Tuoreen tutkimuksen mukaan Suomessa pieni joukko polttomoottoriautoja tuottaa puolet henkil\u00f6autojen haitallisista pienhiukkasp\u00e4\u00e4st\u00f6ist\u00e4 sek\u00e4 katsastuksissa ett\u00e4 moottoritieajossa. Tampereen ja It\u00e4-Suomen yliopistojen tutkijat arvioivat, ett\u00e4 ilmanlaatua voidaan parantaa tehokkaimmin romutuspalkkion kaltaisilla kohdennetuilla toimilla.<\/p>\n\n\n\n

Suomessa autokannan keski-ik\u00e4 on Euroopan korkeimpia, ja liikenteen hiukkasp\u00e4\u00e4st\u00f6ist\u00e4 suurin osa tulee yli 15 vuotta vanhoista polttomoottoriajoneuvoista. Erityisen saastuttavia ovat vanhat dieselautot ilman hiukkassuodatinta. <\/p>\n\n\n\n

Vuoden 2025 lopussa valmistunut tutkimus osoitti, ett\u00e4 Suomessa hiukkasp\u00e4\u00e4st\u00f6t jakautuvat ep\u00e4tasaisesti: pieni joukko ajoneuvoja tuottaa ison osan kokonaisp\u00e4\u00e4st\u00f6ist\u00e4. Tutkijoiden mukaan moottoritieajossa noin 10 % ja katsastusmittauksessa noin 5 % polttomoottoriautoista aiheuttaa noin puolet pienhiukkasp\u00e4\u00e4st\u00f6ist\u00e4.<\/p>\n\n\n\n

\u2013 Tutkimuksemme mukaan uudet polttomoottoriautot tuottavat moottoritiell\u00e4 keskim\u00e4\u00e4rin noin 70\u202f% v\u00e4hemm\u00e4n hiukkasia kuin romutettavaksi p\u00e4\u00e4tyv\u00e4t vanhat autot. Ilmanlaatua voidaan parantaa huomattavasti tehokkaammin kohdentamalla toimenpiteit\u00e4 eniten saastuttaviin ajoneuvoihin kuin koko autokantaa koskevilla yleistoimilla, kertoo aerosolifysiikkaan erikoistunut tutkijatohtori Ville Leinonen<\/strong> Tampereen yliopistosta.<\/p>\n\n\n\n

Leinonen odottaa, ett\u00e4 vuoden 2026 alussa voimaan tullut yli 10 vuotta vanhoja autoja koskeva romutuspalkkio<\/a> v\u00e4hent\u00e4\u00e4 osaltaan hiukkasp\u00e4\u00e4st\u00f6j\u00e4 kannustamalla uusien v\u00e4h\u00e4p\u00e4\u00e4st\u00f6isten menopelien hankkimiseen.<\/p>\n\n\n\n
