The US Secretary of State, Hillary Clinton has emphasized the role of clean diesel technology in lowering greenhouse gas emissions in a special event organized by the Climate and Clean Air Coalition on June 3, 2012 in Stockholm, Sweden.
According to Secretary Clinton, active cooperation is essential to solve this crisis, especially from the private sector, including diesel truck manufacturers, oil and gas companies and green tech companies that can assist in converting methane to clean energy.
Diesel Technology Forum’s Executive Director, Allen Schaeffer stated that clean diesel technology advancement is garnering global interest because more number of vehicles and over 90% of worldwide trade are using diesel engines. Based on their years of research and technological advancements, the US diesel engine manufacturers are able to develop near zero emission diesel engines.
Continuous advancements in diesel technology have helped in achieving more than 98% reduction in emissions from buses and trucks. A presentation to the California Air Resource Board has revealed that advanced clean diesel technologies played a key role in reducing black carbon content in ambient air by 50% over the last 20 years.
As per the US Environmental Protection Agency report, the country will achieve significant reduction in black carbon emissions by 2030 primarily due to controls over latest mobile diesel engines. The developments in ultra-low sulfur diesel fuel and clean diesel technology have significantly reduced biological effects when exposed to diesel, according to a peer-reviewed study conducted by the Health Effects Institute.
North Carolina State University’s new research titled ‘Real-World Measurement and Evaluation of Heavy Duty Truck Duty Cycles, Fuels, and Emission Control Technologies,’ has revealed that new federal standards for tractor, trailer, and truck diesel engines have helped in reducing emissions of nitrogen oxides by 98% and particulate matter by 94%.
