In 2025, Google signed new clean energy deals exceeding 12 gigawatts, enough to power the whole of Greece once operational, and matched 100% of its electricity consumption with renewable energy purchases for the ninth straight year. From 2010 to 2025, it sealed cumulative clean energy contracts totalling nearly 35 GW. Even though AI infrastructure expansion drove a 37% surge in power demand, the firm cut its operational carbon emissions by 2% year-on-year thanks to data centres far more energy-efficient than the industry average. Its hardware, software, computing optimisations and clean energy procurement helped avoid over 58 million metric tonnes of CO₂ equivalent emissions in 2025, while a suite of Google AI tools enabled external parties to slash an additional 41 million metric tonnes of CO₂ equivalent through functions including renewable energy site selection, household energy conservation, extreme weather monitoring and wildlife identification. Google is investing in advanced energy sources such as nuclear power, enhanced geothermal systems and fusion energy, and spearheading grid decarbonisation via long-term power purchase agreements. Nevertheless, Scope 3 supply chain emissions jumped 25% due to AI infrastructure buildouts, limited low-carbon power in Asia-Pacific supply chains, land shortages, high construction costs and policy barriers, laying bare the climate strains brought by AI growth. The environmental report illustrates that enterprises must coordinate AI scaling, grid decarbonisation and supply chain emission reduction, with Google’s achievements and bottlenecks serving as an ESG benchmark for the sector.
