further improving the energy efficiency of ships; developing additional means – such as market- based measures – to further reduce emissions of greenhouse gases from ships; preventing and controlling the transfer of invasive aquatic
species through ships’ ballast water and ships’ hull fouling, which are estimated to cost around USD 100 billion per year; and addressing the technical,
operational and environmental aspects of the ever-increasing size of ships. Projected annual CO2 emissions from the shipping sector
