This is because special vehicles are made in small batches, and each requires a different filter geometry. Diesel soot filters of varying shapes can now be produced at competitive prices. Modern diesel cars are not only quieter than their predecessors but also release considerably fewer exhaust fumes into the atmosphere. The filters for heavy-duty, construction and off-road vehicles are not yet state-of-the-art. A new diesel particulate filter technology will soon teach even these vehicles to give up smoking.

They envision a zero emission car, and a transportation system completely free of fossil fuels. Little research has been done to explore carbon capture from vehicles, but now a team of scientists outline an economically feasible strategy for processing fossil or synthetic, carbon-containing liquid fuels that allows for the capture and recycling of carbon at the point of emission.

The carbon lost by converting rainforests, peatlands, savannas, or grasslands outweighs the carbon savings from biofuels. Such conversions for corn or sugarcane (ethanol), or palms or soybeans (biodiesel) release 17 to 420 times more carbon than the annual savings from replacing fossil fuels, the researchers said. The carbon, which is stored in the original plants and soil, is released as carbon dioxide, a process that may take decades. This "carbon debt" must be paid before the biofuels produced on the land can begin to lower greenhouse gas levels and ameliorate global warming.
