In a significant step towards reducing its carbon footprint, Microsoft (NASDAQ:MSFT) has entered into a new agreement with climate tech startup InPlanet. The arrangement involves purchasing more than 28,500 tonnes of CO2 removal through Enhanced Rock Weathering (ERW) projects in Brazil between 2026 and 2028. This collaboration is aligned with Microsoft’s ongoing initiatives to decrease its environmental impact and to contribute actively to global sustainability efforts.
Microsoft has frequently collaborated with entities focused on carbon removal, consistently supporting large-scale projects to meet their carbon-negative target by 2030. The company has shown consistent effort in acquiring carbon credits through numerous agreements with startups engaged in ERW. Microsoft’s extensive purchasing history demonstrates their commitment to effective carbon management and corporate responsibility.
How does Enhanced Rock Weathering work?
ERW is a process that utilizes finely crushed silicate rock, applied to tropical soils, which accelerates natural weathering to remove CO2 durably. InPlanet has pioneered ERW as a scientifically validated method for carbon dioxide removal, addressing climate and agricultural challenges. This approach also facilitates improved soil fertility and increased crop productivity, providing tangible benefits to local farming communities.
What are the main features of the agreement with Microsoft?
The credit issuance follows Isometric’s Enhanced Weathering Protocol and will be transparently recorded on the Isometric Registry. Additionally, anonymized project data will be available through Cascade Climate’s Data Quarry, supporting ongoing transparency and scientific examination across the industry. InPlanet’s monitoring of soil chemistry and water systems plays an essential role in verifying that CO2 removal claims are meticulously documented.
The agreement further broadens Microsoft’s portfolio of carbon removal initiatives. Their position as the largest corporate buyer of carbon removal credits is solidified with cumulative purchases reported at over 34.5 million tonnes. Microsoft’s proactive approach provides a model for other corporations aiming to offset their carbon emissions while supporting innovation in climate technology.
Felix Harteneck, Founder & CEO of InPlanet, expressed enthusiasm for the collaboration:
“As part of this agreement with Microsoft, we can deepen our scientific research and further validate Enhanced Rock Weathering under real-world conditions…”
Phillip Goodman, Director, Carbon Removal Portfolio at Microsoft, highlighted the ongoing benefits of InPlanet’s work:
“InPlanet’s commitment to measurement and monitoring bolster the integrity of their enhanced rock weathering carbon removal credits…”
This initiative emphasizes how corporate partnerships with climate startups can expedite progress toward carbon reduction goals. With ERW as a viable method for carbon removal, companies have an alternative solution that also delivers benefits like improved agricultural productivity. Understanding the intricacies of these methodologies aids corporations and governments in forming effective strategies to combat the climate crisis. Disseminating insights from these projects can act as a catalyst for broader adoption and improvement of carbon removal strategies.
