ULSD and Lower Sulfur Fuel

Return to Cleaner
Fuel Use Index

Currently low sulfur fuel (500 ppm) is the national standard for on-road
diesel fuel. Nonroad fuel is not currently regulated for sulfur.

Ultralow sulfur diesel fuel (15 ppm) will be required for
use in on-road
vehicles
starting in 2006. Lower sulfur diesel fuel (500
ppm) will be required for nonroad
diesel engines
in 2007, followed by ultralow sulfur fuel
in 2010, and for locomotives and marine
engines
in 2012. In California, ultralow will be required
for both on-road and nonroad fuel starting in 2006.

In addition to reducing emissions from the existing diesel
fleet, these cleaner, lower sulfur fuels will enable the use
of advanced aftertreatment technologies on engines. Technologies
like particulate traps, capable of dramatic emission reductions,
will be required under new standards set to begin phasing into
the on-road sector in 2007, and into the nonroad sector in 2010.
These programs will yield enormous long-term benefits for public
health and the environment.

The full benefits of these changes will not be realized until
the engine and vehicle fleet has been fully turned over, when
PM and NOx will be reduced by 250,000 tons/year and 4 million
tons/year, respectively. The West Coast Collaborative is working
to encourage early voluntary use of lower sulfur diesel fuel
and aftertreatment technologies, and early reductions in diesel
emissions.
