A twofold global challenge
• Overuse of the global
commons
@MCC_Berlin
• Underprovision of public
infrastructure

What about the renaissance of coal?

There is some progress, especially in China

Does the renaissance of coal come to a standstill?

The 2°C budget does not leave any leeway
• Cheap and abundant coal is the driver of a „re-carbonisation“ of the energy
system in some parts of the world
7*All budgets are are subject to considerable uncertainty, see Edenhofer et al. (2016)

Carbon pricing along common
but differentiated responsibilities
• Carbon pricing (with taxes or emission trading systems) is essential
because of the oversupply of fossil fuels.

Carbon Pricing in G20 Countries

Carbon pricing revenues are sufficient
to finance universal access to infrastructure
11
Except for roads
where Africa’s &
Latin America’s
costs still
partially exceed
revenues

Carbon pricing and access to infrastructure –Example of Nigeria
12
• Expansion of infrastructure can be designed to benefit low-income earners
• Example Nigeria: low-income earners so far severely disadvantaged
concerning access to infrastructure

Carbon pricing and tax reduction –
Example of British Columbia
• Introduction of a carbon tax in 2008:
• Significant decrease of CO2-emissions
• Continuous public support
• Use of revenues: reduction of corporation and
income tax

The future of global climate policy: Combining climate
protection and carbon pricing with the SDG agenda
• Re-orienting investment strategies to exploit the significant
opportunities of low-carbon, climate-resilient infrastructure
• Importance of Green Finance: Transforming finance to be
an enabler and driver of change
• Phasing out fossil fuel subsidies
• Price carbon broadly while increasing access to
sustainable infrastructure to ensure a just transition
towards a low-carbon economy

Climate policy in the era of Trump• Donald Trump acts against the market forces and many
governors: • Coal in the U.S. cannot compete with gas
• Call for carbon pricing by many U.S. companies, e.g. Exxon
• „We are still in“ coalition in US including several Federal States
• It is in their own interest that China and Germany/EU continue with their efforts to combat climate change
• Possible areas for stronger cooperation:• Debate on Green Finance, currently led by China
• Exchanging experiences about emissions trading
• Sustainable infrastructure
