To be counted as a green corridor for the purposes of this tracker, initiatives must meet the Getting to Zero Coalition definition of being “a route on which the feasibility of zero-emission shipping is catalysed by public and private action”. Specifically, they must:
- Work toward the use of zero-emission fuel or energy for primary ship propulsion,
- Support the commercialisation of non-commercial fuels or energy sources in shipping,
- Feature a high level of cross-value chain collaboration, including close engagement and input from national/regional governments,
- Call themselves a green corridor from their point of initiation,
- Focus on zero emission ocean-going vessels.
