Diesel Cars Produce More Toxic Emissions Than Trucks and Buses, EU Study Says (theverge.com)

Posted by msmash on from the truth-spilling dept.

Modern diesel cars produce more toxic emissions than trucks and buses, according to European researchers. That's because heavy duty vehicles in the EU have much stricter regulations than cars, and so even if they meet lab tests, cars end up producing much more nitrogen oxides (NOx) when driven on actual roads. From a report: The new report, released by the International Council on Clean Transportation (ICCT), shows that trucks and buses tested in Germany and Finland emitted about 210mg NOx per kilometer driven, less than half the 500mg/km produced by diesel cars that meet the highest "Euro 6" emission standards.

    I Know commenting on the headline is fashionable, but not even getting to the second sentence is a bit extreme even for /.

    just my own very sensitive nose can barely tell a diesel car in front vs trucks/buses I must pass(or stop) or have breathing trouble... Didn't read the referenced post but if it's true at all it must be pound for pound? Cause diesel cars dont' even come close to being as offensive.

    Nitric Oxide (NO) is colorless and odorless. Nitrogen Dioxide (NO2) has a reddish brown color and a pungent smell. So if the majority of the NOx emmissions are Nitric Oxide you couldn't smell it even if you wanted to.
