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.

Catalog of actions to reduce greenhouse gas emissions in cities, as reported by city governments participating in CDP in 2015. 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.

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.

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

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

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.

In 2017, Over 120 cities used the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC) methodology to calculate their emissions. This is a 70% increase on the previous year. Explore cities emissions inventory data to better understand what cities are managing.

Annual city-wide emissions for more than 50 global cities. 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. This dataset provides information on the fuel consumed in a city. The question in the 2017 CDP Questionnaire was as follows: "Please give the total amount of fuel (refers to Scope 1 emissions) that your local government has consumed this year."
