Russia Introduces Carbon Unit Reservation System to Guard Against Reversal Risk

The Russian government has approved a procedure for reserving a portion of carbon units when they are issued from climate projects carrying a risk of future greenhouse gas release, such as carbon capture and storage projects, with the resolution taking effect on 1 March 2027 and remaining in force until 1 March 2033. Under the mechanism, part of the carbon units issued from qualifying projects will be credited to a special reservation account, where they cannot be sold, pledged, encumbered or seized, and can only be released to a withdrawal-from-circulation account once a verified report confirms the project's implementation. Russia's carbon units register currently holds approximately 37.66 million carbon units and more than 535,200 compliance units in circulation.

 

Why Permanence Risk Specifically Matters for Carbon Capture Projects

 

Carbon capture and storage projects carry a distinct risk that many other climate project types do not: the possibility that stored carbon dioxide could later leak or be released back into the atmosphere, undoing the emissions reduction the project's credits were originally issued to represent. Unlike a renewable energy project, where the emissions avoided by generating clean electricity are effectively permanent once that electricity has displaced fossil fuel generation, a carbon storage project's climate benefit depends on the carbon actually remaining sequestered indefinitely, a condition that cannot be fully guaranteed at the moment credits are first issued.

The reservation account mechanism addresses that specific timing mismatch by holding back a portion of newly issued units as a buffer, functioning similarly to an insurance reserve that can absorb the impact if a later verification finds the project's stored carbon has been compromised or released, protecting the overall credibility of the carbon unit system from individual project failures that might otherwise undermine confidence in units already sold and used for offsetting claims.

How the Mechanism Structurally Prevents Premature Trading

 

The specific restrictions placed on reserved units, that they cannot be alienated, pledged or encumbered, and are not subject to seizure, ensure the buffer functions as intended rather than being circumvented through financial transactions. If reserved units could be sold or used as collateral before a project's implementation was independently verified, the reservation mechanism would fail to provide genuine protection, since the units would already be in circulation and potentially used for offsetting claims regardless of whether the underlying project ultimately performed as expected.

Requiring a verified implementation report before units move from the reservation account to the formal withdrawal-from-circulation account creates a structured, auditable checkpoint that ties the release of reserved units directly to confirmed project performance rather than simply the passage of time, giving the mechanism genuine substance rather than functioning as a procedural formality.

Why This Reform Connects to Russia's CORSIA Ambitions

 

The Economic Development Ministry has previously stated it is adjusting Russia's carbon unit issuance system to align with international practices for implementing climate projects, driven partly by Russia's stated intention to participate in CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation. CORSIA is an international mechanism requiring participating airlines to offset a portion of their emissions using approved carbon credits, and gaining recognition for a national carbon credit system under that framework typically requires meeting specific international integrity standards, including credible safeguards against exactly the kind of reversal risk this reservation mechanism is designed to address.

That connection suggests this domestic regulatory reform is at least partly motivated by external validation requirements rather than purely domestic carbon market considerations, positioning Russia's carbon unit system to potentially qualify for international recognition under a scheme that has become an increasingly important reference point for carbon credit quality standards globally.

What the Current Market Scale Reveals

 

With approximately 37.66 million carbon units and more than 535,200 compliance units currently in circulation, and more than 120 million additional carbon units planned for issuance from already registered climate projects, Russia's carbon unit market appears positioned for substantial future growth relative to its current scale, meaning the reservation mechanism approved today will need to govern an issuance volume more than three times the current circulating total as those registered projects come online. Whether this reservation system proves robust enough to maintain confidence in Russia's carbon unit market as issuance scales toward that much larger volume, and whether the reform succeeds in bringing the system into sufficient alignment with international standards to support Russia's stated CORSIA participation goals, will determine how significant this regulatory change proves for both domestic market credibility and Russia's broader international carbon market ambitions.
