Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

The spatially (12 km grids) and temporally explicit LCI not only provides the level of detail necessary to perform detailed LCIA (life cycle impact assessment) of air pollutant emissions, it also gives information on spatial and temporal trends that can be useful in policy making and regulation, the authors suggest. 1 , corn ethanol: 10).

Grid cells where isoprene mixing ratio is lower than 50 pptv are not shown. Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Wennberg and colleagues also used oxygen isotopes to gain insight into the chemical mechanism yielding epoxides.
