The European Union Emission Trading Scheme (EU ETS) was put in place following the Kyoto Protocol - it is a European policytool aiming to reduce carbon emissions. Under the scheme, each tonne of CO2 must be matched to a European Union Allowance (EUA). As the price of EU ETS rises, companies are incentivized to reduce their carbon footprint by investing in decarbonization efforts. The aim is to make sustainable investments economically more appealing than bearing the costs of carbon allowances.

As seen in our guide on carbon cap and trade systems, there is a primary and a secondary market within the EU ETS framework. The primary market is when the European commission issues EUAs through auctions (or gives them away for free). The revenues from these auctions is then centralized and redistributed according to specific mechanisms. They amounted to €152 billion between 2005 and 2022.

How are revenues from the EU ETS generated? 

The EU ETS, a cap and trade system

An emissions trading system (ETS) is a market-based mechanism for reducing greenhouse gas emissions - the objective is to ascribe a cost to each tonne of CO2 emitted. It works by setting a cap on the total amount of emissions that can be released by a group of industrials, such as power plants or factories. Those can receive for free, bid for, or trade emission allowances. At the end of the year, polluters have the obligation to surrender a number of allowances equivalent to their emissions. 

How does the EU ETS auction work?

The European Energy Exchange (EEX) is the standard auctioning platform for all member states participating in the EU ETS, except for Germany and Poland (they have opted for separate national auctions). Auctions are conducted daily from 9 am to 11 am CET, and the outcomes are made public on the EEX's website. The proceeds from the issuing of EUAs are centralized and then redistributed to individual countries. A proportion is kept for the Innovation and modernization funds (read more below). 

The auction process is a “single-round, sealed bid, uniform price auction”. Each bidder indicates the quantity of allowances they wish to purchase and the corresponding price they are willing to pay. The bidding period lasts for a minimum of two hours. Then, the auction platform calculates and discloses the auction clearing price, the point at which the demand for allowances matches the quantity offered for sale on that particular day. Successful bidders are those who placed bids at or above this clearing price. Regardless of their initial bid amounts, all successful bidders pay the same price.

What are the EU ETS volumes?

Between 2005 and 2022 €152 billion were generated from the auctioning of EUAs. Currently, 90 % of the auctioning revenues are redistributed to member states. The remaining 10% of the proceeds go to the innovation fund and the modernisation fund.

The EU ETS: an asset with environmental impact 

Climate change deteriorates human health, infrastructures, it causes mass migration, famines… A lot of financial resources are required to address and repair those damages. The World bank has stated that an annual investment of $5 trillion is needed by 2030 as a response to global warming. In this context, carbon markets are one of the ways to raise the necessary funds to keep tackling climate change - the EU ETS, while directing a massive amount of capital towards climate projects, participates in bridging this finance gap to address global warming.

How do member states use revenues from the EU ETS? 

The rules on EU ETS revenues use

The European Law makes it mandatory for Member states to spend at least 50% of EU ETS proceeds to finance climate projects. Yet, most countries are using almost all of their proceeds for such projects, as seen in the graph below.

The EU energy agency reported that in 2022 an average of 76% of revenues was spent by member states for climate and energy purposes.

How do Member States use their EU ETS auction revenues? An EU case study report

Many climate related projects are seeing the day thanks to financing from the EU ETS auctions. The NGO Emission Trading Extra, committed to advocating for emission trading schemes, has conducted a series of interviews to highlight initiatives funded through the EU ETS.

The EU ETS revenues in France

Until 2018, France has spent all of its auctioning revenues for climate action. It uses all of the EU ETS auction proceeds for a program called “ma prime renov” - a subsidy designed to assist in funding energy renovation projects. The grant amount is determined based on both income and the nature of the renovations. 

After 2018, the amount invested in this program was capped by the government, and the remainder of the revenues from the EU ETS auctions for France go into the general public budget.

The EU ETS revenues in Italy

Italy used 50% of the revenue from the EU ETS to finance climate projects, the remaining of the proceeds going to the general budget. Here are some examples of projects financed by the ETS proceeds:

  • PREPAC  Programme for Retrofitting Buildings of the Central Administration:  it aims to render energy efficient at least 3% of the total central administration building surface.
  • Sustainable Mobility and Buono Mobilita’ Verde: an improvement of public transport lines, such as new subway lines, fortification of railway lines and road links.

The EU ETS revenues in Germany

Germany is the country receiving most proceeds from EU ETS auctions (between 2013 and 2020, it has received €13.1 billion). It uses them all for climate action across several projects. In 2020, the distribution of revenues was as follows:

  • 36.0% CO2 Building Retrofitting Programme (for energy-efficient buildings)
  • 12.9% Grants for electric vehicles (to promote clean transportation)
  • 12.1% Programme for renewable heating
  • 10.8% Compensation for electricity-intensive companies (to offset emissions trading-related cost increases)
  • 6.3% Measures for electromobility

The Innovation Fund and the EU ETS, financing climate initiatives

What is the Innovation Fund?

The Innovation Fund is a programme to help the transition to lower-carbon technologies. Some of the EU ETS auction revenues that are not directly redistributed to Member states go to this initiative. The projects span across various sectors, including energy-intensive industries, renewables, energy storage, net-zero mobility, buildings, hydrogen, and carbon capture, use, and storage.

What projects are financed by the Innovation Fund?

Some examples of projects financed by the Innovation Fund are: 

  • The CarBatteryReFactory: a small-scale manufacturing plant in Germany that produces industrial energy storage systems using second-life car batteries.
  • The ANRAV-CCUS project: a large-scale carbon capture and storage project in Bulgaria.
  • The BioOstrand project: a large-scale commercial deployment of solid biomass-and-power-to- Sustainable Aviation Fuels (SAF) technology in Sweden.

The Modernisation Fund and the EU ETS, financing infrastructures in low incomes member states 

What is the Modernization Fund?

The Modernisation Fund supports the modernisation of energy systems and the improvement of energy efficiency in 13 lower-income EU Member States. It was established in 2018 and aims to help the beneficiary Member States achieve their climate targets and the objectives of the European Green Deal. Just like the Innovation Fund, the Modernisation Fund is financed by revenues from the auctioning of emission allowances under the EU Emissions Trading System (EU ETS).

What projects are financed by the Modernisation Fund?

The beneficiary Member States are Bulgaria, Czechia, Estonia, Greece, Croatia, Latvia, Lithuania, Hungary, Poland, Portugal, Romania, Slovenia and Slovakia.  

Some examples of projects financed by the innovation fund are: 

  • In the Czech Republic, a waste-to-energy plant is being modernized to reduce reliance on natural gas and improve energy efficiency.
  • In Romania, a new solar park is being built to generate electricity from waste and promote renewable energy sources.
  • In Bulgaria, investments are being made to modernize the electricity distribution grid, facilitate electric vehicles, store energy, and decarbonize the energy system.

The Social Climate Fund and the EU ETS, supporting the most vulnerable

From 2027 on, a new Emissions Trading Scheme will be out in place - the EU ETS II. It will cover emissions from building construction and road transportation. Some concerns have merged as to whether this new ETS will negatively impact lower income households unfairly. As a response, the EU has introduced the Social Climate Fund that will operate between 2026 and 2032. It will provide temporary direct income support to the ones affected. Also, the programme will provide funds for improving the energy efficiency of buildings and help uptake low-emission mobility.

Buy EUAs to directly contribute to climate initiatives through the EU ETS

Carbon markets are now accessible to any investor through Homaio’s EU ETS trading platform. By participating in the emission allowances market, you can contribute to the overall reduction of greenhouse gas emissions in the European Union. As seen above, the funds generated through the auctioning of EU Allowances (EUA) play a crucial role in supporting various climate projects and initiatives.
