This Week in CDR - Week 35, 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, as Frontier and Planetary signed an offtake agreement for 115,211 tonnes of CDR, while Altitude purchased 50,000 tonnes from Greenglow, and the EU published 3 reports exploring an EU-wide purchasing programme for durable CDR.
In July, we released the 2025 Q2 Durable CDR Market Update, in which we analyze and uncover some key trends from the durable carbon removal market.
In addition to the blog post, a more extensive report exclusive to our Data Partners and Platform Subscribers is available through the CDR.fyi Portal. Sign up for a Portal account here.
