Diesel fuel in the USA will have to contain a lot less sulfur thanks to a new law that just went into effect. This cleaner diesel is being compared to the removal of lead from gasoline in terms of its potential impact on air quality.
“The agency estimates that by 2030, when most old engines will have been replaced, 20,000 premature deaths, tens of thousands of illnesses, and more than 7,000 hospital visits will be prevented every year.
Officials said cleaner diesel fuel will immediately cut soot emissions from any diesel vehicle by 10 percent. But when combined with new engines hitting the road in January, it will enable emission reductions of up to 95 percent. ”
