ASI [1] en Istituto Superiore della Sanità [2]: air pollution here are the results

A cooperation agreement between the two organizations was signed in October 2019 in order to provide a clear and correct information on the analysis of particles, nitrogen oxides and other pollutants that may be related to emissions produced by historic vehicles, depending on use and annually kilometers traveled.


In cities, domestic heating represents 42%, industry 17% and agriculture 15% of emissions. Road transport emits 11% of PM10 in the air. That is why, according to ASI, there is a need for a global approach to the problem of air emissions instead of stigmatizing historic vehicles. The ASI also requires that measures be taken that affect all sources that contribute to air pollution. This article is a summary of the results of the study commissioned by the ASI of the Istituto Superiore di Sanità as a research program into air pollutants produced by the circulation of historic vehicles. The results were presented at the Automotoretrò international trade fair [...] in Turin.


What are the conclusions of the ISS?

The presentation of the conclusions of the study was done by Andrea Piccioli, Director General of the Istituto Superiore di Sanità, Giovanni De Virgilio, scientific researcher, and Gaetano Settimo from the Department of Exposition to Air, Earth and Lifestyle at the ISS Ministry of Environment and Health. The latter presented a concise report on air pollution, pollutants and their respective sources. "For our research - Gaetano Settimo explained - we focused on the 11% emissions from car traffic to extrapolate the figure that only refers to historical vehicles that are certified based on their use and the mileage traveled each year. We worked on a sample of five Italian cities. This allowed us to establish guiding principles for national regulation of the use of these vehicles in urban areas." The representative of the Istituto Superiore di Sanità also stressed the need to clearly distinguish the categories of vehicles: "The environmental impacts to be attributed to the vehicle fleet in circulation are determined by outdated vehicles and certainly not by certified historic vehicles, as they represent a small percentage in comparison with the outdated fleet. These historic vehicles must be protected. "


What impact do historic vehicles have?

In this context, it has also been explained how emissions from vehicle traffic also include exhaust gases produced by the combustion of various petroleum products such as gasoline, diesel, natural gas and LPG, mixtures of various hydrocarbons (containing carbon and hydrogen atoms). There are also associated abrasion emissions such as mechanical abrasion products (tires, brakes, clutch) and road surface wear. Wear is only significant for emissions of particles and certain metals. In addition, account must also be taken of evaporative emissions, such as products that are emitted even when the vehicle is stopped with the engine off, such as gasoline with a variety of HC (unburned hydrocarbons). Emissions from evaporation are only significant for volatile organic compounds." Of course, the amount of emissions from means of transport also depends on the density of the fleet in circulation: of 38 million vehicles with an age of more than 11 years, historic vehicles represent around 0.9%. Statistically, in Europe, 57% of old cars (more than 30 years) drive less than 1,000 km per year. Only 14% exceeds 5,000 km. For good mechanical efficiency, it is important to take into account the fact that these [historic] vehicles must run regularly and require real know-how that must be passed on to future generations, while we are faced with a shortage of qualified personnel at this stage . "


The last word to the chairman of the ASI

"This research - said Alberto Scuro, chairman of the ASI, will form the objective and unmistakable starting point for future reflections with the institutions responsible for legislative matters. ASI and ISS have therefore found a good way to modernize the system for regulating the circulation of historic vehicles, namely the 400,000 certified [historic] vehicles (not to be confused with the 14 million obsolete vehicles in circulation). In addition, the ASI hopes to be able to maintain and continue the dialogue with national and parliamentary authorities, which have already shown interest and respect for the historical and technological [automobile] heritage and for enthusiasts. In any case, there is a high sense of responsibility towards the environment and the public interest.

Hoe vervuilend is het rijden met een klassieke wagen nu eigenlijk? Het is niet eenvoudig om hier een eenduidig antwoord op te formuleren. De discussie omvat meerdere aspecten.


Gebruik van de klassieke wagen:


Een een-op-een vergelijking in vervuiling tussen een klassieke en moderne wagen gaat niet op gezien het gebruik ervan aanzienlijk verschild. Eigenaars van klassieke wagens gebruiken hun voertuig slechts sporadisch en dan meestal nog niet in het drukke verkeer of een verstedelijkte omgeving. Op basis van onze Green Classic Heritage enquête rijdt het gemiddelde klassieke voertuig ongeveer 1.250 km per jaar, voor reguliere personenwagens is dit gemiddeld ongeveer 15.000 km.




Graag plaatsen we de CO2-emissies van rijden met een klassieke wagen ook even in perspectief door deze objectief te vergelijken met de impact van enkele andere transportmiddelen gekoppeld aan vrijetijdsbesteding in onderstaande grafiek. Een koppel dat een business retourvlucht van Brussel naar New-York neemt stoot ongeveer evenveel uit dan het jaarlijks gemiddelde van 17 klassieke wagens. Enkel via Zaventem vertrekken 24,8 miljoen passagiers per jaar…als een gemiddeld passagier voor 2.000 Kg CO2 zorgt per vlucht dan veroorzaakt het vliegverkeer (enkel) vanuit Zaventem per dag 3 keer meer uitstoot dan alle 125.000 klassieke wagens in België per jaar!


Dit neemt niet weg dat we nog steeds de ambitie moeten koesteren om rijden met een klassieke wagen verder te vergroenen. Door het compensatie-model dat we via Greentimers voorzien een overcompensatie via aanplanting van bomen zodat elke gereden km tot een negatieve CO2 uitstoot zal leiden (per gereden 10 km zal er een jaarlijkse negatieve uitstoot worden gecompenseerd van 7,2 kg CO2)


















Anderzijds stoot een klassiek wagen ook andere schadelijke stoffen uit NOx (nitrogen oxides) dewelke mee verantwoordelijke zijn voor de verontreiniging van de lucht. Hoewel we nogmaals het beperkte gebruik van klassieke wagens willen benadrukken lijken ons volgende maatregelen toch aan te raden om ook hier de impact te minimaliseren: het vermijden van de klassieke wagen te gebruiken op drukke plaatsen of momenten, het geregeld onderhoud van een klassieke wagen of het toevoegen van additieven aan de brandstof om de uitstoot te minimaliseren.
