The Commission has a role to play in this (including in relation to measures targeting sources in the transport sector, small combustion plants and heating systems), as do the Member States (including in relation to air cleaning equipment in the agricultural sector and shipping) and decentralised authorities (in relation to mobility plans, hot spots, smog alerts).
Daarbij is een rol weggelegd voor de Commissie (o.a. op de bron gerichte maatregelen in de transportsector en voor kleine stookinstallaties en verwarmingsinstallaties), de lidstaten (o.a. luchtwasinstallaties in de landbouw en scheepvaart) en de decentrale overheden (mobiliteitsplannen, hotspots, smogalarm).
