Tech companies' relentless push for artificial intelligence comes at an undisclosed cost to the planet. Amazon, Microsoft and Meta are hiding their true carbon footprints, buying electricity credits that inaccurately erase millions of tons of planet-warming emissions from their carbon bills, according to a Bloomberg Green analysis.

Microsoft recently announced that its emissions are 30% higher today than in 2020, when it set a goal to become carbon negative. Emissions from other technology companies are also rising. But Microsoft and other AI leaders insist the increase is due to the carbon-intensive materials used to build data centers — cement, steel and microchips — rather than the sheer amount of energy AI requires. That's because they said the energy is mostly or all from zero-carbon sources like solar and wind. (Natasha White and Akshat Rathi, more at nny360.com)
