Microsoft is building two data centers in Northern Virginia using engineered timber products to reduce carbon impact. The wood will be encased in a thin layer of concrete for waterproofing and durability. The facilities will use cross-laminated timber for the floors and ceilings of the buildings, as well as steel and concrete. This move is part of Microsoft’s efforts to accelerate the decarbonization of its data centers and reduce its carbon footprint by 35-65% compared to traditional steel and concrete construction.
The company has set ambitious carbon targets for itself, aiming to become carbon negative by 2030. To help achieve these goals, Microsoft has launched a $1 billion Climate Innovation Fund to invest in climate startups developing products that support decarbonization efforts. Some of the companies Microsoft has invested in include those using clean power for steel manufacturing and developing low-carbon concrete solutions. Microsoft is already using CarbonCure products at some of its data centers and plans to test a small amount of Prometheus’ cement in the Virginia project.
Amazon, a competitor based in Washington, is also pursuing lower-carbon construction technologies for its data centers through its Climate Pledge Fund. Amazon has invested in companies such as CarbonCure and Brimstone, as well as an investment in a company that turns carbon dioxide into a mineral product for construction. Amazon plans to test this material in one of its European data centers. Microsoft and Amazon’s efforts reflect a broader trend in the tech industry of transitioning data centers to more sustainable and climate-friendly construction materials.
The use of cross-laminated timber in data center construction is a new approach that presents challenges due to a lack of experience among builders working with the material. While the use of engineered timber may increase construction costs, Microsoft remains committed to exploring its use in future projects. Neff mentioned that the company is excited about the potential of engineered timber as an important tool in Microsoft’s construction toolkit going forward. The two data centers in Virginia are part of Microsoft’s broader efforts to reduce its carbon footprint and accelerate the decarbonization of its operations.
Overall, Microsoft’s decision to use engineered timber products in the construction of its data centers represents a significant step towards reducing the carbon impact of its operations. By embracing innovative and sustainable construction materials, Microsoft is working towards its goal of becoming carbon negative by 2030. The company’s investments in climate startups and commitment to exploring new technologies demonstrate its dedication to sustainability and environmental responsibility in the tech industry. As data centers continue to expand, efforts to reduce their carbon footprint and mitigate climate impacts will be crucial for the industry’s long-term sustainability.
