The EU Emissions Trading Scheme (ETS) was established in 2005. All countries that make up the European Union made the decision to impose emissions restrictions on their companies that emit large amounts of greenhouse gases each year.
The overarching goal of the EU ETS is to reduce greenhouse gas emissions from energy-intensive industries by a certain percentage each year. As of 2013, the goal was set at 1.74 percent to achieve a reduction of 21 percent by 2020.
With the EU ETS, the European Union has given CO2 emissions a price, and set incentives to reduce emissions in cost-effective ways. The EU ETS scheme has considerably reduced emissions in power generation and energy-intensive industries, by 42.8 percent in the past 16 years.
Similar to the UK EST, to comply with the EU ETS, participating companies must properly allot their given number of allowances corresponding to their CO2 emissions each year. This makes burning coal and other fossil fuels for energy more expensive, and clean power sources more cost-effective and appealing. Therefore companies become incentivised to improve their energy-efficiency, as they can opt to sell their emissions permits on the market for a financial gain, rather than use up their allowances for the carbon they produce and potential penalties if going over set limits (see below).
The EU ETS is guided by a “cap-and-trade” approach: the EU sets a cap on the amount of greenhouse gases that may be emitted each year, and companies need to hold European Emission Allowance (EUA) for every tonne of CO2 they emit within a given year. They can gain, buy, or trade these permits.
The mandates imposed by the EU ETS apply to organisations that emit CO2 from power stations, as well as energy-intensive industries (for example: oil refineries, steelworks, and producers of iron, aluminium, cement, paper, and glass) and commercial aviation. Extra-EU flights are not included in the EU ETS scope; only flights between and within countries in the EU and European Economic Area must comply.
Non-complying companies face a financial penalty if they emit more CO2 than they have been granted in allowances, these penalties are typically 100 euros per excess tonne.
Also, instead of receiving free allowances directly from the EU ETS, companies can buy credits from emission (known as carbon offsetting) and invest in projects under the Kyoto Protocol’s Clean Development Mechanism (CDM) in developing countries. This is popular with heavy energy users that cannot avoid high emissions.
