Four Corners Office for Resource Efficiency

Empowering Southwest Colorado with Climate Solutions For a Sustainable Future

WHO WE ARE

The Four Corners Office for Resource Efficiency (4CORE) is a 501(c)(3) non-profit organization that provides climate solutions through boots-on-the-ground energy efficiency, clean transportation, and water conservation projects.

4CORE provides climate solutions to help people, especially low-income, underserved, and underrepresented people in Southwest Colorado, achieve immediate energy and cost savings.

We champion beneficial electrification and renewable energy installations, promote clean transportation through electric vehicle and eBike adoption, and support local businesses with our Green Business Certification Program. 

Our programs deliver energy and cost savings, especially for our lower-income residents, ensuring a sustainable and equitable future for all.

4CORE's mission is to serve Southwest Colorado by promoting resource conservation, energy efficiency, and renewable energy. We achieve this through education and programs that not only strengthen our local economy but also foster a healthy, sustainable environment.
