The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. The top sample above shows climate change impact; the subsequent chart shows human toxicity.

TSI (gasoline) and Golf Mk VII 1.6 The main focus of the comparisons is on five environmental impact categories during production, use and recycling. ozone depletion potential (ODP). photochemical ozone creation potential. Comparative life cycle impacts of the Golf (gasoline and diesel) and the e-Golf, rounded values.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. —Saliba et al.

Study finds climate impact of long distance trip can vary by factor of 10 depending upon mode, efficiency and occupancy

Green Car Congress

compared the specific climate impact of long-distance car travel with bus, train, or air trips. They accounted for both CO 2 emissions and emissions of ozone precursors (NO x , VOC, CO) and aerosols (BC or black carbon, OC, SO 2 ) as well as cloud effects (aviation-induced cirrus clouds and contrails)—i.e., fuel consumption.
