This is a graph including two pie charts. In the left charts where 34 of 53 students most chose  'relevant government departments' when they are asked 'who should be responsible for the hotel's sustainability development' and only 2 of 53 students thought entrepreneurs should do this.

​

While in the right chart, 20 out of 49 which stands for 'Necessarily' keeps almost the same percent with 18 out of 49 which selected 'probably' when they are asked if it is necessary to apply sustainability in hotels.

​

It is concluded that students thought 'sustainability' should be a task finished by the relevant government instead of business companies or other social members while students did not clearly know whether sustainability has to be applied in the hotels' industry so that their sense of sustainability is not defined clearly by themselves.
