  The sustainability and its key element, the environmental awareness has been known for decades, however in general can be said that in the decision making the short term economic profit is still more dominant both on the individual and company levels. In last few years the rapid growth of CO2 emission is now not just risking the human life but the flora and fauna is in heavy danger. The concerns pay more attention on their short-term profits instead of the environmental protection. First of all with the change of the leadership attitude can reach the environmentally conscious organization that can support the reduction of the emissions, so the improvement of the atmospherical CO2 concentration. In my study I’m going to present what possibilities do the companies have to reduce their emissions and how these improvements could be harmonized with the profit interests (with the reduce of electricity-, water-, and gas consumption).
