Google’s annual environment report shows that its greenhouse gas emissions have soared 48% since 2019. The tech giant said “increased data centre energy consumption and supply chain emissions” are the primary reasons behind the rise.
AI systems require a large number of computers to function effectively. The data centres that support these systems, which are essentially warehouses filled with powerful computing equipment, consume vast amounts of energy to process data and manage the heat generated by all these computers.
Google said, “While we advanced clean energy on many of the grids where we operate, there are still some hard-to-decarbonize regions like Asia Pacific where CFE isn’t readily available.”
The company added, “We’re committed to responsibly managing the environmental impact of AI by deploying three major strategies: model optimization, efficient infrastructure, and emissions reductions.”
Google remains optimistic about AI’s potential to drive positive change. However, it is also clear-eyed about its potential environmental impact and the collaborative effort required to navigate this evolving landscape.
The company additionally added, “A sustainable future requires systems-level change, strong government policies, and new technologies. We’re committed to collaboration and playing our part, every step of the way.”

According to the IEA, estimated global data centre electricity consumption represents around 1–1.3% of global electricity demand.
Golestan (Sally) Radwan, UNEP’s Chief Digital Officer, remarked, “Through increased collaboration, innovation, and implementation, together with the development of robust governance and ethical frameworks that include minimizing the environmental impact of AI itself, we must ensure that AI remains unbiased and benefits all.”
