Last year Microsoft committed to removing more carbon from the atmosphere than it puts into it by 2030, and by 2050, it will have removed enough to make up for all carbon it has ever put in. This isn’t one of those things where a company pays to not have a tree cut down to make up for their emissions, and it doesn’t ignore things like employee travel or the shuttles running around on campus. They have a follow up post from a couple months ago to talk about how it’s going and there is a whitepaper that goes into more depth.
When you think about the amount of power consumed by the enormous datacenters that Microsoft runs around the world, this is a staggering task, but when you read through that blog post, they show that it’s possible. The efforts of a single company aren’t going to change planet directly, but investments this big will have positive side effects like technological discoveries and encouraging other groups to make similar pledges.
