The expansion of US data centers is projected to increase power emissions by 42% by 2030, erasing 15 years of climate progress.

Sierra Club expects US power emissions to hit 2.1B metric tons by 2030, up 42% on 2025 and erasing 15 years of cuts, with off-grid data centers matching Mexico (Bloomberg) https://www.bloomberg.com/news/articles/2026-10-28/us-data-center-buildout-risks-erasing-years-of-climate-progress?accessToken=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzb3VyY2UiOiJTdWJzY3JpYmVyR2lmdGVkQXJ0aWNsZSIsImlhdCI6MTc5MzIxODQ4MywiZXhwIjoxNzkzODIzMjgzLCJhcnRpY2xlSWQiOiJUTk03WTFLSVAzSVAwMCIsImJjb25uZWN0SWQiOiJGM0VENDU5NTZFRjA0QjY5QTI0NTVBNTYxRDkyNkY5NiJ9.vaYGVNos-PgwrFAeFWxa9-gyGHRxRihCe_on05i2B3A http://www.techmeme.com/261029/p17#a261029p17

New #US #DataCenters Projected to Emit More #Carbon Than All of Mexico, Erasing Years of #Climate Progress The boom is set to produce enough #greenhousegases to cancel out 15 years of declines in power-sector #emissions, according to a Sierra Club analysis. Power sector would emit 2.1 billion metric tons of #carbondioxide by 2030, that’s 618 million more tons than 2025 levels, by the Sierra Club’s calculations, or about a 42% increase. https://www.bloomberg.com/news/articles/2026-10-28/us-data-center-buildout-risks-erasing-years-of-climate-progress https://archive.is/20261028122827/https://www.bloomberg.com/news/articles/2026-10-28/us-data-center-buildout-risks-erasing-years-of-climate-progress
