Meta has named Mercer, alongside contractor Fortis Construction, to build additional mass timber buildings at its Cheyenne campus in Wyoming, a 715,000-square-foot site carrying an investment of more than $800 million. The technology group estimates the embodied carbon savings at 41 per cent across the materials the timber replaces and intends to extend it to administrative buildings, warehouses, and the data halls themselves. Microsoft opened the category in 2024 with the first cross-laminated timber data centres in Northern Virginia, a hybrid system the company estimates cuts embodied carbon by 35 per cent compared with steel and 65 per cent compared with precast concrete. Big tech now takes up to 10 per cent of all mass timber sold in the United States.
