The EU Emissions Trading System (EU ETS) is the world's largest 'cap-and-trade' program, setting a mandatory limit on greenhouse gas emissions for key industrial sectors. It works by creating a market for carbon allowances (EUAs), turning carbon emissions into a tradable asset to drive decarbonization cost-effectively.
The EU Emissions Trading System (EU ETS) is the cornerstone of the European Union's policy to combat climate change. It operates on a "cap-and-trade" principle, which makes it a market-based tool designed to reduce emissions in a predictable and economically efficient way. The system covers over 10,000 heavy-energy-using power stations and industrial plants, as well as aviation operators, which are collectively responsible for about 40% of the EU's total greenhouse gas emissions. Its primary goal is to help the EU achieve its ambitious climate targets, including climate neutrality by 2050.
How It Works
The mechanism works through a few key steps:
- The “Cap”: The EU sets a firm, economy-wide cap on the total amount of certain greenhouse gases that can be emitted by the facilities covered by the system. This cap is reduced over time, ensuring that total emissions fall.
- The “Allowances”: Within the cap, companies receive or buy emission allowances, known in the market as European Union Allowances (EUAs). One allowance gives the holder the right to emit one tonne of carbon dioxide (CO₂).
- The “Trade”: Companies that can cut their emissions at a low cost can sell their excess allowances to other firms for which reducing emissions is more expensive. This trade creates a market price for carbon, fostering innovation and investment in clean technologies.
- Compliance: At the end of each year, each company must surrender enough allowances to cover its total verified emissions. If a company fails to do so, it faces heavy fines.
This system not only guarantees emission reductions but also creates a new asset class—carbon allowances—which can now be accessed by investors.
Concrete Use Cases
- For an Industrial Company: A steel manufacturer invests in a more energy-efficient furnace. This reduces its annual emissions, leaving it with surplus EUAs. The company can then sell these allowances on the market, generating revenue that helps offset the cost of the new technology.
- For an Investor: An individual investor believes that as the emissions cap tightens, the price of EUAs will increase. Using a platform like Homaio, they can learn more about European Union Allowances (EUAs), diversify their portfolio, and potentially generate returns, while reinforcing the carbon price signal that encourages industries to decarbonize.
