PUBLIC SPONSORSHIP OF CARBON MARKET OPERATORS

Governments can establish, supply capital to or jointly own a carbon-market operator, or give an existing operator a defined public-service mandate. The operator then maintains the staff, buyer services and trading venue needed to connect eligible suppliers and purchasers. Public backing can sustain these services while transaction fees are insufficient to cover their costs. For CDR, the mandate should specify which removal services the operator must provide and how it will distinguish removals from other carbon credits. This lever concerns the decision to sponsor an operating institution. Market Infrastructure for Removal Units covers the underlying contracts, registries, price information and settlement systems that complete payment and unit transfer, which a publicly sponsored operator may use or commission.

Authorities should choose between a public company, a jointly owned company and a competitively awarded operating mandate according to the missing service and the institutions already available. The founding documents need to distinguish a commercial return objective from duties such as open access, buyer education or publication of market data. Capital contributions, operating grants and any exclusive right should each have a stated purpose and review date. The responsible ministry or public investor should exercise ownership separately from the regulator that supervises trading and the bodies that certify removal quality. A CDR remit also needs clear treatment of durability, delivery dates and replacement obligations, so a general carbon exchange does not present unlike credits as equivalent products. Public ownership should not give affiliated buyers or suppliers privileged access to listings, prices or customer information.

A sponsor can pay for useful services that individual traders will not finance while demand is still developing. A permanent operator can retain specialist staff, help new purchasers understand products and maintain predictable access to trading. Public-service conditions can require publication of fees, impartial admission of suppliers and continued access for smaller participants. Where an existing exchange has suitable systems, a sponsored CDR service can build on those capabilities without creating another venue. These benefits depend on a clear service gap and actual use. State involvement can improve continuity and accountability, but the credibility of the units still depends on their certification and the transactions that follow.

A government may subsidise a venue that buyers do not need, dividing activity among several operators and repeatedly supplying new capital to a loss-making company. An exclusive mandate can become a protected monopoly, while a public shareholder can favour domestic suppliers or pressure the operator to show impressive trading volumes. The public brand may be mistaken for a guarantee that every credit is environmentally sound or that the state will meet a supplier's delivery obligations. If the operator earns fees from listings and transactions, commercial incentives may conflict with strict admission and disclosure requirements. Political appointments, opaque trades with its owners and affiliated companies and mixing ownership with supervision can weaken confidence in both the venue and its public sponsor.

The sponsor should assess whether its contribution buys services that would otherwise be missing. Reporting can connect gross capital and operating support with active independent buyers, supplier coverage, repeat transactions, fees, settlement failures and use of buyer assistance. CDR activity should be reported separately from other carbon credits, and completed transactions separately from verified removals delivered and retired. Ownership reviews should examine conflicts, preferential treatment, complaints and dependence on a few affiliated customers. Persistent low use, rising subsidies or exclusion of credible suppliers should trigger changes to the mandate, competitive retendering, consolidation or an orderly exit that protects transaction records and customer assets.

The public shareholder or commissioning authority should define the service obligation and decide how much capital or operating support it will provide. Financial and environmental regulators should clarify their respective supervision and certification responsibilities. Existing exchanges and service providers can test whether the proposed institution fills a gap and what it would cost to operate. Removal suppliers, buyers and smaller intermediaries should help define admission, fees and product information. Independent technical experts and civil society can examine the quality claims attached to public sponsorship, while auditors scrutinise related-party transactions and the use of public resources.

Supranational authorities and national, regional or municipal governments can sponsor an operator where their investment or public-enterprise powers authorise ownership or commissioning. The necessary mandate should be checked separately from national financial supervision. Exchange companies have a joint implementation role when they co-invest, establish and govern the sponsored service. Taiwan's joint founding and statutory entrustment of its carbon exchange illustrate the distinction between sponsorship, operation and regulatory authority.
