This Week in CDR - Week 24, 2025

We are back with another edition of This Week in CDR, a weekly round-up of the top news, developments, and market updates from the world of durable carbon removal.

This week saw some key developments in durable CDR, including an offtake agreement between Waldegg Equity Partners and Phlair, a community-driven CDR purchasing initiative by 4 Corners Carbon Coalition, along with the launch of a whitepaper on biochar credits by CEEZER.

We recently released an update to our durable CDR method classification system to improve clarity, reflect current industry practices, and enhance how we organize, track, and report carbon removal activity. The method update will be implemented by June 20, and we call upon all suppliers in the ecosystem to verify their methods with us. Read the blog post to learn more.

CDR.fyi Updates and Research

• CDR.fyi Durable CDR Methods Update | June 2025

We recently released a blog post outlining updates to how we classify durable CDR methods across the CDR.fyi platform. These changes aim to better reflect how projects operate today and improve how we track, analyze, and report activity in the market.

The updated framework clarifies terminology, consolidates overlapping categories, and aligns each method with how carbon is captured and sequestered—enhancing consistency across datasets, reporting, and industry communication. The method update will be implemented by June 20, and we call upon all suppliers in the ecosystem to verify their methods with us. For any feedback or questions, reach out to us at team@cdr.fyi.
