| 摘要： | Marine vessels are a significant source of air pollutants that are associated with environmental, health, and climate change impacts (see section on Marine Transportation, Air Quality, and Human Health). There are ongoing improvements to methodologies used to quantify emissions, which will lead to a better understanding of the impact shipping has (see section on Improving Marine Vessel Emission Inventory Methods). Studies and regulations continue to try to reduce emissions and mitigate impacts; typically these activities focus on improving engine fuel efficiency (see section on Marine Vessel Fuel Conservation and Emission Reduction Options); transitioning away from highly polluting residual fuels to commercially available distillate or alternative fuels (see section on Alternative Fuels); and the promulgation of fuel and exhaust standards (see section on Fuel Exhaust Regulations Related to Marine Vessel and Port Emission Sources). |
