Microsoft signed a deal to remove to permanently remove 3.3 million metric tons of carbon dioxide with Swedish energy company Stockholm Exergi, the companies announced on Monday. The contract with Microsoft is the world's largest carbon removal deal to date, Stockholm Exergi said in a statement. Carbon dioxide released from those materials during incineration will be removed from the gas emitted from the plant, liquified for transport and permanently stored underground. Stockholm Exergi is selling carbon removal certificates, equivalent to 1 million metric tons of carbon dioxide, to help companies achieve their net-zero emissions goals. "Leveraging existing biomass power plants is a crucial first step to building worldwide carbon removal capacity," said Brian Marrs, Microsoft's senior director of energy and carbon removal, in a statement.
