A major environmental achievement that has led to a cleaner environment while powering the global economy is clean diesel technology.
July 07, 2016 | Diesel Technology Forum
Washington, D.C. – The major environmental, economic and efficiency goals sought in California’s proposed sustainable freight plan will be attainable only with expanded use of advanced clean diesel technology, according to the Diesel Technology Forum.
These points and others were outlined in the Forum’s final comments submitted Wednesday on the draft California Sustainable Freight Action Plan concerning the development of strategies to improve freight efficiency and the transition to zero-emission freight technologies.
“Diesel engines are the prime mover in the global goods movement system, which includes California,” Allen Schaeffer, the Executive Director of the Diesel Technology Forum, stated in his comments to the California Freight Advisory Committee. “From ocean going vessels to railroad freight locomotives to medium and heavy-duty trucks, diesel engines power the movement of freight and commerce because of their unmatched combination of efficiency, power, performance, reliability, durability. And while nothing has changed about that, everything has changed about the diesel engine’s environmental credentials.
“California has played a major role driving a transformation to the new generation of clean diesel technology, now available in all modes of goods movement, from truck engines to locomotives, work boats, freight locomotives and many vessels. Today, that technology is delivering not only the goods and services that Californian’s depend on, but it also is delivering proven and tangible clean air benefits. Emissions of nitrogen oxides (NOx) from commercial diesel trucks (light, medium and heavy-duty) have declined by about 60 percent from 2000-2015, according to CARB’s most recent data. Near zero emissions clean diesel technology is now the gold standard for moving goods. Technology developed to meet California’s most rigorous standards for commercial vehicles established nearly a decade ago, has contributed to California’s goal of improving air quality while reducing greenhouse gas emissions and petroleum use.
“The fastest way for California to achieve many of the goals outlined by Governor Edmund Brown for sustainable freight movement – cleaner air, a more efficient freight system and reduced greenhouse gas emissions – is the accelerated adoption of new technology clean diesel in commercial trucks and off-road engines and equipment.
“Moreover, when considering enhancements to the freight system infrastructure, large construction equipment that will be vital to complete infrastructure projects necessary to realize the goals of the Draft Action Plan are powered nearly exclusively by diesel.
“While the plan discusses its ambitions and potential for zero emissions technology in some niche uses in the future, today clean diesel technology is delivering - fuel savings, lowering air toxic emissions, helping to achieve clean air standards and climate change goals for all Californian’s.”
According to 2015 vehicles in operation data compiled by IHS Automotive for the Diesel Technology Forum, there are more than 900,000 Class 3-8 commercial vehicles in California; about 18 percent are the newest generation clean diesel (2010MY and newer) systems that achieve both near zero NOx and PM. Since 2010, these vehicles alone have saved or eliminated 700,000 tons of NOx and 20,700 tons of PM, according to Diesel Technology Forum analysis. They have also saved or eliminated 5.8 million barrels of crude oil and 2.5 million tons of CO2. This compares with just over 15,000 natural gas powered commercial vehicles. Nationwide, almost 26 percent of the diesel commercial vehicle fleet is powered by engines that are 2010 and newer generations, according to IHS vehicles in operation statistics
“Substantial additional greenhouse gas reduction goals are achievable under a modest increase in the share of these model year 2010 compliant commercial vehicles,” Schaeffer stated. “For example, over a million tons of C02 each year may be eliminated if the share of these newest clean diesel commercial vehicles increased to just 26 percent, the national average.”
According to the South Coast Air Quality Management District (SCAQMD), an additional 80 tons of NOx emissions each day may be eliminated in the South Coast air basin if all commercial vehicles were powered by a 2010 or newer clean diesel engine.
“A unique aspect of the diesel engine is its ability to utilize a wide range of blends of high quality biofuels, such as biodiesel and renewable diesel that further enhance the benefits and capabilities of the diesel engine in a sustainable freight future.
“The Sustainable Freight Plan includes consideration of the necessary freight infrastructure - roadways and bridge systems as well as rail and port infrastructure to achieve economic growth targets and other goals. Performing this work will rely on heavy-duty diesel powered construction equipment, of which the new generation of clean diesel technology achieves near-zero emissions. Technology deployed since 2014 to meet the near-zero ‘Tier 4’ emissions standards, results in more than a 90 percent reduction in NOx and PM emissions, depending on the horsepower range of specific equipment. Much like commercial vehicles, a diesel engine powers the majority of this equipment and will continue to do so in the future.
“Agencies are already recognizing the recent clean air and fuel savings advancements in the latest clean diesel innovations that power Tier 4 construction equipment. The California High Speed Rail Authority announced that Tier 4 compliant equipment, where available, will be required at all job sites associated with the large public works project. Tier 4 compliant equipment is expected to deliver substantial air quality benefits for communities near worksites while saving fuel costs for contractors and delivering savings to the State of California.”
