GHG Protocol raises the bar for biofuels accounting with new land, combustion and traceability rules

The Greenhouse Gas Protocol’s new Land Sector and Removals Standard is likely to change how companies frame biofuels in corporate carbon reporting. Taking effect on 1 January 2027, the standard applies to agriculture and CO2 removal technologies, but not yet to forestry.

The Greenhouse Gas Protocol’s new Land Sector and Removals Standard is likely to change how companies frame biofuels in corporate carbon reporting. Taking effect on 1 January 2027, the standard applies to agriculture and CO2 removal technologies, but not yet to forestry. That matters immediately for crop-based biofuels and agricultural residue pathways, and it matters indirectly for forest-derived bioenergy because the protocol has still not settled a comprehensive corporate accounting framework for forestry.

The most important shift is conceptual. The standard states plainly that biogenic product CO2 emissions are not zero and that biogenic products cannot be assumed to be carbon neutral. Biomass combustion, it says, releases CO2 at rates comparable to fossil fuels on an energy basis, which means companies that purchase, consume or sell non-food, non-feed biogenic products, including biofuels, must account for CO2 emissions at the point of oxidation using emission factors by fuel or material type. They must also account for associated CH4 and N2O emissions from combustion, decomposition or other end uses.

That does not mean the protocol treats all biofuels as equivalent to fossil fuels. It means the accounting treatment now depends on what sits behind the fuel. Requirement 17 creates two reporting pathways. If a company reports the full life-cycle GHG profile of the biogenic product, including annual net land carbon stock changes, and also accounts for land use and land carbon leakage where required, then biogenic product CO2 can be reported separately under gross CO2 fluxes. If it does not meet those conditions, the same CO2 is reported inside the physical GHG inventory under land emissions. In practical terms, the protocol now gives the cleaner reporting treatment only to companies that can support a fuller land-based accounting case.

For biofuels, the significance of that change is that combustion is no longer the whole story, and “biogenic” no longer carries a built-in presumption of neutrality. The standard requires companies to report not only biogenic product emissions, but also land use change emissions, land management net biogenic CO2 emissions, land management production emissions, land occupation and land carbon leakage where applicable. It also requires scope 3 minimum-boundary coverage for product life-cycle emissions associated with agricultural products and bioenergy feedstocks, including related inputs such as fertilisers, pesticides and herbicides. For bioenergy consumed by the reporting company, those upstream life-cycle emissions, land use and leakage are reported in scope 3 category 3.

This matters most for crop-based pathways

Because the standard embeds land use change far more deeply into inventory accounting. Requirement 10 requires companies to account for land use change emissions from CO2, CH4 and N2O, based on total land carbon stock decreases across aboveground biomass, belowground biomass, dead organic matter and soils. For annual crops and other land-based products with cultivation cycles of 20 years or less, the land use change assessment period is 20 years. Those emissions are then allocated across the assessment period using linear discounting, which places more weight on production closer to the original land conversion event. Where companies have complete land management unit traceability they are steered towards direct land use change accounting. Where traceability is weaker, the protocol allows jurisdictional direct land use change or statistical land use change approaches, but with stated hierarchy and conditions.

The treatment of leakage is just as important. Chapter 8 makes land occupation a required metric, measured in hectares, for scope 1 and scope 3 agricultural land use. It also requires companies to quantify land carbon leakage when high-leakage-risk activities occur. The protocol explicitly lists the use of food or other agricultural products for non-food, non-feed purposes, including crop-based biofuels and bio-based feedstocks, as one of those high-risk activities. Leakage is to be quantified using a carbon opportunity cost approach, which estimates the annualised carbon stock losses from converting native ecosystems to agricultural land to replace displaced food or feed production. In other words, the standard brings the food-versus-fuel question into the inventory architecture itself rather than leaving it as a side debate in methodology papers.

The protocol also encourages companies to go beyond simple hectare reporting. It recommends disaggregating land occupation by land type and separately quantifying the carbon opportunity cost of land use. That is especially relevant for biofuels because equal land areas are not climate-equal. A hectare of expansion in a low-carbon landscape and a hectare in a carbon-rich landscape can imply very different climate impacts, and the protocol is pushing reporting in that direction.

Traceability is another major tightening point.

The standard sets out explicit spatial boundaries for scope 3 accounting, ranging from global and jurisdictional sourcing to sourcing region, land management unit and harvested area. The more specific the traceability, the more specific the accounting can become. To claim physical traceability at sourcing region, LMU or harvested area level, companies must use accepted chain-of-custody models such as identity preservation, segregation, controlled blending, or certain mass-balance systems in which the relevant specified characteristics are known, proportionate and reconciled over a defined period. Book-and-claim systems do not qualify as physical traceability. Nor do mass-balance systems where volumes are unknown, non-proportional allocation is used, or mixing occurs across multiple countries or sourcing regions without meeting the specified rules. For biofuel markets where certificate-based systems are common, that could become a significant dividing line between what can support physical inventory claims and what may need to be reported separately.

The standard’s treatment of waste-based pathways is more favourable, though still conditional. In its allocation guidance, it says waste with no market value should not carry upstream emissions, removals or other metrics from the system that produced it prior to the point it became waste. It also allows companies to apply the recycled content allocation method to post-consumer waste that is recycled or reused, explicitly naming used cooking oil and recovered fibre as examples. That is a meaningful advantage for waste-based biofuels because it reinforces the long-standing logic that upstream agricultural burdens should not automatically be loaded onto post-consumer wastes. Even so, companies still need to disclose evidence that the material is genuinely post-consumer waste and has been reused or recycled, and they still need to report downstream combustion and any applicable land-related impacts consistently with the standard.

The protocol also has clear consequences for BECCS-style claims. It allows captured biogenic CO2 with geologic storage to be reported as a removals category, but only if strict conditions are met. Companies must account for all cradle-to-grave life-cycle emissions across the geologic storage pathway. They must have physical traceability to the entity capturing the CO2 and to the injection site or storage hub. They must use data specific to the injection site, reservoir and CO2 inputs, provide quantitative uncertainty estimates, and maintain ongoing monitoring to detect storage losses. For agricultural biomass specifically, Requirement 25 says companies must account for all life-cycle GHG emissions, land use and land carbon leakage from the land the biomass came from, including land use change emissions, annual net land carbon stock change and land management production emissions. They must also demonstrate that land use change emissions are not significant. The standard sets a quantitative test for that: if less than 5% of the sourcing area has experienced land use change, the criterion is met. If there are still non-significant land use change emissions attributable to the biomass, those emissions must be subtracted from the CO2 or carbon counted towards geologic storage.

That will matter in practice because it narrows the room for presenting BECCS as a simple add-on to existing bioenergy systems. Under this standard, the integrity of a BECCS claim depends not only on capture and storage performance but also on the land profile of the underlying biomass. A weak feedstock sourcing case can directly reduce the removals a company is able to report.

There is also a reporting consequence that should not be overlooked. The protocol requires disaggregated reporting by accounting subcategory, scope and scope 3 category. Additional accounting categories such as land use, land carbon leakage, gross CO2 fluxes, product carbon storage and reversals must be reported separately from the physical GHG inventory. Companies cannot simply net everything together and present a single simplified number. If they choose to report aggregate values, they must do so under additional reporting rules and still include, at a minimum, fossil and industrial emissions, land emissions, biogenic product emissions and land carbon leakage. That architecture makes it harder to obscure the trade-offs between combustion emissions, feedstock land-use effects and any removals claims.

For the biofuels industry, the commercial implications are likely to be uneven. Companies with stronger physical traceability, better primary data, more robust land-use-change screening and a heavier reliance on waste-based feedstocks may find the new standard strengthens their comparative position. Companies relying on generic emissions factors, broad country averages, weak chain-of-custody systems or simplistic carbon-neutrality narratives are likely to face a tougher evidentiary test. Crop-based fuel pathways are not ruled out, but they are moved into a more demanding accounting environment in which land demand, land conversion risk and displaced production are much harder to ignore.

There is one important boundary to keep in view. This is an accounting standard, not a fuel standard, not a certification scheme and not a regulation that directly decides market access. It does not itself determine whether a litre of SAF, ethanol, biodiesel or renewable diesel qualifies under any one policy regime. It also does not yet provide a complete answer for forestry-based pathways. But accounting standards shape what companies can credibly disclose, how investors and auditors assess those disclosures, and what regulators or voluntary programmes may later choose to borrow. On that basis, the direction of travel is clear. The new GHG Protocol standard does not end the debate over biofuels, but it does make future claims more dependent on traceable feedstocks, defensible land accounting and a fuller picture of what happens beyond the stack or tailpipe.
