AI Datacenter Boom Raises Climate Costs

The update sharpens the story with a higher-emissions figure for major tech firms and a clearer picture of policy pushback around datacenter siting, water use, and grid impacts. It also reframes China’s approach as a more explicit renewable-hub strategy for new datacenter hubs.

The story now adds a clearer policy and geographic split: US datacenter growth is increasingly tied to grid congestion, coal retention and local opposition, while China’s coordinated siting rules and clean-power requirements emerge as a more explicit countermodel. The emissions picture also sharpens, with Microsoft, Amazon and Google’s combined reported emissions rising sharply through March 2026.
