This innovative system operates on the “cap and trade” principle. Under this mechanism, authorities set a strict ceiling on the total amount of greenhouse gases that plants and aircraft operators can emit. To ensure that emissions fall over time, the EU reduces this cap every year in line with its climate targets.
Participants in the EU ETS must purchase sufficient allowances to cover their environmental impact. While businesses can buy these allowances directly on the EU carbon market, they also receive a specific allocation for free. Consequently, if an operator successfully reduces its emissions, it can keep the remaining allowances for future use or sell them for profit.
Market Dynamics and Revenue Distribution
This financial revenue mainly flows into national budgets. Member States then use these funds to support vital investments in renewable energy, energy efficiency, and low-carbon technologies. In addition, the sale of allowances feeds two dedicated funds for low-carbon innovation and energy transition: the Innovation Fund and the Modernization Fund.
The 2023 Review: Strategic Updates
The landmark 2023 review significantly increased the system’s ambition to achieve global climate goals. Key changes include:
In conclusion, the EU ETS remains a cornerstone system for climate change mitigation. Thanks to the latest 2023 review, the framework now provides a much stronger and more ambitious path toward a low-carbon future.
