Understanding Carbon Credits and Offsetting

A carbon credit generally represents one metric tonne of carbon dioxide equivalent reduced, avoided, or removed under a specified programme. The credit is an accounting instrument linked to a project and methodology, not a direct reduction in the purchaser's own emissions.

Offsetting involves using credits to compensate for emissions elsewhere. Purchasing a credit and retiring it are different steps: retirement records that a credit has been used and should no longer be traded. Neither step, on its own, establishes that a broad carbon-neutral claim is justified.

Begin with an emissions inventory and a credible plan to reduce emissions within your operations and value chain. Credits should not obscure avoidable emissions or be presented as evidence that the business itself has reduced its footprint.

Report gross emissions and actual reductions separately from any credit purchases or retirements. This allows readers to understand both the business's performance and any additional climate contribution. Avoid treating all types of credits as interchangeable.

Project quality depends on more than a certification label. Additionality asks whether the claimed benefit would have happened without the crediting mechanism. Permanence considers how long a benefit lasts and the risk of reversal. Leakage examines whether activity shifts emissions elsewhere.

The baseline, monitoring approach, independent verification, and safeguards also matter. For nature-based projects, review land rights and social impacts alongside the carbon accounting. Distinguish avoided emissions from removals and consider whether the credit's characteristics fit the intended claim.

Keep records of the credits purchased, their serial numbers, the registry, and the retirement details. Document who retired them, for whose benefit, and which emissions and reporting period the intended compensation relates to.

Check that the quantity and scope of credits are consistent with the statement you intend to publish. If the underlying project or verification status changes, review the claim rather than assuming that the original purchase documentation remains sufficient.

Explain what the business has reduced, what remains, and what credits have been used for. Broad terms such as carbon neutral can leave readers with an impression that goes beyond the evidence, particularly if dependence on offsetting is not prominent.

A more specific statement about funding a project or retiring a defined quantity of credits may be easier to substantiate, but it still needs review in context. Check the rules applicable to your market and channel before publication, and make important limitations visible beside the claim.
