Microsoft, which often leaves shopping for development supplies to its contractors, has signed a long-term contract to purchase low-carbon cement by startup Elegant Methods. It would use a brand new type of environmental credit associated to that buy to say emissions reductions associated to information middle development.
Beneath the deal, introduced Might 22, Microsoft will declare 622,500 metric tons of emissions reductions over a six-to-nine-year interval towards its Scope 3 footprint — which accounted for 96.5 p.c of the expertise firm’s complete footprint in its 2023 fiscal 12 months.
For perspective, Microsoft used 605,000 carbon credit that 12 months to make its carbon impartial declare. It has additionally bought credit for shut to twenty million tons of carbon elimination.
Microsoft plans to make use of Elegant’s cement in information facilities, infrastructure and workplaces wherever geographically attainable. Most cement is used inside just a few hundred miles of the place it’s produced.
Microsoft’s footprint rose 31 p.c between 2020 and 2024, largely due to information middle enlargement. Concrete and metal are carbon-intensive supplies that collectively contribute 13 p.c of world carbon dioxide emissions. With a lot ado being made concerning the large power urge for food of knowledge facilities that gasoline synthetic intelligence, Amazon, Google and Microsoft are all in search of methods to handle their construction-related emissions.
Elegant makes use of an electrochemical course of as an alternative of a combustion-driven kiln to fabricate a substitute for abnormal portland cement. The corporate, spun out of analysis on the Massachusetts Institute of Expertise, has raised $200 million. That features funding from enterprise capital companies together with The Engine, Lowercarbon Capital and Vitality Affect Companions, together with an $87 million award by the Division of Vitality in 2024 — funding that to this point has not been affected by the Trump administration’s shifting priorities.
“We see a giant alternative to each cultivate and modernize U.S. cement making,” mentioned Elegant CEO and Co-founder Leah Ellis. The U.S. imports greater than 20 p.c of its cement, and Elegant’s expertise may change that locus. Two factories within the Northeast have closed up to now 18 months due to outdated applied sciences.
Microsoft is the anchor buyer for Elegant’s first industrial facility being in-built Holyoke, Massachusetts, slated to start deliveries in 2028. One of many largest development firms within the Northeast, Suffolk, introduced a $3 million funding on Might 21 to purchase cement from the manufacturing facility.
“Elegant’s mission is at least basically reshaping a cornerstone of the worldwide constructed setting panorama, and we’re proud to assist them by way of our capital, our community and our dedication to constructing a extra sustainable world,” mentioned Jit Kee Chin, government vp and chief expertise officer for Suffolk’s funding arm, Suffolk Applied sciences.
Credit for low-carbon cement and metal
Phrases of the Microsoft-Elegant deal weren’t disclosed, however the firm is positioning the contract as a manner to supply early demand alerts for the startup’s first manufacturing facility, which can produce about 30,000 tons of cement yearly. “Microsoft is a market maker,” Ellis mentioned.
Elegant’s first industrial deliveries are slated for 2028; the startup hopes to assist a full-scale facility with a capability of 1 million tons probably by 2030, she mentioned.
Microsoft is utilizing a brand new class of environmental attribute certificates (EAC) for concrete and metal to justify its funding. The certificates are authorized mechanisms firms use to calculate emissions reductions. One widespread kind is renewable power certificates, which many companies use to offset emissions from bought electrical energy.
Environmental attribute certificates are used to spur investments in applied sciences that decarbonize hard-to-abate sectors together with aviation, freight rail and maritime transport. The brand new ones that will likely be issued below the Microsoft-Elegant deal are based mostly on a strategy Microsoft developed with carbon administration consulting agency Carbon Direct.
“Whereas we prioritize deploying bodily materials at any time when attainable, this EAC method helps each consumers and sellers overcome geographic, provide chain, value and different obstacles that make it difficult to introduce new applied sciences,” mentioned Katie Ross, director of carbon discount technique and market improvement at Microsoft.
Aim: Scale availability of low-carbon cement
Microsoft’s purchases will likely be independently verified, though the main points of how that may occur haven’t but been decided, mentioned A.J. Simon, director of business decarbonization at Carbon Direct. The certificates will likely be managed by a e book and declare system, much like what’s in place for sustainable aviation gasoline.
The methodology revealed as a information for different firms recommends that certificates be vetted utilizing seven standards, reminiscent of whether or not purchases will complement direct procurement of metal, cement and concrete.
“The intention is to set high-integrity requirements for commodity EACs that may enhance confidence on this mechanism,” Simon mentioned. “The thresholds for high quality within the report mirror Microsoft’s decarbonization; different firms might determine to weight the factors in a different way.”
The prepurchase commitments made attainable by the EACs act as accelerants for startups, Ellis mentioned. Regardless of unsure macroeconomic circumstances, Elegant isn’t making massive changes, and it’s working carefully with three of the world’s largest cement producers — Holcim, Amrize and CRH — to deal with the long run. “This isn’t an trade that pivots shortly,” Ellis mentioned.
