Amazon has announced a $20 million commitment to water conservation projects along the Colorado River, a system that supplies 40 million people across the Western US. The company says the initiative is aimed at helping a crucial but dwindling water supply, according to The Verge.

The announcement comes as Amazon and other technology companies face growing scrutiny over how much water their data centers consume. The Verge notes that the company still has not disclosed how much water it uses, leaving a gap between its conservation spending and the broader questions about its own footprint.

Whether the projects will meaningfully address the river's strain remains unclear from the announcement. The source does not provide details on specific projects or expected water savings.
