Ecological footprint (EF) gives us clues about sustainable life and appears before us as an important indicator showing the burden of humans on this planet. The purpose of the present study was to examine the behaviours and the variables that affect these behaviours of doctor candidates, which represent an important profession in the world and in our country in this respect. The study was designed in cross-sectional fashion and was conducted in December 2017 with medicine faculty students. The dependent variables of the study were EF scores and the scores of the EF sub-components like food, house, travel, and other, and the carbon footprint (CF) score; and the independent variables were age, gender. EF score median (min-max) value of the study group was computed as 2.90 (1.78-7.09) kha, and the CF score median (min-max) value was computed as 11.69 (5.99-40.19) t. The travel component median (min-max) value was 0.93 (0.06-4.82) kha. The highest contribution to the EF was made by the transportation sub-component. In the light of the data of the present study, it was concluded that the medicine faculty students had information on the EF concept. This information must be increased with training that will be provided in the future.
