Cities are responsible for 75% of global greenhouse gas emissions. The transition to a sustainable economy will be won or lost in our cities. Explore how cities across the globe are working to measure their city-wide emissions, a vital first step towards taking ambitious climate action.

In 2015, 120 cities publicly reported annual city-wide emissions. This map includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

Responsible for 75% of global greenhouse gas emissions, 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.

Catalog of actions to reduce greenhouse gas emissions in cities, as reported by city governments participating in CDP in 2014. Activities are tagged by sector and cities provide detailed descriptions of each activity. Some cities also provide estimates of the total anticipated lifetime emissions that will be reduced from each activity.
