Earlier this month, Seattle and Tacoma’s port commissioners gave preliminary approval to a joint clean air strategy for the next five years. The Vancouver Fraser Port Authority has a similar Climate Action Plan and coordinates with its neighbors.
The Northwest Clean Ports emissions inventory shows big cargo vessels are the largest source of air pollution related to the seaports. If the global shipping industry were its own country, it would rank as the world’s seventh-largest greenhouse gas emitter, according to the ClimateWorks Foundation.
The 2026-2030 Clean Air Implementation Plan includes numerous steps to reduce port-related emissions, including the further build-out of shore power so that visiting cargo ships can plug in instead of idling at their berths.
Another section calls for the electrification of trucks and cargo handling equipment on the docks. But then Felleman and the other commissioners had to navigate through the tricky shoals of how to transition ocean-going vessels to cleaner fuels. It may take years for the region to reach safe harbor on that priority.
Before this month’s vote on the air pollution strategy, the port commission offices in Seattle and Tacoma were flooded with more than 100 public comments urging rejection of the marine industry’s current favorite alternative fuel, liquefied natural gas.
