Executive Summary
In September 2021, the Commission for Environmental Cooperation (CEC) launched the Communities for Environmental Justice Network (CEJN) project. The project aims to strengthen the capacity of North American Indigenous, local, disproportionately impacted, marginalized, and/or underserved communities to address environmental justice concerns in the context of climate change. The project supports the creation of a trinational network to facilitate the exchange of community-based expertise, lessons learned, and practical guidance between network participants.
