C40 is a network of the world’s megacities committed to addressing climate change.
Acting both locally and collaboratively, C40 cities are having a meaningful global impact in reducing both greenhouse gas emissions and climate risks. C40 brings together a unique set of assets and creates a shared sense of purpose. C40 offers cities an effective forum where they can collaborate, share knowledge and drive meaningful, measurable and sustainable action on climate change.
Rio de Janeiro recently became the world’s first city to comply with the Compact of Mayors, an agreement by city networks to undertake a transparent and supportive approach to reduce city-level emissions, reduce vulnerability and enhance resilience to climate change, in a consistent and complimentary manner to national level climate protection efforts.
Mayors are delivering important, innovative policies and programmes that reduce emissions and improve sustainability. The C40 Cities Awards were created to recognize those successes, catalyze ambition, and share lessons with cities around the world. The 2015 Awards will take place in Paris to coincide with the 21st Conference of Parties (COP21).
By partnering with media outlets like National Geographic and CNN, The Guardian and Xinhua, C40 is helping to bring attention to the work of its member cities. A new partnership with Clear Channel Outdoor will ensure that this message reaches its primary audience -- urban citizens -- by showcasing C40 on digital billboards across our member cities.
C40 networks facilitate dialogue, cooperation, and information exchange amongst city officials. The result is that cities' climate actions to reduce GHGs and climate risks are bolder, more impactful, and implemented faster with less resources than if they were to go it alone. No other organisation connects city staff across 50+ countries, 20 time zones and 26 languages to accelerate local action with major global impact.
"The evidence is clear that [C40's] networking strategy is working," says C40 Board President and UN Special Envoy for Cities & Climate Change Michael R. Bloomberg in the most recent issue of Foreign Affairs magazine, where he writes about city climate action as a catalyst for public health and economic growth.
C40 and Arup have released a new report, Powering Climate Action: Cities as Global Changemakers, which demonstrates that cities have the tools to deliver meaningful action, and that cities using a collaborative approach to governance deliver far more action. Powering Climate Action is a comprehensive survey of the powers and governance approaches used by cities to deliver climate action built on 123,078 data points reported directly by 66 C40 cities.
As COP 21 approaches, the world's media has increased its focus on cities -- and for good reason. Cities are at the center of climate action, having enacted more than 8,000 measures, policies, and programmes to address climate issues since C40 started measuring.
As a primer to the pivotal meeting in Paris, we've gathered stories that help explain why a global agreement on climate change matters, and why cities are so important to the success of any agreement.

"Part of my work with the United Nations, where I am the Secretary-General’s Special Envoy for Cities and Climate Change, involves encouraging national governments to look to cities as their partners on climate change. China understands the important role cities play in reducing emissions, and there is much that city leaders can learn from one another. It is encouraging that several Chinese cities have joined the C40 Cities Climate Leadership Group, which helps cities exchange innovative ideas." Read more...
More then 20 C40 Mayors met recently with other world leaders to share best practices on climate change.
Partners are investing in C40 because #CitiesAreKey
Since 2009, Arup has worked with C40 to develop strategic pieces of research that have been central to progressing our understanding of how cities contribute to climate change mitigation and adaptation.
Arup and C40 Cities Climate Leadership Group (C40) have announced the formation of a collaborative global partnership. Over the next three years, Arup will invest $1 million into research through the partnership with C40, which will help to improve the measurement, management and strategic planning of climate action in cities.
This video provides snapshots of urban landscapes around the world, and highlights the important work both Arup and C40 are doing to help cities accelerate action on global climate change.
"Cities are our “Common Home” and we must work together to make them safe, fair and sustainable. As leaders of our communities, we believe in cities as a force for good. By embracing their potential, we can address many of today’s most urgent challenges – including threats like climate change and modern slavery," said Rodrigo Rosa, Special Adviser to the C40 Chair, at the Pope's climate change conference in Vatican City.

"If empowered further, cities can do so much more in the fight against climate change. We hope cities, their partners and the wider international community will receive this report as a firm call to action."
The Steering Committee has voted unanimously to extend current chair and Rio de Janeiro Mayor Eduardo Paes’ tenure through 2016. "It has been a great privilege to help lead the global conversation on cities and climate change, and create the cities of the future," Mayor Paes said.
In partnership with the UNFCCC, Mayor Paes has authored an editorial in the Brazilian newspaper O Globo discussing Pope Francis' Encyclical, supporting the Vatican's move to focus on climate change, on behalf of all C40 cities.
