This dataset contains 2021 data on cities' emissions reduction actions, as reported by cities through the CDP-ICLEI Unified Reporting System in response to question 5.4 in the 2021 CDP Cities questionnaire. View questionnaire guidance at https://www.cdp.net/en/guidance/guidance-for-cities. Please contact cities@cdp.net if you have any questions about the data contained in this dataset.

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’.

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.

Housing 50% of the world’s population, cities are particularly vulnerable to climate change impacts. In 2017, some 380 cities disclosed their adaptation actions through CDP. Explore how these cities are building resilience to environmental impacts.

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.

The dataset contains all public data on cities' adaptation actions as reported by cities in 2018 and 2019.

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 2013. 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.
