More than 84% of world trade is mobilized by maritime transport. The integration of land transport with ports has become essential and has had an impact in the complexity of logistics connections. The dynamic nature and importance of maritime transport have repercussions on the environment in the form of noise and air pollution or traffic congestion, among others. Despite the fact that CO2 emissions of container vessels are, comparatively, much lower than air freight emissions, a very large 18,000 TEU container vessel emits 3 grams of CO2 per tonne/kilometer. Recent studies also suggest that maritime transport contributes to 3.5 – 4% of the pollution with sulfur, a highly carcinogenic agent.
