ALa qualit\u00e9 de l'air \u00e0 Londres s'est consid\u00e9rablement am\u00e9lior\u00e9e depuis l'extension de la zone \u00e0 tr\u00e8s faibles \u00e9missions (ULZE) \u2013 une zone de la ville dans laquelle les v\u00e9hicules polluants doivent s'acquitter d'une redevance pour pouvoir circuler.<\/span><\/p>\n

L'ULEZ a \u00e9t\u00e9 mise en place pour la premi\u00e8re fois en 2019 sous l'\u00e9gide de l'actuel maire de Londres, Sadiq Khan, puis \u00e9tendue en 2021 et 2023 ; elle couvre d\u00e9sormais l'ensemble du Grand Londres, o\u00f9 vivent environ 9 millions de personnes. Cette zone a pour objectif de r\u00e9duire la pollution, tandis que le p\u00e9age urbain vise \u00e0 r\u00e9duire le trafic (m\u00eame s'il contribue \u00e9galement \u00e0 r\u00e9duire la pollution).<\/p>\n

Les restrictions de l'ULEZ ne sont pas si strictes que cela : la plupart des voitures \u00e0 moteur diesel et essence fabriqu\u00e9es respectivement au cours des 10 et 20 derni\u00e8res ann\u00e9es sont autoris\u00e9es, bien qu'elles \u00e9mettent encore des \u00e9missions polluantes importantes par l'\u00e9chappement. Il existe \u00e9galement des d\u00e9rogations pour les bus, les v\u00e9hicules de livraison, etc.<\/p>\n

R\u00e9sultats<\/h4>\n

N\u00e9anmoins, un rapport r\u00e9cent de la City de Londres montre \u00e0 quel point l'ULEZ a permis de r\u00e9duire la pollution \u00e0 Londres et d'am\u00e9liorer la sant\u00e9 publique. Ce rapport souligne que les oxydes d'azote et les PM2,5, deux des composants les plus dangereux des \u00e9missions des v\u00e9hicules, ont diminu\u00e9 de pr\u00e8s d'un tiers par rapport \u00e0 ce qu'auraient \u00e9t\u00e9 les niveaux sans l'ULEZ.<\/p>\n

Certaines zones, comme le centre de Londres, la zone la plus dens\u00e9ment peupl\u00e9e, ont connu des baisses encore plus marqu\u00e9es : une diminution de 54% des niveaux de NO\u2082. Dans les \u2018 quartiers d\u00e9favoris\u00e9s \u2019, qui sont g\u00e9n\u00e9ralement les plus touch\u00e9s par la pollution, on a constat\u00e9 une r\u00e9duction de 80% du nombre de personnes expos\u00e9es \u00e0 des niveaux de pollution ill\u00e9gaux. Au total, 99% des stations de mesure de la qualit\u00e9 de l\u2019air r\u00e9parties dans tout Londres ont enregistr\u00e9 une baisse de la pollution ; les nouvelles r\u00e8gles ont donc profit\u00e9 \u00e0 tout le monde.<\/p>\n

Les poumons des enfants<\/h4>\n

Une \u00e9tude publi\u00e9e cette semaine par l'universit\u00e9 Queen Mary de Londres a apport\u00e9 de nouvelles informations confirmant les effets b\u00e9n\u00e9fiques de l'ULEZ sur la sant\u00e9. Cette \u00e9tude a compar\u00e9 la fonction pulmonaire des enfants \u00e0 Londres avant et apr\u00e8s la mise en place de cette mesure.<\/p>\n

L'\u00e9tude a \u00e9galement compar\u00e9 les enfants de Londres \u00e0 ceux de Luton, une ville plus petite, mais n\u00e9anmoins importante, situ\u00e9e \u00e0 la p\u00e9riph\u00e9rie de l'agglom\u00e9ration londonienne, qui n'est pas soumise \u00e0 une zone \u00e0 faibles \u00e9missions similaire. Les poumons des enfants \u00e9tant moins d\u00e9velopp\u00e9s, ceux-ci ont tendance \u00e0 \u00eatre davantage affect\u00e9s par la pollution atmosph\u00e9rique que les adultes.<\/p>\n

Les chercheurs ont recrut\u00e9 3 414 enfants \u00e2g\u00e9s de 6 \u00e0 9 ans avant la mise en place de l'ULEZ, dont 1 664 \u00e0 Londres et 1 750 \u00e0 Luton, une ville aux caract\u00e9ristiques d\u00e9mographiques comparables mais ne disposant pas de zone de qualit\u00e9 de l'air. La fonction pulmonaire a \u00e9t\u00e9 mesur\u00e9e \u00e0 plusieurs reprises \u00e0 l'aide d'une spirom\u00e9trie.<\/p>\n

Avant la mise en place de cette zone, les enfants de Luton pr\u00e9sentaient une fonction pulmonaire nettement sup\u00e9rieure \u00e0 celle des enfants de Londres. Pourtant, quatre ans seulement apr\u00e8s la mise en place de cette zone, les enfants de Londres avaient rattrap\u00e9 leur retard par rapport \u00e0 ceux de Luton. Les deux r\u00e9gions ont enregistr\u00e9 une am\u00e9lioration de la fonction pulmonaire, mais celle-ci a \u00e9t\u00e9 plus rapide \u00e0 Londres.<\/p>\n

Autres villes et pays<\/h4>\n

D'autres villes et pays ont pris des mesures similaires, et \u00e0 chaque fois, celles-ci semblent donner de tr\u00e8s bons r\u00e9sultats : r\u00e9duction du trafic, diminution de la pollution et d\u00e9placements facilit\u00e9s. Lorsque Paris (France) a banni les voitures et am\u00e9lior\u00e9 l'accessibilit\u00e9 pi\u00e9tonne ainsi que l'offre de transports pendant les Jeux olympiques, cette transformation a re\u00e7u des \u00e9loges unanimes.<\/p>\n

Belgique<\/strong> pr\u00e9sente en effet l\u2019une des \u00e9valuations ind\u00e9pendantes les plus int\u00e9ressantes d\u2019Europe concernant les zones \u00e0 faibles \u00e9missions (LEZ). Une \u00e9tude quasi-exp\u00e9rimentale publi\u00e9e en 2025 dans la revue *Environment International*, apr\u00e8s avoir fait l\u2019objet d\u2019une \u00e9valuation par les pairs, a analys\u00e9 les donn\u00e9es de 420 007 personnes, en comparant Anvers et Bruxelles \u00e0 17 villes belges de r\u00e9f\u00e9rence, ainsi qu\u2019aux zones situ\u00e9es aux abords de ces zones \u00e0 faibles \u00e9missions.<\/p>\n

L'\u00e9tude a conclu que les concentrations de PM2,5, PM10, NO\u2082 et de carbone noir avaient diminu\u00e9 nettement plus rapidement \u00e0 Anvers et \u00e0 Bruxelles que dans les villes t\u00e9moins. Il est important de noter qu'un effet \u2018 d'entra\u00eenement \u2019 positif a \u00e9galement \u00e9t\u00e9 observ\u00e9 jusqu'\u00e0 plusieurs kilom\u00e8tres au-del\u00e0 de ces zones, sans qu'il y ait de signe indiquant un simple d\u00e9placement de la pollution vers d'autres endroits.<\/p>\n

Toutefois, la derni\u00e8re \u00e9valuation de la VMM (Vlaamse MilieuMaatschappij) est plus nuanc\u00e9e. \u00c0 Anvers, l'agence indique que la LEZ a acc\u00e9l\u00e9r\u00e9 le renouvellement du parc automobile et entra\u00een\u00e9 une r\u00e9duction suppl\u00e9mentaire des concentrations de suie. N\u00e9anmoins, la LEZ actuelle a eu un effet nettement moindre sur les NOx. La circulation routi\u00e8re repr\u00e9sentait encore 68% d'\u00e9missions de NOx en 2024.<\/p>\n

La r\u00e9glementation flamande relative aux zones \u00e0 faibles \u00e9missions (LEZ) a principalement permis d'\u00e9liminer les anciens v\u00e9hicules diesel, tr\u00e8s polluants en suie. Les v\u00e9hicules diesel plus r\u00e9cents autoris\u00e9s \u00e0 circuler dans cette zone peuvent toutefois encore \u00e9mettre des quantit\u00e9s consid\u00e9rables de NOx en conditions r\u00e9elles de conduite.<\/p>\n

Le durcissement pr\u00e9vu aurait permis de s'attaquer \u00e0 ce probl\u00e8me de mani\u00e8re plus \u00e9nergique, mais il a \u00e9t\u00e9 annul\u00e9 par le gouvernement flamand en novembre 2025. La VMM estime d\u00e9sormais qu'Anvers ne sera probablement pas en mesure de respecter la limite europ\u00e9enne de NO\u2082 fix\u00e9e pour 2030 sur l'ensemble de son territoire sans mesures suppl\u00e9mentaires.<\/p>\n

Dans le cadre de la Pays-Bas<\/strong>, il n'existe aucune \u00e9tude comparable qui analyse directement l'\u00e9volution de la sant\u00e9 avant et apr\u00e8s la mise en place d'une zone \u00e0 faibles \u00e9missions. \u00c0 l'heure actuelle, la zone r\u00e9serv\u00e9e aux voitures particuli\u00e8res \u00e0 Amsterdam n'interdit toujours que les v\u00e9hicules diesel de norme Euro 4 et ant\u00e9rieures.<\/p>\n

Les v\u00e9hicules diesel Euro 5 restent autoris\u00e9s, ce qui est bien moins contraignant que la zone ULEZ de Londres (qui exige la norme Euro 6 pour les v\u00e9hicules diesel), ce qui contribue donc \u00e0 expliquer cette diff\u00e9rence.<\/p>\n

Londres<\/h4>\n

Londres appara\u00eet d\u00e9sormais comme l\u2019un des exemples les plus probants de zone \u00e0 faibles \u00e9missions (LEZ) en Europe, non pas parce que la ville a invent\u00e9 le concept, mais parce que la combinaison de plusieurs facteurs s\u2019av\u00e8re exceptionnellement efficace : une zone g\u00e9ographique tr\u00e8s \u00e9tendue, l\u2019obligation d\u2019utiliser du diesel Euro 6, une application de la r\u00e9glementation 24 heures sur 24 et 7 jours sur 7, ainsi qu\u2019une redevance journali\u00e8re de 12,50 \u00a3, suffisamment \u00e9lev\u00e9e pour modifier les comportements.\u00a0Il n\u2019est donc pas surprenant que l\u2019ULEZ de Londres fonctionne bien, mais il est agr\u00e9able d\u2019en avoir la confirmation, surtout compte tenu de la controverse qui l\u2019entourait \u00e0 l\u2019\u00e9poque.<\/p>\n

La zone ULEZ de Londres a permis d'am\u00e9liorer de mani\u00e8re tangible la qualit\u00e9 de l'air, et il existe d\u00e9sormais des preuves de plus en plus convaincantes que ces am\u00e9liorations se traduisent par de r\u00e9els bienfaits pour la sant\u00e9, en particulier chez les enfants.<\/p>","protected":false},"excerpt":{"rendered":"
