CO2 emissions: the most and least polluting car brands of 2018

Smart, Citroën, Toyota, Peugeot and Seat were the five least polluting brands in the 2018 registration market. At the bottom of the ranking, Land Rover, Jaguar Porsche, Ssangyong and Volvo were positioned, according to data prepared by MSI for Ecomotor . |

The automotive market consultancy registers each and every one of the cars that each brand has sold throughout the year, accounting for the emissions of each of them measured in grams per kilometer according to their legal approval. Be careful, MSI does not limit itself to adding emissions by model, but by version, as it may be the case that the most purchased version of a certain car is the most polluting in the range of that model, or the least.

And then MSI groups the cars of each brand according to the emissions it emits. To carry out this analysis, it has been decided to count how many cars of each brand have emissions below 120 g of CO2 (Carbon Dioxide), the level that is currently used to exempt a car from paying the Registration Tax. And there is what percentage supposes the cars with emissions below 120 grams, with respect to the total registrations of each brand during the past year. Thus, the higher this percentage is, the less polluting each brand has been in the past year.

Other records have already been detecting the increase in CO2 emissions for all sales. One of the most used is the data from the Tax Agency that counts the emissions of all the cars sold, thanks to the data from the Registration Tax. The increase in gasoline already caused that in years. According to the data of the

Smart, the least polluting

Emissions by brand, based on MSI data.

To understand it better, let’s see the first and last cases in the ranking resulting from the analysis carried out by Ecomotor with MSI data. Among those with the highest sales volume, the least polluting brand according to the cars registered last year in Spain was Smart, belonging to the Mercedes-Benz group. Last year it sold 6,291 units and all of them were below 120 grams of CO2, so it achieved a 100% percentage. Which is explained by the high volume of electrics of this brand. Tesla, obviously, by only selling electric cars also obtained 100% in the pollution ranking, but it only sold 326 cars last year in Spain.

Land Rover, the most polluting

Range Rover, the most polluting brand of 2018.

At the other extreme, Land Rover, the SUV brand, ranked as the most polluting, since of the 7,802 4x4s that it sold in Spain in 2018, only 939 had approved emissions of less than 120 grams; that is, only 12%.

Well, with this dynamic of analysis and leaving out Smart, whose volume of electric vehicles partly distorts its statistics, Citroën was the least polluting general manufacturer, since 95.48% of its sales were placed below 120 g -68,468 cars out of a total of 71,706 registered-.

The third least polluting was Toyota, which thanks to the high volume of hybrid vehicles it has in its portfolio, managed to ensure that 93.48% of the 71,331 passenger cars it registered last year in Spain emit less than 120 g of CO2 per kilometer travelled. The fourth place in the pollution ranking prepared by Ecomotor, is for Peugeot, with 90.86% of its cars sold in 2018 in Spain -89,870 out of 98,909- did not exceed 120 g of CO2. Fifth place is for the Spanish brand Seat, owned by the Volkswagen group, whose “contamination percentage” was 87.16%. It must be taken into account that the brand jointly counts the cars under the new Cupra banner, much more powerful and therefore with higher emissions.

Below average: 68.41%

The average pollution of the overall sales last year was 68.41%, which means that of the 1,322,027 registered throughout 2018 in Spain, 904,427 had approved emissions below 120 grams. . Or conversely, that 417,600 passenger cars exceeded the limit that, from a fiscal point of view, is considered a non-polluting car. Of these, 266,460 had emissions certified between 121 and 140 grams of CO2 per km; 116,193 between 141,159 g; 30,716 were between 160 and 199 g and 4,771 exceeded 200 grams of CO2 emitted into the atmosphere per square kilometer.

Ten were the brands that last year placed their non-polluting emissions below the market average; that is to say, less than 68.41% of its sold cars did not reach 120 grams. Along with the first five already counted, the others that were placed in the top-ten of the least polluting were Dacia (78.55%), Skoda (76.65%), Ford (74.44%), Lexus (74 .39%) thanks, like its parent Toyota for the high volume of hybrids, and Renault closes the medal table (69.03%).

above average

The rest of the analyzed brands, another 22, had percentages lower than 66.41% of cars with less than 120 grams of total sales last year. Starting from the bottom up, that is, the most polluting, after Land Rover, Jaguar only sold 710 vehicles with emissions below the tax limit, that is, 16.15% of its registration last year. Porsche was the third brand with the highest CO2 emissions, with a percentage of 18.6%, followed by Volvo, with the exception of almost one in four cars that closes the top-5 of the most polluting.

Below the national average were also placed Mitsubishi (27.34%), Alfa Romeo (28.33%), Mazda (28.67%), Jeep (29.32%), Infiniti (36.78%) , Suzuki (45.61%), Nissan (48.8%), Honda (45.84%), BMW (47.25%), Mini (48%), Mercedes (53%), Kia (61.3 %), Audi (62.64%), Fiat (64.35%), Volkswagen (66.57%), Opel (68.17%) and Hyundai, with 68.27% of their sales last year for below 120 grams of CO2, it was very close to the national average.

Much worse than in 2017

However, despite the differences between the different mix of emissions from the ranges of each brand, the calculation in terms of emissions last year is negative when compared to 2017. The sharp increase in purchases of units powered by gasoline, which emits more Carbon Dioxide than diesel, has caused a decrease in cars that are below 120 grams. Thus, if last year 68.41% of all passenger cars sold in Spain did not exceed that limit, a year earlier it was 74.42%, 6 points more.

Thus, of the 35 brands analyzed by Ecomotor with MSI data, practically all have increased the number of cars whose emissions exceeded 120 grams; that is, more harmful to the environment. Only five have increased the percentage of units below that limit: Toyota, which has increased from 90.7% in 2017 to 93.5% last year; Seat, from 84.12% to 87.16%; Lexus, from 69.3% to 74.4%; Mitsubishi whose cars below 120 g has increased from 26.48% of its sales in 2017 to 27.34% in 2018 and Porsche, from 10% to 18.6%.

Volvo, the one that worsens the most

Among the 30 other brands that have seen their percentage of greener sales fall, the biggest declines have been recorded by Volvo, whose percentage of clean cars falls 34 points, from 59.6% to 24.9%. The second worst record is for Mini, which drops 31 points, followed by Alfa Romeo, which worsens 28.7 points, Jeep with 26 points, BMW 18.9 points, Fiat 16 percentage points, Honda 15 points, Jaguar 14.7, Kia 12.6 points, Nissan 12.1 points and Mercedes, whose percentage of cars that exceed 120 points grew 10 percentage points last year.
