Ports around the world share common challenges in reducing emissions from mobile sources, including emissions that are not directly owned by the port or that cross jurisdictional boundaries. Meaningful emissions reductions from mobile sources— including ocean-going vessels, harbor craft, trucks, trains, and cargo handling equipment -- cannot be achieved by any one entity working independently. Therefore, it is essential that ports, shipping industry partners, regulatory agencies, and non-governmental organizations collaborate with each other to reach common environmental goals. Partnerships such as the Pacific Ports Clean Air Collaborative (PPCAC) have established successful collaborative environmental initiatives that will continue into the future.
As an example, the sister Ports of Los Angeles and Shanghai have been sharing their experiences with improving environmental quality in and around the ports since 2006. Collaboration has occurred through activities such as site visits, technical workshops, technical information exchange, and staff training programs. Recognizing that their challenges are common to many other ports, the ports of Los Angeles and Shanghai co-hosted the First PPCAC Conference in Los Angeles in 2006, with support from the United States Maritime Administration, the United States Environmental Protection Agency, and the South Coast Air Quality Management District. The PPCAC Conference serves as a venue for ports, shipping lines, terminal operators, equipment manufacturers, regulatory agencies, environmental groups, and others involved in trade along the Pacific Rim to come together to share best practices, exchange ideas, and work together.
At the first Pacific Ports Clean Air Collaborative Conference, eighteen port authorities stood alongside more than thirty industry representatives for two days of presentations to discuss challenges and solutions to air pollution stemming from port operations. The conference ended with a ceremonial “commitment statement” by which the participants signaled their willingness to attend future conferences and continue the dialogue on common challenges, emerging technologies, and viable initiatives for reducing air emissions. The second PPCAC Conference, centered on climate change, was hosted by the Port of Shanghai in 2008, in Shanghai, China. The third conference, Challenges for a Sustainable Future, was held in San Pedro, California in February 2012. The fourth conference, focused on environmental impacts and assessment, was hosted by the Port of Shanghai in October 2015. The Port of Los Angeles will host the 5th PPCAC conference in March 2018.
