Reducing Pollution From Maritime Engines

Roughly 23% of the diesel exhaust in the Puget Sound region comes from the maritime sector. This sector includes diesel engines used in and around our region’s ports - powering drayage trucks, cargo-handling equipment,* ferries, tugboats, shipping vessels, etc.

We help businesses, government agencies and ports reduce diesel emissions and fuel costs through:Graph of diesel emission sources.

  • Best practices
  • Clean or alternative fuel
  • Engine upgrades
  • Repowers (engine replacement)
  • Retrofit technologies (exhaust retrofits and idle-reduction)
  • Vehicle replacements

*Note: For emissions inventory purposes, our agency includes cargo-handling equipment in the maritime sector and not in the off-road sector.
