Datacentres drive up big tech’s carbon emissions to a third of those of France

Microsoft, Amazon and Google say they still aim to achieve net zero output despite construction boom

Microsoft, Amazon and Google’s collective carbon emissions have increased by nearly a fifth in the past year, driven largely by datacentre construction.

In the financial year ending March 2026, the three tech companies emitted 119m mTCO₂e (metric tonnes of carbon dioxide equivalent), or about a third of those of France.
