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.

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.

The dataset contains 2021 data on cities' water security risks, reported by cities through the CDP-ICLEI Unified Reporting System in response to question 14.2a ("Please identify the risks to your city’s water security as well as the timescale and level of risk.") in the 2021 Cities questionnaire.
