C40 Membership Grows to 75 Global Cities

C40 is pleased to welcome Amman, Durban, Jaipur, Quito, and Salvador to its global network of cities committed to tackling climate change and increasing urban resilience. These five cities bring C40’s overall membership to 75 cities, a key milestone in the organisation’s expansion efforts and a testament to the success of city-to-city collaboration on climate change.

“By taking bold action and collaborating, mayors around the world are driving the climate change agenda on a global scale toward lower emissions and greater resilience,” said C40 Chair, Rio de Janeiro Mayor Eduardo Paes. “These five cities truly represent the diversity and ethos of the C40 – they span three continents but are united in their desire to increase the health, well-being and economic opportunities of urban citizens.”

“The C40 network keeps growing because more and more cities are finding opportunities to confront climate change in ways that improve people’s lives today,” said U.N. Special Envoy for Cities and Climate Change and President of the C40 Board Michael R. Bloomberg. “For the U.N. climate treaty negotiations this December to be successful, nations will have to commit to doing more and acting faster to shrink their carbon footprints – and cities, including the five new members of C40, are helping point the way forward.”

The five new member cities represent an estimated 21 million people and have each demonstrated strong leadership in climate action in their regions.

The C40 Cities Climate Leadership Group (C40) is a network of large and engaged cities from around the world committed to implementing meaningful and sustainable climate-related actions locally that will help address climate change globally. Recognizing that cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions, our organization’s global field staff works with city governments, supported by our technical experts across a range of program areas to reduce carbon emissions and increase energy efficiency in large cities across the world. The current chair of the C40 is Rio de Janeiro Mayor Eduardo Paes, and 108th Mayor of New York City Michael R. Bloomberg is President of the Board. The Steering Committee includes: Berlin, Buenos Aires, Copenhagen, Hong Kong, Houston, Jakarta, Johannesburg, London, Los Angeles, Rio de Janeiro, Seoul and Tokyo.
