The Port of Long Beach said March 1 that shipping lines calling there last year cut thousands of tons of air pollution by voluntarily participating in the port’s Green Flag Program, which offers financial rewards for ships that reduce their speed near the harbor to decrease emissions.
The program, initiated 11 years ago as part of the port’s Green Port Policy, gives participants a Green Flag to celebrate their environmental accomplishments and dockage rate breaks to shipping lines slowing to 12 knots or less within 20 or 40 nautical miles of the port.
In 2015, 154 vessel operators met or exceeded the program’s required 90 percent participation rate at either 20 or 40 nautical miles.
Since 2005, the port has targeted emissions from ships, trucks, trains, harbor craft and yard equipment. As a result, diesel particulates are down 85 percent, smog-forming sulfur oxides are down 97 percent, nitrogen oxides are down 50 percent and greenhouse gases are down 21 percent, according to port data.
The Green Port Policy also includes other programs aimed at reducing vessel emissions, including the Green Ship Program to encourage newer vessels with cleaner engines to come to Long Beach.
The port also encourages vessel operators to use shore power, or “cold ironing,” which reduces air pollution by enabling ships to tap into landside electricity while at berth instead of running diesel fueled engines to run crucial systems.
“Our voluntary environmental initiatives have led to dramatic improvements in air quality,” Port of Long Beach CEO Jon Slangerup said. “We have surpassed our clean air goals for 2014 and nearly all of them for 2023. We continue to aspire to be the world’s first zero emissions port.”
