Seventy cities competed for this year’s prestigious awards. The awards celebrate pioneering climate projects led by cities around the world, recognising mayors and encouraging friendly competition between cities keen to demonstrate their successful climate actions and raise global ambition.

Cities are leading the way when it comes to tackling the climate emergency. These cities represent some of the best projects from around the world and their commitment to local communities and the planet is impressive. The focus on immediate climate action illustrates the power of cities to be doers, not delayers, setting a new level of ambition that I hope will inspire leaders around the world to invest in a greener future.”

Michael R. Bloomberg, C40 Board President, UN Special Envoy on Climate Ambition and Solutions, 108th Mayor of New York City and Founder of Bloomberg Philanthropies, said: “Across the world, mayors and cities are increasingly uniting to share strategies, set ambitious goals and deliver much-needed results in the fight against climate change.

C40 Executive Director Mark Watts said: “I am thrilled to congratulate the winners of the C40 Cities Bloomberg Philanthropies Awards. The winning projects are excellent examples of cities making a strong impact on their communities. A healthier, cleaner future must be every mayor’s priority. When mayors invest in the green recovery, they create jobs and just, thriving communities for all. This year’s winners are climate leaders and we are proud to highlight their hard work at the C40 World Mayors Summit.”

Supriya Sahu, Principal Secretary for the Department of Environment, Climate Change & Forests in the government of Tamil Nadu, India, and one of eight awards jurors, said: “On behalf of the jury, I am thrilled to congratulate this year’s C40 Cities Bloomberg Philanthropies Awards winners on their impressive climate projects and leadership.
