Changes in pro-environmental behaviour and its determinants during long-term period in a transition country as...

The changes in pro-environmental behaviour, whether people become more environmentally friendly or not, have been analysed very scarcely. Therefore, the aim of this paper was to analyse the changes in pro-environmental behaviour and its determinants in Lithuania as a transition European Union country comparing years 2011 and 2020. Applying Chi-Square and t test statistics, the results showed a significant increase in performance of pro-environmental behaviour in 2020. Waste sorting and purchase of environmentally friendly goods increased the most, meanwhile water and energy saving behaviour increased the least. Applying the value-belief-norm theory and leaner regression analysis, we analysed whether the same determinants influenced pro-environmental behaviour in 2011 and 2020. The results revealed that the impact of determinants differed. In 2020, the main factor of pro-environmental behaviour was the perception of environmental problems but not self-transcendence values dimension. Furthermore, self-enhancement values and awareness of behavioural consequences negatively influenced pro-environmental behaviour in 2020. Analysing the changes in these factors, an insignificant difference was observed in self-enhancement values. The changes in other factors were significant, particularly the changes in the level of environmental responsibility was the biggest. Therefore, implementation of environmental education and information programmes and various environmentally friendly public initiatives positively contributed to the enhancement of environmental awareness and pro-environmental behaviour.
