The C40 Cities Bloomberg Philanthropies Awards are granted annually in five categories and provide global recognition for cities that are demonstrating climate action leadership.


Throughout the world, mayors deliver important, impactful, and innovative policies and programmes that reduce carbon pollution and improve resilience. Since 2013, C40 has recognised more than 40 of the world’s boldest projects, highlighting the critical role cities play as a leading force for climate action.


Given the urgency of climate action in the US, this year's Awards will have a special focus on the leadership of US cities on the global stage. Each category of the C40 Cities Bloomberg Awards 2017 will have an international winner and a US winner. 




The Awards recognise cities that have implemented outstanding projects, programmes, policies and practices to combat climate change and reduce climate risks in the fields of 5 categories:

The Cities4Energy category features excellence in building energy efficiency and clean energy.


The Cities4Mobility category features excellence in sustainable transportation.  


The Cities4ZeroWaste category features excellence in reducing waste.


The Cities4Action category features the most ambitious city-wide action plans. 


The Cities4Tomorrow category features the most ambitious adaptation plans and programmes.
