A critical component of regional freight transportation, heavy-duty trucks represent 1 percent of maritime industry diesel emissions at the Port of Tacoma. To reduce this impact, the Port Commission recently authorized a market-based programme to reduce over-the road emissions.
The Port of Tacoma Truck Emissions Improvement Programme is designed to improve air quality, increase gate efficiency and be environmentally sustainable. The programme, which is fee-free, was developed collaboratively with the trucking industry and other Port customers. According to a 2008 Port of Tacoma truck fleet study, 86 percent of the heavy-duty drayage trucks serving the Port meet the 2010 emission standards. The programme’ s aimed at encouraging the remaining 14 percent to modernize their vehicles.
