1. Introduction
The government has national and international commitments to reduce greenhouse gas emissions and the infrastructure sector has a key role to play in this. As the government company tasked with operating, maintaining and modernising England’s motorways and major A-roads, Highways England has an important role to play in helping the government meet their commitments. We have been collecting data on carbon emissions from our supply chain construction and maintenance contractors since 2008/09 through our carbon accounting tool. This process has allowed us to build up a database of carbon emissions for the construction and maintenance activities undertaken on our road network. A significant programme of road building was announced in 2014/15, and this time has also seen substantial changes as we moved to becoming “Highways England”. The 2015-2020 period is a significant time for road improvements, however these projects will have carbon emissions associated with them. As we embark on this exciting period, we want to build on our previous work of measuring our supply chain’s carbon emissions, by starting to manage carbon emissions. To achieve our ambitions, it’s important to us that our supply chain is brought on board. We have developed a new carbon tool to enable us to better manage the carbon emissions resulting from maintenance and improvement of our network. This guidance document accompanies this new tool. As one of our supply chain members, you are required to complete the carbon tool as completely and accurately as possible for the entirety of the contract or project which you are contracted for. The data you input into the tool is known as your 'Carbon Return'. These Carbon Returns are then sent to our team at Highways England on either a quarterly or monthly basis where they are processed to allow us to report to the government. This guidance document is intended to be a concise and informative guide containing to all the information you will need to collect the correct data and use our carbon tool.

2. Data Collection Process
It is important that you provide us with prompt and accurate carbon returns. The new tool is designed to make the data collection process as simple as possible. This includes:
Keeping all returns in one tool; Designating responsibility; Timescales; Pro forma to gather data; Improving awareness; and
Enabling accuracy.
The Tool The carbon tool is based in Microsoft Excel (Excel), and all of your data will be collected in one Excel file. This Excel file is to be used by all construction and maintenance contractors in our supply chain. When the data has been entered into the tool you will need to send it to the Highways England where the carbon returns are then processed and interpreted. Responsibility Our supply chain are responsible for providing us with monthly or quarterly returns (depending on your preference) which are completed as accurately as possible. Each project or contract should have a designated person or persons for completing the carbon returns and sending these back to Highways England. Whoever is designated will be responsible for the following:
Reading this guidance document;
Collecting the required data;
Keeping records of the data sources used;
Inputting the data into the carbon tool; and
Sending the completed tool output to our Highways England’s. Depending on your role, or the projects you are working on, you may be submitting data for more than one office or site. However, only one file is to be sent per contract per reporting period. In some instances, multiple contracts may form part of a larger scheme. In these cases it may be suitable to combine multiple contracts into one carbon return. However, this should be agreed with Highways England. You must keep copies of the data sources that you use to complete the tool. Examples of sources could be delivery notes, invoices, receipts, bills, waste transfer notes or similar. We may be required to check the carbon returns for errors every now and again, and may need to look at these records.
Highways England
Carbon Tool Guidance Page 5 of 29 Created: 24/04/15
Timescales Data can be sent to Highways England on either a monthly or quarterly basis, whichever it most convenient for you. Quarters are based on the financial year as follows:
Quarter 1 – April, May, June;
Quarter 2 – July, August, September;
Quarter 3 – October, November, December; and
Quarter 4 – January, February, March. Gathering data To gather all of the information required to complete the carbon return, you are likely to need to speak to a number of staff spread across a variety of disciplines and locations. It may also be necessary for you to contact sub-contractors and your suppliers directly, to obtain data which is not available directly from your colleagues. Further guidance on this is provided in Section 3. To assist you with collecting and recording the required data, a pro forma has been developed, and is provided in Appendix 1 at the end of this report. Data categories The tool is split into ten categories largely based upon the Specification for Highways Work. Each of these categories will have drop down menu’s from which you can select the items appropriate to your contract or project. To make data entry easier for you, data will be collected in the most sensible units, for example: kilowatt hours (kWh), kilometres (km), tonnes, cubic metres (m3) among others. It is essential that you record the data in the correct unit of measurement (this is shown in the tool and the pro forma). Raising staff awareness
At a very early stage in the project, before you commence with data collection, it would be good practice to inform your colleagues that you are likely to require input from them at some stage of the project or contract. It may also be a good time to provide these colleagues with the pro forma, so that they understand what data they will need to provide. Advance warning should help provide a more co-operative and efficient data collection process.

Data accuracy
We are striving to collect the most accurate data possible for the carbon emissions of our supply chain. To achieve this, where possible all your data should come from reliable and auditable data sources. However we understand that in some instances estimation may be required. Where this is the case, data should be based upon professional judgement and should be as representative as possible. If the exact item you have is not listed in the tool, either pick the closest item to it or if you have the information available please input your own carbon factor, details on how to do this are given in Section 4 of this guidance document.

3. Data to be Included
The data required by the tool is split into categories largely based upon the Specification for Highways Works. These categories help you to see where materials, and the carbon emissions associated with them, are used across a construction or maintenance contract, In turn this helps us to see where we should focus the our carbon management efforts. This section will help to clarify what items you should include in each of these categories. The data required in the tool is summarised by the diagram at the end of this section.
Data Categories
The tool requires you to enter quantities of all the materials delivered to site. Once quantities of these materials have been entered, the tool calculates the carbon emissions associated with them. Categories 1-7 can be considered as materials and categories 8-10 can be considered as non-materials:
1. Bulk Materials
2. Earthworks
3. Fencing, Barriers and Road Restraint Systems
4. Drainage
5. Road Pavements
6. Street Furniture and Electrical Equipment
7. Civil Structures and Retaining Walls
The tool also has categories for non-material sources of carbon emissions as shown below:
8. Fuel, Electricity and Water
9. Business and Employee Transport
10. Waste
Materials
Any material, or items, delivered for the construction or maintenance activity (see Appendix 1 for a full list) which you are undertaking should be included in the tool. You should use data sources such as delivery notes, invoices, bills, receipts or similar. The tool calculates carbon emissions by multiplying the quantities you enter by a ‘carbon factor’. These carbon factors can be viewed in the tool, and if necessary, you are able to enter your own “custom carbon factor”. Section 4 of this guidance document provides further details on this. Material Transport
In addition to the quantity of material delivered, you must also enter the distance the material has travelled. This should be from where the material is being delivered from
Materials
Highways England
Carbon Tool Guidance Page 8 of 29 Created: 24/04/15
(your supplier) to where the delivery vehicle “places” it (this could be at your construction site or a storage depot within your maintenance area for example). The tool captures the return journey, but you only need to enter the distance from your supplier to your site. The tool will calculate the rest. The onward emissions from transport of materials around your own site or maintenance area will be covered by entering your fuel use in the Fuel, Electricity and Water category. Bulk Materials The first category you will see in the tool, “Bulk Materials”, contains items which are likely to make up a significant proportion of the overall carbon emissions. Because of the relative importance of these materials to your carbon return, this category requires some extra detail compared to the other categories. You will still need to enter the quantity of bulk material used, and the distance it was transported, but you will also need to provide estimates as to where these materials were used on site, and also provide a forecast of the quantity to be delivered for the next reporting period. Assigning Bulk Materials You will need to assign the percentage of materials you have entered in the bulk materials category to the other categories in the tool. This is covered in detail in the step by step guide in section 4 of this guidance document Forecasting Bulk Materials The bulk materials category also requires you to forecast the amount of materials you are likely to have delivered in the next return period. Forecasts should be based upon the contract programme and/or discussions with colleagues about their planned activities in the next quarter or month. Whilst it is appreciated that this will be an estimated value, the best available information you have should be used. Business and Employee Transport
There are two items in the business and employee transport category, All transport relating to business must be recorded in the ‘Business Transport’ option and all transport relating to employees transport to site must be recorded under the ‘Employee Commuting’ option. The “Business and Employee Transport” Section requires you to enter the transport distance of all vehicles involved in the reporting contract for business purposes. This includes all business travel required for the contract which you are working on. Employee transport requires you to enter the distance travelled by all employees from their place of residence to your site. You should include both those directly employed by the reporting contractor and tier 1 subcontractors working on your site. If this data is not currently recorded by the reporting contractor, you may have to conduct a short survey of staff on site (or a sample of) to ascertain the required information or make an estimation based on the best available information.
Highways England
Carbon Tool Guidance Page 9 of 29 Created: 24/04/15
Fuel, Energy and Water
Fuel You should include all fuel delivered to your site for use in all plant and buildings on site or in the maintenance area. Energy – Buildings If you are the reporting contractor for a construction project, you will need to record the electricity and water used in all buildings on site. This includes the site office, on-site accommodation and any other buildings on the site involved in the contract. This includes those that are directly operated by you the contractor and those operated by subcontractors. Any buildings owned by the reporting contractor but not at the construction site are not included, for example head offices. If you are the reporting contractor for a maintenance area, you will need to record the fuel, electricity and water from all buildings in the maintenance area involved in that contract. This includes site offices, storage depots and all other buildings in the area involved in the contract. Any buildings owned by the reporting contractor but not within the maintenance area are not included, for example head offices. Water You should include all water purchased for use in construction/maintenance activities and water used in welfare facilities. This includes metred, tankered and abstracted water. Waste Disposal and Transport
All waste exported off site should be included in the tool. You will need to record which type of waste it is (see Appendix 1 for the types of waste), how it was disposed of and the distance between your site and the treatment facility. The tool will automatically calculate a return journey, so only include the one way distance.

4. Using the Tool
This section of the guidance will provide you with an overview of the tool and a step by step guide to inputting your data. When using the tool for the first time it is please refer to this guide. Overview of the Tool
The carbon tool is centred around the 'Home Page’; from there you can create your 'Carbon Returns'. You are able to enter the data as and when it becomes available to you. You can save a return, and resume it the following day to continue your data entry. This means that you don’t have to enter all of the data in one go. Once you have started or resumed your carbon return you will see a number of buttons at the top of the page. These will take you to the ten data category pages where you need to enter the data. These have already been shown in Section 3, but as a reminder, these are:
1. Bulk Materials
2. Earthworks
3. Fencing, Barriers and Road Restraint Systems
4. Drainage
5. Road Pavements
6. Street Furniture and Electrical Equipment
7. Civil Structures and Retaining Walls
8. Fuel, Electricity and Water
9. Business and Employee Transport
10. Waste
If you know that your project or contract does not involve one of these categories then you can ‘switch it off’ by clicking the category title in the table on the home page. Once you click the category it will turn the cells below that category grey, indicating that data is not required for this category in carbon returns you submit. All cells that have purple formatting require you to input data. Some of these will be drop downs that require you to select an option; others will require you to input a number or some text.
The following pages provide a step by step guide for you to follow to enter the data into the tool.
Cells of this colour require data to be added

Step 1) Enable Macros
The first step is to enable macros. Just click the 'Enable Content' button on the yellow banner at the top of any page when you first open the tool. Once you have clicked this button, the banner should disappear and you can begin using the tool.
NB: If the yellow banner does not appear this will be the result of your Excel settings. Either your excel automatically allows macros, in which case you do not need to do anything and should move to Step 2, or your Excel automatically disables macros without informing you. If the latter, you will need to click File > Options > Trust Centre > Trust Centre Settings > Macro Settings > Disable Macros with notification. Close and re-open the document and follow Step 1 as normal.
Click ‘Enable Content’ button
Highways England
Carbon Tool Guidance Page 13 of 29 Created: 24/04/15
Step 2) Project Details
Now that you have enabled macros, the buttons at the top of the page will work. These buttons will allow you to move between pages in the tool. You will notice that in addition to this guidance document, there is a separate guidance page within the tool. You should quickly read the in-tool guidance to refresh your knowledge of the tool, and refer to it at any point which you get stuck. After reading the guidance, the first page you will need to visit to begin your carbon return is the 'Home Page'. Here you will find a short list of project information questions which requires you to enter some answers as text and select other answers from the drop downs menus. These questions can only be filled in once per contract/project and cannot be edited once you have started to enter your data. This includes the choice of entering your carbon returns monthly or quarterly; once you have chosen you will be locked into monthly or quarterly reporting for the duration of the project or contract.
Some of the cells will require only one answer, for others it may be necessary to select all the answers that apply. For example, your project may involve both construction of both a new road and a new bridge structure. The final question asks how many lane km are constructed or maintained. For maintenance this will include all lane km involved in the contract. For example if you are maintaining 50km of 4 lane motorway and 100km of dual carriage way or both directions of travel, the total would be 800 lane km of maintenance ((50x4)+(100x2) x2). For construction please include all new lanes constructed, but please do not include lanes on the stretch of road that are not part of the construction or only subject to minor works. For example for a widening or smart motorway project, please include the length of new lanes created or the hard shoulder converted but not the other lanes where only minor works will take place.
Click each cell in the project details section and enter the required information. Note: the contents of the table may alter as you enter data to ensure you are only asked for the applicable data for your contract.
Highways England
Carbon Tool Guidance Page 14 of 29 Created: 24/04/15
Step 3) Create a Carbon Return
Next, from the 'Home Page' you will need to click 'Create New Carbon Return'. This will bring up a box where you will need to select the relevant month or quarter for which you are reporting. This will then appear as a line in the table on the Home Page. As your project or contract progresses and you enter multiple Carbon Returns, they will all be saved here. Once you have created a Carbon Return you can close the tool down, re-open it and enter your data into the tool at any time by clicking resume.
The red line around the carbon return shows which return you currently have loaded, as you add multiple returns this will help you keep track of which return you are inputting data into.
Click the ‘Add new return’ button and your new carbon return will be added to the table below. The red line signifies which return you currently have open. This will be useful once you have multiple returns saved in this file.
Highways England
Carbon Tool Guidance Page 15 of 29 Created: 24/04/15
Step 4) Inputting Data - Start With Bulk Materials
Now that you have created a Carbon Return, you must enter the data into each of the pages which are accessible from the second row of buttons at the top of the page. You should start with the bulk materials page. This contains the materials which are likely to make up a significant proportion of the overall carbon emissions. For each material click ‘standard carbon factor’ under the ‘add new row’ heading and enter the information required in the purple cells. Standard carbon factor
If you believe you have a more accurate or representative carbon factor than the one shown in the tool, you can click the ‘custom carbon factor’ button which will allow you to put your own carbon factor. More of the cells in the row turn purple, and you should enter information in to each of these, including the methodology as to where the factor came from and why it has been used. Custom carbon factor
Once you have entered all your data into the bulk materials category, click the ‘mark page complete’ tick box.
Some cells will require you to select an option from a drop down list
Some cells will require you to enter a number

Carbon Tool Guidance Page 16 of 29 Created: 24/04/15
Step 5) Bulk Materials - Forecasting and Assigning to Other Categories
The Bulk Materials category works slightly differently to the other 9 categories in the tool. It requires two extra steps as shown below. These steps will not be required in the rest of the tool. Assigning materials to the other categories You will need to assign the percentage of materials you have entered in the bulk materials category to the other categories in the tool. For example out of 100 tonnes of concrete delivered during a given period, 20% might have been for drainage, 30% for road pavements and 50% for structures. This data will then be carried over to the appropriate categories, so that you are reminded of the materials which you have already entered. This saves you time so you don’t need to input these into each category separately. You should do this using the best available information you have, or an estimation based on the works being undertaken in the period you are reporting. Concrete elements made on site using wet concrete, for example a slip formed concrete step barriers or an in-situ concrete pile, do not appear as item options in the tool. These items are captured by assigning the bulk materials to the relevant category. Forecasting Finally, you will need to forecast how much of the bulk materials you are likely to have delivered in the next reporting period. For example you may have had 100 tonnes of asphalt delivered during the current quarter/month and be expecting approximately 200 tonnes for the next quarter/month.
Input an approximate % of the material used in each category here.
Input the approximate quantity of the bulk material expected next quarter/month
Highways England
Carbon Tool Guidance Page 17 of 29 Created: 24/04/15
Step 6) Complete Carbon Return
Once you have entered all the data into the bulk materials page, you can proceed to complete the other 9 categories. Each of these will follow the same process as Step 4. If the exact item you have is not available in the drop down list, choose the closest option available. For example if you a have a 475mm pipe and the tool only has 450mm pipe then choose this. Don't forget to record the mode of transport and the distance from your supplier to your site for each item. As you complete each category, you should click the 'Mark Complete' box at the top of the page and move onto the category. When you have finished inputting your data, click the Home Page button to return to the front screen. If you have followed the above steps correctly, the Carbon Return you have just entered will now be marked as 'Complete' and highlighted as green. If it is not, check each of the categories again, making sure you have entered the necessary data and ticked each category as complete.
Step 7) Create Export file and Email to Highways England.
Once you have finished inputting your data and returned to the Home Page, you should click the 'Export Carbon Return' button. This will generate an output file which you will need to save and then email to us at the following address: [email protected]
Step 8) Save the Tool.
You will need to save the completed tool (Excel file) on your own computer. Next time you come to enter a new carbon return, you will need to use the same file. Step 9) Next Carbon Return. The next time you come to enter a new carbon return, open up the file you saved last month/quarter. Click on ‘Home Page’ and then click 'Create New Carbon Return', check that the date is correct and click 'Add'. This will now appear in the table along with your other completed carbon returns. Follow the same steps as before to enter your data.
Click the ‘create export file’ to create the file you will need to email to us.

5. What Happens Next?
Summary Report
If you would like to view or print a summary of your carbon return data, you can do this by clicking on the ‘Summary Report’ button at the top of the page. This report contains a summary of your overall emissions compared to a baseline Collation and Analysis of Results Once you have created your export file and sent this to us, your results will be analysed. This analysis will look at how complete and accurate the carbon return is as well as the carbon emissions. Our supply chain’s performance will be monitored and reported upon internally. Ultimately this will inform our decision making processes as we drive towards reducing our carbon emissions. Auditing and Verification of Carbon Returns You may be asked to take part in our verification process. This will be carried out periodically to check the accuracy and validity of the data Highways England collect. This will involve checking the data you are inputting into the tool and assisting you to improve the accuracy of your carbon returns where possible.
Continued collaboration with our supply chain
Our carbon tool has been developed through consultation with our supply chain to ensure it makes the carbon reporting process as easy as possible for you, whilst ensuring we receive the data we need. We would like to thank the members of our supply chain that assisted with this process and welcome continued support from our supply chain community.
