- Microsoft, Amazon, and Google's combined carbon emissions rose by nearly a fifth to 119m mTCO₂e in the past year, driven by datacentre construction for AI.
- The surge reverses previous climate efforts, with Microsoft reporting a 25% increase, Google 18%, and Amazon 16%, largely due to supply chain and infrastructure expansion.
- Critics argue that claims of sustainable clouds are marketing, and cloud migration allows other companies to outsource their carbon footprints to these tech giants.
- The AI boom is fueling massive investment, with tech companies projected to spend $765bn this year on datacentres, leading to a potential shortage of carbon credits.
