Microsoft has once again turned to Canadian tech to achieve its goal of being carbon-negative by 2030.

Vancouver-based carbon capture startup Arca has struck a 10-year deal with the tech giant to remove nearly 300,000 tonnes of carbon dioxide (CO2) from the air. Arca’s CO2 capture solution relies on carbon mineralization, a natural process that transforms gaseous carbon into rock. Arca uses microwave radiation to break down certain minerals found in mining byproducts, making them bind with CO2.

Arca “has proven they can sequester carbon through their demonstration project, giving us confidence to enter into a multi-year agreement.”

“This agreement with Microsoft validates industrial mineralization as a viable pathway for durable carbon removal with the potential to scale and meaningfull
