Our cities are changing. More than ever, cities around the world are leading the way to building a sustainable economy. But we need to move even faster. Explore our Open Data Portal for more on how cities across the globe are taking environmental action.

CDP provides the global platform for cities to measure, manage and disclose their environmental data. We work with over 500 cities measuring and disclosing environmental data each year to manage emissions, build resilience, protect themselves from climate impacts and create better places for people to live and work. These cities are disclosing over 8,000 urban sustainability actions, demonstrating their commitment to building a sustainable economy and tackling climate change. We are nearing a tipping point in mainstreaming environmental action, and cities are at the heart of this transition.
