Isometric’s Post

Today, Isometric released the first-ever River Alkalinity Enhancement (RAE) Protocol for public consultation—outlining the requirements for high-quality carbon removal via rivers. Rivers are the primary way carbon moves across the Earth’s continents to the oceans and they release up to 2.5 billion tonnes of carbon dioxide into the atmosphere each year. RAE works by carefully adding finely crushed alkaline rocks—like limestone—to river water. These materials react with carbon dioxide in the river, converting it into stable carbonate and bicarbonate ions. This prevents the carbon dioxide in the river from being released into the atmosphere and allows it to be stored in the oceans for tens of thousands of years. The protocol was developed in line with the Isometric Standard, through collaboration between Isometric’s in-house Science Team and reviewers from Isometric’s independent Science Network of over 300 scientific experts. CarbonRun, a leading RAE supplier, provided extensive feedback during the development of this protocol. We’re inviting comments on the protocol from interested buyers, suppliers and scientists during the 30-day public consultation. Learn how to contribute at the first link in the comments.
