The Guardian calculated from company sustainability reports that the three companies emitted 119 million metric tonnes of carbon-dioxide equivalent in the financial year ending March 2026, up from roughly 101 million, with datacenter construction a major driver.

What happened
The Guardian calculated from company sustainability reports that the three companies emitted 119 million metric tonnes of carbon-dioxide equivalent in the financial year ending March 2026, up from roughly 101 million, with datacenter construction a major driver.
Pressure point
The total combines company disclosures and does not isolate AI's exact share. The firms retain net-zero targets, but their current construction and supply-chain emissions are moving in the opposite direction.
What to watch
Annual absolute emissions, construction versus operational shares, power sourcing, carbon-credit availability, datacenter spending, and whether 2030 and 2040 net-zero plans gain credible near-term milestones.
