Definition
Fugitive emissions are unintended or irregular releases of gases or vapours from equipment, systems, storage or extraction activities.

Overview
What it means in practice
Fugitive emissions should be read as an energy-transition term. Its meaning depends on the technology, market, contract, grid boundary and emissions-accounting method.
In practice, users should state the boundary, method, instrument and evidence. That keeps fugitive emissions specific enough for review without turning it into a broader claim.
Why it matters
Fugitive emissions matters because energy language can mix physical supply, contractual instruments, timing and emissions claims. Clear boundaries help readers understand what is actually being changed or evidenced.
Common misconception
A common error is to use Fugitive emissions without stating the system boundary or calculation method. Those details often determine the meaning of the claim.
Review questions
What instrument, boundary or method gives the term meaning? What evidence supports it? What limitation would change how a reader interprets the claim?
How it is used
Governments, companies, investors and technical teams use “Fugitive emissions” in climate strategies, transition plans, emissions inventories, scenarios and investment decisions. In each case, the user should state the relevant methodology, emissions boundary, baseline, timeframe and underlying data; otherwise, the same term may be applied to materially different situations.
In this context, it refers to unintended or irregular releases of gases or vapours from equipment, systems, storage or extraction activities.
