🗞️ Driving the news: The first independently verified carbon removal credits for Enhanced Rock Weathering (ERW) were recently issued, purchased by Dutch company Adyen and verified by Isometric
ERW involves spreading crushed rock on farmland, which sequesters CO2 while improving soil health and crop productivity
The sector is gaining traction, with companies like Google and startup Terradot investing heavily

🔭 The context: ERW relies on pulverized rock to chemically bind with CO2, providing a cost-effective and long-lasting carbon removal method
In 2024, ERW accounted for 65% of all contracted carbon removal volume, totaling 290,000 tons for major deals with Google and others
The industry has faced challenges due to limited project verification but is now addressing this gap

🌍 Why it matters for the planet: ERW not only removes carbon but also benefits farmers by enhancing soil health and boosting crop yields
It provides a scalable and low-cost method to combat climate change, with sequestration lasting thousands of years
As climate pressures mount, ERW could be a cornerstone of global carbon removal strategies.

⏭️ What's next: Expect rapid growth in ERW adoption as more companies purchase credits and developers scale operations
By 2027, InPlanet plans to remove one megaton of CO2, while ERW credits are projected to reach $200 per ton by 2030
Advances in verification and funding are likely to sustain the sector's momentum

💬 One quote: "The verified credits are 'a huge moment for carbon removal,' key for 'inviting more capital in,' and for more buyers to start buying credits." – Eamon Jubbawy, CEO of Isometric

📈 One stat: Enhanced Rock Weathering projects currently represent just 2% of carbon removal credits, totaling 560,000 tons purchased
