The aim of this article is to present the aims and structure of the European Green Deal with special notice on actions planed within „blue economy”. The maritime sector will have to play a central role in alleviating the multiple demands on the EU's land resources and tackling climate change by improving the use of aquatic and marine resources.

Marine governance is an essential way of achieving the objectives of sustainable development. It ought to be understood as the process of planning, as well as decision-making and management at the national and regional levels taking into account the global ocean as an ecological unity. The process of decision-making is closely interrelated with the regional and transnational cross-border cooperation.

MSP Directive requires all coastal EU Member States to prepare cross-sectoral maritime spatial plans by 2021. The development of spatial plans for Polish marine areas was started in 2013.

Marine casualties, at sea or in port waters, are not only caused by large passenger or cargo vessels, which, due to their size, may have difficulty in giving way or stopping safely, but also small vessels such as marine yachts or jet skis, which have a high manoeuvrability but mistakes made when navigating or manoeuvring by the operators of these vessels can be serious. The aim of this article is to analyze the collision of two such crafts in port waters in the aspect of criminal liability of the perpetrator of the accident for causing it.
