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

Microsoft's carbon emissions have increased by nearly 25% since 2020, undermining its commitment to achieve carbon negativity by 2030. In response, it has begun purchasing substantial carbon removal credits, including a recent deal with Vaulted Deep for 4.9 million metric tons. Vaulted Deep works by converting waste into a slurry to sequester carbon underground. Microsoft faces challenges due to necessary materials like semiconductors lacking zero-emission alternatives. Last year, Microsoft emitted 14.9 million metric tons of greenhouse gases, significantly more than it intends to produce by 2030, prompting additional investments in carbon removal strategies.
Microsoft's carbon emissions have grown by nearly a quarter since 2020, contradicting its pledge to remove more carbon than it generates by 2030.
In an effort to address carbon emissions, Microsoft has purchased 4.9 million metric tons of carbon removal credits from Vaulted Deep for a twelve-year term.
Vaulted Deep is innovatively tackling carbon removal by turning waste like treated sewage and excess manure into a slurry, injecting it into porous rocks.
Despite investing in renewable power, Microsoft faces challenges in finding zero-greenhouse-gas alternatives for essential materials, including semiconductors.
