What happens when a carbon project stops being monitored?

27 September 2026

When a carbon project stops being monitored, its credits lose their validity, the registry suspends or cancels the project, and any tokenised credits linked to it become worthless or fraudulent.

A carbon project only generates credits as long as it can prove it is still achieving the emissions reductions it claimed. Monitoring is the ongoing process that provides that proof. If monitoring ceases, the registry has no basis to verify that the project is still working. The credits it already issued may remain valid for a period, but no new credits can be issued. Eventually, the registry will delist the project, and any credits still in circulation become unbacked claims.

What "stops being monitored" actually means

Monitoring is the regular collection of data that shows a project is still reducing or removing emissions as planned. For a forestry project, that might mean satellite imagery, drone flights, or on-the-ground surveys to confirm trees are still standing. For a methane capture project, it means continuous measurement of gas flow and destruction rates.

If a project stops collecting this data, it cannot produce the monitoring reports that registries like Verra or Gold Standard require. Without a current monitoring report, the project cannot undergo the verification audit that confirms its claims. Without verification, the project is effectively inactive.

The immediate consequences

1. No new credits can be issued. The registry will not approve the issuance of any further credits from the project until monitoring resumes and a new verification is completed.

2. Existing credits may still trade. Credits already issued and sitting in registry accounts remain technically valid until their vintage year expires or the registry takes action. But their market value drops sharply because buyers cannot be sure the project is still delivering the environmental benefit the credits represent.

3. The project enters a grace period. Most registries give projects a window - typically one to two years - to resume monitoring and complete a delayed verification. During this period, the project is listed as "on hold" or "suspended."

4. If monitoring does not resume, the project is terminated. The registry permanently delists the project. All remaining unretired credits are cancelled or the registry blocks their transfer. Retired credits stay retired - they cannot be un-retired - but the claim those credits supported becomes unreliable.

What happens to tokenised carbon credits

If a project that was tokenised stops being monitored, every token that claims to represent a credit from that project faces the same problem. The underlying registry credit loses its backing, so the token is no longer backed by a valid credit.

• Tokens representing already-retired credits are the least affected. The retirement happened, so the claim attached to that retirement was valid at the time. But if the project later collapses, the long-term permanence of the emission reduction is in doubt. A forestry project that stops monitoring may be burning or being logged, meaning the carbon it was supposed to store is being released.

• Tokens representing unretired credits become near-worthless. No reputable buyer will pay for a token that traces back to a terminated project. The token may still trade on a secondary market, but it is effectively a speculative token with no link to a real emission reduction.

• The token issuer may be unaware. Many tokenised carbon projects are packaged and sold by intermediaries who do not continuously monitor the registry status of every credit they have tokenised. The token can remain listed on a marketplace long after the underlying project has been suspended. This is one reason why a buyer must check the registry status of the project, not just the token.

How to check if a project is still monitored

You can check the status of any registry project directly. The registry will show whether the project is active, on hold, or terminated, along with the date of its last monitoring report.

• On Verra's registry, look for the "Project Status" field. It will say "Registered," "Under Verification," "Suspended," or "Withdrawn."
• On Gold Standard's registry, the status is shown as "Active," "On Hold," or "Cancelled."
• The last monitoring report date is also listed. If it is more than two years old for most project types, the project is likely in trouble.

What to do with a token from a terminated project

If you hold a token whose project has been terminated, the token has no carbon value. You cannot retire it to make a valid claim. Retiring the token would only destroy the token itself - it would not cancel the underlying registry credit, because that credit has already been cancelled or is no longer valid.

Some marketplaces will voluntarily buy back tokens from terminated projects, but they are under no obligation to do so. The terms of the token sale usually specify that the buyer bears the risk of project failure.

Why this matters more than you might think

A project that stops monitoring does not simply stop producing new credits. It raises questions about every credit it ever issued. If a forestry project abandoned its monitoring because the trees burned, then the emission reductions it claimed for the past decade may have been reversed. The registry does not automatically claw back old credits in that case - the credits remain in circulation until someone retires them.

This is the permanence problem that carbon markets have never fully solved. A project can be monitored for ten years, issue credits for ten years, and then fail. All the claims made using those credits were based on an assumption that did not hold. Tokenisation does not change this. It only makes the credits easier to trade, and easier to buy without realising the project behind them is already dead.
