💎 Enhanced Rock Weathering: The Diamond in the basalt rock 💎

📈 ERW remains one of the most scalable, cost-effective, and co-beneficial CDR solutions available. But don’t just take my word for it. 

🌍 The IPCC has recognised ERW as a high-potential CDR approach, estimating its global removal capacity at 2–4 GtCO₂ per year by 2050. Within Europe, studies suggest its five largest countries alone could remove up to 200 Mt of CO₂ annually - almost half of all its expected residual emissions.

🚜 In addition to its climate potential, it has tremendous co-benefits for farmers: ERW can serve as a free replacement for aglime and requires minimal changes to farming operations. 

👀 As a result, its potential is being recognised in the market: ERW is already achieving pricing of around $300 per tonne with deals from Frontier and Google. In December 2024, the largest ERW deal in history was closed—Terradot secured a 200k tonne contract worth $58 million.

👎 Yet, despite all this momentum, its often overlooked in policy discussions. For example, in Europe - unlike DACCS, BECCS, and BCR - it has not been prioritised in the first round of CRCF methodologies and is eligible for only a small fraction of funding opportunities.

🏛️ Today the amazing team at Cascade Climate are releasing their white paper, Farming with Rocks: Policy Priorities for Enhanced Rock Weathering. 

📑 In it, they outline how to ensure ERW receives the recognition and support it deserves. Expect targeted explainers and blogs breaking down these recommendations. 

🖇️ Make sure to give it a read: https://lnkd.in/dsvnytQ6

👏 Big shout out to the Cascade team, Dai Ellis, Vilas Rao, Hara Wang, Brad Rochlin, and Rachel S.. 

✅ And if you are in team ERW, make sure to give Enhanced Weathering Alliance (EWA) a follow, the global association standing up for the sector as a whole.

⁉️ What is your take: do you agree with the potential of ERW?
