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.

In 2015, 120 global cities publicly disclosed their annual city-wide emissions. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

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.

In 2016, 189 global cities publicly disclosed their annual city-wide emissions. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

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.

When using the inventory data for aggregation, comparison and trend analysis, please note that the inventory data is based on non-verified self-reported city inputs. The reported inventory may not include all emission sources within the city boundary.

This data is collected through the CDP-ICLEI Unified Reporting System. When using this data, please cite both organisations using the following wording: ‘This data was collected in partnership by CDP and ICLEI - Local Governments for Sustainability’.
