Luxembourg is making a significant change to its approach to carbon emissions. Since 2021, the country has had a CO2 tax, collecting revenue to support energy transition projects. Initially set at €20 per tonne, the tax has gradually increased to €45. However, recently, Environment Minister Serge Wilmes announced that Luxembourg will phase out this tax by 2028. Instead, it will join the European-wide Emissions Trading System (ETS2).
What Is ETS2?
The new ETS2 system allows companies to trade carbon emissions allowances. Each allowance permits the emission of one tonne of CO2. This system aims to lower total emissions by reducing the cap over time. Unlike before, when only energy-intensive firms had to comply, now transport and building sectors will also be included. This change is crucial, as these sectors are significant contributors to Luxembourg’s overall emissions.
One notable aspect of the switch is how revenue will be handled. Under the current CO2 system, revenues go directly to the Luxembourg government. In contrast, under ETS2, financial contributions will go to the EU and then be redistributed to member states for sustainable projects.
Reasons for the Change
Wilmes cites several reasons for this shift, emphasizing that the government must align with EU obligations by 2030. There was pressure to keep the CO2 tax, but its sustainability was questionable. Fuel prices directly affect Luxembourg’s economy. Many drivers from neighboring countries fill up in Luxembourg due to lower prices. If prices diverge too much from those in France and Germany, it could jeopardize climate goals. Approximately two-thirds of fuel sales are from international customers, making this a key consideration.
Moreover, the transport sector contributes around 60% of CO2 emissions in Luxembourg. Balancing prices is crucial to ensure the country achieves its climate targets while remaining economically viable.
Simplifying Administration
Another reason for adopting ETS2 is the simplification of tax administration. Managing a national tax in line with EU emissions targets involves complexities. By joining ETS2, Luxembourg can avoid the constant legislative updates required to keep its national tax aligned with the shifting market.
Looking Forward
Recent discussions around ETS2 highlight resistance from some member states seeking concessions for specific industries. Still, Wilmes believes that the price impacts from the new system will be minor compared to the fluctuations in oil markets, affected by global events like the conflict in Iran.
Transitioning to ETS2 represents not just a shift in taxation but a comprehensive approach to lowering emissions and fostering sustainable development. The focus is now not only on reducing carbon footprints but also on fostering a collaborative European effort for climate action.
