As an environmental attorney who spends much of my time advising business owners, I have learned an immutable truth: markets work best when the rules are clear, fair, and grounded in reality. Environmental policy is no exception. Contrary to the prevailing narrative in popular media, the global business community has not uniformly shifted away from efforts to reduce greenhouse gas emissions, and now there is a better way to track those emissions.
Bad metrics lead to bad incentives. Good metrics unlock innovation, competition, and capital. That is why the emergence of Carbon Measures, a global coalition of major businesses committed to a more accurate emissions accounting framework, deserves close attention from the business community.
Carbon Measures is calling for a new way to track greenhouse gas emissions, one that moves beyond abstract projections and toward verifiable, product level accounting in E- ledgers. The premise is straightforward but powerful: if businesses are rewarded in the marketplace for producing lower carbon products, they will invest in the technologies and processes that make those products possible. Markets, not mandates alone, can then do much of the heavy lifting.
Why the Current System Isn’t Working
The world has not monolithically pivoted away from emissions reduction. Quite the opposite. In 2026, however, emissions tracking has become a bifurcated landscape. In the United States, the federal government has dismantled or deemphasized national GHG tracking programs, relieving many businesses of what they viewed as bureaucratic and stigmatizing compliance obligations. At the same time, mandatory carbon reporting is now a strict corporate necessity for many companies operating in the European Union, California, Maryland, and other places.
Yet across the globe, there is broad agreement on one point: the current Scope 1, 2, and 3 reporting regime is not workable, particularly when it comes to Scope 3. Scope 1 (direct emissions) and Scope 2 (purchased energy) are relatively straightforward, but modest in impact. Scope 3, covering upstream (purchased goods) and downstream (use of sold products) value chain emissions and often representing up to 90% of a company’s reported footprint, is another matter entirely.
Scope 3 reporting frequently relies on guesstimations, assumptions, and generalized emissions projections that have little, if any, connection to operational reality (nothing is actually being counted). Business leaders, legal experts, and scientists alike have come to question the utility of such data. To be blunt, asking a company to precisely account for the emissions of its customers and customers’ customers is, at best, immensely challenging and, at worst, a compliance exercise untethered from meaningful emissions reduction.
The dominant methodology, the GHG Protocol, developed by the World Resources Institute decades ago (the same year Pac-Man was released in arcades), is widely used, perhaps because the problem is hard and alternatives have been scarce. But it has also been criticized for misallocating responsibility and encouraging double counting. As Exxon CEO Darren Woods, a founding member of Carbon Measures, aptly put it: holding a supplier accountable for Scope 3 emissions is “like holding McDonald’s responsible for the weight of its customers.” The calories matter, but accountability has limits. “We don’t tell McDonald’s that they can’t sell a hamburger to somebody who has a weight problem,” said Woods.
Enter Carbon Measures: A Business Led Solution
If carbon is going to be reduced, we need a better system. Carbon Measures represents an effort by businesses to propose one. Its membership includes leading companies from diverse industries and geographies, many operating large, complex supply chains. That matters because the industrial sector accounts for a significant share of global emissions and must play a central role in decarbonization.
At its core, Carbon Measures advocates for ledger based, product level carbon accounting, rooted in the same principles that govern financial accounting, now on an artificial intelligence framework. Instead of enterprise level disclosures that blur responsibility, this “cradle to gate” approach tracks emissions where they are generated and assigns them to the products being made.
Just as financial accounting requires that an asset or liability be held by only one entity at a time, a sound carbon accounting framework ensures that each tonne of carbon is counted once, accurately, and attributed to the right place. An artificial intelligence carbon e-ledger enables companies and suppliers to calculate and transfer emissions data at each step of a product’s lifecycle.
Consider a car. The emissions associated with producing and transporting each component are transferred into the emissions value of the finished vehicle. The result is a complete, nonduplicative carbon profile for that product; no gaps, no double counting.
E-ledgers Carbon Accounting is the creation of Robert S. Kaplan, Harvard Business School and Karthik Ramanna, University of Oxford.
From Accounting to Artificial Intelligence
Carbon Measures’ work goes beyond reporting. The initiative envisions product level carbon intensity standards, such as CO₂ per ton of steel or per watt of electricity. These standards are intended to be voluntary, but they have real market force. Purchasers can compare products based on carbon intensity, rewarding lower carbon options. Governments can “put their finger on the scale” by applying stricter standards in public procurement.
Over time, as technology improves, allowable emissions per unit can decline systematically, driving real reductions while still meeting demand. This approach levels the playing field, rewards innovation, and ensures that progress is measurable.
The framework itself will be developed by an independent Technical Expert Panel, co-launched with the International Chamber of Commerce. Drawing on expertise from academia, industry, financial accounting, engineering, and civil society, the AI rooted work will focus on scientific rigor and real world feasibility.
Coexisting With Existing Reporting Regimes
Critics argue that introducing any new framework risks confusion. But in practice, multiple methodologies already exist. Maryland, for example, does not rely on the GHG Protocol for its statutory “Net Direct” GHG measure. Carbon Measures is not proposing to abolish Scope 3 reporting overnight. Scope 3 may continue to play a role in voluntary disclosure, even as companies adopt ledger based product accounting for operational and market purposes.
Ultimately, a gate to gate, ledger based system can account for emissions across the full value chain, without the indeterminacy and multiple counting that plague current approaches.
What About Cost and Affordability?
Business owners rightly ask how this will affect pricing, particularly for energy and other essentials. Affordability is critical. Many lower carbon solutions cost more today. But costs decline as technology advances and markets scale. What markets need is a way to quantify both emissions and costs accurately, so capital flows to the lowest cost transition pathways.
That is what Carbon Measures seeks to enable.
As an environmental attorney, I see this initiative as a pragmatic, market aligned evolution from the current 1980 era carbon guesstimating method to a new and improved AI rooted climate policy. Better measurement will not solve climate change by itself, but without better measurement, we will continue to misallocate effort, capital, and accountability.
We will continue to write about Carbon Measures and other innovations in environmental matters.
