C40 Cities Climate Leadership Group (2005; Rio de Janeiro; ~170 staff; www.c40.org)
A global network of large megacities taking action to address climate change by developing and implementing policies and programs that generate measurable reductions in both greenhouse gas emissions and climate risks. The focus on cities is based on their role of innovation hubs. Over 90 affiliated cities around the world make up over 25% of the GDP and 1 in 12 people worldwide. C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban citizens.
Clinton Climate Initiative (CCI) is a delivery partner. Funded within others by Bloomberg Philanthropies, Children’s Investment Fund Foundation, and Realdania.
- Annual reports
- A blog, media, and events
- An interactive database with statistics and analysis of participating cities
- A research library with reports, papers and articles that analyze key trends, identify opportunities for further action across the global C40 network, and prioritizes initiative areas with the greatest potential for action and impact.
- Climate Opportunity: More Jobs; Better Health (2018, 63p.) – As cities around the world accelerate efforts to meet their commitments to the Paris Agreement, new research from C40 Cities, The Global Covenant of Mayors for Climate & Energy and the New Climate Institute, shows that ambitious urban climate policies can vastly reduce carbon emissions globally as well as effectively deliver enormous economic and public health benefits for cities.
- Summary for Urban Policymakers: What the IPCC Special Report on Global Warming of 1.5°C Means for Cities (2018, 30p.) – Based on the premise that “climate science must be accessible to urban policymakers, because without them, there will be no limiting global warming to 1.5°C. The effects of a city’s actions are not limited to its own borders or region, and lessons learned in some cities and urban areas can serve as inspiration and resources for solutions in other urban areas.”
- Focused acceleration: A strategic approach to climate action in cities to 2030 (2017, 72p.) – “This Report identifies 12 opportunities that have the greatest potential in most global cities to curb emissions and put cities on a 1.5°C pathway through 2030.”
