Cities

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 620 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.

CDP analyzes submitted data so cities can show how their actions are safeguarding citizens and benefiting the economy.
Disclosure helps a city demonstrate how it is acting on climate change and provides data to improve these actions year-on-year.
By sharing a platform used by thousands of businesses, cities can increase collaboration with the private sector, realize their full potential for climate-resilient futures and ensure long-term prosperity.
Cities that are acting and disclosing actions on climate change are better placed to attract investment.

    Getting the most from your climate disclosure with WWF’s One Planet City Challenge and CDP

    Are you curious how your city’s goals and action stack up to the latest climate science? This year, as part of your CDP disclosure, you can enter World Wildlife Fund’s One Planet City Challenge (OPCC) and receive actionable feedback about how your city measures up to a 1.5 degree reduction pathway. You can also see you work side-by-side with a diverse global cohort of cities for insight exploring new ideas.

    Now in its eighth year, the OPCC is an initiative organized by WWF to guide cities towards the most effective, evidence-based climate action, as well as recognize outstanding leadership.

    WWF, together with C40 and Arup have developed a new assessment methodology expanding on C40’s Deadline 2020 framework allowing any city to better measure their action in-line with the Paris Agreement and IPCC 1.5 report. Cities wishing to participate in the One Planet City Challenge (OPCC) are invited to report their climate ambitions through CDP’s reporting platform.

    Watch this webinar from WWF and CDP on the OPCC and more benefits to disclosure this year.
