Amazon to be water positive by 2030

Amazon Web Services, the largest cloud-computing provider, is promising by 2030 to replenish the water its massive data centres consume, the latest environmental pledge from the internet giant.

Amazon Web Services, the largest cloud-computing provider, is promising by 2030 to replenish the water its massive data centres consume, the latest environmental pledge from the internet giant.

Parent company Amazon.com Inc. said in a statement Monday it’s supporting efforts to replenish groundwater in California, the UK and India to offset the water the company’s cloud centres use.

Google has vowed to offset 120 per cent of its water usage. They revealed last week that its global data centres consume 4.3 billion gallons of water a year.

Microsoft Corp. has already committed to replenishing more water than it consumes by the decade’s end.

Data centres use a considerable amount of electricity and water to cool the racks of servers and computers. While Amazon and its rivals have disclosed more of their energy footprints, they have been less willing to share how much water they use. That’s caused political tension in areas facing droughts.

AWS declined to share the total gallons it consumes. It reported in 2021; it used a quarter litre of water for every kilowatt-hour of electricity at its data centres. That metric is the best reflection of water efficiency, said Will Hewes, global water lead for AWS.

AWS now relies on recycled water for 20 of its data centres, including two in drought-stricken California. Still, expanding that number is challenging because re-using water is often tricky in regions where utilities aren’t set up for the practice. “Water is complicated,” Hewes said.
