Carbon Insetting vs Offsetting in Corporate Spin as a Deterrent to Unified Climate Action

Insetting is the formalised term for when an organisation reduces, avoids, or removes emissions within its own operations and supply chain (WEF, 2022). Companies do this through a myriad of ways, from changing suppliers to swapping out short-haul flights for train travel.

The contrast with carbon offsetting is instructive. Offsetting is the mechanism by which an organisation balances its past or present emissions (UBE, 2025), directly funding projects around the world which reduce global emissions through reduction, avoidance, or removal. Offsetting happens outside of a company’s value chain. Insetting happens inside it. Offsetting typically involves investing in external projects, while insetting focuses on interventions within the company's value chain.

Both approaches are relevant to climate goals. To achieve net zero emissions and meet climate targets, organisations need to reduce their emissions by 50% from their baseline assessment, before cutting any residual avoidable emissions to 0% by 2050 to achieve Net Zero, all the while offsetting the emissions which do still occur. Offsetting carbon emissions is often a complementary step to insetting, helping companies address residual emissions. 

Insetting enables companies to reduce carbon emissions directly within their operations and supply chains, supporting long-term resilience and sustainability goals. Insetting and offsetting strategies can deliver multiple benefits, including positive impacts for local communities and environmental benefits beyond emissions reductions. Nature based solutions are often central to insetting projects, contributing to carbon reduction and broader sustainability strategies. Companies achieve more durable climate outcomes when they integrate insetting into their business models and strategic objectives. Climate change mitigation is a key driver for both insetting and offsetting, aligning corporate action with global sustainability goals.

Carbon insetting places the focus squarely on an organisation’s value chain: the full set of activities, suppliers, and partners that bring a product or service to market. Rather than funding a mangrove restoration project in a distant country, an insetting organisation works with its own suppliers and operations, embedding projects within its own value chains and company's supply chain to reduce the emissions embedded in what it buys, makes, and moves. Insetting projects specifically address indirect emissions (Scope 3) generated by a company's activities and operations.

Typical nature-based interventions include agroforestry on supplier farms, regenerative agriculture practices that rebuild soil carbon, watershed restoration along sourcing landscapes, biodiversity insetting, and carbon reduction projects that focus on reducing carbon dioxide emissions and enhancing carbon storage within the company's operations. Nature insetting of this kind recognises that climate and biodiversity are interlinked crises, and that value-chain action can address both at once. Insetting practices often involve stakeholder consultation and engagement with local communities to ensure positive impacts and minimize negative environmental impacts. Companies invest in insetting practices to build long term resilience into their business models and supply chains, creating time to generate positive impacts for both the environment and local communities.

This is what makes insetting structurally different from offsetting. It links an organisation’s climate commitments directly to the resources it relies on and the communities it works with. 

Both offsetting and insetting utilise the same three mechanisms: reduce, avoid, remove. And at the global level, both achieve the same thing, which is cutting emissions. The key differences lie in where that action takes place and who controls it.

Operational control.  Insetting projects sit within the company's sphere of influence. The organisation can set specifications, monitor progress, and integrate results into its procurement processes. Offset projects are managed by third parties; the purchasing company has little or no operational control over day-to-day delivery.

Proximity of benefits.  Insetting delivers co-benefits such as supplier resilience, biodiversity gains, and stronger community relationships directly within the supply chain. Offset benefits accrue elsewhere in the world, which is legitimate but more diffuse.

Reporting and accounting.  Insetting reductions typically flow through Scope 3 accounting under the GHG Protocol. Offsets are recorded as compensation rather than reduction. 

That said, the framing of insetting versus offsetting as opposing camps is one of the more damaging narratives in the sustainability space. The way we live, our food, purchased goods, and lifestyles depend on the extraction and consumption of raw materials, meaning the very industries causing the problem also need to be part of the solution. In the long run, the most effective way to restore balance is through insetting, because it directly cuts the emissions tied to how businesses operate and the resources they rely on. But change on that scale takes time, and entire supply chains cannot transform overnight. That is where offsetting plays an important role: recognising that while we are still working towards a low-carbon future, we need to act in the now, while also safeguarding against the risk of future custodians rolling back their climate commitments, and addressing historic emissions which are already damaging the planet. 

Agroforestry projects integrate trees into existing farming systems within a supplier's land. Trees sequester carbon, improve soil health, reduce erosion, and diversify farm income. For food and beverage companies with agricultural supply chains, agroforestry is often the highest-impact insetting lever available.

Regenerative agriculture interventions include cover cropping, reduced tillage, composting, and rotational grazing. These practices rebuild soil organic matter, one of the largest potential carbon sinks on the planet, while also reducing fertiliser inputs and their associated emissions. Regenerative agriculture is also a primary vehicle for biodiversity insetting, as restored soil ecosystems support insect, bird, and plant diversity.

Energy-efficiency upgrades on-site cover a wide range, from LED lighting and heat-recovery systems at supplier facilities to electrification of machinery and on-site renewables. Because these interventions reduce energy consumption, they cut Scope 3 emissions for the buying company while reducing operational costs for the supplier.

Landscape restoration initiatives such as wetland and forest restoration address emissions at a landscape scale, often involving multiple suppliers and sometimes coordinated with government or NGO partners. Carbon sequestration examples at this level include the restoration of peatlands, among the most carbon-dense ecosystems on Earth, which can lock in centuries of stored carbon while providing flood protection and habitat for rare species. 

For most companies, Scope 3 emissions, those embedded in the supply chain and in the use of sold products, make up the majority of their total carbon footprint. Insetting directly addresses this by changing the activities that generate those emissions in the first place, rather than compensating for them after the fact.

Life-cycle emissions accounting is the methodological backbone of insetting. By mapping the full emissions profile of key products from raw material through to end of life, organisations can identify the largest hotspots and design interventions that address them at source. This also enables transparent communication of progress to investors, customers, and regulators, all of whom are applying increasing scrutiny to supply chain claims.

Double counting is a genuine risk, particularly where insetting projects generate carbon credits that are also claimed by the host country or another buyer. Robust project design must include clear attribution rules from the outset, verified against recognised standards such as the GHG Protocol Scope 3 standard or the relevant ISO frameworks.

Well-designed insetting programmes have demonstrated emissions reductions of 20-40% in targeted supply chain segments within five years, depending on the starting baseline and the ambition of interventions chosen.

Deciding on certification standards early is critical. The choice of standard, whether Verra's VCS, Gold Standard, ICROA-endorsed programmes, or sector-specific frameworks, shapes what data you must collect, how projects are structured, and what claims you can make publicly.

Robust MRV systems should be built into the project from day one. This means defining the monitoring protocol, agreeing data-collection responsibilities with suppliers, and scheduling independent verification before any emissions reductions are reported or credited.

Insetting organisations also face a decision about whether to issue carbon credits from their projects. Some choose to retire credits internally and use them to support corporate claims; others participate in voluntary carbon markets to generate revenue that funds further activity. This is where third-party audit and verification services come in. Assessment via ISO 14064-1:2018, ISO 14067:2018, and the GHG Protocol gives organisations the assurance of measuring what matters now and in the future, while mitigating past, present, and future impact on the planet through verified, auditable emissions management.

Science-Based Targets (SBTs) require companies to demonstrate genuine emissions reductions in line with the Paris Agreement, not simply to compensate for ongoing pollution. Insetting, as a value-chain reduction mechanism, maps directly onto this requirement. Offsetting alone cannot substitute for the deep decarbonisation that SBTs demand.

The priority order matters: insetting should come before purchasing offsets. This is both a credibility issue and a strategic one. Stakeholders and regulators increasingly scrutinise companies that offset heavily without evidence of supply-chain action. More fundamentally, insetting builds durable, structural change, while offsets remain vulnerable to policy shifts and the rolling back of commitments, something we have already seen from organisations including the Net Zero Banking Alliance and several leading consumer goods companies.

Embedding insetting into a net zero roadmap means treating it as a core capital and procurement decision, with multi-year timelines, defined milestones, and transparent reporting. Not a communications exercise.

Insetting requires upfront investment in project design, supplier engagement, data systems, and verification. These costs are real and should be budgeted honestly. The long-term savings from reduced energy use, lower raw material consumption, improved supplier resilience, and avoided regulatory risk frequently outweigh the initial outlay over a five-to-ten year horizon, but only if the programme is designed well from the start.

Carbon credits generated by insetting projects can create a revenue stream or reduce the cost of compliance in carbon-priced jurisdictions. However, carbon credit prices are volatile and should not be the primary financial justification for a programme. The stronger business case rests on supply chain resilience and future-proofing against tightening regulation.

Supplier incentive structures remain an underused tool. Premium prices, extended contract terms, co-investment in equipment, and technical assistance can all be deployed to encourage supplier participation and share the financial burden of transition fairly along the value chain.

Carbon ownership and rights must be clarified in project agreements before any work begins. Who owns the carbon sequestered on a supplier's land? Who can issue or retire credits from it? Ambiguity here creates legal risk and can seriously damage supplier relationships.

Free, prior, and informed consent (FPIC) from affected communities is not optional. It is an ethical and, in many jurisdictions, a legal requirement. Landscape-scale insetting projects in particular must invest genuine time in community consultation and ensure that local people share in the benefits, not just in the risk.

Permanence safeguards, including buffer pools, long-term land-use agreements, and insurance mechanisms, protect against the risk that sequestered carbon is re-released through fire, disease, or land-use change. Any credible insetting programme must address permanence explicitly in its project design.

Understanding insetting in practice also requires understanding of why these concepts have become so contested in the first place. Despite the surge in those working in sustainability, this influx of talent has unintentionally deepened divides, with many unknowingly, and some knowingly, feeding anti-sustainability narratives. The sustainability world has become a war of words. While thousands pursue carbon literacy, definitions are blurring, often obscured further by new entrants eager to set standards and disrupt the status quo.

This confusion has proven fertile ground for high emitters. Through careful PR framing, terms like net zero, carbon neutral, offsetting, and insetting are often twisted into catchphrases that sound good but say little. The outcome is public paralysis: a population unsure of who to trust, and policymakers reluctant to act boldly for fear of being accused of 'greenwashing' or 'greenhushing'.

We can see this in the failure to reach consensus on international agreements like the UN plastics treaty and the treaty on shipping-related emissions, where corporate lobbying and semantic ambiguity diluted ambition. By sowing confusion and division, large emitters successfully delay systemic change while continuing business as usual.

The uncomfortable truth is that, globally, climate literacy remains low, with this gap in understanding leaving space for confusion, misinformation, and corporate spin. Nowhere is this clearer than in the ongoing debate between offsetting and insetting, two ideas that should complement one another, yet are often pitched as competing opposites. The way forward is not to abandon either approach, but to build a shared language around them. Both offsetting and insetting are tools, and tools are only as useful as those who wield them. If we want unified action, we must start by unifying understanding. That begins with climate literacy, the foundation of any lasting, collective effort to turn the tide.
