With the growing success of the populist radical right in Europe, the number of cases where representatives of the populist radical right speak out on environmental issues is also increasing. The aim of this diploma thesis is to characterise the relationship of the populist radical right in Slovakia to environmental issues. This relationship is explained using the concept of nationalism, the concept of globalisation and the concept of populism. The empirical analysis is based on a content analysis of the official promotional materials of the analysed Slovak parties. The results of the content analysis show that Slovak populist radical right parties work with the aesthetic, symbolic and materialistic dimensions of nature in their materials. From the perspective of globalisation, the promotional materials claim that global measures against climate change are destroying Slovak agriculture, economy and traditional countryside. The promotional materials also claim that these measures are being exploited by elites who are served by scientists and bureaucrats from the European Union. In terms of populism, the representatives of the analysed parties link environmental problems with the people and organisations they want to criticise (e.g. non-governmental organisations or the Roma community) and at the same time demonstrate their authenticity that their parties are the only true protectors of Slovak nature. Last but not least, the results show that Slovak populist radical right parties approach environmental issues differently when they are part of the government and differently when they are not part of the government.
