Microsoft emissions surge 27% as AI buildout crimps climate goals
Microsoft reported a 27% increase in greenhouse gas emissions, largely driven by the energy-intensive infrastructure required for AI development. The company joins other tech giants like Google and Amazon in struggling to balance rapid AI expansion with climate sustainability goals.
Why it matters
The report highlights the significant environmental cost of the current AI boom, raising questions about the long-term sustainability of massive data center expansion.
Microsoft's greenhouse gas emissions jumped 27% in its latest fiscal year, the tech giant disclosed Thursday , adding to a wave of worsening environmental reports from an industry racing to build AI infrastructure.
Total emissions reached 21.1 million metric tons of carbon dioxide equivalent (mtCO2e) in the fiscal year ending June 30, 2025, up from 16.7 million the prior year, according to the company's 2026 Environmental Data Fact Sheet.
The disclosure follows similar reports from Google and Amazon last week showing emissions surging 18% and 16% respectively, as all three companies acknowledged that AI infrastructure expansion is outpacing their decarbonisation efforts.
Like its rivals, Microsoft now pollutes more for every dollar it generates in revenue.
Its emissions intensity rose to 75.0 mtCO2e per million dollars of revenue from 68.1 the prior year; the first increase in at least six years -- even as revenue grew 15 percent to $281.7 billion.
