The aim of the article is to show the possible effects of implementation of the European Union climate policy on the economy and the labour market in Poland. The specified research objective and introductory literature review were the basis of the following research hypothesis: the EU climate policy will cause great uncertainty in strategic sectors of the Polish labour market and economy. The hypothesis has been examined by a method based on critical analysis of Polish and foreign literature on the EU climate policy and its economic effects. The critical analysis of literature and of available statistical data and economic forecasts confirmed the research hypothesis. It means that implementation of the EU climate policy will lead to considerable increase of uncertainty in the Polish labour market. The situation in traditional branches and sectors, such as mining, metallurgy, cement plants and traditional power plants industries is particularly worrying. On the other hand there is an expectation that in sectors based on green energy and in industries producing low emission technologies the demand for jobs will increase, but the scale of the increase is not clear and any predictions here may turn out to be incorrect.
