CITIES GLOBALLY UNITED / 17

Promise registry

What cities have said they will do, by when, and what we can show about it. A plan is not a result.

How to read an entry

Each entry quotes a commitment, plan or date published by a city or an institution, with the year, the source and how we verified it. The status says only whether the target year is still ahead, has passed, or is a recorded date. We do not score or rank cities.
