real-world traffic emissions:

PROVEn TO BE greater THAN EU LIMITS

Real-world conditions are different than homologation conditions

FOR MODERN VEHICLES, the difference between their emissions and their type-approval limits is still VERY LARGE

The vehicles are homologated in controlled tests. Although a more stringent new regulation has just entered into force, real life is harder than testing scenarios and vehicles emit more than during their type-approval tests. That is why  vehicles' emissions must be measured in real traffic conditions, in a non-intrusive and massive way.

Air pollutants above certain concentrations, especially particulate matter (PM) and nitrogen oxides (NOx), are a serious risk to public health. Numerous studies have identified a direct relationship between poor air quality and the number of hospital admissions and premature deaths. These reports have quantified in billions of Euros the economic impact of air pollution in Europe.

 

Air pollution causes 400,000 premature deaths in Europe every year, according to the European Environment Agency (EEA). Bad air quality is problem #1 in Europe.

 

From all sources of pollutant emissions, road traffic has become more relevant in the cities. Its importance grows with the population density.

 

In fact, road traffic may contribute with up to 80% of total pollutants in urban areas.

 

Therefore, controlling and reducing the emissions from motor vehicles must be a priority action on this area.

 

Highly polluting vehicles are very heterogeneous: cars, trucks, vans, motorcycles... Gasoline and diesel... Old and new... You will find misaligned or manipulated vehicles in all categories. It is necessary to monitor the traffic emissions of the cities to find these vehicles.

Just A few vehicles pollute a lot!

Based on our empirical research performed over the last years, it has been observed that:

* Distribution of vehicles over the Opus RSE suggested cutpoint to the Spanish Government in 2015

  • In Europe, 10% of the vehicles contribute with around the 40% of the total on road emissions.
  • The economic impact of this 10% is huge and by acting only on them, savings of millions of euros can be achieved.
  • New vehicles do not mean lower emissions. More than a half of these high emitters are relatively new vehicles (From Euro 4 to Euro 6).
  • The difference between what the Euro Standards are demanding and the real vehicles emissions is increasing with time.

These vehicles are named as High-Emitters (HE). Our RSD makes it possible to find the HIGH-EMITTERS circulating in a city, thanks to the creation of a search and identification program, monitoring traffic emissions across the main roads and districts of a metropolitan area.
