Microsoft, which normally leaves shopping for development supplies to its contractors, has signed a long-term contract to purchase low-carbon cement by startup Elegant Programs. It is going to use a brand new type of environmental credit associated to that buy to say emissions reductions associated to knowledge middle development.
Underneath the deal, introduced Could 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 % of the expertise firm’s whole 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 knowledge facilities, infrastructure and places of work wherever geographically doable. Most cement is used inside a couple of hundred miles of the place it’s produced.
Microsoft’s footprint rose 31 % between 2020 and 2024, largely due to knowledge middle enlargement. Concrete and metal are carbon-intensive supplies that collectively contribute 13 % of world carbon dioxide emissions. With a lot ado being made concerning the large power urge for food of information facilities that gas synthetic intelligence, Amazon, Google and Microsoft are all searching for methods to handle their construction-related emissions.
Elegant makes use of an electrochemical course of as a substitute 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 Influence Companions, together with an $87 million award by the Division of Vitality in 2024 — funding that thus far 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,” stated Elegant CEO and Co-founder Leah Ellis. The U.S. imports greater than 20 % of its cement, and Elegant’s expertise may change that locus. Two factories within the Northeast have closed previously 18 months due to outdated applied sciences.
Microsoft is the anchor buyer for Elegant’s first business facility being in-built Holyoke, Massachusetts, slated to start deliveries in 2028. One of many largest development corporations within the Northeast, Suffolk, introduced a $3 million funding on Could 21 to purchase cement from the manufacturing unit.
“Elegant’s mission is at least basically reshaping a cornerstone of the worldwide constructed surroundings panorama, and we’re proud to assist them via our capital, our community and our dedication to constructing a extra sustainable world,” stated Jit Kee Chin, govt 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 approach to offer early demand indicators for the startup’s first manufacturing unit, which is able to produce about 30,000 tons of cement yearly. “Microsoft is a market maker,” Ellis stated.
Elegant’s first business 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 stated.
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 corporations use to calculate emissions reductions. One frequent sort 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 probably be issued beneath the Microsoft-Elegant deal are based mostly on a technique Microsoft developed with carbon administration consulting agency Carbon Direct.
“Whereas we prioritize deploying bodily materials each time doable, this EAC method helps each patrons and sellers overcome geographic, provide chain, price and different limitations that make it difficult to introduce new applied sciences,” stated Katie Ross, director of carbon discount technique and market growth at Microsoft.
Purpose: Scale availability of low-carbon cement
Microsoft’s purchases will probably be independently verified, though the main points of how that can occur haven’t but been decided, stated A.J. Simon, director of commercial decarbonization at Carbon Direct. The certificates will probably be managed by a e-book and declare system, much like what’s in place for sustainable aviation gas.
The methodology printed as a information for different corporations recommends that certificates be vetted utilizing seven standards, comparable to 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 can enhance confidence on this mechanism,” Simon stated. “The thresholds for high quality within the report replicate Microsoft’s decarbonization; different corporations could determine to weight the standards in another way.”
The prepurchase commitments made doable by the EACs act as accelerants for startups, Ellis stated. Regardless of unsure macroeconomic situations, Elegant isn’t making huge 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 business that pivots shortly,” Ellis stated.
