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)
