Microsoft made a giant climate pledge one year ago — here’s where it’s at now

One 12 months after pledging to take away all of its historic and future planet-heating emissions inside a number of many years, Microsoft says it has already slashed its carbon footprint by 6 p.c. It’s an incremental change that’s in step with what’s wanted globally to deal with the local weather disaster, however there’s a entire lot of labor left for Microsoft to do.

Last January, Microsoft pledged to do one thing that, on the time, was fairly unheard-of: it deliberate to develop into carbon unfavorable by 2030. That gave the corporate a deadline to seize extra planet-heating carbon dioxide than it emits. Not solely wouldn’t it goal future emissions, however the firm additionally pledged that, by 2050, it might take away the equal of all of the carbon dioxide it’s launched since being based in 1975. It made these guarantees despite the fact that the know-how to make all of it occur doesn’t but exist at business scale.

Now, we’re starting to get a glimpse of what’s really possible for Microsoft to attain. Among the discount in local weather air pollution it achieved final 12 months was a results of the financial toll of the pandemic. Microsoft might want to proceed making cuts 12 months on 12 months with out the assistance of a worldwide disaster. The sustainability report it launched in the present day additionally confirmed how a lot the corporate can really depend on carbon-removal applied sciences — which, in the mean time, just isn’t very a lot.

When corporations set objectives to develop into carbon impartial, or carbon unfavorable in Microsoft’s case, the corporate isn’t saying it should cease pumping out greenhouse gases altogether. What it will do is cancel out some portion of its greenhouse gases by paying different corporations and nonprofit organizations to lure and retailer carbon dioxide. The tough a part of these company sustainability pledges is that it’s not often clear how a lot carbon dioxide the corporate plans to chop altogether versus how a lot it should proceed to pollute after which pay to take away from the ambiance.

In Microsoft’s case, we now know that the corporate plans to chop its emissions “by greater than half” by 2030. That suggests that, sooner or later, it intends to depend on carbon-removal schemes to make up for nearly half of all its carbon emissions. In its 2020 fiscal year, Microsoft launched 11,164,000 metric tons of carbon dioxide equal. Since making its carbon-removal pledge final January, the corporate says it bought contracts to seize 1.3 million metric tons of CO2, over 11 p.c of its whole.

Firms can take away carbon dioxide from the ambiance by funding reforestation initiatives or know-how that captures the greenhouse gasoline from the air. To this point, Microsoft has relied mostly on forests to suck up and retailer its carbon emissions. Lower than 1 p.c of the carbon Microsoft mentioned it faraway from the ambiance final 12 months was seized via rising direct air seize applied sciences.

“Right now there isn’t a actual present carbon removing ecosystem and the world should construct a brand new market on an unprecedented scale and timeline, from almost scratch,” Microsoft president Brad Smith mentioned in a blog submit in the present day. Microsoft began a $1 billion Local weather Innovation Fund final 12 months to speed up the expansion of that “ecosystem,” however far more will likely be wanted to make carbon removing a profitable technique.


Firms counting on forests to erase their carbon footprint comes with pitfalls, too. Though the technique is now being folded into the umbrella time period of “carbon removing,” it’s usually been described prior to now as carbon “offsets.” Offsets have gotten a nasty rap as a result of investigations into them have proven that they haven’t really succeeded in completely trapping carbon dioxide. Firms can declare that they’re canceling out their impact on the local weather, when in actuality, they’re not.

Microsoft funded three conservation initiatives via the Nature Conservancy, which was the topic of a Bloomberg investigation final 12 months. A few of Nature Conservancy’s forest preservation initiatives allowed corporations to assert they had been shrinking their carbon footprints, when in actuality, the forests weren’t threatened — so there was no further profit they had been including to the local weather.

Microsoft acknowledges that its reliance on these sorts of conservation initiatives is a “large weak point” in its preliminary work. “Reflecting the state of the market in the present day and our instant want for carbon removing, almost all of the carbon removing options we’re buying are short-term and nature-based,” Smith wrote. “This isn’t the rocket that may take us to the Moon. The world must invent considerably stronger technology-based options than can be found in the present day.”

The world, together with Microsoft, additionally must double down on efforts to cease polluting within the first place. Microsoft has laid out some plans on the way it will try this. It’s tying executives’ pay to their efficiency on sustainability initiatives. The corporate mentioned it should additionally work with suppliers to chop down their air pollution.

It additionally incentivizes groups inside the firm to give you methods to make their merchandise extra sustainable. One notable end result from this system: the corporate up to date the Xbox to scale back the facility it makes use of when it’s in “standby mode” from 15W to lower than 2W. (Facet be aware: settings still make a really big difference in terms of making the console as vitality environment friendly as doable, in line with the nonprofit Pure Assets Protection Council.)

Microsoft may also have to determine find out how to cut back emissions from its knowledge facilities, which suck up numerous vitality and are an important a part of its enterprise. It’s already regarded into storing servers under the sea, which may save vitality by protecting the servers cool naturally with out requiring refrigeration. Information facilities on land can even deplete numerous water as a part of their cooling programs. Microsoft pledged last year to preserve and replenish water the place it operates.

Microsoft’s purpose of halving emissions by 2030 falls in step with science-based targets. With a purpose to keep away from probably the most extreme results of local weather change, the worldwide financial system might want to roughly halve emissions by 2030, in line with a landmark report by main local weather scientists. By 2050, the world might want to intestine emissions to close zero. Carbon removing could provide a small help, however to get to the Moon, the heavy lifting should come from elsewhere.
