In early 2008, the ports of Tacoma, Seattle and Metro Vancouver, B.C., adopted goals to reduce seaport-related air emissions in the region as part of the ground-breaking Northwest Ports Clean Air Strategy.
The strategy marks the first such international cooperative effort in the port community. It builds on early environmental efforts at each port, and establishes short- and long-term performance measures for reducing emissions from cargo-handling equipment, rail, harbor craft, ocean-going vessels and trucks.
2013 Strategy Update
The draft 2013 Update to the Northwest Ports Clean Air Strategy outlines 2015 and 2020 goals to further reduce maritime-related diesel emissions. The goals were developed based on the results of the 2011 Puget Sound Maritime Air Inventory.
The draft goals aim to reduce diesel emissions 75 percent per ton of cargo by 2015 and 80 percent by 2020. Combined with projected cargo growth, this will result in overall reductions of 70 percent by 2015 and 75 percent by 2020.

2011 Puget Sound Maritime Air Emissions Inventory
Maritime-related air pollution has decreased—as much as 40 percent, depending on the type—since 2005, according to the 2011 Puget Sound Maritime Air Emissions Inventory. The report provided an update to the 2005 baseline inventory.
The inventory estimated greenhouse gases, diesel particulate matter and a number of other pollutants. It focused on pollutants related to ships, harbor vessels, cargo-handling equipment, rail, heavy-duty trucks and other fleet vehicles associated with maritime activities.
See results for the Puget Sound region and Port of Tacoma (PDF). These results will help guide and focus future emissions reduction investments.
2012 implementation report
The 2012 implementation report calls out the improvements achieved by all three ports through their cooperative relationships with customers, tenants, and air and environmental regulatory agencies.
Port of Tacoma's 2012 results
71 percent of diesel-powered equipment met the 2010 performance measure through idle-reduction technologies, retrofits and engine replacements.
35 percent meet the 2015 measure.
99 percent of drayage trucks met the 2010 measure through outreach, engine retrofits or incentive programs. Learn more about our Clean Truck Program.
17 percent meet the 2015 measure.
Despite technical challenges, the Puget Sound Clean Air Agency and harbor craft operators made progress through replaced engines, shore power connections, resurfaced hulls and low-sulfur fuels.
Progress was made through conservation and recycling programs, lighting retrofits and participated in Tacoma Power's green power program, and continuing the commute-trip reduction program.
Short term - Designed to establish a bar and be attainable by 2010Long term - Raises the bar to a “reasonably achievable” level by 2015 based on available technology, economic feasibility and regional needs

We don’t prescribe specific technologies to meet the goals, but we have listed available options that could be used.
The Port of Tacoma is focusing on activities that benefit the most people right away: cleaner fuel in cargo-handling equipment and ships at berth, as well as partnering with lessees on other environmental initiatives.
