This dataset contains data on total city-wide emissions as reported by cities in 2021. To view all responses by cities to questions on emissions in 2021, including breakdowns by sector and scope, go to https://data.cdp.net/Governance/2021-Cities-Emissions-and-Mitigation/aic4-a5fb. The questions covered are 4.6a to 4.6b.

Access cities questionnaire guidance at https://www.cdp.net/en/guidance/guidance-for-cities.

Please contact cities@cdp.net if you have any questions.

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’.

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, 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 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.

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.

Annual city-wide emissions for more than 100 global cities. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

Annual city-wide emissions for more than 149 global cities. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

Annual city-wide emissions for more than 30 global cities. Includes information about how cities measured emissions (primary protocol).

Emissions reduction targets for all reporting cities in 2015. Includes baseline emissions, baseline year, percentage reduction target, and other details. Some cities report multiple targets.

This dataset outlines the city-wide emissions including a breakdown of the gases as well as the overall changes in the emissions reported. Please contact cities@cdp.net for further information on the breakdown of emissions under this protocol and on how to use this data.
