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.

CDP is working in partnership with The Climate Group to provide the world’s first global platform for states and regions to measure, manage and disclose their greenhouse gas emissions. CDP and The Climate Group are united in their firm belief on the vital role that state and regional governments play in driving climate action and delivering sustainable economies that avoid dangerous climate change and leads to a net-zero emissions world. Use this data to explore GHG emissions from state and regional governments.

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.
