This article addresses a cross-destination research to study a key issue for the growth and competitiveness of the tourism sector,
which is the perceived environmental sustainability of a destination. Particularly, a segmentation analysis is developed to
examine potential unobserved heterogeneity across tourists regarding their perception of environmental sustainability of the
destination. 918 tourists of five Mediterranean Sea Basin cities are studied using a latent class segmentation technique. Results
show the existence of three differentiated latent clusters of tourists with low, medium and high perception of environmental
sustainability respectively, confirming the validity of this variable for segmenting tourists. Segments are also characterized by
demographics and trip-related variables. The findings provide useful information to managers to develop better sustainability
programs, tailoring their market offerings and promotion programs towards each segment more efficiently.
