Big Tech Data Centers Push Emissions to a Third of France’s Output

The rapid expansion of data centers by the world’s largest cloud providers has driven a sharp rise in their carbon footprints. In the fiscal year ending March 2026, Microsoft, Amazon and Google together emitted 119 million metric tonnes of CO₂e, roughly a third of France’s national emissions. This marks a near‑20% jump from the previous year’s 101 million tonnes and comes as demand for AI‑driven cloud services soars. The surge challenges the companies’ public net‑zero pledges and puts pressure on policymakers to account for digital‑sector emissions.

What happened

The three firms disclosed their 2025‑2026 sustainability data in recent reports. Microsoft recorded a 25% rise to 20 million tonnes CO₂e, attributing the increase primarily to new data‑center construction. Google’s emissions grew by 18%, driven by supply‑chain activity that supports its expanding data‑center portfolio. Amazon reported a 16% overall increase, with a 20% jump in supply‑chain emissions tied to data‑center building and related logistics.

Collectively, the trio’s emissions climbed from about 101 million tonnes the prior year to 119 million tonnes, a level comparable to the entire output of France. The growth aligns with a broader AI boom, as training large models and delivering cloud services demand ever‑larger, power‑hungry facilities.

Why it matters

Rising emissions undermine the companies’ net‑zero timelines—Microsoft aims for 2030, Google for 2030, and Amazon for 2040—while the sector’s carbon intensity threatens broader climate targets. Policymakers may need to tighten reporting standards and consider the indirect emissions of digital services. For enterprises, the hidden carbon cost of migrating workloads to the cloud could offset sustainability gains elsewhere.

How to think about it

When evaluating cloud providers, look beyond headline net‑zero claims and examine Scope 1, 2 and 3 emissions separately. Prioritize vendors that disclose concrete renewable‑energy purchase agreements and have clear timelines for phasing out fossil‑fuel‑based data centers. Incorporate the carbon cost of data‑transfer and storage into your own sustainability metrics, and consider offsetting strategies only after direct reductions are maximized. Finally, balance AI workload placement with regional energy mixes to favor low‑carbon grids.
