Bloomberg reported Wednesday that Microsoft is weighing whether to delay or abandon its 2030 "100/100/0" target, the company’s pledge to match its electricity use with zero-carbon energy purchases on an hourly basis and on the same grids where it consumes power.

What changed

According to Bloomberg, the debate is being driven by the speed and cost of Microsoft’s AI data center buildout. TechCrunch separately reported that Microsoft declined to comment on the internal discussions around the tougher hourly target, but said it continues to look for ways to maintain its annual matching goal.

That distinction matters. Microsoft’s 2021 commitment went beyond buying enough renewable power over a year. The company said it would, by 2030, match 100% of its electricity consumption, 100% of the time, with zero-carbon energy purchases. In a February update, Microsoft said it had already met its nearer-term goal of matching annual electricity consumption with renewable energy purchases, supported by 40 gigawatts of contracted clean power across 26 countries.

Why it matters

This is a concrete sign of how AI infrastructure is colliding with climate commitments. Hourly matching is far stricter than annual accounting because it tries to line up power demand and carbon-free supply in real time, not just on paper over a year.

If Microsoft softens that target, it would not change the company’s existing renewable energy contracts. But it would mark a retreat from one of Big Tech’s most ambitious grid decarbonization goals just as hyperscalers race to add more AI capacity.
