3 issues realized from Microsoft’s carbon elimination report

Microsoft is a kind of firms we write about rather a lot at GreenBiz, because it has usually been on the forefront of sustainability. Whereas different organizations are targeted totally on attending to carbon impartial for present emissions, Microsoft plans to offset its whole historic emissions going again to when the corporate was based in 1975.

The software program powerhouse has definitely been busy. Early this yr, it launched the Carbon Name, a collaboration with the ClimateWorks Basis to develop dependable and correct carbon accounting instruments for firms and states monitoring their carbon emissions. Microsoft can also be constructing a cloud software for managing and monitoring sustainability metrics like emissions, sourcing suppliers and waste. Its quest to go carbon unfavourable within the subsequent 10 years additionally impressed a $1 billion fund for carbon discount, seize and elimination applied sciences.

Microsoft’s latest carbon elimination report, issued in March, affords a deeper glimpse into its efforts to go web zero by 2030, a aim many different firms are reaching for over the following decade. It’s the third such replace detailing its carbon elimination efforts; in 2021, Microsoft revealed reflections on its 2020 work and in early March, it revealed an analogous evaluation for 2021. 

Among the many core particulars within the newest report: In 2020, the corporate invested in tasks driving 1.4 million metric tons of CO2 elimination, equal to emissions from 301,657 automobiles pushed for one yr, in line with the EPA calculator. In 2021, Microsoft bumped its purchases as much as 1.5 million metric tons and picked up carbon emissions knowledge from 87 p.c of its suppliers.

However whereas the corporate’s Scope 1 and a pair of emissions decreased by 17 p.c, Scope 3 stubbornly rose 23 p.c yr over yr. Based on Microsoft, most of that enhance got here from Xbox enterprise development and an increase in demand for cloud companies comparable to Microsoft Workplace, which result in an increasing international datacenter footprint. To fight this sooner or later, Microsoft is growing the payment it fees enterprise models for enterprise journey to $100 per metric ton of CO2, adapting the best way it units carbon emission discount targets, growing the frequency of inside reporting and elevating its inside carbon worth.

Listed below are three issues we realized from Microsoft’s newest carbon elimination report:

1. Good removals would require extra rigorous and clear RFPs

Microsoft reported that it acquired 17 p.c fewer functions and 43 p.c fewer proposals for third-party carbon elimination tasks in response to its request for proposals (RFPs) in 2022 in comparison with 2021. In 2022, Microsoft acquired 67 candidates with about 106 tasks in 35 nations.

Based on the report, Microsoft believes “the decrease response price displays our clearer standards this yr, higher provider consciousness of the excellence between carbon elimination and carbon avoidance (regardless of the shortage of frequent requirements) and excessive demand for tasks.”

Earlier than the RFP, Microsoft launched a standards for elimination tasks with Carbon Direct, a carbon asset supervisor that additionally works with Shopify. The standards outlined extra particularly that Microsoft was searching for proposals from tasks that will instantly take away carbon from the ambiance somewhat than averted emission tasks (comparable to defending an already standing forest). Based on Elizabeth Willmott, carbon program supervisor at Microsoft, by doing this the corporate received much less proposals this yr for tasks that weren’t carbon removals and minimize down on the quantity of vetting her workforce needed to do to seek out the appropriate tasks to spend money on. 

2. Biochar continues to achieve traction

Sturdiness or permanence, which means how lengthy the carbon may be estimated to be saved, is a key issue for carbon offsets. Microsoft’s portfolio is a mixture of excessive, low and medium sturdiness tasks. Excessive sturdiness tasks, comparable to direct air seize, are estimated to retailer carbon for over 10,000 years, whereas low sturdiness, nature-based ones comparable to planting a forest or mangrove, not often get estimated to final above 100 years. Microsoft simply recognized six biochar tasks for its medium-durability time period answer, which it estimates will sequester carbon for between 200 and 1,000 years.

Biochar is charcoal created from biomass, decomposing agriculture or forestry waste in an surroundings with out oxygen, that can be utilized to sequester carbon within the soil whereas additionally growing the well being of these soils.

Biochar is being newly embraced as a real carbon elimination answer at scale.

The biochar tasks backed by Microsoft embrace, Carbonfuture, Local weather Robotics, Carbofex, ECHO2 and Carbon Cycle. The tasks span from Oregon, Texas and California to Finland, Australia and Germany. The most important contracted quantity for elimination is 6,926 metric tons from the Freres Biochar venture, which generates steam for lumber manufacturing utilizing a biomass boiler with lumber scraps and native waste used as feedstocks. The biochar is created as a byproduct of this course of. The opposite tasks hover across the stage of 1,000 metric tons of elimination and use feedstocks comparable to bark, meals waste, spruce thinnings and wooden chips.

“It’s what was out there when it comes to medium sturdiness options that have been comparatively reasonably priced and in provide in the marketplace,” Willmot mentioned. “It’s being newly embraced as a real carbon elimination answer at scale.”

Different company leaders in carbon removals, comparable to Shopify, have additionally began to spend money on biochar options.

3. A transfer away from direct air seize

For prime sturdiness options, the frequent one which has been in direct air seize (DAC), the place machines pull carbon instantly out of the air for sequestration. Legacy gamers, comparable to Climeworks and Carbon Engineering, which have each been round since 2009 and have over $100 million in funding every, are working with Shopify, Stripe and Microsoft.

Nevertheless this yr, Microsoft has diversified its excessive sturdiness, “holy grail” carbon elimination options. The software program large is working with two early-stage firms that provide long-term options, Appeal Industrial and Neustark, which the Division of Vitality’s Carbon Direct Removing database categorizes as biomass injection expertise and mineralization, respectively. 

Appeal Industrial injects a bio-oil created from plant and crop biomass that comprises atmospheric carbon deep into the earth. Neustark sequesters CO2 from biogas from crops into concrete for development.

“These kind of hybrid options are actually attention-grabbing,” Willmott mentioned. “We’re very excited to spend money on and procure from firms which can be attention-grabbing startups and which can be rising the longer term provide.”

Microsoft described these applied sciences as storing carbon for 10,000 years however solely contracted 300 metric tons (equal to 65 gas-powered automobiles pushed for a yr) whole from the 2 5-year-old startups on this younger sector.

Based on Willmott, a giant motive Microsoft selected these applied sciences was as a result of these startups have been reasonably priced. 

At present, Microsoft fees a carbon payment of $15 a ton on emissions throughout all three scopes, however the carbon elimination purchases solely cowl Scopes 1, 2 and enterprise journey (The corporate plans to cowl all three scopes in 2030).

The additional cash from the interior carbon payment on Scope 3 emissions permits the corporate to purchase costlier elimination purchases. The common worth it paid to the carbon venture creators throughout all of the removals this yr was $19.40 per ton.

“The rise within the carbon payment has been labored on for the previous few years in order that we might get the funding that we have to principally fulfill this increased sturdiness portfolio as a result of even for a giant firm, like Microsoft, affordability is known as a concern,” she mentioned.
