The other barrier towards sustainability is a lack of knowledge (Graci, 2010; La Lopa & Day, 2010). Graci (2010) emphasizes, that environmental awareness of managers is rather low and it leads to a slow uptake for future initiatives. However, most of the managers, in this case in hotels, knows about the existence of solar power, waste battery collection as a means to save costs, but the knowledge how to dispose them is inadequate (Graci, 2010). Implementation of sustainability requires long term thinking. In contrary, capitalistic environment of tourism businesses leads to short term goals. The main problem noted by Graci (2010) is that without increase in general environmental awareness there is no incentive for tourism enterprises to implement sustainable ideas, except the ones who bring fast economic gain.
