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 100 global cities. Includes information about how cities measured emissions (primary protocol), as well as why emissions rose/fell since prior reporting period.

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.

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.

State and regional government climate data is fundamental to delivering the Paris Agreement. Using the data that states and regions disclosed to CDP, we estimate that those that disclosed both a region-wide GHG emissions reduction target and a GHG inventory, are on course to meet the objectives of the Paris Agreement by 2020.
We incorporated the 2017 International Energy Agency scenarios to explore how collective emissions of states and regions change over time. This shows that disclosing states and regions are on average setting more ambitious targets than those set by their national counterparts. This demonstrates that present 2020 targets are sufficient to put states and regions on a trajectory for a 2 degree Celsius world. However, their long-term targets while more ambitious than their national counterparts, are not sufficient to keep the world below a 2 degree rise after 2020.

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.

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.

Emissions reduction targets for all reporting cities in 2014. Includes baseline emissions, baseline year, percentage reduction target, and other details. Some cities report multiple targets.
