The EU ETS is an emissions cap-and-trade system that aims to reduce greenhouse gas (GHG) emissions by setting a limit, or cap, on GHG emissions for certain sectors of the economy.
Each year, a limited number of EU Allowances (EUAs) is made available for trading in the market, and this is reduced yearly in order for the EU to meet its target of a 55% reduction in GHG emissions by 2030 relative to 1990, and net zero by 2050.
Each EUA gives companies a right to emit GHG emissions equivalent to the global warming potential of one tonne of CO2 equivalent.
