Abstract
Establishing a recognition system for sustainable freight transport is a process of change that requires the commitment of those involved and application of good practices. The pressures from consumers and competitors do not allow greater engagement with economic, social, and environmental aspects, and the maintenance stages require a long-term effort to obtain credibility, because the participation of external members of society in the evaluation contributes to reduce the influences and uncertainties of the recognition criterion. In light of the difficulties of establishing a green supply chain, we propose a method with multiple approaches with an emphasis on fuzzy logic. The purpose is to reduce the indecision of judgment, to debug the qualitative variables and to reduce interference from competitors. The procedure was applied to six companies that have carbon reduction programs, but we found that firms with a core business in transport had greater success in the transition to low carbon operations than contractors or shippers. The certification levels allowed visual contact between consumers and the company, making it possible to monitor sustainability actions in freight transportation operations and the competitiveness to achieve higher labeling levels.
Highlights
The main recent change in supply chains is the absorption of the premises of sustainable freight transport systems by companies, which will be essential for the maintenance of activities from extraction to the delivery of the product to customers in B2B or B2C.The challenge is the transfer of materials, in the appropriate quantity and quality, with excellent service among the different modes of transport, with less impact on the environment [1,2]
The interest in the development of sustainable practices in freight transport has been due to external pressures and the large participation of transport in carbon emissions and air pollutants
The participation of external experts avoided distortions in the decisions to invest in one aspect to the detriment of another
Summary
The main recent change in supply chains is the absorption of the premises of sustainable freight transport systems by companies, which will be essential for the maintenance of activities from extraction to the delivery of the product to customers in B2B or B2C.The challenge is the transfer of materials, in the appropriate quantity and quality, with excellent service among the different modes of transport, with less impact on the environment [1,2]. The transport sector is responsible for 24% of the world’s energy-related CO2 emissions [9], with a high concentration of pollution in urban areas, impacting air quality, with serious effects on health and human ecosystems [10]. Traffic air pollution is associated with several health problems, such as obesity and diabetes, being partly responsible for low productivity and social problems [13,14,15]. These problems cause the need to develop skills for anticipating events in order to assess the risks related to the non-application of good
