All but three European car manufacturers met their specific emission targets in 2017, based on current European vehicle test rules. Nevertheless, average carbon dioxide (CO₂) emissions from new cars sold in the European Union in 2017 rose by 0.4g of CO₂ per km from 2016, according to final data published by the European Environment Agency (EEA). This increase brings car manufacturers further away from their 2021 targets.

The EEA report “Monitoring CO₂ emissions from new passenger cars and new vans in 2017” confirms provisional data published by the EEA in April 2018. The final data show that average CO₂ emissions of a new car sold in the EU rose by 0.4 g CO₂/km in 2017 to 118.5 g CO₂/km, from 118.1 g CO₂/km in 2016—the first year-on-year increase since monitoring began.

Although this level remains below the current target level of 130 g CO₂/km, it is well above the target of 95 g CO₂/km to be achieved by 2021.

Since 2010, when monitoring started under current EU legislation, official emissions from new cars have decreased by 15.5% (almost 22 g CO₂/km). However, between 2015 and 2016, emissions decreased by only 1.5 g CO₂/km, which was less than half of the average annual reduction needed to reach the 2021 target. The increase in 2017 confirms that car makers need to achieve further and faster improvements in manufacturing and promoting more efficient cars if the target is to be met.

Average CO₂ emissions of new light commercial vehicles (vans) dropped by 7.5 g CO₂/km from 2016. The average new van registered in 2017 emitted 156.1 g CO₂/km. This reduction brings the EU average emissions 11% below the 2017 target of 175 g CO₂/km and 6% above the 2020 target.

While all van manufacturers respected their specific emission targets in 2017, three car manufacturers (Automobili Lamborghini, Mazda Motor Corporation and Société des Automobiles Alpine), representing together 1.4% of all new car sales in 2017, exceeded their specific emission targets for 2017.

While certain other manufacturers, if considered individually, would have exceeded their specific emission target, they met their obligations as members of pools or thanks to derogations.

Other key findings of the report:

• For the first year since 2009, gasoline cars constituted the majority of new registrations in 2017 (almost 53%). The proportion of electric vehicles (plug-in hybrid and battery electric cars) increased from 1.0% in 2016 to 1.5% in 2017.

• New diesel cars, which were on average around 300 kilograms (kg) heavier than new gasoline cars, emitted on average 117.9 g CO₂/km, which is 3.7 g CO₂/km less than the average gasoline car. The average fuel efficiency of new gasoline cars has been constant in 2016 and 2017, whereas the fuel-efficiency of new diesel cars has worsened compared to 2016 (116.8 g CO₂/km).

• If similar gasoline and diesel segments are compared, new conventional gasoline cars emitted 10-40% more than new conventional diesel cars. For diesel cars, only the large‑sized segment managed to achieve a small reduction (0.5 g CO₂/km) in 2017 compared with 2016. For conventional gasoline cars, large-sized cars saw a significant reduction in CO₂ emissions of around 6 g CO₂/km, and medium/small-sized cars remained rather stable.

• Small-sized cars have been replaced by medium-sized cars.

• Amongst the largest automakers, Toyota Motor Europe had the lowest average CO₂ emissions for new passenger cars registered in 2017 (with 103 g CO₂/km). Automobiles Peugeot and Automobiles Citroen followed with (105 g CO₂/km) and (106 g CO₂/km), respectively. As in every year since vans monitoring commenced, Automobile Dacia SA was the lowest-emitting vans manufacturer (118 g CO₂/km in 2017).

• BMW AG, Renault, Daimler AG, Volkswagen together sell more than 50% of the new electric vehicles in the market.

• The demand for passenger cars has been the main contributing factor to the trend in CO₂ emissions since 2000: when demand decreases, the emissions follow. Improvements in passenger car energy efficiency contributed to the reduction in CO₂ emissions from 2009 to 2016. Compared with 2000, the reduction in total CO₂ emissions from passenger cars as a result of improvements in efficiency is around 6.7 %. The biggest changes were observed between 2009 and 2013.

  In the last few years (2014-2016), the impact of this factor has been less significant. The increase in transport biofuels was also relevant in the first period: since 2005, the use of biofuels started to increase significantly, thereby contributing to decreasing emissions of CO₂ from passenger cars. Modal shift had a minor effect on the entire period.

Post-2020 CO₂ targets for cars, vans and heavy-duty vehicles. In December 2018, EU lawmakers reached an agreement on emission targets for the average fleet emissions of new passenger cars and light-commercial vehicles for 2025 and 2030. These targets aim to reduce the average CO₂ emissions from new cars by 15% in 2025 and by 37.5% in 2030, compared with 2021 baseline levels.

For light-commercial vehicles, the targets consist of reductions by 15% in 2025 and 31% in 2030, relative to 2021. In February 2019, EU lawmakers also reached an informal agreement setting a 30% reduction target for the average fleet emissions of new trucks by 2030.

The EEA collects and regularly makes available data on new passenger vehicles registered in Europe in accordance with EU Regulation (EC) No 443/2009 and data on new light commercial vehicles registered in Europe in accordance with Regulation (EU) No 510/2011. The data reported by EU Member States includes information on CO₂ emissions and vehicle weight.

In 2019, the EEA will start collecting data on new heavy-duty vehicles in accordance with Regulation (EU) No 2018/956.
