Documenting the ambitious, science-based climate actions cities are taking

To assess how cities have delivered on their accelerator pledges, C40 Cities conducted a thorough reporting process in 2021. This process focused on the five longest-running C40 accelerators, documenting the impactful actions cities are committing to and accomplishing globally. Cities were also encouraged to report on their Equity Pledge commitments through this process.

Signatory cities have already delivered more than 270 ambitious actions and are on track to accelerate this, with over 900 additional actions in progress or planned to be completed by 2030. Access the reports below to learn more.
