Cities program

Through CDP, cities around the world are measuring, monitoring and managing their impact on the environment. Over the past five years, CDP has worked with 207 cities to manage over 1 billion metric tonnes of greenhouse gas emissions. CDP’s cities program demonstrates that cities are better managing their risk and increasing resiliency through more than 2,000 activities to mitigate and adapt to climate change.

  • City–to-city learning


    Singapore's success and prosperity depends on being able to overcome the challenges of climate change and to grasp the opportunities it presents. Our participation in CDP gave us a platform and opportunity to learn and share best practices across cities in climate change mitigation, adaptation and resilience.

    CDP reporting provides an understandable structure of sustainability indicators with regards to emissions and climate change resilience activities.

Data measurement plays a critical role in sound management, but for too long has been largely missing from the fight against climate change. Together with C40, CDP is changing that and helping cities around the world to reduce their carbon footprints. Given Bloomberg Philanthropies' own commitment to using data to measure and manage problems, and to the issue of climate change, this partnership is a perfect fit.
