Conclusions

• Petrol/diesel worst in urban use for health/eco
• Hiway petrol CO2 diesel NO2 neg. devel.
• Diesel limits 3x gt SI engines
• Avoid cold start emissions
• Calibration on lowest HC
• Development rates CNG/LPG gt Petrol/Diesel
• DPF only in conditioned situations
• CH4 vs N2O, CO2 and cows minor issue
• Diesel vans worst LD vehicle
• Wind is not to blame for emissions
• CNG best in health/climate/ecology
