The European Green Deal is a strategy aimed at making Europe climate neutral in 2050. This work plan consists of several initiatives: European Climate Law, European Climate Pact, adaptation strategy, Farm-to Fork strategy and task to increase the EU 2030 climate target towards 55%. 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.

This paper discusses the impact of the European Green Deal policy on the clean energy transformation in the European Union, focusing on the generation of electricity reaching a significant milestone for the EU in 2020 – renewable energy sources for the first time in history surpassing combined fossil fuels in the generation of electrical energy. This achievement, although partially influenced by the exceptional circumstances of the COVID-19 pandemic and the electricity demand shock, is primarily an effect of the Clean Energy for all Europeans Package implementing the European Green Deal strategy designed to position the EU as a global leader in the green transformation, leading by example and turning climate challenges into a growth opportunity, and in doing so presenting an optimistic policy perspective for a global transformation towards a 100% renewable energy world, thus supporting mitigation of the global-warming threats by significantly cutting greenhouse-gas emissions. With the immediate effects of the 2018 recast Renewable Energy Directive (2018/2001/EU) and other related clean-energy policies under the umbrella of the European Green Deal, coal and lignite electric generation has fallen in 2020 by as much as 22% (87 TWh) and the nuclear generation has dropped by 11% (79 TWh), with natural gas to a much lesser extent, yet still noting an annual drop of 3%, while renewables grew, surpassing the combined fossil fuels electricity output in the whole of the EU. This is an impressive result confirmed in late 2021 and a hallmark of the European Green Deal initial success, the sustainability of which is yet to be assessed in the coming years, especially in view of the recent international situation of major destabilization. In this context, it should be added that although the newest 2022 Global Energy Review report by the IEA confirmed in 2021, the highest global CO ₂emission level in history (following the post -pandemic economic rebound and also due to the gas-price crisis of late 2021 causing gas-to-coal shifts in electricity-mix, which in the EU, resulted in a 7% relative annual emissions increase), Europe’s emission level has remained in a diminishing trend following the European achievements of 2020, with an overall CO ₂ emissions decrease of 2.4% in comparison with the level of 2019. Most likely, however, the 2021 gas-price crisis was only a mere prelude to a much more robust long- -term perturbation that will be expectedly due to the war in Ukraine and the necessary sanctions policy, especially impacting the energy market and probably further hampering the green-transition process jointly with other economic factors.

The article presents the main elements of the European transport policy and the issues prevailing in the public debate in the last decade, i.e. 2010-2020. In particular, it analyses the challenges for European transport resulting from the need to combat climate change and to ensure a high level of environmental protection and safety, while taking into account the progressing technological revolution. The main assumptions of the European Green Deal, which aims to achieve climate neutrality by the European Union by 2050, are presented. The example of maritime transport serves to describe how various transport sectors are being brought into line with EU climate targets.
