Several Problems of Low-emission Economy

First of all, the paper explains the meaning of climate sustainability and the parallel understanding of the category of sustainable development in the EU as a concept of total decarbonization of the economy. Secondly, it shows a great impact of Europe 2020 strategy and the latest package 2.0 for the period to 2030 on the Polish industry and society, due to the specific structure of energy balance and high costs of climate change mitigation. Thirdly, the paper shows the possibilities of the technological change in the energy sector in a broad sense that led to the low-emission economy and at the same time which are feasible and economically acceptable. Apart from renewables, energy efficiency, coal substitution to gas and cogeneration, a few efficient technologies exist which are a climate ‘rescue' being consistent with the low-emission economy as well as securing minimum prospects for coal. Although the possibilities of CO2 reductions in the process of coal combustion are especially limited, moderate chances can be seen in the conversion process of coal to gaseous and solid forms
