Carbon market: What is the Community Emissions Trading System?
Summary
The European Union Emission Trading System (EU ETS) is a European mechanism aimed at reducing greenhouse gas emissions by limiting the number of emission allowances available to companies. It operates on the "cap-and-trade" principle, where companies can buy and sell emission allowances while adhering to a fixed cap that progressively reduces emissions.

Definition of EU ETS and the carbon market
The carbon market is a system for trading greenhouse gas (GHG) emission rights. The EU ETS (European Union Emission Trading System) is a mechanism established by the European Union to regulate GHG emissions. It works on the “cap-and-trade” principle, which sets a cap on total emissions allowed for the most polluting sectors, such as heavy industry and electricity production.
Companies receive or purchase allowances representing a specific number of CO2 tons they are allowed to emit. If they emit less than allocated, they can sell their excess allowances on the market. If they exceed their quota, they must buy more or face financial penalties.
The EU ETS plays a central role in European climate policy. It encourages companies to gradually reduce their carbon footprint and invest in cleaner technologies. By reducing the number of allowances available each year, the EU aims to cut CO2 emissions continent-wide. This system contributes to achieving the climate goals of the Paris Agreement and the European Green Deal.
How does the carbon market and EU ETS work?
The EU ETS operates by setting a cap on the total emissions allowed each year for certain economic sectors. This cap is reduced annually to meet the EU’s climate goals. Companies in these sectors receive emission allowances, which represent the right to emit one ton of CO2.
Companies can trade these allowances on the carbon market. If they emit less than their allowance, they can sell the remaining rights to other companies. Conversely, if they exceed their allowance, they must buy additional allowances to avoid penalties. This system creates a financial incentive to reduce emissions, as companies benefit from saving or selling excess allowances.
A carbon credit is an allowance representing one ton of CO2 or its equivalent in other greenhouse gases. The idea is to encourage innovation and energy efficiency while maintaining strict control over global emissions. The system’s annual reduction in the number of available allowances forces companies to lower their emissions in line with the EU’s GHG reduction targets.

Objectives of the EU ETS
The EU ETS has several key objectives:
- Reduce CO2 emissions in the European Union: The EU ETS aims to progressively reduce GHG emissions by setting an annual cap on emissions for the most polluting sectors. This cap is lowered each year to accelerate the transition to a decarbonized economy.
- Contribute to the climate goals of the Paris Agreement: The EU ETS is one of the main tools for the EU to meet its commitments under the Paris Agreement, which aims to limit global warming to less than 2°C above pre-industrial levels, and ideally to 1.5°C.
- Encourage investment in low-carbon technologies: By putting a price on carbon emissions, the EU ETS encourages companies to invest in environmentally friendly solutions and technologies, such as renewable energy, energy efficiency, or carbon capture and storage.
Tip
To reduce your emissions under the EU ETS, consider investing in low-carbon technologies and improving the energy efficiency of your infrastructure, while keeping a close eye on the allowances available on the carbon market.
Sectors covered by the EU ETS
The EU ETS applies to several economic sectors responsible for significant GHG emissions in Europe:
- Heavy industries: Sectors like steel, cement, and chemical production are major emitters and are subject to the EU ETS. These industries are energy-intensive and produce substantial CO2 emissions. The EU ETS aims to reduce their carbon footprint by encouraging cleaner technologies.
- Electricity and heat production from fossil fuels: Power plants running on coal, gas, or oil are also regulated under the EU ETS. Their CO2 emissions are capped, so they must either reduce their fossil fuel consumption or purchase carbon credits to offset their emissions.
- Newly included sectors like aviation: In recent years, aviation has been included in the EU ETS. Airlines operating in Europe must purchase emission allowances to cover a portion of their emissions, encouraging them to improve energy efficiency or invest in less polluting solutions.
Carbon market: the benefits of the EU ETS
The EU ETS offers several benefits for both businesses and the environment. Firstly, it provides companies with flexibility. They are encouraged to innovate to reduce emissions while complying with their allocated quotas. Companies that successfully cut emissions below their quotas can sell excess allowances, generating additional revenue. This flexibility promotes the adoption of cleaner technologies and encourages businesses to be more energy-efficient.
The EU ETS also contributes to the development of a genuine carbon market in Europe. This market creates strong economic incentives to invest in low-carbon solutions, fostering the emergence of new green technologies such as carbon capture and storage (CCS) or renewable energy.
Since its implementation, the EU ETS has significantly reduced GHG emissions in Europe. By imposing strict limits on the most polluting sectors, the system has contributed to lowering emissions in key sectors such as heavy industry and electricity production. It plays a vital role in meeting European climate objectives.
Challenges of the EU ETS
The EU ETS also faces several challenges that may limit its effectiveness. One of the main risks is carbon leakage. This occurs when heavily polluting industries relocate their operations to countries with less stringent or nonexistent environmental regulations. As a result, emissions are not actually reduced, but simply shifted elsewhere.
The administrative complexity of the EU ETS is another challenge. For companies, complying with the system’s requirements can entail significant costs related to management, compliance, and monitoring emission quotas. This can create additional constraints, especially for small and medium-sized enterprises (SMEs), which have fewer resources to adapt.
Lastly, carbon price volatility and the adjustment of quotas present a challenge for the carbon market. Fluctuations in carbon prices can make long-term planning difficult for businesses. If emission quotas are not properly adjusted, excessive price volatility could undermine market stability.
EU ETS vs. other carbon pricing systems
The EU ETS operates on the “cap-and-trade” principle, where a cap is set on emissions, and companies receive or purchase quotas that can be traded. A carbon tax, by contrast, imposes a fixed cost per ton of CO2 emitted, without a predefined emissions limit. The EU ETS offers more flexibility, incentivizing companies to reduce emissions or trade allowances. A carbon tax is simpler to administer but does not guarantee direct emissions reductions.
Other systems similar to the EU ETS exist globally. For example, Canada’s carbon market uses a hybrid model combining an emissions cap and a carbon tax. South Korea’s cap-and-trade system covers sectors including industry, electricity production, and aviation. California, in the U.S., also has a carbon market integrated with Quebec’s, considered one of the most advanced in North America. These systems reflect regional approaches to combating climate change.
The future of the EU ETS and the carbon market
The future of the EU ETS lies in its expansion to new sectors. The EU plans to include road and maritime transport, as well as the building sector. These additions will cover sectors that still emit significant amounts of CO2, further enhancing the carbon market’s effectiveness.
The European Green Deal, which aims to make Europe climate-neutral by 2050, plays a central role in the future of the EU ETS. It proposes lowering emission caps and gradually reducing the number of allowances available on the market. This approach will increase pressure on companies to invest in low-carbon technologies and encourage green innovation.
Finally, the EU ETS seeks to integrate more with global climate policies. Cooperation with other carbon markets, such as those in California, Canada, or South Korea, is envisioned to create a more harmonized and effective global carbon market. This integration could promote universal carbon pricing, encourage emissions reductions on a global scale, and help meet the goals of the Paris Agreement.
