The United Nations is demanding transparency from artificial intelligence companies about their environmental footprint, calling for mandatory disclosure of carbon emissions, water use, and land consumption by 2030. UN Secretary-General António Guterres unveiled the AI Environmental Transparency Initiative at London Climate Action Week, arguing that tech companies have hidden the true cost of powering the AI boom from the public and from communities hosting data centers.

Why Is AI's Energy Consumption Becoming a Global Concern?

The scale of AI's environmental impact is staggering. Data centers needed to fuel artificial intelligence accounted for about 1.5% of the world's electricity consumption in 2025, and that figure is expected to nearly double to 3% by 2030. To put this in perspective, a UN report released earlier in June found that the environmental footprint of data centers already rivals some of the world's largest countries in terms of energy demand and carbon output.

The problem extends beyond electricity. The water, energy use, and pollution associated with AI will double in just four years, according to UN analysis. Currently, coal sources about 30% of the electricity consumed by data centers globally, while renewable energy supplies only 27%, natural gas provides 26%, and nuclear accounts for 15%. Despite these obvious concerns, communities are often left in the dark about the environmental impact of the infrastructure rising around them.

What Is the AI Environmental Transparency Initiative?

Guterres proposed a comprehensive framework requiring AI companies to measure and disclose the impact of their operations. The initiative calls for companies to release information about the carbon pollution they create, along with the water and land used to power their operations. Beyond transparency, the UN chief urged AI companies to commit to powering their facilities with electricity produced from renewable technologies, such as wind and solar, by 2030.

"No more hidden costs. No more shifting the burden onto those least able to bear it. It is time to come clean," said Guterres.

Many major tech companies have already vowed to power their operations using cleaner sources, with some planning to do so by the end of the decade using solar and nuclear energy, including tech giants Amazon and Google. However, the race to deploy AI has complicated those commitments, sending greenhouse gas emissions soaring and creating regulatory barriers that have hindered climate-friendly projects.

How Can AI Companies Transition to Renewable Energy?

The path forward requires concrete action across multiple dimensions:

• Measurement and Disclosure: AI companies must establish standardized methods for measuring carbon emissions, water consumption, and land use associated with their data centers and operations, then publicly report these metrics on a regular basis.
• Renewable Energy Commitments: Organizations should commit to sourcing 100% of their electricity from renewable sources like wind, solar, and hydroelectric power by 2030, with interim targets to track progress.
• Community Engagement: Tech companies must provide transparent information to local communities about the environmental impact of data center infrastructure, addressing concerns about water depletion, air quality, and land use in affected regions.

The challenge is urgent. Renewables are expected to meet just half of data center electricity demand over the next five years, leaving a significant gap that will likely be filled by fossil fuels unless companies accelerate their transition plans.

What Progress Is Being Made on Green AI Solutions?

While the UN pushes for corporate accountability, European initiatives are demonstrating practical solutions for integrating AI with sustainability goals. The European Union's LIFE Programme, which funds environmental and climate projects across Europe, showcased several AI-powered efficiency projects at the Green Transition Forum 6.0 in Sofia, Bulgaria.

One standout project, LIFE-ACCLIMATE, aims to increase crop yields, water efficiency, and energy efficiency by 25% in greenhouses in Spain using new technology including robots and artificial intelligence. The project demonstrates how AI can help greenhouse growers anticipate future challenges and make better decisions about resource use.

"By predicting pest risks, resource consumption and crop performance, farmers can make better decisions and use water, energy and inputs more efficiently," explained Oscar Rey, project coordinator for LIFE-ACCLIMATE.

Another LIFE-funded initiative, LIFE Care4Climate, renovated apartment buildings in Slovenia using sustainable and energy-efficient methods funded by blended financing, which subsequently became the standard Eco Fund financial instrument. These projects show that AI and sustainable technology can work together to reduce environmental impact while delivering practical benefits to communities.

The broader context matters too. Positive developments in renewable energy are accelerating globally. Clean power generation, largely driven by solar and wind, exceeded overall global electricity demand growth last year, and the share of renewables hit more than one-third of the world's electricity mix for the first time in modern history in 2025. Coal power saw its share fall below one-third of global generation for the first time.

However, geopolitical challenges complicate the picture. The U.S. under President Donald Trump has embraced coal, oil, and gas while slashing support for renewables and broader climate action, all amid a global energy crisis exacerbated by the U.S. war in Iran. Guterres called this situation "the mother of all energy shocks," underscoring the urgency of the moment.

The UN chief's call for transparency and renewable energy commitments represents a critical moment for the AI industry. As artificial intelligence becomes increasingly central to global operations, the environmental cost of powering these systems cannot remain hidden. Companies that embrace the AI Environmental Transparency Initiative early may find themselves better positioned to navigate future regulations and maintain public trust as climate concerns intensify.
