UN Secretary-General Antonio Guterres called on artificial intelligence companies on Tuesday to disclose their growing environmental footprint and commit to powering every data center with renewable energy by 2030. "It is time to come clean. If AI is to help build a better future, it must be honest about what it costs us now," Guterres said at London Climate Action Week, an annual gathering of policymakers, company executives and NGOs. A UN study earlier this month found that data centers consumed more electricity than all but 10 countries in 2025. By 2030, they could use more power than all but five countries.
