The NWPCAS first began implementation in 2008 and was later updated in 2013. It has been highly successful at advancing seaport-related emissions reduction initiatives across the participating Ports. In the 2013 strategy, two emissions intensity reduction targets were established to be achieved by 2020:
- Reduce DPM emissions per metric ton of cargo moved by 80 percent relative to 2005.
- Reduce GHG emissions per metric ton of cargo moved by 15 percent relative to 2005.
Both of these targets were achieved several years early. The reductions can be attributed to changes in international, national, and provincial regulations; port programs to accelerate the turnover of old equipment; and voluntary efforts by industry to modernize equipment and reduce emissions.
Another major success of the NWPCAS for the U.S. ports is the implementation of the Clean Truck Program, which went into effect in January 2019. The Clean Truck Program requires drayage trucks entering international terminals operated by NWSA to have model year 2007 or newer engines. Advanced emissions controls in these engines reduce DPM emissions over 70 percent. More information about NWPCAS success can be found in the annual Implementation Reports.
