This paper brings, as an element of novelty and originality, a strategic feasibility study, in the form of a logical analysis related to the proposed objective, with particularization to the area of the EFTA plus the UK and Ireland. We tried to achieve an overall picture of a sustainable and prudent transition at the macroeconomic level, but also at the microeconomic and local levels, with specific values of ecological and energy-smart villages/towns. The convergent actions of the signatory states of the climate treaty COP-26/2021—Glasgow, UK are to improve the logistics and financing of the large-scale replacement of fossil fuels used in the economy and lives of human society. Various strategies have been discussed to address the energy mixes that could be used in the transition phase in stages and combined-cycle natural-gas plants, conditioned by the implementation of CCUS technology. The preliminary stage will focus on the provision and implementation of modern technologies for the production of electricity in photovoltaic and wind power. Starting with the 2030s, the industrialized production of blue and green hydrogen is expected; the first is expected to be obtained from the chemical synthesis of natural gas with the separation and storage of residual carbon from chemical reactions, and the second directly from ocean water through the phenomenon of H2O electrolysis. As a basic legislative element, the strategy aims to refine the idea of a carbon tax at the border or at the user, in order to discourage the use of fossil fuels.

Digitalization has become a watchword in all areas of economic and social activity, and its integration has become a necessity for every state worldwide. If a few years ago we were talking about technological innovation and cutting-edge technologies we are now talking about digital technologies, robotics, big data, and artificial intelligence, and future industrial production will develop in symbiosis with modern information and communication technology. The paper aims to show the impact of digitalization on macroeconomic indicators, including labor productivity, value-added, and value of exports of goods and services, and in this regard, we have built an econometric model to see how digitalization and the evolution of macroeconomic indicators work, and how they will influence the degree of growth and economic development. The research results verify the hypotheses we started from, namely that there is a positive and strong correlation between digitalization and productivity, as well as between digitalization and value-added, and that there is a positive, yet weaker correlation between digitization and exports. The impact of digitalization on macroeconomic indicators extends beyond the theoretical and practical implications, as they influence both the decision-making process of the companies’ management and national and European economic policies.
