Enviromental & Legislation constrain

• The target by 2021 has been established at 95 g CO2/km

• Cars sold on 2015 emitted, on average, 119.6 g CO2/km,

(8% below the official EU target for 2015).

• 52% of car sales in EU are Diesel cars

• Average fuel efficiency of gasoline cars (122.6 g CO2/km)

• Average fuel-efficiency of diesel cars (119.2 g CO2/km)
