Like most businesses and industrial spheres, the global transportation and logistics sector has also come to realise the environmental aspects of some of its key functions. The issue of sustainability has come to the forefront as those who are involved in this sphere consider the way in which global transportation and logistics companies carry out their daily tasks can be transformed to minimise the harm to the environment in the long run. The need for change in existing work methodologies and policies is clear and more and more companies are showing interest in finding new ways and new structures to replace the old ones that are no longer sustainable due to the damage done to the environment and mother earth as a whole. Factoring sustainability into the company's main purpose, those in the supply chain, for example, are more likely to focus on environmentally sound practices rather than meeting demands and bemoaning the cost of these changes in operation.
