This article examines the pro-environmental behaviour of EU citizens and the potential connection with their attitudes towards common environmental legislation and environmental standards. It analyses factors of the pro-environmental behaviour of EU citizens and their attitudes towards EU environmental legislation and helping non-EU countries improve their environmental standards. The article uses cross-sectional regression analysis based on Special Eurobarometer survey. Respondents show a mostly positive view of EU environmental protection legislation and standards enforcement. Respondents with pro-environmental behaviour in their daily life are significantly more in favour to common environmental legislation and standards. Women, managers, and those interested in political affairs are more positive as well.
