EPA Releases National Assessment of Strategies to Reduce Air Pollution at Ports

A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies.  Implementing these approaches, the report finds, would reduce greenhouse gas and other harmful emissions from diesel-powered ships, trucks and other port equipment.

“The National Port Strategy Assessment:  Reducing Air Pollution and Greenhouse Gases at US Ports” examines current and future emission trends from diesel engines in port areas, and explores the emissions reduction potential of strategies like replacing and repowering older, dirtier vehicles and engines, and deploying zero emissions technologies.

US ports are set to expand significantly as international trade continues to grow, and the size of ships coming to ports increases.  This growth means more diesel engines at ports emitting CO2, fine particulate matter, NOx, and other pollutants that contribute to serious health problems including heart and lung disease, respiratory illness, and premature mortality. Children, older Americans, outdoor workers and individuals with respiratory and heart conditions can be especially vulnerable.  Many ports are located in areas with a high percentage of low-income and minority populations, who bear the burden of higher exposure to diesel emissions.

Accelerating retirement of older port vehicles and equipment and replacing them with the cleanest technology will reduce emissions and increase public health benefits.  For example, the report found replacing older drayage trucks with newer, cleaner diesel trucks can reduce NOx emissions by up to 48%, and particulate matter emissions by up to 62%, in 2020 when compared to continuing business as usual.  In 2030, adding plug-in hybrid electric vehicles to these fleets could yield even more NOx and PM2.5 relative reductions from drayage trucks.

The new assessment supports EPA’s Ports Initiative’s goals to reduce air pollution and greenhouse gases, to achieve environmental sustainability for ports, and improve air quality for all Americans working in and living near our nation’s ports.  Through this initiative, EPA is engaging a wide range of stakeholders including ports and port operators, communities, tribes, state and local governments, industry, and other technical and policy stakeholders.  EPA developed this national scale assessment based on a representative sample of seaports, and the results could also inform decisions at other seaports, Great Lakes and inland river ports, and other freight and passenger facilities with similar profiles.
