Cascade ClimateERW Metal Accumulation Calculator
As enhanced rock weathering gains momentum as a promising carbon removal approach, we need to ensure it remains environmentally sound. The ERW-MAC helps practitioners understand potential metal accumulation risks in soils from ERW deployments using intentionally conservative assumptions.

We can and must set rigorous MRV methodologies for enhanced rock weathering now.
A question we often hear from the ERW community is: knowing the complexity, heterogeneity, and spatiotemporal scale of quantifying CDR in an ERW deployment, is it possible to develop rigorous methodologies that guide deployments today?

Foundations for a Healthy ERW Market Cycle
Last week marked a big moment in the short history of durable open-system carbon removal. The announcement of Frontier’s $57M offtake agreement to buy ~150,000 removed tons from Lithos, an enhanced rock weathering (ERW) supplier, is the world’s first truly large-scale, multi-year purchase of durable carbon removal via an open-system …
