LONDON — UN Secretary-General António Guterres has issued a stern call to action for the global artificial intelligence industry, demanding full transparency regarding the environmental footprint of AI systems. Addressing leaders at London Climate Action Week on June 23, 2026, Guterres unveiled the "AI Environmental Transparency Initiative," a landmark effort aimed at curbing the ecological costs of the AI boom. 

The Call for Accountability

The Secretary-General urged major AI corporations to disclose the comprehensive environmental impacts of their operations, specifically highlighting carbon emissions, water consumption, and land usage. Furthermore, he set a clear industry target: all data centers must be powered by renewable energy by 2030. 

"There should be no more hidden costs," Guterres stated during his address. "If AI is to help us toward a better future, we must be honest about what it is costing us". He emphasized that the burden of this technological advancement should not fall upon those least equipped to manage it. 

The Escalating Environmental Footprint

The urgency of this initiative is underscored by rapid increases in energy demand. According to recent reports, global data center electricity consumption is projected to climb from approximately 415 terawatt-hours (TWh) in 2024 to 945 TWh by 2030—a figure nearly triple the combined annual energy consumption of countries like Pakistan, Bangladesh, and Nigeria. 

While AI models have gained public attention, the report highlights that daily usage—specifically inference—accounts for roughly 80% to 90% of total energy demand. Beyond electricity, the "water footprint" required for cooling these massive facilities and the physical land demand, projected to exceed 14,500 square kilometers by 2030, represent significant ecological challenges that often go undisclosed by private firms. 

Cities Unite: The Global Urban Data Centres Pact

Complementing the UN’s initiative, a coalition of 41 cities across six continents launched the "Global Urban Data Centres Pact" during the same week. Mayors from major hubs—including London, Sydney, Barcelona, and Phoenix—voiced concerns over the strain placed on local power grids, water resources, and community infrastructure by the proliferation of data centers. 

The pact outlines a vision for data centers that are "strategically integrated" into urban planning, prioritizing sustainability and resource efficiency rather than purely expansionist goals. London Mayor Sadiq Khan noted that while digital infrastructure is central to urban prosperity, residents have a right to ensure that such growth is managed responsibly and sustainably. 

As global AI capacity continues to grow at a compound annual rate of 12%, the dual efforts of the UN and this international mayoral coalition signal a shifting regulatory landscape. The message is clear: for the AI industry to sustain its rapid development, it must align its growth with global climate targets and demonstrate accountability to the local communities that host its infrastructure.
