One of the ambitions of the 2023 IMO Strategy is the uptake of zero or near-zero (ZNZ) technologies, fuels and/or energy sources to represent at least 5%, striving for 10%, of the energy used by international shipping by 2030. To meet this target, some of the proposed measures in the potential basket of mid-term measures work with a feebate mechanism. ZNZ fuels are, however, it is not precisely defined yet and it is still unclear how the compensation as part of the feebate mechanism should be determined. In this context, CE Delft has analysed possible parameters of a feebate mechanism at the request of the Dutch Ministry of Infrastructure and Water Management.
