U.S. and international container shipping ports are among the biggest sources of air pollution and greenhouse gas emissions, because of their reliance on diesel fuel. But progress toward reducing harmful emissions by switching to clean alternative fuels is gaining momentum
worldwide, according to a new study.
"Container Ports and Air Pollution," published by Energy Futures Inc., found that natural gas is currently the leading alternative fuel for goods movement at U.S. container ports, while hybrid electric vehicles are gaining popularity in Asia.
The 77-page report presents findings from a 10-month-long study that included on-site visits to evaluate air pollution control efforts at top container ports in the U.S., Europe and Asia. The new Energy Futures study updates and expands on a report titled "U.S. Container Ports and Air Pollution: A Perfect Storm," which was published in February 2008. That study identified environmental protection alternative fuel programs at each of the top 10 U.S. container ports, including their use of natural gas, biodiesel or hybrid electric vehicles.
"A key premise of our studies of air pollution in the container shipping industry is that alternative fuels offer viable options for use in goods movement operations to replace polluting fuels that are derived from oil," says James S. Cannon, president, Energy Futures. "These clean-burning fuels are known to work well in port goods movement, and there is great promise that they can be more widely used in the shipping supply chain."
Cannon unveiled the new report to an international audience in a speech Wednesday at the GreenPorts 2009 Conference in Naples, Italy.
Included in the new report are updated profiles that showcase air pollution control efforts at the Ports of Los Angeles and Long Beach, Calif.; the Port of New York and New Jersey; the Port of Savannah, Ga.; the Port of Oakland, Calif.; the Port of Hampton Roads, Va.; the Port of Seattle, Wash.; the Port of Tacoma, Wash.; the Port of Houston, Texas, and the Port of Charleston, S.C. Case studies at the Port of Rotterdam, the Netherlands, and the Port of Hong Kong are also included.
The research clearly shows that 2008 was the busiest year yet for innovative new environmental efforts, particularly at the top U.S. container ports. Many ports are taking action to reduce the pollution they generate through alternative fuel and advanced technology programs. In 2008, for example, regional truck programs were launched at the three California ports - Los Angeles, Long Beach and Oakland - that are expected to deploy thousands of natural gas-powered goods movement trucks during the next few years.
Cannon explained that the U.S. is the largest importer of containerized goods, yet the millions of containers handled at U.S. ports annually comprise only about 10 percent of the global container trade. The study documents significant progress during 2008 in environmental programs affecting international goods movement.
