When oxides of nitrogen (NOx) and volatile organic compounds (VOCs) react in the presence of sunlight, ground level ozone is formed, a primary ingredient in smog. A 2005 U.S. EPA report gives road vehicles as the second largest source of VOCs in the U.S. at 26% and 19% are from non road equipment which is mostly gasoline and diesel stations.
The average for its cars will have to be 42 mpg, and for its trucks will be 26 mpg by 2016, in coordination with new CAFE standards. [22] If the average fuel economy of a manufacturer's annual fleet of vehicle production falls below its defined standard, the manufacturer must pay a penalty, then US$5.50 per 0.1 mpg under the standard ...
A Daily Telegraph article on the study described the enjoyment of new car smell as "akin to glue-sniffing". [11] However, another study showed no toxicity from new car odors in lab grown cells. The odors did trigger an immune system reaction. [12] The most common side effects of the new car smell are headaches, sore throats, nausea, and ...
The United States Centers For Disease Control and Prevention (CDC) performed indoor air quality testing for formaldehyde in some of the units. On February 14, 2008, the CDC published a preliminary report confirming that potentially hazardous levels of formaldehyde were found in many of the travel trailers and manufactured homes provided by FEMA ...
While diesel fuel contains slightly more carbon (2.68 kg CO 2 /litre) than petrol (2.31 kg CO 2 /litre), overall, the CO 2 emissions of a diesel car tend to be lower due to higher efficiency. In use, on average, this equates to around 200 g CO 2 /km for petrol and 120 g CO 2 /km for diesel.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
17 cars emit less than 80 mg/km, i.e. do not emit more NO x on this more demanding cycle than on the NEDC cycle. 22 additional cars fall below the 110% conformity factor. In total: 57% of cars have then a good chance to be compatible with WLTC-RDE. 30 cars fall above the 110% conformity factor and have then to be improved to satisfy the WLTC ...
