Green Corridor

A green corridor is a specific shipping route between two or more ports along which the fuels, vessels, and bunkering and financing arrangements for zero or near-zero-emission shipping are deliberately scaled together, concentrating supply and demand to break the chicken-and-egg barrier to alternative fuels. The concept was set out in the 2021 Clydebank Declaration signed by 24 countries, with feasibility studies launched on routes such as Australia-Japan iron ore and trans-Pacific container trades. It is a coordination mechanism, not a regulation.
