The traditional market for CO₂ certificates faces several structural challenges that limit its efficiency and accessibility:
- High entry barriers: Access to the CO₂ market has traditionally been reserved for large companies and institutional investors, as certificates are typically traded only in large volumes (whole tonnes of CO₂) and at high total amounts.
- Lack of transparency: The origin, quality and life cycle of CO₂ certificates are often difficult to trace, which undermines trust and willingness to invest.
- Inefficient processes: Trading traditional CO₂ certificates involves considerable administrative effort, high transaction costs and lengthy settlement times.
- Limited market liquidity: The fragmented market and high entry barriers result in limited liquidity, making efficient trading and price discovery difficult.
- Risk of double counting: Without robust central registries, there is a risk that CO₂ certificates will be counted or sold more than once.
