Protecting American Health from Global Shipping Pollution

"Emission Control Area" Means Healthier Air for Millions of Americans

WASHINGTON, March 30 /PRNewswire-USNewswire/ -- A new report released today finds that more than 87 million Americans live in port areas that are not meeting federal health-based air quality standards. The report, Protecting American Health from Global Shipping Pollution, documents the public health effects associated with air pollution from global shipping, including container ships, tankers, cruise ships, and bulk carriers. The report, released by the American Lung Association, Environmental Defense Fund, National Association of Clean Air Agencies, and Puget Sound Clean Air Agency, is available online at: www.edf.org/documents/9466_ECA_report_March2009.pdf.

The coalition strongly encourages and supports action by the U.S. government that to apply to the International Maritime Organization (IMO) for the establishment of an Emission Control Area: an area where rigorous pollution limits apply to global shipping activity. Environmental Protection Agency Administrator Lisa Jackson will announce the U.S. application to the IMO during a noon news conference today in Port Newark, NJ. Foreign-flagged vessels make 90 percent of the ship calls on U.S. ports. Leading researchers estimate that shipping pollution is associated with 60,000 global deaths annually. EPA's Analysis shows that the establishment of an Emission Control Area could dramatically reduce lethal particulate pollution in U.S. coastal communities.

COALITION STATEMENTS

Statement of Captain Charles D. Connor, U.S. Navy (Ret.), American Lung Association President and CEO: "In my career as a U.S. Navy Captain, I saw firsthand the staggering amounts of pollution that cruise ships, container ships, tankers and other ocean-going vessels released into the atmosphere. These ships dock at more than 100 ports along our coastline and along navigable waterways far inland. Their smog- and soot-forming emissions threaten the health of those living far from our nation's maritime ports."

Statement of Vickie Patton, Deputy General Counsel, Environmental Defense Fund: "The dangerous air pollution from these floating smokestacks is a serious health threat to tens of millions of Americans who live and work in port cities. Cleaning up these big ships will chart a course for cleaner air and healthier communities."

Statement of Bill Becker, Executive Director, National Association of Clean Air Agencies: "These big ships are big emitters. We need all hands on deck to help state and local air pollution control officials reduce the pollution from global shipping and restore healthier air in our communities."

Statement of Dennis McLerran, Executive Director, Puget Sound Clean Air Agency: "Approval of an Emission Control Area for the coasts of North America at the earliest possible date will save hundreds of lives across the U.S. and Canada. In the Pacific Northwest, ocean-going ships travel hundreds of miles inland before reaching the Ports of Seattle and Tacoma and we will see significant air quality improvements in a wide area of Washington State when an ECA is put in place."

BACKGROUND

An Emission Control Area, or ECA, would provide the strongest clean air standards available under international law. It would dramatically improve fuel quality and reduce smog-forming oxides of nitrogen for all ocean-going ships in the exclusive economic zone of the United States, an area that typically extends about 200 nautical miles from the coast. To secure these vital protections, the U.S. government must submit an application to the International Maritime Organization (IMO) demonstrating the need to prevent, reduce and control global shipping emissions. The IMO would review the application at its July meeting and take final action on the U.S. request in 2010.

Container ships, tankers and the other large sea-going vessels that dock at more than 100 U.S. port cities burn low grade "residual fuel" or "bunker fuel" that is a major source of air pollution, including the formation of particulate pollution. Residual fuel contains sulfur levels 1,800 times greater than U.S. law allows for other diesel engines. A recent study by two leading researchers on shipping pollution, Corbett and Winebrake, shows shipping-related particulate pollution contributes to approximately 60,000 global deaths annually, with impacts concentrated in coastal regions on major trade routes.

In October 2008, the IMO, with active participation from the U.S. government, adopted new baseline global emission standards for ocean-going ships and their fuel. The IMO also provided for more rigorous, heightened protections in designated Emission Control Areas (ECAs). The fuel used to power these ships currently contains about 27,000 parts per million (ppm) of sulfur. In an ECA, the sulfur in fuel will be limited to 10,000 ppm in August 2012 and then to 1,000 ppm in January 2015.

Within an ECA, ships must also achieve an 80 percent reduction in smog-forming oxides of nitrogen starting in 2016.

EPA air quality analyses shows the pollution reductions required in an ECA will reduce exposure to lethal particulate pollution for millions of Americans.

Ocean-going ships contribute to unhealthy air quality across the United States. According to EPA, in 2001, these large ships emitted approximately:
- 745,000 tons of smog-forming oxides of nitrogen, a precursor to ground-level ozone. Ozone can aggravate asthma and decrease lung function in addition to other health effects;
- 450,000 tons of sulfur dioxide, a key contributor to acid rain that can also be transformed into lethal particulate matter; and
- 54,000 tons of fine particulates, microscopic sized particles, which can be breathed deep into the lungs, bypassing the body's defense systems. They are implicated in thousands of premature deaths each year. Other harmful health effects also result from breathing fine particulates.

Ocean-going ships are also responsible for about 3 percent of the world's total greenhouse gas pollution.

Keep on Trucking - with Lower Emissions through EPA's $50 Million Clean Diesel Funding

To improve air quality and protect public health, EPA today announced the first $3.4 million in funding for clean diesel projects under the $50 million Diesel Emission Reduction Program. This campaign makes awards to save fuel and lower greenhouse gas and diesel exhaust emissions from the country's existing fleet of 11 million diesel engines.

"This fall, EPA is paving the way for clean diesel progress," said EPA Administrator Stephen L. Johnson. "These grants encourage technologies that will help truckers save over $72 million in fuel costs per year and lower their environmental impacts."

Three organizations received $3.4 million for small trucking firms to lower fuel costs and shrink their carbon footprints through innovative loans and rebates. The organizations receiving funds under the national diesel program are: the Community Development Transportation Lending Services, Washington, D.C.; Cascade Sierra Solutions, Oregon; and Owner-Operator Independent Drivers Association, Missouri.

EPA will also begin disbursing $14.8 million for State Clean Diesel programs. All 50 states will receive funds, and 35 states will put matching resources toward the program. Later this fall, $27.6 million in grants will be distributed by EPA's ten Regional offices. Finally, grant awards for emerging technologies totaling approximately $3.4 million will be announced this winter.

Diesel engines emit 7.3 million tons of smog-forming nitrogen oxides and 333,000 tons of soot annually. This pollution is linked to thousands of premature deaths, hundreds of thousands of asthma attacks and millions of lost work days. EPA's new diesel engine standards will significantly reduce emission from newly manufactured engines, and these grants will lower emissions from the diesel engines already in use through clean innovative technology.

California Proposes New Regulations to Reduce Diesel Pollution at Ports

The California Air Resources Board Chairman Mary Nichols highlighted two port-related emissions reductions programs on Wednesday, Dec. 5th. If passed by the full Board later this week, the programs will dramatically reduce diesel particulate matter pollution from ships and trucks throughout the state by 2014.

The first regulation requires operators of certain types of ocean-going vessels to shut down their diesel auxiliary engines while docked at the state's busiest ports in favor of using shore-based electrical power. The second regulation is aimed at cleaning up emissions from the aging fleet of dirty diesel trucks that hauls goods around the clock to and from ports and rail yards throughout the state.

"These first-of-their-kind measures will continue our work to slash port-related emissions," Nichols said. "Residents from San Pedro to Oakland will breathe easier as a result of our aggressive actions to clean up diesel emissions from ports throughout the state. We owe it to the long-suffering ports communities to continue our quest of reducing all the emissions we can from ships, trucks and trains."

ARB adopted strategies in December 2005 that require cleaner engines in cargo handling equipment and clean fuel on ships.

Combined with the measures before the Board this week, ARB regulations will reduce diesel particulate matter emissions from container and cruise ship terminals by almost two-thirds by 2010, and by an estimated 75 percent by 2014. Overall diesel soot emissions will decline by 1,800 tons per year in 2014.

Shore Power
The new regulation will require certain fleet operators of container, passenger and refrigerated cargo ships ("reefers") to turn off their auxiliary engines -- which power lighting, ventilation, pumps and other onboard equipment -- while a ship is docked for most of its stay in port. The rule will affect almost 95 percent of the ship visits in these three categories.

Once docked, operators would then be expected to receive their electricity from shore-based sources or meet percentage reductions through other means. Ports affected by the regulation are those most visited: Los Angeles, Long Beach, Oakland, San Diego, San Francisco and Hueneme in Ventura County.

A 2005 ARB exposure study at the ports of Los Angeles and Long Beach shows that more than two million people live in areas around the ports with predicted cancer risks of greater than 10 in a million due emissions from docked ocean-going vessels. From that study and other data, ARB estimates that about 61 premature deaths per year can be attributed to exposure to diesel exhaust generated from ships in port.

Container, passenger and reefer vessels call at California ports almost 6,000 times each year, accounting for nearly 85 percent of the emissions from all docked ships. In 2006, approximately 1.8 tons per day of diesel particulate matter and 21 tons per day of oxides of nitrogen (NOx), a key ingredient of smog, were emitted from the diesel-fueled auxiliary engines of docked ships. The regulation is expected to reduce diesel and smog-forming emissions from docked container, passenger and reefer ships by nearly 50 percent relative to levels otherwise expected to be emitted in 2014, and 80 percent by 2020.

Next year, ARB expects to introduce a similar rule that will reduce emissions from bulk ships, tankers and vehicle carriers.

Port Trucks
ARB staff estimates that California has about 20,000 port or "drayage" trucks that frequently visit the ports and rail yards and have the greatest impact on local air quality. Drayage trucks are a significant source of diesel particulate matter, contributing three tons per day statewide. With regards to the smog precursor NOx, port trucks emit 61 tons per day.

The regulation is expected to reduce diesel particulate matter emissions from drayage trucks from baseline 2007 levels some 86 percent (2.6 tons per day) by 2010. Emissions of NOx are expected to be reduced from 2007 baseline levels by 62 percent (42 tons per day) by 2014.

ARB estimates that the proposed regulation will prevent 1,200 premature deaths from 2009 through 2020, with benefits being the most dramatic in the communities where port trucks are heavily concentrated.

Phase one of the new regulation requires all pre-1994 drayage truck engines be retired or replaced with 1994 and newer engines by the end of 2009. In addition, trucks with 1994-2003 engines will need to be either replaced or retrofitted to achieve an 85 percent reduction in diesel particulate matter by the same deadline. The second phase of the regulation requires all drayage trucks to meet 2007 emissions standards by the end of 2013.

The rule also requires compliant trucks working at the 14 ports and 11 rail yards affected by this regulation to be entered into a special registry by late 2009.

Next year, the Board will consider a similar measure which will focus on reducing emissions from in-use private heavy duty diesel truck fleets.

California Adopts Landmark Rule to Reduce Toxic Emissions from Off-Road Equipment

This news just in from the California Air Resources Board:

SACRAMENTO - The California Air Resources Board today adopted a pioneering regulation aimed at reducing toxic and cancer-causing diesel emissions from the state's estimated 180,000 "off-road" vehicles used in construction, mining, airport ground support and other industries.

"This regulation will prevent thousands of premature deaths and reduce health care costs for those suffering from respiratory disease such as asthma," said Mary Nichols, ARB Chairman. "It is also the first of its kind in the nation, and, as has occurred with other California regulations, could serve as a model for other states to follow."

Diesel particulate matter, or diesel "soot," was identified as a toxic air contaminant in 1998. In 2000, the ARB established California's Diesel Risk Reduction Plan, which aims to reduce diesel emissions to 85 percent below 2000 levels by 2020. Other sources of diesel particulate matter such as transit buses, trash trucks, cargo-handling equipment and ship auxiliary engines have already been addressed through regulations, along with diesel fuel.

Because many diesel engines lack emission controls and can remain in use for 30 years or longer, they will remain a major contributor to air pollution for years to come. The regulation adopted today will dramatically reduce emissions by installation of diesel soot filters and encouraging the replacement of older, dirtier engines with newer emission controlled models. By 2020, diesel particulate matter will be reduced by 74 percent and smog forming oxides of nitrogen by 32 percent, compared to what emissions would be without the regulation.

The new rule also includes a provision allowing areas that are currently unable to achieve clean air standards set by the US EPA for particulate matter to opt in to stricter regional requirements if incentive funds are made available. The air districts that could take advantage of this provision are the South Coast Air Quality Management District and the San Joaquin Valley Air Pollution Control District; both are considered "non-attainment areas" for particulate matter. Depending on the amount of incentive money made available, these provisions could as much as double the NOx emissions benefits in these districts, setting them on a faster track to meeting their clean air goals.

The requirements and deadlines vary depending on fleet size. For small fleets, which include small businesses or municipalities with a combined horsepower of 2500 or less, implementation does not begin until 2015. Medium fleets, with 2501 to 5000 horsepower, have until 2013, while large fleets, with over 5000 horsepower, must begin complying in 2010. Affected vehicles include bulldozers, loaders, backhoes and forklifts, as well as many other self-propelled off-road diesel vehicles.

ARB performed a comprehensive economic analysis of the rule's impact on business, concluding that the regulation will cost industry up to $3.5 billion over its lifetime. Staff reviewed individual companies' financial records and conducted numerous workshops to discuss the cost of the regulation as well as impacts on individual businesses. ARB also gave special consideration to small businesses (e.g., small fleets have until 2015 to begin compliance, while large fleets must begin in 2010) to ensure that the regulation would not provide undue economic hardship.

The Board's action today also sets the stage for efforts next year to develop similar requirements for the hundreds of thousands of on-road trucks that travel on California's roads every day.

According to ARB estimates, over its course, this rule will prevent at least 4,000 premature deaths statewide and avoid $18 to $26 billion in premature death and health costs.

The Air Resources Board is a department of the California Environmental Protection Agency. ARB's mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.

Transported Black Carbon a Significant Player in Pacific Ocean Climate

March 14, 2007 -- Soot and other particulate pollution from Asian sources make up more than 75 percent of black carbon transported at high altitudes, according to a Scripps Institution of Oceanography, UC San Diego-led study.

More than three-quarters of the particulate pollution known as black carbon transported at high altitudes over the West Coast during spring is from Asian sources, according to a research team led by Professor V. Ramanathan at Scripps Institution of Oceanography, UC San Diego.

Though the transported black carbon, most of which is soot, is an extremely small component of air pollution at land surface levels, the phenomenon has a significant heating effect on the atmosphere at altitudes above two kilometers (6,562 feet).

As the soot heats the atmosphere, however, it also dims the surface of the ocean by absorbing solar radiation, said Ramanathan, a climate scientist at Scripps, and Odelle Hadley, a graduate student at the Center for Atmospheric Sciences at Scripps. The two are lead authors of a research paper appearing in the March 14 issue of the Journal of Geophysical Research.

The dual effect carries consequences for the Pacific Ocean region that drives much of Earth’s climate.

"That’s the primary concern we have with these aerosols," said Hadley. "They can really affect global climate."

"The soot heating of the atmosphere exceeds the surface dimming and as a result the long range transported soot amplifies the global warming due to increase in carbon dioxide," said Ramanathan. "We have to find out if this amplification is just restricted to spring time or is happening throughout the year."

The researchers found that transported black carbon from Asian sources is equal to 77 percent of North American black carbon emissions in the troposphere during the spring. In a follow-on study funded by the California Energy Commission (CEC), Hadley, Ramanathan and fellow Scripps climate scientist Craig Corrigan are now studying how much carbon might be incorporated into precipitation and what the effects on melt rates of Sierra Nevada snow pack could be.

The measure of high black carbon concentration from Asian sources "is a startling finding by itself, but its potential importance is magnified by the fact that black carbon is believed to have a disproportional impact on regional climate," said Guido Franco, technical lead for climate change research at the CEC’s Public Interest Energy Research (PIER) program. "Fortunately, we have already started to address this issue with Scripps and more studies are being planned."

The researchers compared rarely available in-flight data collected during the spring 2004 Cloud Indirect Effects Experiment (CIFEX), a component of which was a series of atmospheric meteorological measurements made during flights originating in Eureka, Calif. The team combined that information with data from 30 West Coast meteorological stations and compared it with computer predictions made by the Chemical Weather Forecast System (CFORS).

Transport of Asian black carbon, particulate pollution generated by automobile exhaust, agricultural burning and other sources, is heaviest in spring when cold Arctic fronts dip to lower latitudes and loft warmer air to higher levels in the atmosphere. It is part of a worldwide transport of aerosols that sees them remain aloft at high altitudes for up to two weeks.

Black carbon concentrations diminish as they move farther away from their sources in cities and farmlands in countries such as China and India. However, over the Pacific Ocean, the particles are in sufficient concentration to have a heating effect on the upper atmosphere, a prediction based on output from other computer models besides CFORS. At the same time, the radiation-absorbing particles dim skies at the surface.

On a regional level, that amount of heating, or positive radiative forcing, the black carbon causes in the skies over the Pacific is about 40 percent of the forcing that has been attributed to the carbon dioxide increase of the last century, said Ramanathan. It likely has measurable effects on a variety of other physical and biological conditions in the areas of the Pacific over which the particulate pollution passes.

"It was a major surprise," said Ramanathan, Hadley’s adviser at Scripps. "When we came up with the preliminary results, we had to check it and recheck it."

Results from Hadley’s study of black carbon’s snow pack effects are expected by the end of this year.

Authors of the Journal of Geophysical Research article besides Hadley and Ramanathan include Corrigan, Greg Roberts and Guillaume Mauger at Scripps Oceanography and Gregory Carmichael and Youhua Tang of the University of Iowa.

The National Science Foundation, the National Oceanic and Atmospheric Administration (NOAA) and the California Energy Commission funded the study.

Pollution from China and India Affecting World’s Weather

Severe pollution from the Far East is almost certainly affecting the weather near you, says a Texas A&M University researcher who has studied the problem and has published a landmark paper on the topic in the Proceedings of the National Academy of Sciences.

Renyi Zhang, professor of atmospheric sciences at Texas A&M and lead author of the paper, says the study is the first of its kind that provides indisputable evidence that man-made pollution is adversely affecting the storm track over the Pacific Ocean, a major weather event in the northern hemisphere during winter. The project was funded by the National Science Foundation and NASA.

Zhang says the culprit is easy to detect: pollution from industrial and power plants in China and India. Both countries have seen huge increases in their economies, which mean more large factories and power plants to sustain such growth. All of these emit immense quantities of pollution – much of it soot and sulfate aerosols – into the atmosphere, which is carried by the prevailing winds over the Pacific Ocean and eventually worldwide.

Using satellite imagery and computer models, Zhang says that in roughly the last 20 years or so, the amount of deep convective clouds in this area increased from 20 to 50 percent, suggesting an intensified storm track in the Pacific.

This pollution directly affects our weather,” he explains.

During the past few decades, there has been a dramatic increase in atmospheric aerosols – mostly sulfate and soot from coal burning – especially in China and India,” he explains.

“We compared these deep convective clouds from the 10-year period of 1984-1994 to the period from 1994-2005 and discovered these storms have risen anywhere from 20 to as high as 50 percent.”

“It is a direct link from large-scale storm systems to anthropogenic (human-made) pollution.”

Zhang says the problem is especially worse during the winter months.

Because of various climate conditions, the northern Pacific Ocean is more susceptible to the aerosol effect in winter. Aerosols can affect the droplets in clouds and can actually change the dynamics of the clouds themselves, Zhang adds.

The Pacific storm track carries these polluted particles to the west coasts of Canada and the United States, across America and eventually, most of the world, Zhang notes.

“The Pacific storm track can impact weather all over the globe,” he says.

“The general air flow is from west to east, but there is also some serious concern that the Polar Regions could be affected by this pollution. That could have potentially catastrophic results.”

Soot, in the form of black carbon, can collect on ice packs and attract more heat from the sun, meaning a potential acceleration of melting of the polar ice caps, he believes.

“It possibly means the polar ice caps could melt quicker than we had believed, which of course, results in rising sea level rates,” he adds.

The pollution from the storm tracks could also signify wild weather changes, he believes.

“You might have more storms, and these storms might be more severe than usual,” he says.

“Or it could lead to the opposite – severe droughts in other areas. The Pacific storm track plays a crucial role in our weather, and there is no doubt at all that human activity is changing the world’s weather.”

Carnegie Mellon Researchers Urge Regulators to Rethink Strategies for Soot Emission

Pittsburgh -- March 1, 2007 -- Carnegie Mellon University researchers say government officials need to adopt new ways of measuring and regulating the fine particles of smoke and soot so endemic to serious health problems and the global warming crisis.

In a March 2 article published in the journal Science, professors Allen L. Robinson and Neil M. Donahue report a new conceptual model for how microscopic particles behave in the atmosphere that raises new questions about current regulations.

The research found new chemical processes that occur after soot and gaseous pollutants are emitted from cars and trucks, changing the chemical and physical properties of the soot particles and creating new particulate matter. These new particles are potentially more toxic and may have a stronger influence on cloud formation that can alter the global climate.

"One of our key findings is that this chemical processing leads to more particulate matter in the air, meaning that regulators are likely underestimating how sources such as cars and trucks contribute to pollution," said Robinson, an associate professor of mechanical engineering and engineering and public policy. "We need to take a holistic approach to regulating these sources that account for all emissions." Accounting for these new processes improves the predictions of the models federal and state governments use to develop regulations.

"A second important finding is that the properties of this new particulate matter are different than we previously thought and potentially more toxic," added Donahue, an associate professor of chemical engineering and chemistry.

Particulate matter poses a serious health problem. Fifty thousand Americans are thought to die prematurely each year due to particle exposure, and almost 70 million Americans live in areas that violate the federal standard. That standard was strengthened in September after scientists, armed with years of studies showing that these particles can damage lungs and the heart, advised the Environmental Protection Agency (EPA) that the previous standard of 65 micrograms per cubic meter of air was too loose.

A third key implication has to do with how the chemical process leads to a spreading of pollution over a larger geographic region. "We’re seeing that urban pollution doesn’t stay contained in the cities, but impacts rural and other downwind areas, creating even more complicated issues for regulators," Robinson said.

Fine particles such as smoke or dust form droplets in clouds and affect how much sun is able to pass through the cloud to earth, as well as the amount of moisture that is returned to earth. Both clouds and sunlight play key roles in climate change. The effects of particulate matter were identified as key to uncertainty in a recent report by the Intergovernmental Panel on Climate Change (IPPC) summarizing the state scientific knowledge on the impacts of human activities on global climate.

"For the longest time, particulate matter has been the least understood component of the climate system. The more we understand particulate matter, the more we realize that complexity has been masking our ability to calculate how big a role greenhouse gases have played in inducing global warming," said Donahue. "Moreover, the new mechanism we found changes the chemical properties of particles, making them more likely to participate in cloud formation. Therefore, particulate matter may be having a stronger influence on global climate than previously thought."

Long-Term Exposure to Fine Particulate Matter Increases Risk of Heart Attack and Stroke

In a recent study by The New England Journal of Medicine findings link long-term exposure to fine particulate matter (soot) found in air pollution, to cardiovascular disease. The study targeted postmenopausal women living in 36 US metropolitan areas during the years of 1994 to 1998, with a median follow-up 6 years later. The study included 65,893 women. Air pollution levels and assessed exposure were taken using the closes monitor located near each woman’s residence. Key sources of particulates include internal combustion engines (such as diesel-powered vehicles and stationary generators) and coal-fired powered plants.

The results showed 1816 women had “one or more fatal or nonfatal cardiovascular events, as confirmed by a review of medical records, including death from coronary heart disease or cerebrovascular disease, coronary revascularization, myocardial infarction, and stroke” during the study. The study showed that in increased exposure to fine particulate pollution was associated with an increase risk of heart attack, stroke and death.

The conclusion was “long-term exposure to fine particulate air pollution is associated with the incidence of cardiovascular disease and death among postmenopausal women. Exposure differences within cities are associated with the risk of cardiovascular disease.”

All Major Manufacturers Receive Approval For Emissions-Slashing Technology

WASHINGTON, Jan. 25 /PRNewswire/ — The Diesel Technology Forum today announced that all major heavy-duty truck and engine manufacturers have met new Environmental Protection Agency standards for emissions cuts and have been certified by EPA for full production.

The new big rigs are equipped with innovative new particulate matter filters that trap emissions and result in 2007 trucks being 90 percent cleaner than the previous generation of trucks. Nitrogen oxide emissions have also been reduced significantly with new technology.

“With the government certification of heavy-duty trucks now official, we can celebrate another milestone in the clean diesel transformation,” said Forum executive director Allen Schaeffer. “The nationwide availability of ultra-low sulfur diesel fuel in October 2006 provided 97 percent cleaner diesel fuel, enabling manufacturers to engineer the cleanest diesel trucks ever. With government certifications officially recognizing the success of the new diesel engines in drastically cutting emissions, all Americans can celebrate a stunning clean air achievement. Truck and engine makers stepped up to the challenge, and now we’ve all met it.”

Manufacturers now certified by the EPA include Caterpillar, Cummins, Detroit Diesel Corp., International, Mack and Volvo, meaning each is compliant with the most stringent diesel emissions standards in the world. The EPA predicts that these new trucks — once they fully replace the existing fleet — will reduce emissions of smog-forming gases by 2.6 million tons each year, and cut soot emissions by 110,000 tons annually.

“America’s long-haul truckers can be confident in the reliability and durability of these engines,” Schaeffer added. “The technology on these trucks has been engineered through millions of miles of testing, which has shown the performance, fuel economy and durability required to not only meet but exceed customer expectations.”

Because 94 percent of goods are shipped via diesel trucks, consumers can soon expect that many products they see on store shelves will be delivered by the advanced technology trucks.

The Diesel Technology Forum is a partner in the Clean Diesel Fuel Alliance (www.clean-diesel.org), a resource on technical issues relating to the new cleaner fuel and engine technology.

The Diesel Technology Forum is a non-profit organization dedicated to raising awareness about the economic importance and environmental progress of diesel engines and equipment. Forum members represent the three parts of the modern clean diesel system: advanced engines, cleaner diesel fuel and effective emissions control systems.
