Pooling demand through an ERC buyer’s club could send a strong market signal and improve the expected cash flows of ERC activities, reducing ERC market risk and helping to unlock debt capital. Those benefits can potentially be heightened through an Article 6.2 club that provides a government-sanctioned path to market, thus also reducing political risk. Pooling demand is attractive from an ERC buyer’s perspective because it helps stimulate ERC supply and allows delivery risk to be distributed across buyers.
An ERC club should serve not simply as a buyer’s club, but it can also reduce market frictions and transaction costs for ERC activities and buyers. An ERC club would act as a platform for multiple parties across the value chain of ERC financing to coalesce around specific rules and approaches that standardize all ERC transactions that occur through the club. That can create a high-integrity environment for trade while the broader market continues to mature. This could be attractive for buyers broadly to bolster the integrity of their claims of buying and using high-quality ERCs and could be particularly attractive for mid-sized buyers that might face reputational and regulatory scrutiny but find it difficult to engage in extensive due diligence of ERC purchases on its own.
There are multiple potential iterations of an ERC club (Figure 15), including a:
- Voluntary Club pooling demand from a group of voluntary ERC buyers who combine capital to finance ERC activities directly.
- Sovereign Article 6.2 Club comprised of buyer and seller countries that are party to the Paris Agreement's Article 6.2, under which countries can cooperate to achieve their emissions reduction targets by trading international mitigation outcomes (ITMOs). A sovereign Article 6.2 club could agree upon a set of rules and procedures for creating and transferring mitigation outcomes. Seller countries must have a corresponding adjustment but buying countries do not have to “use” that corresponding adjustment and there could be a mechanism to repatriate the mitigation outcome, allowing a contribution to the selling country’s NDC.
- Article 6.2 Club w/ Private Parties comprised of buyer and seller countries, in addition to private parties invited by their host governments to purchase ITMOs for other international mitigation purposes. This would have the same benefits as a sovereign 6.2 club and potentially expand the pool of buyers seeking ERCs with a corresponding adjustment (though buying countries and private parties would not have to use that corresponding adjustment).
The ERC club could be designed as a standalone entity or, alternatively, could build upon or be housed in existing efforts that seek to achieve similar or complimentary goals.1

A DFI could help convene and organize the policies and procedures of and trade among an ERC club. For any version of an ERC club, it is critical the club has a clear and transparent governance structure that ensures consistency across the ERCs being traded and, in the case of an Article 6.2 club, minimizes the risk of double counting and leakage. This offers one potential role of DFIs, particularly multilateral institutions, which are well placed to organize and manage an ERC club thanks to their credibility and convening power.
