New regulations in California for heavy-duty diesel trucks could force a sweeping overhaul of the state’s trucking industry and pave the way for similar changes elsewhere.

The California Air Resources Board voted Friday to require trucks after 2011 to gradually reduce emissions of soot and, eventually, nitrous oxides implicated in smog formation. Remedies range from installing diesel exhaust filters at a cost of $10,000 and higher, to buying new engines or replacing trucks altogether.

Nearly all vehicles must be upgraded by 2014, and engines older than 2010 models will have to be replaced between 2012 and 2022. The goal: Reduce soot pollution 85% by 2022.  Full article in the Wall Street Journal newspaper.
