- Google and Amazon released sustainability reports this week showing their total carbon emissions rose 25% and 16% respectively in the past year, complicating both companies' net-zero pledges
- Amazon added more than 1.2 gigawatts of data center capacity in Q4 2025 alone — more than any other company globally — fueling its Scope 3 emissions spike
- Google's Scope 3 emissions jumped 2.1 million metric tons last year, now double the company's 2019 baseline, with data center construction and outfitting identified as the main driver
- Tech companies including Google have begun investing heavily in natural gas power plants to keep pace with AI's power demands, breaking from years of renewable-only growth strategies
- Semiconductor manufacturing for GPUs and memory chips — concentrated in Asian factories on fossil-fuel-dominated grids — uses potent greenhouse gases thousands of times more warming than CO2
- Both companies lean on carbon intensity metrics that the source notes China has historically used while absolute emissions kept rising, a framing the article flags as potentially masking growing footprints
Why it matters: The AI-driven emissions surge puts Amazon and Google's net-zero pledges at material risk — delivering on them will require ramping renewable purchases, funding low-carbon steel and cement at scale, and buying millions of tons of carbon removal credits, costs the companies themselves have not yet quantified.
