Compliance carbon markets are government-regulated systems where major polluters must hold permits, known as allowances, for their greenhouse gas emissions. By putting a legally binding price on carbon, these markets create a powerful financial incentive for industries to decarbonize and invest in cleaner technologies.
Compliance carbon markets, also known as regulated or mandatory markets, are foundational policy tools established by governments to control and reduce greenhouse gas (GHG) emissions on a large scale. Their primary goal is to enforce legally binding emissions reduction targets in line with national or international climate commitments, such as the Paris Agreement. These systems primarily target high-emitting sectors like power generation, heavy industry, and aviation, obligating them to account for every tonne of CO0 they release into the atmosphere.
Most compliance markets operate on a "cap-and-trade" principle, which works through a few key steps:
- The 'Cap': A government or regulatory body sets a firm, gradually decreasing limit, or "cap," on the total amount of greenhouse gases that can be emitted by all regulated entities over a specific period.
- Allowances: This total cap is divided into tradable permits or "allowances." One allowance typically represents the right to emit one tonne of CO0 equivalent (tCO0e). These allowances are either allocated to companies or, more commonly, auctioned by the government.
- Trading: The "trade" component creates a flexible market mechanism. Companies that can reduce their emissions at a low cost can sell their surplus allowances to companies for whom reducing emissions is more expensive or technologically challenging. This ensures that emissions are reduced in the most cost-effective way across the economy.
- Compliance: At the end of each compliance period (usually a year), every regulated company must surrender enough allowances to cover its total verified emissions. Companies that fail to do so face heavy financial penalties, making compliance a critical operational and financial requirement.
This "polluter pays" principle creates a direct financial cost for emitting carbon, which in turn drives innovation and investment in low-carbon solutions and technologies.
Concrete Examples
- The European Union Emissions Trading System (EU ETS): As the world's first and largest compliance carbon market, the EU ETS is the cornerstone of the EU's climate policy. It regulates thousands of industrial facilities and airlines, covering approximately 40% of the bloc's total GHG emissions and influencing global climate finance.
- The UK Emissions Trading Scheme (UK ETS): Following its departure from the EU, the United Kingdom established its own standalone market. The UK ETS functions similarly to its European counterpart, setting an independent national cap on emissions for energy-intensive industries, the power sector, and aviation routes within the UK.
The allowances from these markets, such as European Union Allowances (EUAs) and United Kingdom Allowances (UKAs), are traded financial instruments. Their value fluctuates based on supply (the cap set by regulators) and demand (driven by economic activity, fuel prices, and climate policy ambition), making them a unique asset class.
