Cascade ClimateWe 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 …

Introducing the Core Principles on Quantifying Net Carbon Removal Via Enhanced Rock Weathering
In November, 93 leaders in enhanced rock weathering (ERW)–including scientists, suppliers, buyers, credit issuers, civil society and more–publicly signed on to a set of Core Principles on the quantification of net carbon removal via ERW. The Core Principles represent an ERW community-wide view on rigorous quantification and set a shared …

Launching the Community Enhanced Rock Weathering Quantification Standard Process
2023 and 2024 represent a critical time in the development of agricultural enhanced rock weathering (ERW) as an industry and pathway. Increasingly large-scale field trials and deployments are beginning globally, major buyers are signing the first ERW offtake agreements, and new suppliers are entering the market at a rapid clip. …
