Ports are vital components of US infrastructure and are some of the biggest drivers for the economy. They create jobs, provide critical entry points for goods used throughout the country, and enable the export of products around the world.
Port equipment is also the source of significant local air pollution and greenhouse gases (GHGs), compounded by emissions from heavy-duty trucks that travel within and beyond the port boundaries. In recognition of this, the International Maritime Organization recently established a goal of reducing GHG emissions from the shipping sector globally by 50 percent by 2050 from the 2008 level.[i]
