We Put People & Planet First

Working together to build equitable and resilient solutions to the climate crisis.

About Cambium Carbon

Cambium Carbon is a people-centric, forward-focused company transforming the way communities and organizations approach the climate crisis. We believe in actions that drive results, and we are unapologetically committed to sharing the stories of our results with the world. Our stories are about impact and we believe impact inspires others to action.

We are a platform that enables circular economies through Carbon-Smart material reuse, by unlocking the power of local suppliers. We save fallen trees from landfill and decomposition, transforming them into valuable products with place-based impact. Our Carbon Smart Wood is locally sourced, locally salvaged, and reinvests in local tree planting. This circular economy model creates new green jobs and funding to support urban canopy restoration in the communities that need it most.
