhouse Gas Protocol methodology. Therefore, all fuelcombustion and refrigerant loss under the organization's direct control are included in Scope 1. Fuel consumption waspredominantly taken from invoices and is therefore accurate for natural gas combustion in buildings and for road vehicles. We havealso used this approach for fuel combustion in back-up generators and other uses. Data on refrigerant losses are gathered frommaintenance records, with guidance given to engineers to ensure accurate reporting. The limitations associated with these

CDP Page of 10365

techniques have been quantified as a percentage uncertainty, being approximately 2%. This uncertainty allows for someinaccuracy in calculating refrigerant loses. It also includes uncertainty associated with calculating emissions based on fuelconsumption records, and the need for extrapolation in limited instances, and a recognition that some fuel may remain notcombusted in the reporting period.

Please explain how you have identified the GHG source, including major limitations to this process and assumptionsmadeUsing an operational control boundary, electricity use in buildings controlled by CenturyLink is classed as Scope 2, whereaselectricity consumption by equipment housed in 3rd party 'co-location sites' is classified as Scope 3. A market-based approach wasused for the allocation in this question. Electricity accounts for vast majority of our Scope 2 (market-based) emissions. Of this themajority (86.23%) is directly metered and consumption is recorded in our energy management systems and accountancymanagement systems, facilitating the interpretation of consumption and, if required, normalization to calendar year i.e.annualization. For unmetered sites we use other techniques to estimate kWh consumption. Site representing 8.90% of electricity-related emissions have consumption calculated based on their floor area and a kWh/m2 metric, which is dependent upon the site’sfunction, and generated by a knowledge of our sites including kWh/unit area design specifications for technical sites. The remaining4.87% of electricity-related emissions are from sites where floor area is not known, therefore we allocate kWhs based upon theirfunction and our knowledge of consumption across the portfolio. These techniques are identified in a procedure, ensuring theirconsistent application. We therefore consider the overall uncertainty associated with Scope 2 (market-based) emissions to beapproximately 2%. This covers the uncertainties associated with annualization and the calculations for sites without recordedconsumption.

SC1.3

(SC1.3) What are the challenges in allocating emissions to different customers, and what would help you to overcome thesechallenges?

Allocation challenges Please explain what would help you overcome these challenges

Customer base is too large and diverseto accurately track emissions to thecustomer level

Because CenturyLink is a service provider and customers may utilize their own equipment etc. an exact number based onthe numerous products used to provide services would be difficult. We have allocated emissions based on revenue forthose customers that have requested.

SC1.4

(SC1.4) Do you plan to develop your capabilities to allocate emissions to your customers in the future?No

SC1.4b

(SC1.4b) Explain why you do not plan to develop capabilities to allocate emissions to your customers.

CenturyLink currently has sufficient capabilities to allocate emissions using a market value approach. We do not believe theinaccuracy associated with a market value allocation technique to be significant. Therefore, we have no plans at this time to furtherdevelop our capability to allocate emissions.
