Microsoft faces potential vote: Shareholders curious about its plans to tackle emissions
Trillium Asset Management is urging Microsoft shareholders to back a proposal asking the company to explain how it plans to meet its 2030 climate targets. The request comes as Microsoft’s emissions have risen alongside rapid growth in AI and cloud services, raising questions about how it will reconcile expanding infrastructure with its carbon-negative pledge.
Microsoft’s reported emissions increased from 13 million tonnes of CO2 equivalent in 2020 to 20 million in 2025, or 62 per cent above its baseline; the company estimates they would have reached about 34 million tonnes without its existing initiatives. Most of the rise is linked to Scope 3 emissions from data centre construction and supply, while Scope 2 emissions from purchased energy rose to 13 per cent of the total in 2025, from 2 per cent in 2024. Trillium wants annual disclosure of a climate transition plan, while Microsoft recommends shareholders reject the proposal, saying its current disclosures are sufficient and the requested forecasts would be uncertain.
In short
- Microsoft’s emissions rose 62 per cent above their 2020 baseline.
- Trillium wants shareholders to seek a clearer climate plan.
- Microsoft recommends voting against the proposal.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Shareholders could reasonably support the proposal because Microsoft’s emissions have risen substantially as it expands AI and cloud services, making its 2030 targets harder to assess. Annual disclosure of a transition plan could help investors understand how the company intends to manage that growth, track progress and judge whether its existing initiatives are sufficient.
The case against
Shareholders could reasonably reject the proposal if they consider Microsoft’s existing climate disclosures adequate and believe additional forecasts would be too uncertain to guide decisions. Preparing a separate annual plan could add reporting burdens without improving accountability, while the company’s current initiatives may already explain how it is addressing emissions from its expanding operations and supply chain.
Explained simply
Microsoft has pledged to become carbon negative by 2030, meaning it aims to remove more carbon from the atmosphere than it emits. Its emissions have risen as it expands cloud computing and artificial intelligence services, which require large data centres and the energy and materials to build and run them.
Trillium Asset Management is an investment firm that holds Microsoft shares and is asking shareholders to support a proposal for more detail on how the company will meet its climate targets. The proposal seeks annual disclosure of a transition plan; Microsoft’s board says existing reports provide enough information and recommends voting against it.
The vote is part of a wider question facing technology companies: how to expand computing infrastructure while reducing emissions. Microsoft’s reported emissions include those from its suppliers and construction as well as the energy it buys, so its targets depend on changes across its operations and supply chain.
