In July 2021, the European Commission proposed to integrate maritime transportation into the EU Emissions Trading System (ETS) in order to cover greenhouse gas emissions from ships calling at EU ports. As part of the "Fit for 55" package, this change aims to help the EU reach net-zero GHG emissions by 2050. By putting a price on carbon and lowering emissions every year, the EU ETS provides financial incentives for stakeholders to reduce their carbon footprint, since polluters must surrender emission certificates, which cost around €90 at present.
