A blueprint for assessing the feasibility of green shipping corridors has been jointly developed by the Maersk Mc-Kinney Moller Center for Zero Carbon Shipping with consultants McKinsey & Co.

The 100-page document provides a step-by-step guide to demonstrating the feasibility of and designing green corridors.

Establishing green shipping corridors, where vessels can run on alternative fuels on routes from one place to another, will be an essential step to decarbonising shipping, the centre said, but “there is still limited knowledge on how to take green corridor concepts from ideas to implementation”.

The blueprint aims to provide a framework for a deeper evaluation of selected green corridor scenarios to determine their technical, economic and regulatory feasibility and identify actions to mitigate potential gaps and risks, it said.

The seven-chapter guide includes a methodology that outlines key questions and provides analysis that all members of a supply chain need to consider to assess a green corridor’s feasibility, whether they are coming from a ship or cargo owning, fuel production, bunkering, financing or port or consumer's viewpoint.

The Maersk Mc-Kinney Moller Center said the blueprint is a living document with illustrative templates of resources required that will be refined over time as more knowledge and hands-on experience of building green corridors is gained.

“The blueprint brings together all the analyses in the final chapters and highlights the key actions that must be taken to turn the corridor from an idea to reality,” the centre said.
