Microsoft is buying tons of carbon removal from Xprize startup Vaulted Deep

Microsoft’s Carbon Emissions Challenge

Microsoft is facing a significant challenge with its carbon emissions as it rapidly expands its data center operations. Since 2020, the tech giant has seen a nearly 25% increase in its carbon footprint, contradicting its commitment to becoming carbon negative by 2030.

One way Microsoft is addressing this issue is by purchasing carbon removal credits. In a recent development, the company acquired 4.9 million metric tons of carbon removal credits from Vaulted Deep, a company specializing in innovative waste management solutions. The deal, which will run until 2028, aims to offset Microsoft’s carbon emissions effectively.

The Role of Vaulted Deep

Vaulted Deep operates uniquely by repurposing solid waste that would typically end up in landfills or incinerators. By blending materials like treated sewage, excess manure, and paper sludge into a slurry and injecting it deep underground, the company has successfully removed over 18,000 metric tons of carbon dioxide. Recognized for its efforts, Vaulted Deep secured funding and support from investors like Prelude Ventures.

Microsoft’s Carbon Neutral Goals

Despite Microsoft’s investments in renewable energy sources, some essential components of its operations, such as semiconductors, still contribute to greenhouse gas emissions. In 2021 alone, the company generated 14.9 million metric tons of greenhouse gases, highlighting the need for aggressive carbon reduction strategies.

To achieve its carbon negative target by 2030, Microsoft is intensifying its efforts in carbon removal initiatives. This includes partnerships with organizations like Chestnut Carbon to reforest acres of land and collaborations with companies like CO280 to capture carbon emissions from industrial processes.
