A compliance carbon market is a regulated market in which emitters covered by a mandatory cap must surrender allowances or credits equal to their emissions, created under law to enforce climate targets. Prices are set by the supply of capped allowances and demand from regulated entities, creating a financial incentive to abate. It stands in contrast to voluntary carbon markets, where participation and credit purchase are discretionary.
Overview
- Compliance markets arise when governments impose a binding limit on emissions and require covered entities to hold permits for what they emit. The cap creates scarcity, and trading lets reductions occur where they are cheapest.
- Because participation is mandatory and enforced by penalties, compliance markets generate durable price signals and substantial trading volumes, unlike voluntary markets driven by reputational or contractual demand.
- Major schemes have been established under international agreements and national or regional legislation, with rigorous measurement, reporting and verification to maintain integrity.
Key aspects
- Mandatory cap: a legal limit on aggregate emissions for covered sectors.
- Allowance surrender: emitters must hold and retire permits matching emissions.
- Tradability: allowances and eligible credits can be bought and sold.
- Price discovery: market clearing sets a carbon price that drives abatement.
- Enforcement: non-compliance incurs financial and legal penalties.
Mechanisms
- Cap-and-trade allocation, auctioning and surrender cycles.
- Registry accounting to prevent double counting of allowances and credits.
- Measurement, reporting and verification of covered emissions.
- Linkage between jurisdictions to broaden the market.
Applications
- Power, industry and aviation emissions regulation.
- Implementing national climate commitments under international treaties.
- Generating revenue for climate finance through allowance auctions.
