Microsoft (NASDAQ:MSFT) has announced a partnership with Indian climate tech firm Alt Carbon to purchase carbon removal credits. The deal, totalling nearly 37,000 tons of CO2 credits from Alt Carbon’s enhanced rock weathering project, is aimed at curbing emissions on a large scale. Achieving these carbon removal goals could have long-term benefits on the carbon credit market, making it more accessible and efficient.
In April, Microsoft indicated a pause in its carbon removal purchases, which raised questions about its commitment to carbon credit funding. This new deal signifies Microsoft’s strategic focus on emerging technologies like enhanced rock weathering (ERW) in its sustainability efforts. Previously, Microsoft dominated the market, purchasing approximately 90% of carbon removal credits by 2025, as reported by CDR.fyi. The collaboration with Alt Carbon could signal a shift towards diversifying its carbon credit approach.
Why Choose Enhanced Rock Weathering?
Alt Carbon employs a method called enhanced rock weathering (ERW), involving spreading basalt rock dust on fields, where it interacts with rainwater. This chemical reaction transforms CO2 into stable bicarbonate ions, eventually becoming calcium carbonate in the ocean. The deal with Microsoft ensures credits will be generated from the Darjeeling Revival Project, further promoting this ERW technology.
What Benefits Does the Darjeeling Revival Project Offer?
The Darjeeling Revival Project not only focuses on carbon reduction but also aims to enhance local agriculture. By improving soil health, balancing pH levels, and increasing crop yields, this initiative could have significant agricultural impacts, benefiting both farmers and the ecosystem. The project seeks to revitalize tea estates and agricultural networks around Darjeeling.
Shrey Agarwal, CEO of Alt Carbon, stated the agreement with Microsoft stems from extensive efforts in building a robust carbon removal infrastructure. He expressed optimism about India’s leadership potential in tech-based carbon removal.
“Our deal with Microsoft is built upon years of work building high-integrity carbon removal infrastructure in India,”
he remarked.
Microsoft’s Program Director for Carbon Removal, Phil Goodman, expressed confidence in the partnership for achieving sustainable carbon removal solutions in India. As a key player in the carbon credits market, Microsoft’s participation could enhance the deployment and validation of carbon removal initiatives.
“Our contract with Alt Carbon for high-quality carbon removal uses field deployments to collect primary and secondary quantification methods for carbon quantification,”
he added.
The agreement represents Microsoft’s second carbon removal purchase announcement following its brief withdrawal from purchasing activities earlier this year. Chief Sustainability Officer Melanie Nakagawa has emphasized that the carbon removal program will evolve in pace and volume but remains integral to Microsoft’s climate strategy.
A deeper examination of this partnership reveals Microsoft’s strategic navigation within the carbon removal domain. Although they paused carbon credit procurement, their endorsement of Alt Carbon illustrates a nuanced approach towards maintaining sustainability commitments. Collaborations of this nature could act as precedent for other tech firms aiming to balance environmental and business priorities.
