Trees in Cities Challenge

Join the Trees in Cities Challenge, a global movement to restore, protect and maintain trees in urban areas worldwide.

Strategic, tailored and ambitious tree-planting and strengthening capacities for sustainable management of urban forests is a palpable way for local governments to contribute to climate action and the Sustainable Development Goals (SDGs).

The UN Decade on Ecosystem Restoration (2021 – 2030), hopes to inspire large-scale efforts to halt the destruction of natural habitats and restore degraded ecosystems, and is an ideal time for city governments to step in and contribute.

In 2019, the United Nations Economic Commission for Europe (UNECE) launched the Trees in Cities Challenge. This initiative invites local governments worldwide to make a concrete tree-planting pledge that will be implemented within a year and set up objectives for making their cities greener, resilient, and more sustainable.

Those pledging under the Trees in Cities Challenge are invited to become part of a global community of change-makers and offer their residents benefits from the many ecosystem services that trees and forests in and around cities provide. To date over 80 cities and communities around the world have joined the Challenge.
