The subsequent time you buy a brand new laptop computer, you may discover an possibility for added guilt on the checkout web page: Some laptop computer makers have began providing “carbon offsets” that declare to cancel out all of the emissions that go into making your laptop computer. However sadly, it’s not that easy. We spoke to 5 specialists to find out about offsets. We additionally dug deep into two obtainable offset applications to seek out out whether or not they’re definitely worth the cash, and if not, to study what you need to do as a substitute if you happen to care in regards to the planet but additionally want a brand new laptop computer.
What are carbon offsets?
In principle, carbon offsets permit entities (companies, governments, people) to counterbalance their very own carbon emissions by paying another person to cut back emissions. There are two essential varieties of carbon offsets. One sort represents averted emissions—that’s, initiatives that theoretically stop carbon from being launched within the first place. The opposite represents carbon removals, or initiatives that draw carbon out of the environment and retailer it. However offsets are “an excellent murky world with out a complete lot of oversight,” based on Jamie Alexander, director of Drawdown Labs, a nonprofit that works with tech firms on local weather options.
“Not all offsets are created equal,” HP’s chief sustainability officer James McCall defined in an interview. Regardless of broadly agreed-upon standards for what makes offset, “the issue is that the majority offsets don’t symbolize actual emissions reductions,” mentioned Barbara Haya, director of the Berkeley Carbon Buying and selling Venture, who has studied offsets for 20 years. “So it’s actually arduous for the client of the laptop computer to understand how nicely the vendor actually vetted the mission.” Many teams are advocating for extra transparency surrounding offsets, however within the meantime, it’s each tough and time-consuming for any particular person to suss out whether or not a selected offset is value paying for.
Earlier than an organization can offset the emissions that go into making a laptop computer, first it has to measure these emissions. Tracing a product’s carbon footprint is a fancy and flawed course of, and at greatest it supplies an estimate, often reported as kilograms of carbon dioxide equivalents, or kgCO2e. We seemed by way of experiences from all the foremost laptop computer producers and located a variety of estimated carbon footprints for a typical thin-and-light laptop computer, from 161 kgCO2e as much as 334 kgCO2e. It’s higher to overestimate an object’s emissions if you happen to’re attempting to offset them, so we used the upper finish of that vary when investigating two presently obtainable offset choices provided by Lenovo and Framework.
What about Lenovo’s offset program?
At the start of 2022, Lenovo started providing offsets at checkout for a few of its thin-and-light and gaming laptops. We discovered the choice obtainable on the Yoga 7i (14″) and Yoga 9i (14″), and we confirmed through electronic mail with Claudia Contreras-Gomez, Lenovo’s government director of worldwide sustainability providers, that these $6 and $11 offsets symbolize half a ton and a ton of carbon emissions, respectively. The quantities symbolize the corporate’s greatest estimate of every mannequin’s carbon footprint, rounded as much as the closest half ton. To date, so good.
However it’s tough to inform precisely which initiatives the cash goes towards. Lenovo’s web site has a PDF flyer that lists a number of initiatives, however once we requested Contreras-Gomez for extra element, she offered hyperlinks to the wind mission in Korea, the geothermal-energy mission in Indonesia, and a biomass energy plant in Chile that wasn’t on the publicly obtainable flyer.
These offsets fall into the “averted emissions” class as a result of they purpose to stop carbon from being launched into the environment. However simply because these initiatives have the United Nations Framework Conference on Local weather Change (UNFCCC) emblem doesn’t imply they’re with out situation. The specialists we spoke with highlighted two main issues with any such offset mission: the idea of additionality and the dates when the initiatives began.
A 2016 European Fee research (PDF) discovered that 85% of all Clear Improvement Mechanism (CDM) initiatives are unlikely to be further—which implies that the overwhelming majority of these initiatives would have been constructed anyway, with out the assistance of offset cash.
The second situation is how outdated the offset credit are. As for the three particular offset initiatives Lenovo is utilizing, two had been registered in 2006 and the third was registered in 2007. The Paris Settlement prohibits international locations from utilizing offset credit from initiatives registered earlier than 2013, and CORSIA (Carbon Offsetting and Discount Scheme for Worldwide Aviation) doesn’t permit credit (PDF) from any mission that generated them previous to 2016.
There are not any guidelines saying that Lenovo can’t use these offset credit. However as CarbonPlan program affiliate Freya Chay famous in an interview, “Can you actually declare that you simply’re inflicting a brand new local weather profit if you happen to’re supporting a bit of enormous infrastructure for which the selections had been made greater than a decade in the past?” Finally, shopping for these offsets from Lenovo doesn’t offset the emissions that went into making your laptop computer, and “you won’t be making any distinction in any respect,” concluded Berkeley Carbon Buying and selling Venture’s Haya.
What about Framework’s offset program?
Framework, the corporate behind the repairable and upgradable Framework laptop computer, provides a distinct sort of carbon offset by way of Operating Tide. Not like initiatives that concentrate on avoiding emissions, like these described above, Operating Tide is a carbon dioxide removing (CDR) firm that goals to attract carbon dioxide out of the environment into floating kelp “microforests” that sink to the underside of the ocean to sequester the carbon long run. For $100, you should buy a Carbon Seize credit score by way of Operating Tide that’s roughly equal to 334 kgCO2e. However does shopping for this credit score really “[m]ake your Framework Laptop computer carbon impartial” like the corporate claims?
Scientists agree that carbon removing is “important” and that kelp sequestration is a promising possibility, although open science questions stay about this specific technique. Impartial scientists together with Tom Bell, an assistant scientist on the Woods Gap Oceanographic Establishment, labored with Ocean Visions to offer suggestions on Operating Tide’s analysis and discipline trials, and the group printed a progress report in July 2021 (PDF). “They introduced in unbiased scientific advisors, which is one thing they didn’t should do, they usually had been very receptive to our recommendation,” Bell informed us in an interview.
However Bell additionally walked us by way of the necessity for extra analysis into how a lot carbon the mission captures, how lengthy it shops the carbon, what different environmental impacts it would have on the floor and the deep ocean, and whether or not it would work at a big sufficient scale to place a dent in emissions, amongst different potential snags.1 On the analysis scale that Operating Tide is presently working, Bell defined, these points are “not an enormous deal,” however because the mission scales as much as retailer giant quantities of carbon, they “could be an enormous deal.”
Operating Tide’s kelp-sequestration mission doesn’t undergo from the identical problems with additionality because the avoided-emissions offsets we lined above. “You don’t have any purpose to be rising micro-farms that sink into the deep ocean aside from the carbon advantages,” CarbonPlan’s Chay defined, so it’s “clearly further.”
However one of many greatest open questions issues precisely measuring how a lot carbon is being faraway from the environment, how a lot will get saved when the kelp is sunk, and the way lengthy that carbon stays saved—the query of permanence. A 2021 paper that Bell co-authored used modeling to find out that carbon sequestered in kelp is saved within the ocean for tons of of years, the quantity relying closely on the place and the way deep it sinks. This technique isn’t as everlasting as different sequestration choices that may retailer carbon in rocks underground for millennia, however that know-how is even additional away.
“What Operating Tide is doing is a technique and a plan that’s value investigating additional,” Bell informed us. However as that July 2021 progress report and a newer interview with The Atlantic point out, Operating Tide remains to be working discipline trials. In line with that interview, Operating Tide estimates that it has “eliminated lower than 1,000 tons of carbon from the environment” thus far however has plans for “its largest launch ever later this yr.”
Should you spend $100 on this Carbon Seize credit score, you’re in all probability not offsetting the emissions that went into making your laptop computer. However you’re funding analysis right into a promising possibility, based on our specialists. CarbonPlan’s Chay mentioned, “After I take into consideration supporting Operating Tide, it’s far more about supporting innovation and exploration that factors in the suitable course than it’s about with the ability to obtain an ideal half ton or an ideal ton that offsets your factor.” However these offsets nonetheless aren’t the simplest factor that you simply—or firms—can do together with your cash.
What ought to firms be doing?
Along with the offsets presently obtainable from Lenovo and Framework, different laptop computer firms are contemplating comparable applications. HP’s chief sustainability officer James McCall mentioned in an interview that the corporate has run pilot applications for enterprise clients and that the choice “gained’t be too far-off” for shoppers. A Dell spokesperson informed us that the corporate “doesn’t presently use offsets on the firm stage or provide offsets to shoppers at checkout but.”
With out a number of diligence—as evidenced by our investigation into Lenovo’s and Framework’s offset applications—it’s inconceivable to know simply how efficient such offsets could be. “We shouldn’t take offsets severely in the present day,” Barbara Haya informed us. “The market is damaged, and we must always elevate an eyebrow at any claims of web carbon neutrality if offsets are used.”
And corporations shouldn’t be passing the duty of offsets to people in any respect. “Placing that duty to the patron is an issue,” mentioned Amir Jina, an environmental economist and assistant professor of public coverage on the College of Chicago. “As a result of then it’s saying that you simply, the patron, are answerable for your carbon footprint, not the manufacturing course of that we’ve chosen to interact in.” Almost each knowledgeable we spoke to mentioned that firms ought to be utilizing offsets solely as a final resort. “If we’re simply shopping for offsets and the manufacturing course of for the laptop computer stays as carbon intensive and as polluting because it presently is, then there’s no strain for these issues to alter,” mentioned Jina.
“Discount and avoidance of emissions is totally crucial factor” for firms to do first, Jamie Alexander of Drawdown Labs informed us. And after that (as outlined on this Drawdown graphic), firms “should be doing different stuff to make up for these emissions.” Alexander continued, “Emissions is just not the one factor that firms have at their disposal to do on the subject of sustainability. They will foyer for local weather coverage. They will shift their investments.”
What are you able to do as a person?
So if such offsets don’t really stability out the emissions out of your laptop computer, what are you able to do? All our specialists confused decreasing your private emissions wherever attainable. “The precedence for anybody, company or particular person or authorities, ought to be emission reductions,” CarbonPlan’s Chay informed us. “Selecting to not take a single flight goes to have a bigger impression than your laptop computer by an extended shot.” And based on the EPA’s greenhouse gasoline equivalencies calculator, a laptop computer’s lifetime emissions is roughly equal to simply 4.2% of a mean American’s house vitality use for a complete yr.
Shopping for fewer issues can also be an enormous a part of emission reductions. “As a substitute of getting a once-every-four-year replace, I’d strive a once-every-six-year replace,” Amir Jina mentioned. He additionally really helpful pushing laptop computer makers for extra repairable and upgradable choices. “The perfect factor to do could be to demand from the folks producing laptops that there be a strategy to not simply purchase this fully new piece of equipment on a regular basis.”
Past laptops, each Chay and Haya recommended electrifying your house if you happen to can. (Carbon Change has some useful guides.) “If you’ll save that $100 and electrify your house, that’s approach higher than buying random offsets or tree planting or no matter else,” Chay really helpful. Another choice, Haya mentioned, is to “take the cash that you simply need to spend on offsets and take into consideration the place you possibly can have probably the most impression with that cash.” Haya continued, “It might be supporting a non-profit, doing initiatives, or doing coverage work. It might be supporting firms which are doing demonstration initiatives of latest applied sciences.”
Chay informed us, “Carbon is just not the one lens by way of which to consider environmental good. It’s a extremely essential one, however biodiversity issues, conservation issues, social justice issues.” There is no such thing as a one resolution to local weather change—each small motion from each single individual issues.

1. Individuals have additionally raised questions regarding whether or not there are sufficient vitamins to develop that a lot kelp, in addition to the opportunity of entanglement points with creatures and with human transport, plus open regulatory questions surrounding who can do what in worldwide waters. However I digress. That is an article about laptops. How did we find yourself on this footnote about kelp?
