CDR RESERVE

A CDR reserve is a public stockpile of carbon removal credits set aside for future use. In practice, a government or authority procures and holds verified CO₂ removal certificates in a reserve account instead of retiring them immediately. This creates a strategic buffer that can be drawn later to meet climate targets or to stabilise carbon markets. The concept is analogous to a strategic petroleum reserve, but for stored carbon removals.

Building such a reserve requires upfront investment and rigorous credit quality control. Authorities must decide what types of removals qualify. There should be clear rules for when and how reserved credits can be used – for example, to be released into an ETS at a later date. Legal provisions must allow banking these credits across compliance periods. Transparency is crucial: the reserve’s size, the types of credits, and their intended use should be publicly reported.

A CDR reserve can accelerate the CDR industry by acting as an early, guaranteed buyer for removals. Government procurement to fill the reserve spurs investment in projects, helping scale technologies and drive down costs. It also provides a safety net for climate targets . Moreover, a reserve can smooth carbon market volatility: authorities might buy and bank credits when prices are low and later use them to ease tight markets or compliance costs.

Substantial public funds may be tied up in credits that only yield climate benefits years later. If credit quality is poor, the reserve could fail to deliver its promised offsets, giving a false sense of security. There are also risks of moral hazard: policymakers might lean on the reserve as a crutch and delay necessary emissions cuts. Proper governance is needed to ensure reserved credits remain valid over time and to prevent double-counting or misuse.

Key metrics include the total CO₂ tonnage in the reserve, the types and vintage of credits held, and their permanence status. Annual reports should track additions to the reserve versus goals and disclose the average procurement cost per tonne. Independent auditing of the credits is recommended to verify they maintain integrity over time.

The main actors are government agencies administering the reserve and CDR providers selling into it. Early engagement ensures fair design. Legislators, finance authorities, and carbon market experts help secure funding and rules. NGOs and the public must be reassured it complements, not replaces, emissions cuts.

A city could purchase and hold removal credits, but no direct precedent has been identified, and ownership would need to be reconciled with national inventories and claims rules to prevent double counting.
