  • 6 zones in Scotland Highland NE Scotland No problem based on 2008 data for Scottish Borders and Highland Central Scotland Scottish Borders Glasgow Urban Edinburgh Urban
  • Have been considered the most cost effective measure to reduce emissions and improve air quality – if assume retrofit Operate in 11 European Countries. First introduced in Sweden in 1996, first motorway LEZ in Austria in 2007. Apply to lorries, HDVs, vehicles with 4+ wheels, all vehicles, buses under local agreements, vans. Emission standard ranges from Euro 1 to Euro 4. In Oxford, standard is Euro 5 to come into effect 1/1/14.

  • 12. © Ricardo plc 2013 • “A Low Emission Zone is where a Low Emission Strategy is implemented across a defined geographic area” • Off-Road Zones - Greenwich Peninsula, London Olympic Park, • Greenwich Millennium Village • Commonwealth games in Glasgow • Road-Based Zones - London, Oxford, Norwich, Berlin, Bologna, • Gothenburg & other European Cities • ( Low Emission Zone (LEZ)
  • 13. © Ricardo plc 2013 • Scotland needs a joined up policy to improve air quality • Benefits public health; compliance requirements; the right policies can save money and lower carbon emissions • Working with the transport sector, this can be delivered to the benefit of all.
