A Fight Over Big Tech’s Emissions Has the Greenhouse Gas Protocol Caught in the Crossfire
The recent request for public comment from the Greenhouse Gas Protocol (GHGP), issued last week, might appear to the casual observer as a mere procedural step, perhaps even clerical. Yet, for technology titans Google and Microsoft, this announcement marks a pivotal triumph in a protracted, multi-year conflict against their industry rivals over the contentious issue of accurately accounting for the carbon emissions generated by their burgeoning data centers and, by extension, the energy-intensive demands of artificial intelligence.
This development signals that the GHGP, a globally recognized authority in carbon accounting standards, is moving closer to mandating an hourly accounting methodology for electricity emissions. This specific carbon-accounting system has been vigorously championed by Google since 2020 and Microsoft since 2021, becoming a cornerstone of their respective climate commitments. Google’s spokesperson, Mara Harris, articulated the company’s position, stating, “We support the proposed Scope 2 updates, which would increase the accuracy and the decarbonization impact of carbon inventories.” Microsoft, maintaining a more reserved stance, declined to offer a comment on the matter.
While Google celebrates this strategic advancement by the GHGP, the intricate and often contentious path to this point has not been without its critics. Even stakeholders who typically align with Google’s preferred carbon-accounting methodology acknowledge the intensity of the struggle. Jesse Jenkins, an associate professor at Princeton University and the director of the Google-funded ZERO (Zero-Carbon Energy Systems Research and Optimization) Laboratory, candidly remarked, “There’s an intensive lobbying effort going on here, one that these major corporations have each staked considerable reputation and money into, and they are getting a bit ugly.” This observation underscores the high stakes and fierce competition that characterize the efforts of tech giants to shape the future of emissions reporting, which has profound implications for their public image, regulatory compliance, and bottom lines.
Deciphering Scope 2: The Core of the Conflict
The crux of this intricate battle lies within Scope 2, a critical subcategory defined by the GHGP for reporting a company’s indirect emissions. These emissions primarily arise from the generation of purchased electricity, steam, heat, or cooling. For the behemoths of the tech world, Scope 2 emissions have witnessed an alarming surge, directly attributable to the explosive growth of artificial intelligence and its insatiable demand for energy to power vast networks of data centers. As these energy loads continue to escalate at an unprecedented rate, so too has the imperative to establish a more precise and impactful method for their accounting.
Recognizing this urgent need, the GHGP announced its intention to overhaul its Scope 2 accounting standards in late 2022. This ambitious undertaking was further bolstered by a significant infusion of capital—a $9.25 million grant from the Bezos Earth Fund. This financial backing elevated the debate from academic white papers into a tangible, real-world process, with the formation of a GHGP-sponsored “working group” tasked with meticulously hammering out the specifics of the new, revised standards. However, from the outset, some observers and participants felt that the playing field was far from level. One member of the working group, who supports an alternative Scope 2 accounting approach known as “emissions first” and was granted anonymity to speak freely, expressed a sentiment of disillusionment: “Our understanding was that we would have an arena for ideas to go back and forth. It seemed like [from the beginning] it was pretty well-baked where it was going to go.” This statement hints at an underlying perception that the direction of the new standards was predetermined, favoring certain powerful corporate interests.
The Rival Philosophies: Hourly Matching vs. Emissions First
The “emissions-first” contingent represents a broad coalition, including the Emissions First Partnership, an influential group founded by Amazon, Meta, and Salesforce. This camp advocates for an accounting philosophy centered on maximizing annual emission reductions by strategically swapping renewable energy certificates (RECs), even if the clean power they represent is generated and purchased far from where the actual energy consumption occurs. Within this broader approach lies a more refined methodology known as “emissionality,” or the “marginal emissions” method. This stricter variant aims to introduce more stringent rules, ranking RECs based on their marginal emissions benefit, thereby ensuring that they genuinely support the development of new, impactful clean energy projects. While the Emissions First Partnership declined to comment, and Salesforce did not respond to requests, their collective advocacy highlights a fundamental divergence in how corporations approach their decarbonization strategies.
This emissions-first approach stands in stark contrast to the hourly accounting method, which is the preferred standard of Google and, to a slightly lesser extent, Microsoft. Google has integrated this rigorous standard into its ambitious “24/7 Carbon Free Energy by 2030” goal, while Microsoft pursues a similar vision with its “100/100/0 by 2030” commitment. The core principle of this method is to meticulously match every hour of electricity consumption from a company’s facilities—primarily its data centers—with an equivalent amount of new, carbon-free power. Crucially, this clean energy is ideally produced locally and in real-time, with the ultimate objective of achieving around-the-clock clean energy operations. Proponents argue that this method offers a far more accurate representation of a company’s true carbon footprint and directly incentivizes the deployment of clean energy precisely when and where it is needed most.
The War of White Papers and Working Group Dynamics
The intensity of this debate is further evidenced by the considerable resources that Amazon, Google, Meta, and Microsoft have poured into advancing their respective accounting methodologies. A recent report by the climate nonprofit InfluenceMap reveals a veritable “war of white papers”: over 25 major studies on emissions accounting have been published since October 2017. More specifically, since the GHGP Scope 2 revision process officially commenced in November 2022, at least 13 pieces of corporate-sponsored research have emerged. Of these, Google has sponsored seven, Meta three, Amazon two, and Meta and Microsoft have co-sponsored one. This intellectual arms race underscores the profound financial and reputational stakes involved, as each company seeks to legitimize its preferred approach through scientific and academic backing.
Despite this seemingly balanced academic output, critics argue that the GHGP’s working group, established to revise the Scope 2 accounting standards, lacked ideological equilibrium from its inception. Out of its 45 members, there was notably no direct representation from key players in the emissions-first camp, namely Meta, Amazon, and Salesforce. This perceived imbalance was so significant that the Emissions First Partnership felt compelled to lobby the GHGP for the belated inclusion of a representative from Heineken, an Emissions First Partnership member, who eventually joined in March 2025, in an attempt to introduce a semblance of balance to the working group’s composition.
In response to concerns about representation, David Burns, GHGP’s director of governance, stated to WIRED: “Following the close of our rolling application window in early 2025, we conducted a gap assessment to address any perceived gaps raised by the Independent Standards Board and stakeholders. Based on this review, the Independent Standards Board appointed additional members across all five Technical Working Groups in February and March 2025.” He further asserted, “While we will always consider stakeholder views sent via our formal communications channels, no company or coalition has any role in our decision-making, including appointments to technical working groups.” However, the fact remains that Google and Microsoft had direct representatives within the group, as did organizations such as Energy Tag, a nonprofit that has received grant funding from Google. Energy Tag did not respond to requests for comment, leaving questions about potential influence unanswered. Google, through its spokesperson Mara Harris, reiterated its support for “the continued development of credible metrics to estimate and credit the avoided emissions from carbon-free electricity procurement outside of a company’s carbon inventory,” a statement that theoretically could encompass the marginal impact method.
The "Goldilocks" Strategy and a Controversial Reversal
Despite the persistent accusations of bias within the working group, it did manage to forge ahead with what was termed a “Goldilocks” strategy, aiming to accommodate both mandatory hourly matching and an emissionality method. In June, the group voted on this hybrid approach, ultimately deciding to advance both methodologies to public comment. However, a significant controversy erupted when the latter half of this proposal—the emissions-first element, specifically the “marginal impact method” (MIM)—was essentially rejected by the GHGP’s International Standards Board (ISB). In a decision made at the end of July, the ISB declared that despite receiving majority support from the working group, the marginal impact method required “further foundational development” before it could proceed to public comment.
Yet, by the time the formal public consultation was launched in October, the ISB appeared to have reversed its earlier decision. The hourly accounting proposal was sent to formal public comment, while the marginal emissions proposal was advanced to an intermediate public comment step, intended to inform further refining work. The precise reasoning behind this reversal remains shrouded in ambiguity. Internal pressure from the Scope 2 working group itself certainly played a role. Nearly a dozen members, representing diverse ideological viewpoints, signed a private letter in August, reviewed by WIRED, addressed to the International Standards Board. This letter urged the board to reconsider its decision to put the emissions-first approach on hold and instead release it for comment alongside the hourly matching provision. “We recommend meeting in early September to ensure we have the appropriate time to respond to feedback,” the letter stated. One signatory confirmed that no such meeting took place, though the GHGP reportedly received substantial pushback through formal complaint channels regarding the deferment of the emissions-first approach. When pressed by WIRED on whether the letter or external pressure influenced the ISB’s reversal, GHGP spokesperson Alison Cinnamond responded evasively, stating, “We did not move the full MIM proposal to public consultation. We did advance questions on consequential accounting that are relevant to MIM. The ISB also did not override any previous decision.” This carefully worded response does little to dispel the perception of a behind-the-scenes struggle.
An Unstable Truce and Mounting Threats to GHGP
It might be tempting to conclude that advocates for both hourly accounting and the emissions-first camp have achieved their objectives, given that both methodologies have advanced to some form of public comment. However, emissions-first proponents argue that the marginal emissions proposal sent to public comment is a “watered down” version of what was originally proposed to the Scope 2 working group. Adding to their frustration, the marginal emissions approach has been effectively demoted from the high-profile Scope 2 working group. Any further development on this critical topic will now be channeled through the Actions and Market Instruments (AMI) working group. This particular group experienced a significant four-month hiatus in meetings between May and September of this year, a lapse attributed to the departure of two key employees and ongoing funding challenges. According to a source familiar with the situation, advocates for the marginal impact method from the Scope 2 working group were conspicuously absent from both the September meeting, where MIM was discussed, and the subsequent October meeting.
GHGP spokesperson Alison Cinnamond maintained that “The process followed was exactly as outlined in GHG Protocol’s published workplans,” adding that the marginal impact method was not covered at all at the October meeting. She further stated that the Scope 2 working group would have future opportunities to engage with the work of the AMI group, but noted that “specific next steps for that engagement are still being determined.” For many emissions-first-oriented players, this arrangement is deemed insufficient. The very prospect that some actors will face a mandatory hourly matching requirement has reportedly driven some companies, both tech and non-tech, to contemplate drastic measures, with rumors circulating of them considering abandoning the GHGP altogether.
In a seemingly related development, just one day after the Scope 2 public comment announcement, a rival carbon-accounting coalition named Carbon Measures was launched. This new platform boasts major Fortune 500 companies among its members, including Exxon Mobil and Air Liquide. Notably, none of the listed corporate members appear to belong to the Emissions First Partnership. Shea Agnew, a spokesperson for Carbon Measures, asserted that the platform’s launch had been in development for several months and bore no relation to the ongoing developments at the GHGP. When asked if their companies were among those considering leaving the GHGP, both Amazon and Meta declined to comment, although a source familiar with their strategies indicated no immediate plans to depart the organization.
Beyond the specter of member defections, which directly threatens the GHGP’s revered status as a near-universal standard-setter in the carbon-accounting market, the organization faces another profound existential challenge: severe funding issues. A source with intimate knowledge of the GHGP’s financial situation claims that the aforementioned $9.25 million grant from the Bezos Earth Fund has already run dry, despite the nonprofit still being listed as a current funder on the GHGP’s website. The Bezos Earth Fund did not respond to a request for comment. Raising new funds is proving to be an arduous task. Companies are increasingly demanding a clearer return on investment from their contributions to the GHGP, particularly as climate-related work in the private sector comes under heightened scrutiny, especially from a potentially less climate-friendly administration.
“The Greenhouse Gas Protocol is definitely in a bit of a financial bind. No one wants to support them because they can’t have their name associated with it, but they depend on philanthropic and corporate money to run. And they’re going in a direction that a lot of companies don’t like the outcome of,” stated a source deeply familiar with the GHGP’s funding landscape. This confluence of instability—financial precarity and internal dissent—arrives at a particularly inopportune moment for the organization. Not only are regulatory frameworks in the European Union and California actively codifying GHGP’s standards into law, thereby institutionalizing its methodologies, but the GHGP is also forging a new strategic partnership with the International Organization for Standardization (ISO). This collaboration aims to further “harmonize” the two organizations’ various carbon-accounting standards, a move that, while potentially beneficial for global consistency, must navigate the turbulent waters of internal disagreement and external pressure that currently define the GHGP’s precarious position.
