What more can London do?
Introduce a Low Emission Zone?
What is a Low Emission Zone?
A Low Emission Zone is a zone
from which vehicles which fail to meet a specified emission standard
(such as Euro II) are excluded
London Low Emission Zone Feasibility Study
Undertaken by consultants for:• Greater London Authority• Association of London Government• Transport for London• London Boroughs• Department for Transport• Department for Environment, Food & Rural Affairs• National Society for Clean Air• Energy Saving TrustReport completed July 2003 and available at:http://www.london-lez.org

Recommendations in relation to vehicles
• If a Low Emission Zone is established, it should start with a scheme that targets lorries, London buses and coaches, as these vehicles have disproportionately high emissions per vehicle. Targeting them produces the greatest emissions reduction at the lowest cost.
• The Low Emission Zone should later be extended in later year to include vans and taxis. However, taxis could also be included earlier through the licensing process.
• The study does not recommend that cars are included in the Low Emission Zone scheme. However, it does recommend that some action is taken, in addition to the LEZ, to remove very old cars and vans from the fleet (those built before 1993).
Emission criteria
• The study recommends that lorries and buses should meet a criterion of Euro 2 with particle traps in 2007, and the criterion should be tightened to Euro 3 with particle traps in 2010.
• A NOx reduction retrofit scheme should also be considered for 2010.
• The initial scheme could develop over time into a rolling
scheme, combining Euro standard and age-based criteria.
• If vans are to be included in the Low Emission Zone scheme, the study recommends that they should meet an age-based criterion. This should be a rolling ten-year-old age limit. A similar age-based standard is also recommended for taxis, both for licensed taxis and private hire vehicles.

Costs
• The cost to vehicle operators is likely to be significantly higher than the costs of setting up and operating a London Low Emission Zone.
• The exact costs would depend on operator behaviour in response to the zone.
• Existing Government grants could offset some of these costs, but the numbers of vehicles affected by a Low Emission Zone in London would far exceed the existing grant levels.

Reduction in emissions
Reduction in area exceeding targets(relative to baseline)
(relative to baseline)
• London should meet the target forPM10 in 2007 but the target for 2010 is more stringent
Conclusions
• Even the most severe Low Emission Zone would not, on its own, result in London meeting all the air quality targets.
• The progress towards the air quality targets also has to be
seen against a natural background of improving air quality.
• The study has found that a feasible London Low Emission Zone would have modest benefits in improving overall emission levels and absolute air quality concentrations
• However, it would make a slightly larger contribution to
reducing exceedences of the air quality targets.
A joint decision on whether to implement the zone between the Mayor and London Boroughs together with the Government
Agreeing the approach with TfL London Buses and the Public Carriage Office (responsible for bus regulation and taxi licensing)
Agreeing the format of the TRO and any associated Bill or Regulations to decriminalise offences (if applicable)
Agreeing the definition of the national certification system between DfT and its agencies
Agreeing the funding and division of responsibilities
Public consultation over the preferred scheme design, and agreement over any proposed modifications
