However, as required by the Clean Air Act, automobile manufacturers began installing onboard refueling vapor recovery (ORVR) technologies in 1998, making gas stations’ systems increasingly redundant. Since 2006, all new automobiles and light trucks (pickups, vans and SUVs) are equipped with ORVR systems.

systems in areas classified “Serious,” “Severe,” or “Extreme” for nonattainment of the ozone national ambient air quality standard (NAAQS). Gasoline-rich vapors in an empty automobile fuel tank are forced out when liquid gasoline is pumped into the tank. The CAA requires states to implement Stage II gasoline vapor recovery.

James Donaldson, is a mixture of thousands of chemical compounds spewed into the air by automobiles, factories and a host of other sources. When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. Among these compounds are nitrogen oxides. —James Donaldson.

In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust. lower ozone formation potential of the carbonyl compounds present than DF under the identical operating conditions.

Ranges in passenger occupancy can easily change the relative performance of modes, with large aircraft performing better than light rail in some of the areas investigated. Samples of the findings include: Off-peak urban diesel buses has the largest energy consumption and GHG emissions per PKT, followed by the three light-duty vehicles.

The California waiver authority exists because California has uniquely difficult problems with ozone-forming pollutants. The action finalizes parts of the SAFE Vehicles Rule that was first proposed on 2 August 2018. Earlier post.)

An unambiguous ranking of the specific climate impact can be established for freight transportation, with shipping and rail having lowest and light trucks and air transport having highest specific impact for all cases calculated. As planes fly at high altitudes, their impact on ozone and clouds is disproportionately high, though short lived.
