Carbon insetting vs. offsetting: a guide for businesses

4 min readLast updated 6 August 2026

Direct answer

Carbon insetting is reducing or capturing CO2 within your own value chain, for example at your suppliers or in your own production. Offsetting is compensating for emissions outside your chain, by buying credits elsewhere for a forest or a wind farm. The difference decides whether you may claim a reduction or only a contribution.

Carbon insetting vs. offsetting: scattered information versus Energy Intelligence

More and more companies want to show that they are tackling their emissions. A transport firm buys forest projects in South America, a food producer helps its own farmers use less fertiliser. Both are called climate action, but the rules differ sharply. The Dutch regulator ACM and international standards look closely at the difference between compensating outside your chain and reducing within it. Companies that confuse the two risk a misleading claim and reputational damage.

  • Insetting counts in your own CO2 accounts (scope 1, 2 and 3); offsetting sits in a separate administration and does not count as a reduction of your emissions.
  • The Dutch regulator ACM does not simply allow absolute claims such as climate neutral or CO2 neutral based on compensation; vague compensation terms are quickly misleading.
  • The Science Based Targets initiative does not accept buying credits outside the chain as a substitute for reduction; that reduction must come from within your chain.

Insight

Traditional approach

Information is scattered across portals, documents, invoices or separate spreadsheets.

Modern approach

Data, context and interpretation are brought together into a clear decision picture.

Decision-making

Traditional approach

Choices are made based on averages, assumptions or occasional analyses.

Modern approach

Scenarios, KPIs and current measurement data make the trade-off more concrete and repeatable.

Follow-up

Traditional approach

Actions often stay non-committal or disappear into separate reports.

Modern approach

Follow-up actions, monitoring and reporting are linked to the same energy data.

What is the difference between insetting and offsetting?

Offsetting is compensation outside your own value chain. You buy carbon credits from a project that reduces or captures CO2 elsewhere, such as tree planting or a wind farm, and use those credits to compensate for your own emissions. Under the standards, those credits sit in a separate administration, apart from your own CO2 accounts. Insetting works within your own chain. You reduce or capture CO2 in activities you influence yourself: your production, your transport, your suppliers or your raw materials. Consider a food company that helps growers in its chain switch to farming with lower emissions. That reduction counts in your own scope 1, 2 or 3, because the emissions in your chain actually fall.

  • Offsetting: buying credits for CO2 reduction or capture outside your chain.
  • Insetting: reduction or capture within your own production, transport or suppliers.
  • Insetting lowers the emissions in your scope 1, 2 or 3; an offset does not.
  • With insetting you steer the source yourself; with offsetting you pay an external party.

Why does the distinction matter for your claims?

The distinction decides what you may and may not say. The Science Based Targets initiative bases reduction goals on CO2 accounting under the GHG Protocol. Buying credits outside your chain does not count there as a reduction of your emissions; at most it is an additional contribution alongside your own reduction, not a substitute. The ACM is equally strict on the consumer side. Research by the ACM shows that fewer than half of consumers see the difference between CO2 reduction and CO2 compensation. Vague terms such as climate neutral and CO2 neutral based on compensation are therefore quickly misleading. The ACM advises companies to avoid such absolute claims and to substantiate every claim concretely and with facts.

  • Standards do not count offsets as a reduction of your own emissions.
  • An insetting reduction may be presented as your own CO2 reduction, if measured.
  • The ACM warns against absolute claims such as climate neutral based on compensation.
  • Every sustainability claim must be correct, clear, specific and backed by facts.

When do you choose which, and what are the pitfalls?

The order that Milieu Centraal follows is useful: first prevent and reduce, only then compensate. Insetting belongs to that first step. You map your own emissions and tackle the largest sources in your chain. Offsetting only fits afterwards, for emissions you cannot yet avoid, and then as a contribution, not as a final verdict. The biggest pitfall is presenting compensation as if it were reduction. A second pitfall is an unproven offset: if you buy a credit without verifiable, lasting and not double counted CO2 gains, your claim is fragile. The EU is also tightening the rules with legislation that limits vague climate claims. So document what you reduce within your chain and what you contribute outside it, and keep the two separate.

  • Follow the order: first prevent and reduce, only then compensate.
  • Use insetting for sources in your own chain that you can influence.
  • Use offsetting only as an additional contribution for unavoidable emissions.
  • Keep insetting and offsetting strictly separate in your reporting and claims.
