Since its inception, the NWPCAS has guided participating ports in their efforts to work collaboratively with industry, government, and community partners in the United States and Canada on reducing emissions. The new, 2020 NWPCAS continues and strengthens the spirit of collaboration and builds on a decade of successful implementation. The 2020 NWPCAS recognizes the urgent need to act to reduce air and climate pollution. We want to reduce, and ultimately eliminate, our contribution to diesel pollution that contributes to public health impacts and environmental health disparities in our near-port communities. And, we want to do our part to help limit global warming to 1.5 degrees Celsius (°C) this century. Last but not least, we want to position ourselves for success in a community, an industry, and a world where there is increasing focus on, and concern about, air pollution, climate disruption, and environmental injustice.
