The 4 Corners Carbon Coalition is a fiscally sponsored non-profit network of local governments advancing community-based carbon dioxide removal (CDR) solutions. Founded in 2022 by Boulder, CO, Flagstaff, AZ, Salt Lake City, UT, and Santa Fe, NM, the coalition launched its inaugural Catalytic Grant Program to support first-of-a-kind CDR projects that deliver durable carbon removal and local environmental and economic benefits.
Through this model—where local partners co-fund and select projects—4C helps communities demonstrate what high-quality, locally anchored carbon removal looks like in practice.
To empower local governments to pioneer the development and implementation of community-anchored carbon dioxide removal solutions at multiple scales.
Local governments emerge as the early actors implementing diverse community-anchored projects that deliver durable carbon removal and environmental benefits.
These projects begin to prove out carbon removal as a beneficial and tangible set of solutions, catalyze cost reductions, and accelerate the utilization of carbon removal approaches nationwide.
The 4 Corners Principles reflect our belief that local governments aren’t just stakeholders in carbon removal — they’re essential drivers of innovation, accountability, and collaboration that can drive action from the ground up.
Local governments — from small towns to major cities — can lead the way in practical, lasting responses to the climate crisis.
They have a vital role in driving fair and effective carbon removal. Instead of waiting for others, we must set the pace and show what real progress looks like.
Every community, big or small, holds unique knowledge and ideas. Local perspectives create opportunities for discovery and innovation that broader governments often miss.
By tapping into this creativity, we can advance and discover real-world carbon removal solutions.
Local governments know best what affects the safety, fairness, and well-being of their communities. Guided by local priorities, they are in the best position to weigh the benefits and risks of carbon removal. This accountability must shape what solutions move forward.
Local governments and communities are strongest when they work together. By sharing knowledge and resources, they can achieve far more than they could alone. Our coalition believes that local collaboration can shape the future of carbon removal on a global scale.
At 4 Corners Carbon Coalition, we know that advancing local carbon removal solutions requires the collaboration of diverse and committed partners. From grassroots advocacy to technical research, field implementation, and critical funding support, our partners strengthen every dimension of our work.
