In 2023, the U.S. EPA, in partnership with the U.S. DOE Office of Clean Energy Demonstrations, designated two types of TCTACs: national and regional. Each has an important role to play in the work to support communities working towards environmental justice. Currently, there are 16 hubs with over 144 partners across the United States, with two more hubs expected in May 2024.


The national TCTACs are the Institute for Sustainable Communities (ISC), National Indian Health Board (NIHB), and the International City/County Management Association (ICMA). National TCTACs use their extensive networks in nonprofits, tribes, and local governments, respectively, to connect environmental justice organizations with even more opportunities. They plan events and trainings, and find and create resources — like this website — that bring environmental justice communities together and elevate their stories.

How Do EJ TCTACs Work?

The regional TCTACs are the main points of contact for eligible entities looking to get support. If you are in a community with environmental justice concerns, your regional TCTAC can help you navigate federal programs, encourage community engagement, and provide other tools to make your environmental justice projects successful.
