Update expected to be released in 2024.

This guide, together with its accompanying Excel tool, aims to support shipowners looking into retrofits, with helpful guidance on considerations and operational practices that should be taken into account when selecting relevant technologies. Developed by IMO GreenVoyage2050 project.

Three-part video series on the Energy Efficiency Existing Ship Index (EEXI) regulation, which came into effect on 1 January 2023. Developed by IMO GreenVoyage2050 project.

Five-part video series on the Carbon Intensity Indicator (CII) regulation, which came into effect on 1 January 2023. Developed by IMO GreenVoyage2050 project.

This section provides access to existing inventories from different organizations on national/local restrictions on EGCS discharge water. ​

Definitions and terminology to foster discussions around climate change and potential solutions for the shipping industry’s transition to low- and zero-carbon shipping. Developed by BIMCO.

This tool enables users to calculate the bottom-up production costs of sustainable maritime fuels and benchmarks these against fossil fuels. It provides credible, third-party cost estimates that enable fuel producers, financiers and off-takers to assess fuel options on a like-for-like basis. Developed by Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.

Shippers can track fuel use and emissions, compare the carbon intensity of different shipping routes, and compare properties of conventional and alternative marine fuels. Developed by Energy and Environmental Research Associates (EERA) with funding from the US Maritime Administration’s Maritime Environmental and Technical Assistance (META) program.
