As data center construction surges in the US, tech firms are increasingly purchasing low-carbon concrete. By 2030, data centers are projected to require 2 million metric tons of cement, potentially emitting 1.9 million metric tons of CO2 if built with traditional concrete.
Microsoft signed a deal to buy up to 622,500 metric tons of low-carbon cement from Sublime Systems, while Amazon partnered with Brimstone and joined the Sustainable Concrete Buyers Alliance. Amazon is using low-carbon concrete in Virginia and Oregon and has invested in startups like CarbonCure.
However, the green cement industry faces challenges due to funding cuts, notably from the Inflation Reduction Act. The operational emissions from data centers can be reduced over time, but addressing embodied emissions through sustainable materials is essential for meeting climate targets.
