Cities house half the world’s population but represent almost two-thirds of global energy demand and 70% of carbon emissions from the energy sector. Therefore, our cities have a vital role to play in the transition to a sustainable economy. And across the world, cities are already taking action. Explore which cities have ambitious action to cut emissions and reduce their climate impact.

Cities are leading the transition to a sustainable economy. In 2017 almost 400 cities told CDP about how they are working to reduce greenhouse gas emissions. Explore how cities are working to reduce their climate impact.
