Carbon Measures Pushes Product-Level Accounting Into Climate Policy Debate

Carbon Measures, a coalition promoting product-level carbon accounting, is stepping up its engagement with policymakers and standards bodies as the debate over emissions measurement becomes more politically and commercially significant. The organization is advocating for mandatory product carbon intensity standards and a globally adopted accounting framework that would measure emissions at the level of individual products rather than relying only on corporate-level inventories.

The initiative has attracted attention because carbon accounting is increasingly becoming a foundation for climate regulation, industrial policy, trade rules, sustainable finance and procurement decisions. As governments look for ways to reward lower-carbon goods, the rules used to calculate and compare emissions could affect investment across energy, chemicals, steel, cement, transport fuels, manufacturing and consumer products.

According to Carbon Measures, it aims to accelerate innovation by developing a product-level carbon accounting framework and advocating for mandatory carbon intensity standards that create durable demand for lower-carbon products. The organisation argues that better product-level data could help markets distinguish between higher and lower-emission goods, making it easier for companies to compete on carbon performance.

Why Product-Level Accounting Is Gaining Attention

Most corporate climate reporting today is based on company-level greenhouse gas inventories, often structured around Scope 1, Scope 2 and Scope 3 emissions. Scope 1 covers direct emissions from owned or controlled sources, Scope 2 covers emissions from purchased energy, and Scope 3 covers indirect emissions across a company’s value chain.

The Greenhouse Gas Protocol remains the dominant reference point for this approach. Its Scope 3 Standard provides a methodology for companies across sectors to account for and report value chain emissions. It is widely used by companies, investors, disclosure platforms and regulators.

Carbon Measures is not arguing that value chain emissions are irrelevant. Instead, its proposal shifts more attention toward the emissions associated with specific products as they move through supply chains. This distinction matters because a company may sell multiple products with very different emissions profiles. A product-level system could, in principle, provide more precise data for buyers, regulators and customers.

For example, two producers may manufacture the same chemical, fuel, steel product or construction material with different technologies, feedstocks, electricity sources or process emissions. Product carbon intensity data could help compare those goods more directly. It could also support procurement rules, public purchasing criteria, product labels, border adjustment measures or sector-specific incentives.

The Role of the International Chamber of Commerce Panel

Carbon Measures is also linked to a wider effort to explore carbon emissions accounting systems modelled partly on financial accounting principles. The International Chamber of Commerce and Carbon Measures have convened a Technical Expert Panel on Carbon Accounting to develop principles, scope and applications for a more structured carbon accounting system.

The ICC says such a system would aim to provide accurate, transparent, verifiable and timely company-level and product-level data, while ensuring that each tonne of emissions is counted only once and attributed correctly at each step of the value chain.

That objective addresses one of the most difficult problems in climate accounting: double counting. Emissions can be reported by several actors across a supply chain, including suppliers, manufacturers, logistics providers, retailers and end users. While this can be useful for responsibility and risk management, it can also make product comparison and policy design more complex.

A ledger-style system, if widely adopted, could make it easier to trace emissions across value chains. However, it would also require significant data infrastructure, assurance practices, shared rules and cooperation among companies that may not currently have access to detailed supplier-level data.

Concerns Over Fragmentation and Comparability

The Carbon Measures proposal is emerging at a sensitive moment for climate reporting. Companies are already preparing for more demanding disclosure requirements under frameworks such as the International Sustainability Standards Board standards, the EU Corporate Sustainability Reporting Directive and other national rules.

At the same time, existing voluntary standards are being reviewed. The GHG Protocol has been working on updates to its Scope 3 accounting and reporting standard, and broader debates are continuing over market-based instruments, supplier data quality, emissions factors and how companies should reflect decarbonisation actions in their accounts.

This creates both opportunity and risk. A more granular product-level system could improve decision-making, especially for sectors where customers want lower-carbon inputs. But if new systems develop separately from existing corporate reporting frameworks, companies may face overlapping requirements, higher compliance costs and inconsistent emissions figures.

For investors, the main concern is comparability. If different frameworks produce different results for the same company or product, it becomes harder to assess transition risk, capital allocation and the credibility of net-zero strategies. For regulators, the challenge is to ensure that any new accounting approach supports real emissions reductions rather than allowing companies to select the metric that presents them most favourably.

Intensity Metrics Versus Absolute Emissions

A central issue in the debate is the difference between emissions intensity and absolute emissions. Product carbon intensity measures emissions per unit of output, such as per tonne of steel, litre of fuel or kilogram of product. This can be useful for comparing production methods and identifying more efficient or lower-carbon products.

Absolute emissions, by contrast, show the total volume of greenhouse gases released by a company, facility, sector or economy. These figures are essential for assessing whether overall climate impact is rising or falling.

Both metrics are important, but they answer different questions. A company can reduce emissions intensity while total emissions still increase if production expands. Similarly, a company with high absolute emissions may still produce some goods with lower carbon intensity than competitors.

For climate policy, this distinction is critical. Product-level standards may help create demand for cleaner goods, but they need to be linked to broader decarbonisation pathways that reduce total emissions over time. Otherwise, carbon intensity improvements could be presented as climate progress even when overall emissions remain too high.

Practical Implications for Businesses

For companies, the message is that emissions data is likely to become more detailed, more auditable and more closely connected to commercial operations. Sustainability teams will need to work more closely with procurement, finance, product development, logistics and sales teams.

Product-level carbon accounting requires more than an annual corporate inventory. It may involve tracing inputs, collecting supplier-specific data, calculating lifecycle emissions, allocating emissions across co-products, documenting assumptions and preparing figures for assurance or regulatory review.

This could be especially important for companies selling into industrial supply chains where customers are under pressure to reduce Scope 3 emissions. Buyers may increasingly ask suppliers for product carbon footprints, verified emissions intensity data and evidence of decarbonisation measures.

The issue is also relevant for exporters. As governments develop carbon-related trade rules and industrial support schemes, companies may need to demonstrate the carbon intensity of products crossing borders. Sectors such as steel, aluminium, cement, fertilisers, hydrogen, fuels and chemicals are likely to face the most immediate scrutiny.

What Policymakers Need to Consider

For policymakers, the Carbon Measures proposal raises questions about how to design rules that are credible, practical and aligned with climate goals. Product carbon intensity standards could help support markets for cleaner materials and fuels, but only if methodologies are transparent and consistent.

Key design questions include how emissions boundaries are set, how supplier data is verified, how renewable energy claims are treated, how recycled content is counted, how carbon capture is recognised, and how emissions reductions are attributed across the value chain.

There is also a governance question. Carbon accounting rules can influence market access, investment incentives and corporate reputations. That means standard-setting processes need strong safeguards, broad stakeholder participation and clear links to climate science.

A Strategic Debate for the Net-Zero Transition

The Carbon Measures initiative shows that carbon accounting is becoming a strategic policy battleground. The outcome will influence which products are recognised as lower carbon, which companies benefit from policy incentives, and how markets reward industrial decarbonisation.

For businesses, the safest approach is to prepare for both corporate-level and product-level scrutiny. Companies will still need robust Scope 1, Scope 2 and Scope 3 inventories, but they may also need product-specific emissions data that can withstand customer, investor and regulatory review.

The broader direction is clear: carbon data is moving from sustainability reports into business decisions. Whether future policy relies mainly on GHG Protocol-aligned reporting, product-level carbon ledgers or a combination of both, companies that build reliable emissions data systems early will be better placed to respond.
