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:
- 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.

Maritime Emission Inventory
- Description: Partner with the Maritime Air Forum members to develop an emission inventory of maritime-related diesel equipment operating within the greater Puget Sound region. This inventory helps determine where to focus our efforts in reducing diesel emissions.
Marine Engine Replacements
We are providing incentives to replace 12-19 engines on 6-8 harbor vessels currently operating in the Puget Sound.
- Project Period: Currently Open
- Funding: U.S. Environmental Protection Agency (EPA)
Crowley Shore Power
Crowley installed landside shore power at their Tacoma location, allowing them to plug-in three tug boats to shore power to avoid running their diesel auxiliary engines when docked.
- Air Pollution Reductions:
- Particulate Matter (PM 2.5) - 0.08 tons per year
- Nitrogen Oxides (NOx) - 3.5 tons per year
- Carbon Dioxide (CO2) - 311 tons per year
- Project Period: 2017 - 2018
- Funding: Washington State Department of Ecology
- Partners: Crowley
Auxiliary Engine Replacements
Eight private businesses and public agencies replaced 16 auxiliary engines on ten different vessels. The vessels' size ranged from tug boats to cruise ships.

Vessel Repower & Sustainability Project
Island Tug and Barge replaced seven engines (four main engines and three auxiliary engines) on two of their tug boats. They also upgraded two engines on a third vessel.
This project included other elements, such as internship opportunities with Seattle Central Community College, a Harbor Vessel Workshop to talk with marine businesses about pollution reduction, stack testing, and the development of a white paper comparing the effectiveness of several harbor craft sustainable projects.
