Sea transport accounts for most of the European Union's external and internal commerce. The EU is the world's third-largest importer of fisheries and aquaculture products and the fifth-largest producer. Maritime borders make up more than 70% of the Union's external borders, and hundreds of millions of travelers pass through European ports each year. The security of Europe's energy supply is heavily reliant on marine transit and infrastructure. The significant expansion of EU Member States' fleets, as well as suitable port infrastructure, contribute to a well-functioning energy market and supply security, and hence to European residents' and the European economy's overall well-being.[1] The Arctic region is therefore a vital new area for the EU to work towards and a new strategy for the Arctic region that matches with the European Green deal was established in late 2021.[2]
