How Does Carbon Cap and Trade Work? A Comprehensive Guide
A carbon cap-and-trade system such as the EU ETS puts a price on carbon emissions through the dynamics of free financial markets.
You will find a monthly newsletter for exclusive updates on carbon markets, some white papers on diferent subjects and our exclusive prices reports.
Starting in 2024, the EU ETS will extend its coverage to include the maritime shipping sector. Discover the potential impact of carbon pricing on the industry and learn about the forthcoming steps for maritime shippers.
The European Union Emissions Trading Scheme (EU ETS) is the main policy tool in achieving Europe’s climate targets. It is engineered in such a way that the more participants in the market and the more industries covered, the more effective the system gets to fight global warming. In this context, the European Commission is expanding the scope of the scheme in 2024: there is an EU ETS shipping inclusion. This means that shipping companies will now keep track of the volumes of CO2 that they produce, and then buy and surrender an equivalent amount of European Union Allowances (EUAs) to match them, under the new EU ETS for maritime. We’ve already covered some of this in our article published in Social Europe.
As a refresher, the European Union Emissions Trading System (EU ETS) is a cap-and-trade system implemented by the European Union to reduce greenhouse gas emissions. Under this system, a cap is set on the total amount of CO2 that can be emitted by covered entities (industries that produce electricity, steel, cement, etc). The European Commission issues EUAs, each corresponding to 1 tonne of CO2. Industrial companies and manufacturers are obliged to buy an amount of EUAs from the European Commission, in a number equivalent to the volumes of CO2 that they emit every year. The overall quantity of emissions (and EUAs respectively) is decreasing over time as the cap is gradually reduced. As EUA supply decreases, its unit price increases. Therefore, market participants are incentivized to invest in cleaner technologies and reduce their carbon footprint.
As seen in our EU ETS guide, the EU ETS sectors covered before 2024 were:
The maritime shipping sector represents 2.8% of global CO2 emissions. It accounts for 3 to 4% of the EU total CO2 emissions. In 2022, the European footprint of the sector expanded by 5% compared to 2021, reaching a 3 year peak. This growth was driven by a rapid increase in the use of carbon-intensive fuels. Despite a significant technological potential for emission reduction, progress has been unsatisfactory due to a lack of market incentives.
The new EU ETS directive will apply to cargo and passenger ships of or above 5000 gross tonnage (GT) from 2024 on. Then it will shift to also cover offshore ships of or above 5000 GT starting in 2027. The European Commission describes the extension as “flag-neutral and route-based”. This means that it covers:
In 2018, emissions in the shipping sector amounted to 1 076 million tonnes of CO2, and the International Maritime Organization estimates that those can go up by 130% by 2050 - this can be a serious threat to the carbon net-zero European commitments. To limit the carbon intensity of the maritime shipping industry and in order to align with the Fit for 55 commitment (reduce emissions from the sectors covered by the EU ETS by 62% by 2030 compared to 2005-levels), shipping companies will have to buy EUAs to account for
As we’ve seen here, we can expect a rise in annual costs for shippers up to €10 billion once the scheme covers all emissions from the sector. Estimates from industry representatives like Maersk, Hapag-Lloyd and CMA CGM foresee an increase of€7 to €105 per TEU after the introduction of the EU ETS expansion (a TEU is a unit of cargo capacity based on the volume of a 20-foot-long (6.1 m) intermodal container).
Taking into account the large volumes of goods transported by every vessel, the financial impact on the price of every unit shipped will be insignificant. To give you a quantitative idea, an average ship has a volume of 8,000 TEU with each container holding around 20 tonnes. It burns around 225 tonnes of marine gas oil per day at a price of €900 per tonne. Each tonne of fuel consumed emits 3.11 tonnes of CO2. So, for a Rotterdam-Athens trip of 13 days, the fuel cost for transporting one tonne of merchandise would be €16.45. If we add €80 per emission allowance (an indicative level from the past 3 years), the transport expense increases by 26.6% to €20.83. And, taking the average weight of a shoe-box, this would only represent an increase of €0.02 per shoebox.
Multiple industry representatives have advanced several criticisms, notably related to logistics. There are objections on the old-looking, non-intuitive softwares and platforms used to open an account in the registry. Others mention the lack of clarity for larger companies when it comes to matching the emissions of their different vessels to different account numbers ( and then matching them to EUAs surrendered). Finally, the fact that only a very selective group of the company’s representatives can access the Union Registry (for security reasons), is also seen as a burden by some maritime operators.
As a response to the above concerns, a lot of NGOs, consultants and representatives of the EU institutions have come forward to defend the implementation of the EU ETS expansion to the maritime shipping sector. For instance, Gorrissen Federspiel explains what is behind all the complex words seen when following the EU ETS compliance guidelines. The French government, through its Direction des Pêches Maritimes et de lAquaculture has organized several webinars to contribute to the smooth transition to broadening the EU ETS scope.
