Marine transport is thinking about reducing greenhouse gas emissions. What do the marine industry, and the many sectors attached to it, offer? This is the big mobilization of this end of the year through international meetings: in London this week, in Montpellier at the beginning of December, in Boulogne-sur-Mer on November 18th and 19th, under the aegis of the UN in Paris. Nausicaa the International Center for the Sea. Behind the environmental cause, we must measure the economic weight of this very broad sector and that we know very little.

In France, transport and maritime services represent more than 100,000 direct and indirect jobs. But maritime transport, which globally accounts for 90% of world trade, is just one of the many professions that are currently questioning their use of what are known as the high seas. which are no longer under the jurisdiction of States and are therefore the responsibility of all. These are about 65% of the surface of the oceans. A space today well mapped that the surface of the Moon and yet essential to the global planetary balance and from which one draws a lot of resources, in particular in biotechnologies.

Not to mention big money, we can cite the example of the French Maritime Cluster which brings together all the players, companies, the ecosystem of the sea : the organization highlights the Sustainable Development Goals in CSR policy, Corporate Social and Environmental Responsibility: companies evaluate the use of biodiversity, benefits derived from the sea (in a way). It is an important marker to better manage and protect these high seas. The sectors concerned are numerous: fishing, transport, cruise lines, shipbuilding industry, oil companies, installers of submarine cables but not only. The OECD estimates that the global maritime sector will weigh nearly 3 trillion euros in the next decade, with all the jobs that go with it. A rapid rise in power that must be controlled to no longer damage the oceans and value them at their fair value.
