Microsoft is pausing new carbon removal purchases while its emissions have risen 23.4% since 2020 (Technology Review, 2026; Microsoft Environmental Sustainability Report, June 2025).

Microsoft accounts for roughly 80% of contracted carbon removal volumes, per CDR.fyi co-founder Robert Höglund (Technology Review, Apr. 16, 2026). Heatmap News reported the pause on Apr. 10, 2026, followed by Bloomberg citing financial considerations; Microsoft stated adjustments are part of a disciplined approach and not a change in ambition, according to Chief Sustainability Officer Melanie Nakagawa (Heatmap News, 2026; Bloomberg, 2026; Technology Review, 2026). The company has pledged carbon-negative status by 2030 and removal of all historic emissions by 2050.

Company emissions growth tracks AI infrastructure expansion, with data center power demand forecast to double by 2030 and AI adding up to 160% to loads, per Goldman Sachs analysis and IEA data (Goldman Sachs, 2024; IEA World Energy Outlook, 2024). Similar emission increases reported by Google and Amazon tied to AI investments (Google Environmental Report, 2024).

Original coverage noted industry nervousness and Microsoft's market role but did not connect the pause to documented AI-driven energy patterns or IPCC calls for up to 11 GtCO2 annual removal by 2050 (IPCC via UN Climate Report, 2022). Wil Burns of American University called the rollout irresponsible given reliance on Microsoft by most CDR developers (Technology Review, 2026).
