Biodiesel and renewable diesel fuels may not be as clean as other alternative fuel types or powertrains but their widespread adoption reduced emissions more than any other type of fuel in California in 2018.
Diesel-powered trucks appear to be in the crosshairs once again as California legislators, citing overwhelming public support, call for even tougher emissions regulations.
The introduction of new technology clean diesel truck engines and emissions control systems into Pennsylvania's trucking fleet over the last five years is now at a 35% level, yielding significant emission reductions and substantial fuel savings, according to new research commissioned by the Diesel Technology Forum.
Clean diesel truck engines and emissions control systems now make up on average 30% of all heavy-duty commercial vehicles in operation in the U.S. as a result of adoption by fleets over the past five years, according to a recent report commissioned by the Diesel Technology Forum.
Alan Schaeffer of the Diesel Technology Forum also cited data showing that in emissions-sensitive southern California, more particulates come from brake dust and tire wear than from heavy diesel trucks.
U.S. Senator Tom Carper (D-Del.) has introduced a bill to extend the Diesel Emissions Reduction Act (DERA) through 2021 to continue to provide EPA grants to reduce diesel emissions.
More than 37 percent of all diesel medium and heavy duty commercial trucks registered in the U.S. are now equipped with newer technology clean diesel engines (MY-2007 or newer with near-zero particulate emissions), according to new data compiled by IHS Automotive for the Diesel Technology Forum.
The 2014 Green Fleet Conference will feature fuel ambassadors representing a different type of alternative fuel or technology from four organizations.
Since the first clean diesel engines were introduced more than seven years ago, they now represent about one-third of all the trucks registered to operate on U.S. highways. The total population of in-service clean diesel engines now numbers about 2.8 million.
Pickups still account for the majority of diesel vehicles, but cars and other passenger vehicles are increasingly powered by the compression-ignition engines.
