Emissions trading in the EU
Emissions trading is one of the EU’s most important tools for achieving the commitment to reducing greenhouse gas emissions. The goal is to create an effective European emissions trading market with the least possible negative impact on economic development and employment within the Union.
The EU ETS was launched in January 2005 and today comprises approximately 10,000 industrial and energy production industries, including around 1500 aircraft operators. EU ETS operates in the 27 member states of the EU, as well as in Norway, Liechtenstein and Iceland (EEA-EFTA states).
Since 2020, the Swiss emissions trading system is linked to EU ETS.
The trade is regulated by an EU directive (2003/87/EC), which covers all EU member states and is in the national law of each country.
Cap-and-trade system
The EU ETS is a so-called Cap-and-trade system and covers about 40 % of the total volume of EU greenhouse gas emissions. The system sets an emission cap for all participants in the system. Then emission allowances are created that allow the release of greenhouse gases where every allowance corresponds to 1 tonne of carbon dioxide equivalents.
The level of the cap determines the number of allowances in the system and is designed to decrease annually from 2013 by 1.74 % per year. The annual decrease between 2021 and 2030 is 2.2 %. The gradual reduction allows companies to slowly adapt to meet increasingly ambitious emission reduction targets.
The total reduction between 2005 and 2020 amounted to 21 %.
Carbon leakage
Carbon leakage is the term used for businesses that are in risk of moving their business to countries with less ambitious emission reduction targets if they would have to pay in full for their emissions in the EU ETS.
Each year, part of the allowances is allocated free of charge to industrial sectors where there is a risk of so-called carbon leakage.
All other emission allowances in the system are sold through auctioning.
After each year, an operator included in the ETS must surrender one allowance per tonne of carbon dioxide equivalents released during the previous year. If the operator does not have sufficient allowances, either proactive measures must be taken to reduce emissions or allowances must be purchased on the market, by auction or from other participants in the system.
