London Taxi Emissions Abatement Register

The London taxi fleet is estimated to be responsible for 12 per cent of the oxides of nitrogen (NOX) and 24 per cent of the particulate matter (PM10) from road transport emissions in central London.

Nitrogen oxides and PM10 are significant local air pollutants in London. The Mayor of London's emissions strategy for licensed London taxis requires all vehicles to be of Euro 3 emissions standard or better by 30th June 2008.

The Public Carriage Office is implementing the strategy in two phases:

  • Phase 1 affects LTi taxis which currently meet pre-Euro and Euro 1 emissions standards being presented for annual licensing between 1st July 2006 and 30th June 2007.
  • Phase 2 affects all LTi taxis which currently meet Euro 2 emissions standards and all metrocabs which currently meet pre-Euro, Euro 1 or Euro 2 standards being presented for annual licensing between 1st July 2007 and 30th June 2008.

Benefit of the emissions strategy

Taxis retrofitted with emissions reduction equipment will reduce their NOX emissions by at least 46 per cent. Their particulate matter emissions will be reduced by at least 34 per cent.
