Most people think that airplanes produce more CO2 than ships, given the volume of air traffic during any given day. This is incorrect. Airplanes only produce 2.3% of the carbon dioxide pollution on earth. Ships produce 4% of the total CO2 in the atmosphere. Ships are more disastrous to the ecosystem and are a bigger contributor to global warming. The MS Beluga Skysail aims to change things for the better.
