The expected environmental benefits of implementation of the Northwest Ports Clean Air
Strategy performance measures for ocean-going vessels, cargo-handling equipment, and trucks is
a reduction in air pollutants of DPM, oxides of nitrogen (NO
x
), volatile organic compounds
(VOCs), and sulfur oxides (SO
x
), as well as a reduction in fuel consumption and emissions of
greenhouse gases (GHGs).
Ocean-Going Vessels: The At-Berth Clean Fuels Vessel Incentive Program (ABC Program)
incentivizes the use of lower-sulfur marine fuels, not to exceed 0.5% sulfur content, in auxiliary
engine operations while at a Port of Seattle berth. Switching from high-sulfur marine fuels
(~2.7% sulfur) to lower-sulfur marine fuels (not to exceed 0.5% sulfur) is expected to reduce
emissions of sulfur dioxide (SO
2
) by 95% and particulate matter (PM) by 60%.
Cargo-Handling Equipment: Exhaust retrofits installed on cargo-handling equipment reduce
emissions of particulate matter (PM) and oxides of nitrogen (NO
x
). Switching from off-road
diesel fuel (500 parts per million sulfur [ppm]) to ultra-low sulfur diesel fuel (15 ppm) reduces
emissions of sulfur oxides (SO
x
).
Trucks: A truck that meets 1994 U.S. EPA particulate matter (PM) emission standards is 6 to 2.5
times cleaner than a truck built before 1994. Similarly, a truck that meets 2007 U.S. EPA PM
standards is 10 times cleaner than a truck built between 1994 and 2006, and 5 to 60 times cleaner
than a truck built before 1994.
