A common explanation is that a feed company’s support for low-methane feed at its contracted farms is Insetting, whereas purchasing carbon credits from another region is Offsetting. This points in the right direction, but it is not sufficient. Even for the same reduction activity, the accounting and the meaning of claims differ according to who defined which value-chain boundary, which greenhouse-gas inventory reflects it, and whether separate credits were issued and transferred.
The central distinction is not inside or outside the farm, but inside or outside the reporting company’s value chain. A farm’s methane reduction may be a decrease in direct emissions for that farm and a Scope 3 supply-chain reduction for a food company that purchases its livestock products. If a company with no purchasing relationship acquires credits from the project, however, they may represent a beyond-value-chain climate contribution or an offset. The boundary differs by company even when the location is the same.
Insetting is a supply-chain activity, not an automatically recognized accounting item
Insetting is a practical term generally used for interventions that reduce emissions or increase removals within a company’s value chain. In livestock supply chains, possible activities include supporting low-methane feed, improving manure management, energy efficiency, renewable energy, improving productivity and health, and building supply-chain data systems. However, merely attaching the name Insetting does not automatically reduce a company’s Scope 3 emissions.
Under the GHG Protocol Scope 3 framework, a company assesses emissions impacts across its value chain and prioritizes reduction activities. For an actual intervention to appear in the inventory, changes must be captured by the quantities purchased, suppliers, activity data, emission factors, and calculation method. If a company continues to use an industry-average emission factor, a real improvement at a particular farm may not appear in the reported figures even though it physically occurred. This is why 1st-party data specific to the supply chain, traceable procurement quantities, and a consistent baseline matter.
Several companies within the same value chain may also describe the same outcome as their own reduction. Even if the farm, feed company, processor, distributor, and brand each contributed, the claims each may make depend on their contracts, accounting boundaries, and program rules. Describing their contributions together is different from counting the same 1 tonne in several places as an exclusive reduction or credit.
Offsetting does not end with simply buying an outcome achieved elsewhere
Offsetting generally means acquiring reduction or removal outcomes generated outside an organization’s value chain in units such as carbon credits and applying them against specified emissions. A project must satisfy rules concerning additionality, baseline, monitoring, verification, leakage, permanence, registration, and prevention of double counting. An actual emissions reduction and the issuance, transfer, and retirement of a credit are separate events.
SBTi describes mitigation beyond the value chain as BVCM, or Beyond Value Chain Mitigation. It states that companies must prioritize reductions in their own operations and value chains and that BVCM does not replace those reductions. This is an important principle that prevents the interpretation “we bought credits, so supply-chain reductions are unnecessary”. The ISO Net Zero Guidelines also provide shared terminology that distinguishes deep reductions in value-chain emissions, residual emissions, removals and offsets, and transparent claims.
Offsetting can finance high-quality projects, but it does not mean that the purchasing company’s own livestock supply chain has changed. Buying credits from an external forest project does not lower the methane intensity of its feed procurement. The supply-chain inventory and credit-use history should be presented separately so stakeholders can distinguish actual operational reductions from external contributions.
Field scenario: three claims surrounding one low-methane feed activity
Suppose food company B pays the cost of low-methane feed and measurement for contracted farm A and purchases livestock products from that farm. The first path is a value-chain reduction. If the decrease in A’s enteric-fermentation emissions is calculated using the same boundary and method, linked to the quantity actually procured by B, and captured by B’s Scope 3 calculation method, B can describe a supply-chain reduction outcome.
The second path is a project credit. If the activity is registered and verified under a recognized methodology and credits are issued, the contract must establish who owns the rights to those credits. If B sells the credits to a 3rd party while also using the same tonnes as its exclusive internal reduction outcome, a risk of double counting or misleading claims arises depending on the program rules and claim boundary.
The third path is a product claim by the feed company. The company can say that it contributed the technology, but attributing the whole reduction at farm A solely to its product requires checking the comparative design, actual intake, changes in ventilation and husbandry, measurement uncertainty, and contractual rights. Even when multiple parties participate in one activity, causal contribution, inventory reduction, credit ownership, and marketing rights remain separate questions.
Why the accounting boundary must be drawn first
The first document for an Insetting design should be a supply-chain map, not a project brochure. Map the physical product flow and contractual flow from the farm through processing and distribution to the brand, and mark the reporting company’s organizational and operational boundaries and Scope 3 categories. Also confirm whether the target livestock and feed, production period, and procured quantity can be linked. A certificate without a link to the quantity actually purchased provides weak support for inclusion in an inventory.
The baseline must represent emissions in the absence of the intervention. A simple before-and-after comparison around the introduction of low-methane feed can conflate season, animal numbers, output, and ventilation. State whether farm-specific direct measurement, emission factors, or a hybrid method was used, and whether the comparison concerns emissions per unit of product or absolute emissions. Because total emissions can rise as production increases even when emissions intensity falls, it is advisable to consider both indicators.
The GHG Protocol published its Land Sector and Removals Standard in 2026, and it is scheduled to take effect on 2027-1-1. The standard provides criteria for addressing agricultural land activities and removals in corporate inventories, but its FAQ clarifies that it is not itself a project-credit certification or verification standard. For livestock methane interventions too, it is important not to combine corporate inventory accounting and project-credit accounting in a single record.
Agree on rights and costs before carbon quantities
A supply-chain project involves at least four rights: the right to access raw data, the right to reflect outcomes in an inventory, the right to describe outcomes in marketing, and the right to hold or sell any credits issued. Ownership of a device does not automatically give a farm all four rights, nor does funding the activity automatically give a company all of them. They must be specified in a contract.
Costs must also be separated. Determine who bears the added feed cost, sensors and calibration, data communications, field records, methodology development, verification, registration, and sales costs. A project will be difficult to sustain if it presents only the market value of the reductions while excluding the farm’s operational burden and the scope of data it must provide. Risk-sharing is also needed for underperformance, sensor failure, suspended livestock operations, termination of a procurement contract, and failure to issue credits.
Claim language must match the level of evidence. “supported a low-methane feeding activity”, “reflected verified emissions reductions from a contracted supply chain in the inventory”, and “retired separately certified credits” are different claims. A pilot under measurement must not be presented as an offset already achieved, and an inventory estimate must not be called a tradable credit.
Implementation checklist
First map the reporting company’s value-chain boundary and the actual product and contractual flows.
Distinguish whether the activity belongs to Scope 1, a Scope 3 intervention, or a beyond-value-chain contribution.
Fix the baseline, target livestock, period, output, procurement quantity, and calculation method.
Confirm that 1st-party supply-chain data are actually reflected in the corporate inventory calculation.
Maintain inventory reductions and issued project credits in separate ledgers.
Contractually establish the data and claim rights of the farm, feed company, processor, and brand.
Establish procedures for holding, transferring, and retiring credits and preventing double counting.
Report both total emissions and emissions intensity per unit of product.
Specify who bears the feed, measurement, verification, registration, and operating costs.
Distinguish language about activities, reductions, contributions, and offsets according to the actual level of evidence.
Conclusion
The distinction between Insetting and Offsetting in a livestock supply chain is not determined solely by whether a project is located on a farm or in another region. Insetting is an approach that changes actual production and procurement practices within the reporting company’s value chain and connects those changes to its inventory. Offsetting is an approach that procures and uses separate reduction or removal outcomes from outside the value chain under specified units and rules.
The two approaches need not compete; they can serve different roles. Nevertheless, value-chain reductions must come first and external contributions must not replace them. Rules are also needed to separate how one outcome is claimed in inventories, credits, and marketing. A livestock project begins not with the name Insetting, but with a supply-chain boundary, 1st-party data, rights, and a contract preventing double counting. When these four elements are clear, a low-methane activity can become a credible supply-chain transition rather than merely promotional language.
