The aim of the paper is an attempt to answer the following questions: how to proceed with a process of the economic transformation due to adjustment of the national economy to the EU policy limiting emission CO2, what are the consequences of the enforced emission limits for the economic development and future consumption. To answer these questions the macroeconomic model has been developed and the multicriteria optimization has been applied. The multicriteria approach is an answer to the decision making problem with the two competing objectives taken into account in the EU policies: on the one hand maximum development of the national economy and on the other hand minimization of the impact on the climate warming by decreasing the greenhouse gases (GHG) emission. The analysis focuses on the macroeconomic development of the national economy under the limits imposed on the GHG emission. The long-term goal of the all economic agents is maximization of consumption. The economic sectors interact via markets of the relevant goods. The model is the mid- and long-horizon one, meaning that we consider only equilibrium trajectories due to the assumption that every year national and foreign demand for goods and services produced in all sectors equal national and foreign supply of those goods and services. The model accounts for phenomena having an impact on the economic development, such as the inertial behavior of the large-scale dynamic system, as well as social and political resistance to changes. The numerical results can serve as a reference for the real life economic policy. In assessing the duration of the technology conversion, the obtained results indicate the shortest conversion time assuming that it has been performed optimally. Three production sectors are distinguished: the sector M produces intermediary inputs, the sector C produces consumer goods, and the sector I produces investment goods. The simulation experiments are presented.
