Leverage ETS for shipping to drive decarbonisation investments: The Emission Trading System (ETS) is an essential tool to reach EU climate targets and internalise the costs of emitting GHGs. It should be maintained and strengthened to ensure a carbon price that shifts investment away from fossil fuels, unlocks long-term industrial investment and reduces exposure to supply disruptions. The ETS generates significant revenues, a share of which should be used to support the production of e-fuels in the EU.
