The company’s process applies finely crushed silicate rock to tropical soils, accelerating the natural weathering process that permanently sequester CO2, in addition to providing benefits to local farmers including improved soil fertility, increased crop productivity, and reduced need for agricultural inputs. InPlanet operates the largest ERW program in Brazil to date, measured by total farmland treated, at more than 12,000 hectares.Felix Harteneck, Founder &amp; CEO of InPlanet, said:<blockquote>“As part of this agreement with Microsoft, we can deepen our scientific research and further validate Enhanced Rock Weathering under real-world conditions. Our team is monitoring every aspect, from soil chemistry to local water systems, to ensure each tonne of CO₂ is rigorously accounted for. The insights we gain from these deployments will improve our measurement and verification methods, setting an even higher bar for transparency in carbon removal.”</blockquote>As part of the new agreement, all credits will be issued under Isometric’s Enhanced Weathering Protocol and publicly listed on the Isometric Registry, with anonymized project data also to be shared through Cascade Climate’s ERW Data Quarry to support transparency and industry-wide scientific research.The deal marks the latest in a growing series of carbon removal agreements by Microsoft, including several ERW-based agreements, forming part of the tech giant’s ambition to become carbon negative by 2030. Microsoft is by far the largest corporate buyer of carbon removal credits globally, with purchases exceeding 34.5 million tonnes, according to carbon dioxide removals (CDRs) platform CDR.fyi.Phillip Goodman, Director, Carbon Removal Portfolio at Microsoft, said:<blockquote>“InPlanet’s commitment to measurement and monitoring bolster the integrity of their enhanced rock weathering carbon removal credits, which will contribute to Microsoft’s goal to be carbon negative by 2030. Their project illustrates how applying silicate rock to soils can offer benefits for farmers by improving soil health and supporting productivity. Enhanced rock weathering is a promising pathway to high-impact carbon removal, and we are encouraged by its potential to contribute to durable, positive climate outcomes.”</blockquote><hr/>More By This Author:Google Signs Ocean-Based Carbon Removal Deal With Ebb Carbon Meta Signs 2.5 GW Of US Clean Energy Deals With NextEra AT&amp;T Commits To Drop DEI Programs And Goals </div></div>
