15Ask where and how long

Permanence and leakage

Two core integrity questions: whether a stated outcome is expected to endure and whether emissions may shift outside the assessed boundary.

Last reviewed

01CarbonBlaze explainer

Permanence asks what happens over time.

Activities can face reversal risks from fire, drought, land-use change, equipment failure, and other factors. Programs may describe monitoring, buffers, replacement rules, or other risk management; readers should ask what those measures address.

02CarbonBlaze explainer

Leakage asks what happens outside a project boundary.

A change within one area can shift pressure, production, or emissions elsewhere. Methodologies may identify and estimate this risk, but a project label alone cannot describe the full boundary.

03CarbonBlaze explainer

Risk management is not a shortcut.

Permanence and leakage should be read alongside additionality, quantification, safeguards, and tracking rather than as an automatic quality conclusion.

Common questions

Are forest-related credits always temporary?

No single answer fits all activities or programs. Readers should ask how the relevant rules address long-term risks.

Does a buffer pool remove all risk?

No. It is one risk-management approach whose design and assumptions still matter.
