How much CO2 that's emitted is directly related to the type of and how much fuel is burned.tomcon said:I did not get a clear answer on CO2 if anybody knows this. Lets say you have a PHEV that is now past its electric range. So, you are burning gas. Say you drive 50 miles. How does the series PHEV (gas running the generator) compare to the parallel PHEV (gas running an ICE) in terms of pollutants or CO2?
Per http://web.archive.org/web/20110427044311/http://www.epa.gov/oms/climate/420f05001.htm, burning a gallon of gasoline produces 19.4 pounds of CO2. Want to produce less? Burn less of it and/or burn something w/less carbon content.
For pollutants (e.g. https://www.epa.gov/greenvehicles/light-duty-vehicle-emissions lists NOx + NMOG, CO, PM, HCHO), that has no relationship to fuel consumption. You can have really inefficient (by fuel economy and thus CO2 output) ICEVs that do well on that and very efficient ones that do poorly.
