The European Union leads the world in reducing sulfur in on-road diesel fuel as industry and policymakers push for ongoing reductions, a report says.
The International Fuel Quality Center has updated its ranking of the top 100 countries based on sulfur limits and says Sweden and Germany remain first and second, a release by Hart Energy Publishing says.
Japan is third, the report says.
The IFCQ ranked the United States 41st, behind Canada at 40th.
The European Union has limited sulfur in diesel fuel to 10 parts per million since January 2009.
Sulfur compounds emitted as a result of fuel combustion have detrimental environmental and health effects, and lowering sulfur levels in diesel fuel reduces tailpipe emissions by allowing the use of advanced after-treatment systems.
"The continued reduction of global diesel sulfur solidifies the environmental importance of clean diesel fuel," Frederick L. Potter, vice president of Hart Energy Publishing said.
"Today's clean diesel fuels and engines continue to change the perception of diesel as a 'dirty fuel,' and instead continue to make progress reducing on and off-road emissions, improving efficiency and lowering greenhouse gas emissions," he said.
