Cascade Climate
Enhanced Rock Weathering
To stabilize our climate, the world must expand its capacity to affordably remove carbon dioxide from the atmosphere alongside deep emissions cuts. Enhanced rock weathering (ERW) is a carbon removal approach grounded in the centuries-old soil management practice of liming. It accelerates natural weathering processes to durably remove CO₂ while benefiting agricultural productivity.
ERW has the potential to become an important pathway for carbon removal with agricultural benefits if key scientific and cost uncertainties are addressed.
Cascade is working to clear the path forward by coordinating inter-comparable field research and developing open-science tools. We're also engaging policymakers, buyers, and standard bodies to ensure the markets and policies shaping ERW's future evolve with science.
Bedrock Initiative
Bedrock Initiative is a coordinated research program generating the agronomic and carbon removal evidence needed to bring enhanced rock weathering into compliance carbon markets and government agricultural programs — where it can deliver value for farmers and the climate at scale.
