Enhanced Rock Weathering

Our initial focus is advancing the progress of enhanced rock weathering (ERW), underpinned by a strong scientific evidence base. We believe that ERW has great potential to play a part in both the world’s long-term durable carbon removal portfolio and sustainable agricultural practice toolkit. We are supporters of accelerated private and public investment in ERW, with an overriding focus on learning and evidence-building to refine our collective understanding of how to optimize the role that ERW could play over a long time horizon. Cascade is leading the following initiatives in ERW:

HIGHLIGHTS

Foundations for CDR Quantification in ERW Deployments

After a year-long process involving over 100 stakeholders, we produced a comprehensive technical reference on the “hows” of rigorous carbon removal quantification in an ERW deployment.

Data sharing system to advance scientific research

To unlock a virtuous cycle of deployment-led learning, we are piloting the first-ever ERW data sharing system, the ERW Data Quarry, that connects researchers to data from commercial ERW deployments.

Coming Soon

ERW MRV cost estimator and database

We built a tool to help inform practitioners of the stacked costs of different analytical measurement choices in an ERW deployment, as well as a database of cost quotes to help practitioners compare costs for leverage.

Policy supporting ERW research and responsible deployment

We advance policies that support ERW innovation, provide early project financing support, and develop rules and regulations for responsible deployment in close coordination with industry and civil society organizations.

Oceans and Rivers

Cascade is expanding our work to help accelerate progress across the broader family of durable, natural system carbon removal pathways. We will have a particular, though not exclusive, focus on ocean and river alkalinity enhancement pathways that are the most immediately related ‘sibling’ pathways of ERW.

Just as Cascade did in the early days of its work on ERW, we are beginning work in new areas by learning from—and building trusted relationships with—those who have been working in these domains for years. The particular bottlenecks facing durable ocean and river pathways have some commonality with, but also some sharp differences from, those in ERW. Cascade will help strengthen shared learnings amongst researchers and practitioners, and accelerate the pace of progress across these alkalinity enhancement pathways.
