| dc.description.abstract | In a scenario of interdependence of companies belonging to the same supply chain and the consequent costs resulting from this relationship, whether due to the natural functioning of the chain, due to uncertainties in the relations between its members, the relevance of the reduction of resource consumption appears as a key element for the sustainability not only of companies, but of the chain as a whole. This sustainability, in the context of this research, is also environmental, focusing on the impact on the emission of CO2 gases, considering the economic, social and ecological impacts that the emission causes. From a perspective that we are far from presenting an alternative to the consumption of fossil fuels, responsible for much of the total CO2 emissions, the need to optimize fuel consumption is a temporary but necessary solution, and this optimization has a reduction of uncertainties. In this way the objective of this work is to determine how much investment in information technologies is able to reduce the emission of the CO2 gases, through the reduction of uncertainties. To achieve this goal, a case study with two companies was developed, collecting data of fuel consumption and investments in information technology. As a method of data analysis the multiple-squares least squares regression method was adopted. The results demonstrate the investment relation in information technology’s department with the reduction of CO2 emission related to the variables of Manpower and Communication in Company 2. The use of information by the information technology departments analyzed was shown to be inversely proportional to the emission of CO2. Finally, the research shows how the influence of investment in information technology impacts on the reduction of fuel consumption, presenting a table showing the impact of the technology information’s investment in the CO2 emission resulting from the company's operations. | en |
