Microsoft plans to achieve its goal to become carbon negative by using direct air capture (DAC) systems that provide engineered carbon removal credits.

It partnered with CarbonCapture Inc., a U.S. climate tech company that develops DAC systems based on a modular open systems architecture, which can be deployed in large arrays.

Microsoft will source its carbon removal credits from Project Bison. Currently being developed at a large facility in Wyoming, this project features a phased rollout plan to capture and store five million tons of atmospheric CO2 per year by 2030. As the first massively scalable DAC project in the U.S., it will use Class VI injection wells to permanently store CO2 captured from ambient air using DAC technology.

“Purchasing DAC carbon removal credits is an important part of Microsoft’s pursuit of permanent, durable carbon removal. This agreement with CarbonCapture helps us move toward our carbon negative goal, while also helping to catalyze the growth of the direct air capture industry as a whole,” Phillip Goodman, Director, Carbon Removal Portfolio at Microsoft, said in a statement,
