Independent Assessment of climate goals - WWF's OPCC Assessment Framework (Event organised by a Mission Project)

Urban leadership for a thriving planet

Cities have the power to drive transformative change, but navigating the path toward a climate-resilient future can be complex. WWF created the One Planet City Challenge (OPCC) in 2011 to facilitate and accelerate this process.

Since then, the program has grown to be the largest and most impactful initiative of its kind. Nearly 900 cities from 70 countries have participated, creating a critical mass of ambitious local governments actively advancing the urban sustainability agenda.

To join, sign up to the CDP-ICLEI Track. Inside of the platform, tick off the box to join the OPCC.
