Fig. 8From: Exhaust emission factors of greenhouse gases (GHGs) from European road vehiclesShare of CO2, N2O and CH4 emissions, considering the total GHG emissions from L-category, light-duty and heavy-duty vehicles as a baseline. The facets present the share of each GHG (CO2, N2O and CH4) in the total GHG associated to the vehicle category and standard, and the scale is shown on the left. Diesel L-category as well as dual fuel heavy-duty vehicles are excluded. As a help to the eyes, 1% is represented with a red circleBack to article page
