Directive 2005/55/EC of the European Parliament and of the Council of 28 September 2005 on the approximation of the laws of the Member States relating to the measures to be taken against the emission of gaseous and particulate pollutants from compression-ignition engines for use in vehicles, and the emission of gaseous pollutants from positive-ignition engines fuelled with natural gas or liquefied petroleum gas for use in vehicles (Text with EEA relevance) (repealed)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Mae unrhyw newidiadau sydd wedi cael eu gwneud yn barod gan y tîm yn ymddangos yn y cynnwys a chyfeirir atynt gydag anodiadau.Ar ôl y diwrnod ymadael bydd tair fersiwn o’r ddeddfwriaeth yma i’w gwirio at ddibenion gwahanol. Y fersiwn legislation.gov.uk yw’r fersiwn sy’n weithredol yn y Deyrnas Unedig. Y Fersiwn UE sydd ar EUR-lex ar hyn o bryd yw’r fersiwn sy’n weithredol yn yr UE h.y. efallai y bydd arnoch angen y fersiwn hon os byddwch yn gweithredu busnes yn yr UE. EUR-Lex Y fersiwn yn yr archif ar y we yw’r fersiwn swyddogol o’r ddeddfwriaeth fel yr oedd ar y diwrnod ymadael cyn cael ei chyhoeddi ar legislation.gov.uk ac unrhyw newidiadau ac effeithiau a weithredwyd yn y Deyrnas Unedig wedyn.
