Google pledges to replenish AI data centre water usage by 2030 amid US backlash
With a $17 million investment and a goal to offset consumption, Google aims to set an industry blueprint for water stewardship in the face of growing environmental scrutiny.
Google has announced five commitments to address the water intensity of its artificial intelligence data centres, pledging to replenish more water than it consumes by 2030. The measures, designed to mitigate environmental impact and address public concerns, include investing in local water infrastructure, identifying alternative sources such as reclaimed wastewater, and increasing transparency regarding its water footprint. The announcement follows widespread backlash against the rapid expansion of AI infrastructure across the United States.
The commitments come as Google parent company Alphabet seeks to raise $80 billion from stock sales to fund its technology buildout. A recent Gallup poll indicates that more than 70 percent of Americans oppose the construction of data centres in their local areas, with 18 percent citing excess water use as a key motivator. Half of respondents identified the impact on environmental resources as a primary concern, highlighting the tension between technological expansion and community resources.
Google’s global head of infrastructure and sustainability, Ben Townsend, stated that the company aims to provide a blueprint for communities to evaluate new proposals. He noted that while Google is one of many players in the sector, it is accounting for its offsite water footprint and has reduced its supply chain’s water impact through investments in waterless renewable energy. Townsend acknowledged that concerns about data centres consuming local water are valid but argued that the sector’s overall usage is often misunderstood.
In a blog post, Google vice president of global infrastructure Bikash Koley defended the operational efficiency of water cooling systems, noting they can reduce data centre energy use by approximately 10 per cent compared to air cooling. Koley claimed that US data centres use less than 1 per cent of the water that Americans use on their lawns annually. However, he acknowledged that a recent study found AI technology uses as much water annually as people drink from water bottles worldwide, underscoring the scale of the issue.
To support these initiatives, Google has committed $17 million to water stewardship projects across seven US states. The company plans to report its annual water use and has already implemented alternative sourcing in one Georgia county. Google’s prior estimates of its water use for AI have faced criticism from researchers who argue they omit indirect water usage, prompting the company to increase transparency and focus on protecting local water resources in all aspects of its operations.
