摘要：	Ports are a vital part of the United States economy, with seaports, Great Lakes ports, and inland river ports serving as gateways for moving freight and passengers across the country and around the world. Seaports alone account for more than 23 million jobs and seaport cargo activity accounts for 26% of the United States economy. The U.S. Army Corps of Engineers estimates that bigger Post-Panamax size ships that currently call at U.S. ports will dominate world trade and represent 62% of total container ship capacity by 2030.2 As our nation adapts to meet these emerging economic and infrastructure demands, it is critical to understand the potential impacts on air pollution, greenhouse gases (GHGs), and the people living, working, and recreating near ports. The U.S. Environmental Protection Agency (EPA) developed this national scale assessment to examine current and future emissions from a variety of diesel sources operating in port areas, and to explore the potential of a range of available strategies to reduce emissions from port-related trucks, locomotives, cargo handling equipment, harbor craft, and ocean-going vessels.3 Diesel engines are the modern-day workhorse of the American economy, and although they can be reliable and efficient, older diesel engines can emit significant amounts of air pollution, including fine particulate matter (PM2.5), nitrogen oxides (NOx), air toxics, and carbon dioxide (CO2), which impact human health and the planet.
