Passenger ships must use shore power when calling at ports in the EU from 2030 unless they can prove that they use another zero emission technology as propulsion.

This is part of a package called “Fit for 55” that the European Commission presented last month and which aim at reducing greenhouse gas emissions in 2030 to at least 55% compared to 1990 levels.

The package also includes an emissions trading system for the shipping industry, a maximum limit on the greenhouse gas intensity of energy used on-board and introduction of a minimum tax rate on certain fuels.
