UN Chief Demands AI Companies Disclose Climate Impact by 2030

United Nations Secretary-General António Guterres issued a direct challenge to artificial intelligence companies this week: publicly report the environmental toll of your operations and transition to renewable energy within six years.

Speaking at London Climate Action Week on Tuesday, Guterres unveiled the AI Environmental Transparency Initiative, which calls on AI firms to measure and disclose carbon emissions, water consumption, and land use associated with their data center operations. He also urged these companies to power their facilities entirely with renewable electricity by 2030.

"No more hidden costs," Guterres told attendees at Europe's largest independent climate conference. "No more shifting the burden onto those least able to bear it. It is time to come clean."

The scale of AI's environmental footprint

The urgency behind Guterres' call reflects mounting evidence of AI's climate impact. Data centers supporting AI consumed approximately 1.5% of global electricity in 2025, according to a recent UN report. That figure is projected to nearly double to 3% by 2030.

The same report found that water use, energy consumption, and pollution from AI infrastructure will double within just four years. The environmental footprint of data centers now rivals that of some of the world's largest countries.

Currently, coal supplies roughly 30% of data center electricity globally, according to the International Energy Agency. Renewable sources—primarily wind, solar, and hydropower—account for only 27%, with natural gas at 26% and nuclear at 15%. Renewables are expected to meet just half of new demand over the next five years.

Why it matters

The AI boom has created a direct conflict with corporate climate commitments. While tech giants including Amazon and Google have pledged to power operations with clean energy by decade's end, the explosive growth of AI workloads has sent their greenhouse gas emissions soaring instead of declining. Communities hosting data centers often lack basic information about the facilities' environmental impact, even as they bear the burden of increased energy demand and water consumption. Standardized disclosure requirements could force the industry to account for costs currently externalized to local populations and the climate.

Tech industry faces mounting pressure

Major technology companies have faced increasing demands for transparency from both governments and communities near data center sites. Many firms have announced renewable energy commitments, with some planning significant investments in solar and nuclear power. However, regulatory obstacles have slowed climate-friendly projects, and the race to deploy AI has complicated existing sustainability pledges.

Guterres acknowledged AI's potential to accelerate climate solutions through improved energy efficiency and reduced emissions. Yet he emphasized that communities are "often left in the dark about the environmental impact of the infrastructure rising around them."

Broader climate context

The AI transparency initiative represents one element of Guterres' broader climate agenda ahead of this year's Conference of Parties in Turkey. He called for action to keep global warming below 1.5 degrees Celsius compared to pre-industrial levels—a threshold that was breached for the first time last year when measured as a three-year average.

Guterres noted positive developments in renewable energy adoption, including clean power generation exceeding global electricity demand growth last year. Renewables reached more than one-third of the world's electricity mix for the first time in modern history in 2025, while coal's share fell below one-third.
