Sustainable development is a global problem and therefore a global response is required. We cannot protect the environment in a way that prevents economic development, but we need to focus on how to achieve sustainable development. The term sustainable development was mentioned at a conference in Rio de Janeiro in 1992. The success of the sustainable development concept is possible on the global level only by achieving the main political goals and by implementation of social changes. Sustainable development can be defined as a relationship between changeable economic systems, which human creates, and more variable ecological systems that are inert and these two must be in an ecological balance. Without accepting responsibility for the success of sustainable development concept at the local level, sustainable development cannot give results globally as well. The concept of ecological footprint was developed by William Ress who is credible for that name. The ecological footprint is described as a tool to measure the amount of soil and water needed to support the material standard of a particular population using prevailing technology. The ecological footprint is measured in hectares and shows how much each individual, city or country, needs to meet their needs in food, housing, energy, transport or waste management. The current state is such that we should have 1.8 capacity of the Earth to provide resources and ecosystem services which are currently used. Ecological imprint implies arable land, i.e. biocapacitiy required for crops, pastures, inhabited areas, fishing and forest areas. This study was conducted on students from University North. Results indicated that understanding or awareness of the existence of the sustainable development concept has a direct impact on the application of the principles that are embedded in the definition of sustainable development. By researching a business entity, it comes out that most of them have uniform application of the selected and tested habits, regardless of the understanding degree of the sustainable development concept.
