Air quality management in France Focus on transports Laurence Rouïl

France continues to be concerned by PM episodes, with limit values for PM10 exceeded each year in several cities. This article discusses local action plans, air pollution episode management, and the implementation of short-term control measures, particularly in the transportation sector. It also highlights the diesel issue and the underestimation of NOx emissions from diesel cars.

  1. Air quality management in France Focus on transports Laurence Rouïl (laurence.rouil@ineris.fr)

  2. France stillconcerned by PM episodes • Limit values for PM10 exceededeachyear in several french cities France is facing infringement actions andmust reinforce control policies Number of days when the daily limit value (50 mg/m3) is exceeded(source: Bilan de la qualité de l’air 2014)

  3. Local action plans and air pollution episode management • Local action plans develop where exceedance situations are registered. All activity sectors are concerned. • A new French law (arrêtéMesuresd’Urgence, 26th march 2014) states : • Information threshold for PM10 = 50 mg/m3 • Alert threshold for PM10 = 80 mg/m3 • Short term actions to be taken by local authorities when exceedances are forecasted • Many issues with the implementation of alternate driving schemes in Paris area

  4. Short term control measures adopted in France : March 2014 • Measures adopted in various activity sectors: • Road transport : • speed limits (6 regions) • reinforcement of controls (4 regions) • city access forbidden for heavy duty vehicles (Ile de France) • Free access to public transports (13 cities) • Free residential parking • Industry: • - Voluntary reduction of activities (3 regions) • Residential heating • - recommendations for limiting wood burning (5 regions) • Agriculture: • - Warning messages to encourage limitation of fertilizers spreading (5 regions)

  5. And the diesel issue ? • In medias, PM episodes are generally associated to the specificity of the French diesel park and PM emissions from diesel cars. • But a large number of exceedancesresults from increase in ammonium nitrate concentrations • So the problem relies more on NH3 and NOx • Key issue will be the underestimationof NOx emissions from diesel cars, for both PM and NO2 exposure
