Microsoft Reports a Massive 25 Percent Jump in Emissions
Microsoft reported a 25 percent increase in greenhouse gas emissions, largely driven by the expansion of energy-intensive data centers for artificial intelligence. Similar trends were reported by Google and Amazon, highlighting the environmental challenges of scaling AI infrastructure.
Why it matters
The rapid growth of AI infrastructure is complicating corporate net-zero goals and raising concerns about the environmental sustainability of the tech industry's expansion.
Microsoft’s greenhouse gas pollution increased by roughly 25 percent last year, the company says in its new sustainability report released Thursday.
The report follows similar ones released by Google and Amazon last week. Together, they show a troubling trend of rising tech company emissions, driven by the global race to build out power-hungry data centers.
In a blog post announcing the report, Microsoft vice chair and president Brad Smith and chief sustainability officer Melanie Nakagawa say that the emissions increase is driven “primarily by the expansion of our datacenter infrastructure.”
A significant portion of that increase, they write, was tied to emissions from energy the company purchased or acquired to run its operations. Known as Scope 2 emissions, that greenhouse gas pollution accounted for 13 percent of Microsoft’s total.
