Transport for London policy; the Low Emission Zone
Only certain approved Diesel Particulate filter traps
are
suitable
to avoid the TfL Low Emission Zone. We currently offer two
manufactures products to a limited range of different vehicles.
Generally these are of two types
- entire exhaust system replacement
- inclusion of Filter in existing exhaust
Neither options are really cheap, but once installed the daily savings could be astronomical. At £100 a day charge, even the infrequent visitor can justify the expense.

We can't fit a gas system straight onto a Diesel
engine and it avoid LEZ charges, in fact no body can. LPG-Diesel gas
systems will not achieve anywhere near the standard. If a petrol engine
was suitably converted, the vehicle would. see here for our Gas Conversion pages.
Cars, motorcycles and vans weighing under 1.205 tonnes unladen are not affected by the LEZ. Owners can check their V5 to confirm their vehicle weight and TfL can provide advice via its website or a dedicated call centre.
In London, road transport is the single biggest source of PM10 and NOx emissions causing air quality-related health problems, worsening symptoms of asthma and other respiratory conditions. Larger vans are responsible for 21 per cent of PM emissions and 10 per cent of emissions of NOx. The LEZ aims to reduce emissions of PM and NOx by encouraging the take-up of cleaner vehicles and the fitting of approved abatement equipment, AAG offer Gas vehicles, Diesel Particulate traps, as well a "Swappage" scheme
Operators with vehicles that do not meet the specified emissions standards for the LEZ have a number of options to comply with the scheme including: 1) fitting an approved filter to the vehicle to improve the emissions - a list of approved filters is published on the TfL website; 2) purchasing a new or compliant second hand vehicle; 3) reorganising a fleet so that only vehicles which meet the required emissions standards drive within the LEZ; 4) infrequent visitors may consider renting a compliant vehicle 5) paying a daily charge. TfL would much prefer operators to meet the required standards rather than pay a daily charge or risk a fine.

From 3 January 2012, the emissions standards for vehicles already affected by the LEZ from 2008 will be tightened. Lorries over 3.5 tonnes Gross Vehicle Weight, buses and coaches over five tonnes Gross Vehicle Weight with more then 8 passenger seats will be required to meet a Euro IV for PM standard to drive within the LEZ without charge. This was announced when the scheme was originally approved in 2007 and has always been due to take effect from 3 January 2012.
The Mayor's Air Quality Strategy, published in December 2010, sets out a wide range of policies to further reduce the emissions from various sectors, including road transport. For example a package of local measures to tackle air pollution at priority locations, incentivising the adoption of the cleanest vehicles and new technologies including electric and electric-hybrid cars. It identifies that with these measures, London is on track to meet PM10 legal limits by 2011 and outlines steps to tackle NOx emissions.
