Green maritime corridors will work if the National governments will believe in this measure for the decarbonisation of shipping and, above all, whether executives support the creation and operation by providing public subsidies. This is highlighted by a report defined by Global Maritime Forum, a non-profit organization essentially established shipping and shipping companies and oil companies, and the Getting to Zero Coalition, an organization promoted by the Global Maritime Forum itself and also formed mainly by shipping companies.

The document notes that now is the time when you can decree the success or failure of the establishment of corridors green seafarers and recalls that the will to promote the development of these corridors, i.e. specific routes on which operate zero-emission shipping services thanks to combined public-private initiatives, was sanctioned at the end of 2021 with the "Clydebank Declaration" signed by 21 nations as part of the COP26 in Glasgow.

In the report of the GMF and the Getting to Zero Coalition specifies that, although the private sector initiative is Important, only national governments have the resources financial and incentive measures that can allow the successful creation of these corridors. In particular, according to The report, these resources should be used to reduce the cost of adopting scalable, zero-emission technologies, thus unlocking private sector investment.

For the Global Maritime Forum and the Getting to Zero Coalition, the Best way to achieve this is through the granting of subsidies, with a direct subsidy of the national maritime transport through national budgets. Subsidies that should be directed to the purchase of green fuels, but also to ships and in support of the industrial transformation as well as to support activities research and development of enabling technologies.
