Carbon offset
Definition
A carbon offset is the use of carbon credits or equivalent units to compensate for emissions that remain within a defined claim boundary.

Overview
What it means in practice
Carbon offset should be read as a decision term, not simply as a label. Its practical meaning depends on the boundary being assessed, the accounting or governance purpose, and the evidence used to support the claim.
In practice, users should ask what is being measured or governed, who is relying on the term, and what would change if the term were applied differently. That discipline keeps carbon offset from becoming a shorthand that hides assumptions.
Why it matters
Carbon-market terminology can create a false sense of precision when units, claims and accounting boundaries are not separated. Carbon offset matters because it affects whether a climate claim is traceable, exclusive and proportionate to the evidence behind it.
Common misconception
A common error is to treat carbon offset as proof of climate benefit by itself. The stronger approach is to identify the programme rules, accounting boundary, ownership trail and claim being made.
Review questions
What boundary does the term cover? What evidence would prove or narrow the claim? Who could reasonably misunderstand the term if the context is not stated?
How it is used
In professional practice, “Carbon offset” helps governments, companies, investors and technical teams describe or assess the use of carbon credits or equivalent units to compensate for emissions that remain within a defined claim boundary. It is commonly encountered in climate strategies, transition plans, emissions inventories, scenarios and investment decisions.
A credible application identifies the relevant methodology, emissions boundary, baseline, timeframe and underlying data.
