Microsoft promises to erase its past and future carbon footprint

The announcement by the world’s largest software company reflects the rising profile of US corporate action after President Donald Trump announced in 2017 his decision to pull the United States out of the Paris Agreement, the global pact to fight climate change.

Historical emissions a new goal

Microsoft’s pledge to address its historical emissions may resonate with some developing nations which say countries that created the most carbon, and wealth in the process, are not taking responsibility for their past pollution.

US Senators Chris Coons, a Democrat from Delaware, and Mike Braun, an Indiana Republican, applauded Microsoft.

“The scope and scale of this proposal is exactly the kind of bold action we need from the business community,” the pair, chairs of the bipartisan Senate Climate Solutions Caucus, said in a statement.

Microsoft plans to cut carbon emissions by more than half by 2030 across its supply chain, an effort requiring technology that does not full

y exist, company President Brad Smith said.

He said Microsoft would widen the reach of a fee it has charged its business divisions to account for their carbon emissions.

Microsoft said it charges $US15 per metric ton for core carbon emissions internally and will expand the coverage in phases to cover all emissions. Microsoft’s price is lower than that for carbon traded in California, where it was $US17 per ton in the most recent auction, and the European Union, where it was estimated to trade at €26.57 or $US29.58, in the current quarter.

Carbon capture raises questions

Co-founder Bill Gates was an early backer of British Columbia-based Carbon Engineering, among a handful of developers of direct air capture technology.

Carbon Engineering CEO Steve Oldham said the firm’s first direct air capture plant is under construction and is expected to capture 1 million metric tons of carbon dioxide each year.

Microsoft “is at the helm of what could be a new movement towards negative emissions,” Elizabeth V. Sturcken of the Environmental Defense Fund, said in a statement, adding that the nonprofit advocacy group was eager for Microsoft to use its political influence as well.

Microsoft’s goal of removing enough carbon by 2050 to account for all its emissions since its founding in 1975 includes direct emissions from sources such as company vehicles and indirect emissions from electricity use.

Questions remain about the technology that Microsoft is considering. Sue Reid, vice president of climate and energy at US nonprofit Ceres, which works with companies on sustainability commitments, said the economics of direct air capture have yet to be worked out, and reforestation rates may not be fast enough to catch up with growing emissions.

“That math is all facing some new uncertainty and vulnerabilities tied to exacerbated climate change impact, (like there being) more wildfires,” she said.

Investors want action on climate

Microsoft’s announcement comes as big investors pay more attention to how companies tackle climate change.

Earlier this week, BlackRock CEO Larry Fink said companies must act or face investors’ anger over how unsustainable business practices might curb their future wealth.

But even as technology companies have stepped in with climate goal plans, they have faced employee criticism for doing too little.

Amazon.com, the world’s largest online retailer, last year pledged to be “net zero carbon” by 2040 and to buy 100,000 electric delivery vans from a startup, after employee activists pushed the retailer to toughen its stance on climate change.

Microsoft plans to become net zero carbon a decade earlier than Amazon, although its emissions are roughly a third of Amazon’s.

Microsoft expects to release 16 million metric tons of carbon in 2020, including indirect emissions from activities like corporate travel.

Amazon, whose cloud business is bigger than Microsoft’s, delivers billions of packages as the largest internet retailer and owns grocer Whole Foods. It emitted more than 44 million metric tons of carbon in 2018, including indirect sources.

It was not immediately clear if the figures reported by the companies were exactly comparable.

Employee activists highlight oil contracts

Microsoft and Amazon have come under fire from activist tech workers who have demanded that they stop supplying technology to oil and gas companies because of the polluting nature of fossil-fuel extraction. Microsoft in 2017 announced a multi-year deal to sell cloud services to US energy giant Chevron .

Microsoft Workers 4 Good, which says it represents Microsoft employees aiming to hold the company to its stated values, lauded the climate plan but said “this goal is incompatible with contracts that aim to increase oil extraction, a process which we know is not sustainable.”

In a blog post, Microsoft on Thursday reiterated its commitment to working with oil and gas providers, saying it is “imperative that we enable energy companies to transition” to renewable energy and carbon-capture technologies.

Bill Weihl, former director of sustainability at Facebook, said Microsoft does not take into account that its work with oil companies could outweigh the gains of measures Microsoft takes on its own carbon reduction.

“There is good stuff here,” Weihl said. “But the topline message, that this is urgent, is not matched by what they’re focusing on.”
