United Nations calls on AI firms to set emissions targets as data centers devour global energy

The United Nations is done asking nicely. On June 23, UN Secretary-General António Guterres launched the AI Environmental Transparency Initiative during London Climate Action Week, calling on major AI companies to fully disclose their carbon emissions, water consumption, and land use. The initiative also sets a concrete benchmark: 100% renewable energy powering AI data centers by 2030.

Current projections suggest data centers could consume up to 945 terawatt-hours of electricity annually by 2030, roughly 3% of total global energy demand. To put that in perspective, that figure would exceed the energy consumption of all but five countries on Earth.

The numbers behind the pressure

The initiative didn’t materialize out of thin air. It was prompted by a June 2026 report from the UN University Institute for Water, Environment and Health, which mapped out the environmental footprint of AI infrastructure in sobering detail.

AI-driven water consumption could match the annual domestic water needs of approximately 1.3 billion people in sub-Saharan Africa. The physical land footprint of AI data centers, meanwhile, could exceed 14,500 square kilometers by 2030, an area roughly the size of Montenegro.

A prior estimate pegged data-center electricity use at 448 TWh in 2025, with AI workloads accounting for about 20% of that total. By 2030, AI workloads are projected to represent 40% of data-center electricity consumption, effectively doubling their share in five years.

Indirect emissions from major tech firms rose 150% between 2020 and 2023, driven largely by data-center expansion.

UN officials are not mincing words

Simon Stiell, Executive Secretary of the UN Framework Convention on Climate Change, described AI as “energy-guzzling” and warned that public trust in major tech companies is eroding as energy costs rise and emissions climb.

The COP31 presidency is attempting to formalize these concerns into binding commitments. An initiative called the “Antalya Pledge on AI” aims to lock in transparency requirements and clean energy practices for AI development. If adopted, it would represent the first major international climate framework specifically targeting the AI industry.

Google, Microsoft, and Meta have all made net-zero commitments, yet their actual emissions trajectories have moved in the opposite direction as they race to build out AI capacity.
