How do carbon markets work?
Carbon markets are systems designed to facilitate the trading of carbon assets, such as emission allowances or credits, with the goal of reducing global greenhouse gas (GHG) emissions by providing economic incentives for emission reductions.
These markets can be categorized into two main types: compliance and voluntary markets.
Compliance Markets: These are regulated by mandatory emission reduction schemes set by governments or regulatory bodies to achieve specific emission targets. Entities must hold allowances equivalent to their emissions; if they emit less, they can sell surplus allowances, and if they emit more, they must purchase additional ones. Examples include the European Union Emissions Trading System (EU ETS) and California's Cap-and-Trade Program. These markets are characterized by stringent project certification standards to ensure the integrity of the credits traded, as noted in (1)
Voluntary Markets: Here, organizations and individuals purchase carbon credits to offset their emissions voluntarily, often motivated by corporate social responsibility or to enhance their environmental profiles. These markets operate outside regulatory requirements and are driven by the participants' objectives (2)
The function of carbon markets involves several key components:
- Emission Allowances and Credits: Allowances permit the holder to emit a specific amount of GHGs, typically one metric ton of CO₂ equivalent, while credits represent verified reductions or removals of GHGs from the atmosphere, such as through renewable energy projects or reforestation efforts. This was highlighted by the United Nations Environment Programme (UNEP).
- Trading Mechanisms: In compliance markets, trading occurs within a cap-and-trade system, where a cap is set on total emissions and entities trade allowances to meet individual targets. In voluntary markets, the trading is based on purchasing and selling credits to offset emissions (UNEP).
- Verification and Standards: To maintain credibility, projects generating credits must adhere to established methodologies and undergo verification by independent third parties. Standards and registries play a crucial role in tracking the issuance, transfer, and retirement of credits (UNEP).
By assigning a monetary value to GHG emissions, carbon markets encourage businesses and individuals to invest in cleaner technologies and practices, thereby supporting global efforts to mitigate climate change. This concept is supported by sources such as KPMG and UNEP, which provide insights into how these markets operate and their role in climate finance.
