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.
A new report demonstrates that urban policy decisions made before 2020 could determine up to a third of the remaining global carbon budget that is not already ‘locked-in’ by past decisions. Fortunately, C40 and SEI's new analysis shows that a third of the decisions will be made in cities, meaning local leaders in office right now, many of whom have already demonstrated leadership on climate change, can grasp the opportunity to move on to a low-carbon path.
As C40 marks its ten-year anniversary, we are pleased to share a new “10 Years of Results” booklet. We encourage you to read and share these highlights on what C40 has accomplished, as well as our vision for a bright, urban future.
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.
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.
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.
The World is Watching 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're showcasing research and stories that help explain why a global agreement on climate change matters, and why cities are so important to the success of any agreement.
Mayors and local leaders in power today have a major role to play in determining whether or not we have a cost-effective and, therefore, realistic path to a climate safe world.

The World's Leading Philanthropic Organizations are Investing in C40
Jesper Nygard, CEO of Danish philanthropic organization Realdania, on the power of C40 to unite strong and dedicated city leaders in the fight against climate change.
Philanthropy is evolving. More and more, philanthropic investments are data-driven and results-oriented, which means limited resources are flowing towards organizations with the biggest impact. Enter C40. As a network of the world's megacities, C40 is positioned to harness philanthropic investments to improve the lives of over 600 million people -- and as those ideas spread and germinate in cities around the world, they'll impact the majority of the global population.
Mayor of Rio de Janeiro and Chair of C40, Eduardo Paes, attended C40's tenth anniversary event in New York with President Bill Clinton and Michael Bloomberg. Paes' speech reinforced the importance of cities on the road to Paris, and asked attendees to support the Climate Fund, an initiative to help cities finance low-carbon actions.

"People live in cities, not states or nations, so they have to be taken into consideration in the agreements. As mayors, we are closer to people than heads of state. Around the world, mayors have taken the lead and shown the actions through networks like C40." - Mayor Paes, Chair of C40
At the opening panel of the Mayor's Summit, September 9th, from his home city of Rio de Janeiro, the chair of C40 Cities Mayor Eduardo Paes invited Brazilian and world mayors alike to join the Global Compact of Mayors as a way of solidifying their commitment to a more ambitious climate treaty in Paris at COP21. The Compact is the biggest effort among international cities in the fight against climate change.

"Rio Vision 500" is an ambitious new platform that will help direct the future of Rio over the next 50 years and aid the development of the city's Strategic Plan 2017-2020. The process will be 100% collaborative and participatory: Rio's population will be able to send suggestions and vote on the best ideas, and a number of activities are being launched to better engage city residents. Release of the document is slated to coincide with the official celebrations for the city's 450th anniversary. Photo: J. P. Engelbrecht.
"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.

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.
As C40 Chair, Rio de Janeiro Mayor Eduardo Paes is working on behalf of all C40 Mayors to carve a new role for city leaders on the global stage. Above, Mayor Paes meets with China's Premier Li Keqiang to discuss the advancement of climate action in Chinese cities.
