EEA: Fuel efficiency improvements of new cars in Europe slowed in 2016

Green Car Congress

The EU remains well below its target of 130 g CO 2 /km set for 2015; however, compared to 2016, annual improvements in vehicle efficiency need to increase significantly in each of the coming five years in order to achieve the second average emissions target of 95 g CO 2 /km by 2021.

JATO: European new car CO2 emissions highest average since 2014; shift from diesel to gasoline and SUVs rise

Green Car Congress

The total value of CO2 emissions was on a steady decline from 2007, but started to slowdown in 2016 as the fall reduced from -4.1 If this trend continues and the adoption of alternative fueled vehicles doesn’t accelerate, the industry will need to take more drastic measures in order to meet the short- term targets.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

One segment of the on-road fleet that is believed to drive more miles and consume more fuel than the average fleet vehicle is livery (for-hire) vehicles, such as taxis and limousines. Livery fleets have changed significantly in the past decade, with many city fleets now featuring large numbers of hybrid and alternatively fueled vehicles.
