This paper analyzes how tourist from European countries consider environmental issues when making decisions about their their holiday plans. Modelling these decisions is a challenge because environmental concerns depends on both individiual characteristics and contextul factors related to the country or residence, such as cultural, social and economic condictions. For that reason, environmental support by households exhibit a particular type of grouped structure, where individual, firs level, are nested into countries, second level. This hierarchical structure of date are dealed with a multilevel aproach. The estimates from a Two-Level Random Intercept Logistic Model and the post-estimation analysis demonstrate that the effects of country vary randomly, and that there is significant variance in the level of tourists´ environmental support within and between countries.
