Facilitating cargo movement while generating less pollution, the Port of Los Angeles continues to make green growth a reality. New data released this week shows that the Port has significantly cut emissions from cargo-handling operations between 2005 and 2010, including a 69 percent reduction in diesel particulate matter (DPM) even as cargo volumes rose by 5 percent during the same period.
“The air quality in the L.A. Harbor is improving as a result of the substantial investments by the Port, its tenants and other Port-related businesses have made in recent years by purchasing cleaner equipment and participating in a variety of emission-reduction initiatives,” said Port Executive Director Geraldine Knatz, Ph.D. “Despite the challenging economy these past several years, our Port and local industry have worked hard to continue lowering emissions, and the five-year report card shows that our collective efforts are paying off.”
On a per-unit-of-cargo basis, the Port’s newly released 2010 Inventory of Air Emissions shows sulfur oxide (SOx) emissions per 10,000 TEUs have plummeted 76 percent and diesel particulate matter (DPM) emissions and related pollutants (PM10, and PM2.5)) have dropped 71 percent since the first inventory in 2005. Nitrogen oxide (NOx) emissions have fallen 52 percent, carbon monoxide (CO) 48 percent, and hydrocarbon (HC) emissions 45 percent since the baseline year. DPM is an identified toxic air contaminant and known carcinogen, and NOx and SOx are key components of smog.
Reducing emissions on a per-unit-of-cargo basis is a key objective of the Clean Air Action Plan (CAAP). When it adopted the CAAP in 2006, the Port pledged not only to reduce overall emissions but to make sure that each ton of cargo would be moved with fewer emissions in coming years. That way, even if cargo volumes continue to rise, total port-related air pollution decline. The emissions inventory is one of the most important ways the Port measures progress toward CAAP goals.
Even on a year-to-year basis, the 2010 inventory shows impressive progress. Air emissions associated with cargo handling operations at the Port of Los Angeles shows DPM emissions down by 39 percent from 2009, NOx emissions down by 25 percent, and SOx emissions down by 45 percent. Other pollutants (PM10, PM2.5, CO, and HC) showed similar declines compared to 2009. The decrease comes despite a 16 percent increase in the amount of cargo handled at the Port compared to 2009. View the 2010 Air Quality Report Card here.
When linked to a fixed amount of cargo, the decreases are even more dramatic: DPM emissions per 10,000 TEUs of cargo handled dropped 47 percent in just one year, from 1,320 pounds in 2009 to 700 pounds in 2010, SOx emissions dropped by 53 percent, and PM10 and PM 2.5 dropped by 47 percent. The other pollutants in the inventory dropped almost as much: NOx by 36 percent, carbon monoxide by 35 percent, and hydrocarbons by 30 percent.
The emissions inventory uses actual records of activity by ships, trucks, trains, cranes, and other yard equipment; data on the types and ages of the equipment; and up-to-date information on emissions factors for the various engines to calculate the actual amount of emissions produced by port activities over the year. The technique was developed in cooperation with the South Coast AQMD and the California Air Resources Board to ensure accuracy and consistency with the inventory techniques used by those agencies in other applications.
“This is the second straight year we have achieved dramatic reductions in every emissions category,” said Knatz, who cited the state’s clean fuel requirements for vessels, the San Pedro Bay Vessel Speed Reduction (VSR) program and the huge reduction in truck emissions resulting from the Port’s Clean Truck Program (CTP) as key factors in the unprecedented decline in pollution stemming from port-related operations since the start of the CAAP.
Additionally, emissions reductions have resulted from the millions of dollars the Port has spent retrofitting cargo handling equipment and harbor craft engines with pollution control devices, and pioneering the use of alternative fuels and power systems. New State air quality regulations also have helped slash emissions from the big diesel engines that power the movement of cargo at the Port.
From "Cruise Industry News" 18 August 2011
The photograph coined the Blue Marble was taken on 7 December 1972 by the crew of Apollo 17 on their way to the Moon on what turned out to be the last manned lunar mission. The iconic image was seen by many as a depiction of Earth's frailty and vulnerability. No humans since that mission have cruised that far out in space. For those of us earthbound denizens destined never set eye on it from above, we'll just have to see it up close, by exploring the Blue Marble.

Exploring the Blue Marble Mission
The cruise industry and it's partner cruise lines are tied indelibly to "things" environmental. It is where they make their living. Be it the seas they sail, the ports they visit or the passengers and crew they carry. This blog will be a brew of cruise business information, how our industry manages it's environmental obligations, information about the ports that are visited all sprinkled with bits of information from the "sciences". And yes, on occassion an opinion or two on various topics. I hope it will be informative, once in a while provocative and always entertaining. So please join me while we explore the Blue Marble.
