Conclusion • Freight transportation is profit driven • Any strategy that promotes efficiency will be considered. • So far, logistics has left a paradoxical environmental impact. • The current context may lead to several innovations. • Sustainability • A vague and mostly inapplicable concept. • Could lead to wrong strategies and technologies. • Lead to unintended consequences? • Policy driven or market forces?
