In 2016, over 3,000 city-wide mitigation actions were disclosed. Cities are taking action to reduce greenhouse gas emissions in cities. 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.

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’.

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.

CDP’s new infographic report ‘Who’s tackling urban water challenges’, produced in partnership with AECOM, the global infrastructure firm, and funded by Bloomberg Philanthropies, shows the first and most comprehensive dataset of global water action by cities and companies produced to date. Using information gathered from 569 cities and 1,432 companies, each reporting their water management activity, it illustrates how global cities and companies are responding to the escalating challenge of climate change and urban population growth.

Explore how cities and companies are acting on water, the CDP infographic report ‘Who’s in charge of Water Governance’, with case studies and full data is available at www.cdp.net/cities.

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.

Dataset provided by members of the RegionsAdapt Initiative.

It contains 39 regions that reported publicly in 2018.

Cities are leading the transition to a sustainable economy. In 2017 over 350 cities told CDP that they are working to reduce emissions in their own city operations. Cities are leading my example and changing the way that they operate.

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.

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.
