Portugal Environmental zones

In Portugal, for the time being, only Lisbon has an environmental zone (Zona de Emissões Reduzidas, ZER).


  • In 2020, the two existing environmental zones in Lisbon have been merged and expanded. The new zone is called ZER ABC (Zona de Emissões Reduzidas da Avenida, Baixa, Chiado).
  • Only vehicles with a permissible maximum mass of not more than 7,500 kg that meet the Euro 4 emissions standard or higher (generally vehicles built after January 2005) are allowed to enter the zone.
  • The environmental measures apply daily between 06:30 and midnight, unless stated otherwise.
  • Old vehicles that meet Euro standard 4 or higher due to modifications (such as particulate filter, LPG) are also permitted.
  • The ZER is signposted. Signs indicate for which vehicles and at what times the rules apply or do not apply.
