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

An analysis by JATO Dynamics has found that average new vehicle CO2 emissions in European increased in 2018, with the total average increasing by 2.4 g/km to 120.5 g/km in 2018—the highest average of the last four years. The analysis covered 23 markets in Europe and found a direct correlation between diesel car registrations and average CO2 emissions.

With increased negative public perception towards diesels, combined with new government regulations such as WLTP and scrutiny of the fuel type, demand for diesel fell by 18% in 2018.

The introduction of WLTP in September 2018 has been a challenge for the market, as a large number of available vehicles had not been homologated yet. The increase in CO2 is certainly worrying and bad news for governments and most carmakers. Instead of moving forwards, the industry is regressing at a time when emissions targets are getting tougher.

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 g/km in 2015 to -1.4 g/km. At the same time, the sales growth of diesel cars fell from +7% to +1%. This trend was confirmed in 2017 with the first average CO2 emission increase in years of 0.3 g/km, and an 8% drop in demand for diesel cars. Last year saw an even greater variation between demand for diesel (-18%) and an increase in CO2 emissions (+2.4 g/km).

JATO attributes the main cause of the emissions increase last year to the downturn in demand for diesel. The average emissions for diesel cars continued to be lower than their gasoline counterparts (3.2 g/km).

The positive effect of diesel cars on emissions has faded away as their demand has dropped dramatically during the last year. 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.

Although the demise of diesel has certainly had an impact on emissions, it wasn’t the sole cause. The arrival of new SUVs last year, including the launch of 16 new models, paired with an increase in demand for the car type also contributed to the overall increase of average CO2 emissions in Europe.

The emissions averages for SUVs worsened by 1.4 g/km, and the SUV segment counted for 35% of passenger car registrations last year—the only segment to post a positive change in 2018.

The SUV average was the fourth highest and was only surpassed by small segments in terms of volume: sport cars, luxury sedans and vans. In contrast, the lowest emission segments (city-cars and subcompacts) posted a decline in registrations of 1.5%.

In other words, consumers in Europe are opting for the vehicles with the highest emissions, so the industry’s growth is taking place at the expense of higher emissions. The shift in fuel type from diesel to gasoline—combined with an increase in registrations in the SUV segment—is crucial to understanding the change in CO2 emissions.

The correlation between the decline in demand for diesel cars and the increase in CO2 emissions was most evident when analyzing the data by country. Only three countries saw improvements in CO2 emissions: Norway, Netherlands and Finland.

In Norway, the growing popularity of electric and hybrid cars (57% market share) was large enough to absorb the drop posted by diesel cars (-28%). In the Netherlands, the improvement was due to an increase in demand for AFVs (+74%) which counted for 11% of the total market. However, this market is still strongly dependent on gasoline cars, which make up 76% of the market.

The worst performance was seen in the UK, which has carried out one of the most aggressive campaigns against diesel.

At a brand level, Toyota was once again the leader among the top-sellers and posted an average below 100 g/km for the first time since tracking of the average CO2 emissions began. Last year, 60% of its registrations were within the hybrid range. Toyota was also one of only five brands that posted an improvement in comparison to 2017, with emissions falling by 1.4 g/km. This is mostly due to the good commercial performance of the Toyota C-HR and its fuel type mix.

Nissan saw the most improvement thanks to the strong performance of the LEAF, which became Europe’s top-selling electric car in 2018. At the same time, its top sellers (mostly SUVs) recorded registrations drops.

Volume-weighted average CO2 emissions are calculated by multiplying the CO2 emissions rating of each car version by the volumes achieved by that version in a given timescale, totalling this product for all versions, then dividing by the total volume of all versions. The data is NEDC-correlated and not WLTP.

Backward evolution for two years in a row? We may have to go to Asia (Japan and China) to find the right solutions?

Three problems:
1: People are leaving diesel, (even though the NOx problems have been solved with the latest cars).
2: People are switching to SUVs which are larger and heavier than the hatchbacks and saloons they replaced.
3: People are buying petrol cars instead of hybrid or EVs. (Cost and range, I suppose)

The best sellers in USA and Canada are very large, very heavy pick-ups with an average economy of less than 20 mpg.

Manufacturers have been pushing those monsters because making them is much more profitable than making smaller 40 mpg cars?
