Data center emissions likely 662% higher than big tech claims. Can it keep up the ruse? | Technology

Big tech has made some big claims about greenhouse gas emissions in recent years. But as the rise of artificial intelligence creates ever ******* energy demands, it’s getting hard for the industry to hide the true costs of the data centers powering the tech revolution.

According to a Guardian analysis, from 2020 to 2022 the real emissions from the “in-house” or company-owned data centers of

has been kept out of the calculation above because its differing business model makes it difficult to isolate data center-specific emissions figures for the company.

As energy demands for these data centers grow, many are worried that carbon emissions will, too. The International Energy Agency stated that data centers already accounted for

– despite all the PR and *********** that you’re seeing about their solar farms, about their electric vans – is expanding its fossil fuel use, whether it’s in data centers or whether it’s in diesel trucks.”

A misguided metric

The most important tools in this “creative accounting” when it comes to data centers are renewable energy certificates, or Recs. These are certificates that a company purchases to show it is buying renewable energy-generated electricity to match a portion of its electricity consumption – the catch, though, is that the renewable energy in question doesn’t need to be consumed by a company’s facilities. Rather, the site of production can be anywhere from one town over to an ocean away.

Recs are used to calculate “market-based” emissions, or the official emissions figures used by the firms. When Recs and offsets are left out of the equation, we get “location-based emissions” – the actual emissions generated from the area where the data is being processed.

The trend in those emissions is worrying. If these five companies were one country, the sum of their “location-based” emissions in 2022 would rank them as the 33rd highest-emitting country, behind the Philippines and above Algeria.

This is the hidden content, please

Many data center industry experts also recognize that location-based metrics are more honest than the official, market-based numbers reported.

“Location-based [accounting] gives an accurate picture of the emissions associated with the energy that’s actually being consumed to run the data center. And Uptime’s view is that it’s the right metric,” said Jay Dietrich, the research director of sustainability at

, a leading data center advisory and research organization.

Nevertheless, Greenhouse Gas (GHG) Protocol, a carbon accounting oversight body, allows Recs to be used in official reporting, though the extent to which they should be allowed ******** controversial between tech companies and has

over GHG Protocol’s rule-making process between two factions.

On one side there is the Emissions First Partnership, spearheaded by

and Meta. It aims to keep Recs in the accounting process regardless of their geographic origins. In practice, this is only a slightly ******* interpretation of what GHG Protocol already permits.

The opposing faction, headed by

has already phased out its Rec use and

aims to do the same with low-quality “unbundled” (non location-specific) Recs by 2030.

Academics and carbon management industry leaders alike are also against the GHG Protocol’s permissiveness on Recs. In an

argued that “it should be a bedrock principle of GHG accounting that no company be allowed to report a reduction in its GHG footprint for an action that results in no change in overall GHG emissions. Yet this is precisely what can happen under the guidance given the contractual/Rec-based reporting method.”

To GHG Protocol’s credit, the organization

This is the hidden content, please

to report location-based figures alongside their Rec-based figures. Despite that, no company includes both location-based and market-based metrics for all three subcategories of emissions in the bodies of their annual environmental reports.

In fact, location-based numbers are only directly reported (that is, not hidden in third-party assurance statements or in footnotes) by two companies –

This is the hidden content, please

and Meta. And those two firms only include those figures for one subtype of emissions: scope 2, or the indirect emissions companies cause by purchasing energy from utilities and large-scale generators.

In-house data centers

Scope 2 is the category that includes the majority of the emissions that come from in-house data center operations, as it concerns the emissions associated with purchased energy – mainly, electricity.

Data centers should also make up a majority of overall scope 2 emissions for each company except

, given that the other sources of scope 2 emissions for these companies stem from the electricity consumed by firms’ offices and retail spaces – operations that are relatively small and not carbon-intensive.

This is the hidden content, please

has one other carbon-intensive business vertical to account for in its scope 2 emissions: its warehouses and e-commerce logistics.

For the firms that give data center-specific data – Meta and

This is the hidden content, please

– this holds true: data centers made up 100% of Meta’s market-based (official) scope 2 emissions and 97.4% of its location-based emissions. For

This is the hidden content, please

, those numbers were 97.4% and 95.6%, respectively.

The massive differences in location-based and official scope 2 emissions numbers showcase just how carbon intensive data centers really are, and how deceptive firms’ official emissions numbers can be. Meta, for example, reports its official scope 2 emissions for 2022 as 273 metric tons CO₂ equivalent – all of that attributable to data centers. Under the location-based accounting system, that number jumps to more than 3.8m metric tons of CO₂ equivalent for data centers alone – a more than 19,000 times increase.

A similar result can be seen with

This is the hidden content, please

. The firm reported its official data center-related emissions for 2022 as 280,782 metric tons CO₂ equivalent. Under a location-based accounting method, that number jumps to 6.1m metric tons CO₂ equivalent. That’s a nearly 22 times increase.

While Meta’s reporting gap is more egregious, both firms’ location-based emissions are higher because they undercount their data center emissions specifically, with 97.4% of the gap between Meta’s location-based and official scope 2 number in 2022 being unreported data center-related emissions, and 95.55% of

’s.

Specific data center-related emissions numbers aren’t available for the rest of the firms. However, given that

and Apple have similar scope 2 business models to Meta and

This is the hidden content, please

, it is likely that the multiple on how much higher their location-based data center emissions are would be similar to the multiple on how much higher their overall location-based scope 2 emissions are.

did not provide the Guardian with location-based scope 2 figures for 2020 and 2021, so its official (and likely much lower) numbers were used for this calculation for those years.

Third-party data centers

Big tech companies also rent a large portion of their data center capacity from third-party data center operators (or “colocation” data centers). According to the

This is the hidden content, please

, large tech companies (or “hyperscalers”) represented 37% of worldwide data center capacity in 2022, with half of that capacity coming through third-party contracts. While this group includes companies other than

,

This is the hidden content, please

, Meta,

This is the hidden content, please

and Apple, it gives an idea of the extent of these firms’ activities with third-party data centers.

Those emissions should theoretically fall under scope 3, all emissions a firm is responsible for that can’t be attributed to the fuel or electricity it consumes.

This is the hidden content, please

When it comes to a big tech firm’s operations, this would encapsulate everything from the manufacturing processes of the hardware it sells (like the iPhone or Kindle) to the emissions from employees’ cars during their commutes to the office.

When it comes to data centers, scope 3 emissions include the carbon emitted from the construction of in-house data centers, as well as the carbon emitted during the manufacturing process of the equipment used inside those in-house data centers. It may also include those emissions as well as the electricity-related emissions of third-party data centers that are partnered with.

However, whether or not these emissions are fully included in reports is almost impossible to prove. “Scope 3 emissions are hugely uncertain,” said Dietrich. “This area is a mess just in terms of accounting.”

According to Dietrich, some third-party data center operators put their energy-related emissions in their own scope 2 reporting, so those who rent from them can put those emissions into their scope 3. Other third-party data center operators put energy-related emissions into their scope 3 emissions, expecting their tenants to report those emissions in their own scope 2 reporting.

Additionally, all firms use market-based metrics for these scope 3 numbers, which means third-party data center emissions are also undercounted in official figures.

Of the firms that report their location-based scope 3 emissions in the footnotes, only Apple has a large gap between its official scope 3 figure and its location-based scope 3 figure, starting in 2022.

This gap can largely be attributed to data center emissions accounting. The only change to Apple’s scope 3 methodology in 2022 was to include “work from home, third-party cloud services, electricity transmission and distribution losses, and upstream impacts from scope 1 fuels”. Since the firm listed third-party cloud services as having zero emissions under its official scope 3 reporting, that means all emissions associated with those third-party services would only show up in location-based scope 3 emissions from 2022 onwards.

2025 and beyond

Even though big tech hides these emissions, they are due to keep rising. Data centers’ electricity demand is projected to double by 2030 due to the additional load that artificial intelligence poses, according to the

Whether today’s power grids can withstand the growing energy demands of AI is uncertain.
