20's Plenty for Bradford-on-Avon

Facts & Briefings

Fact sheets and briefing are available on a wide range of topics connected with 20mph limits on our national site at www.20splentyforus.org.uk/briefings.htm

In particular in Bradford-on-avon there is concern over whether reduced speed actually reduces emissions. Well recent research has provided good news on the subject.

*The City of London recently commissioned an air quality impact report from Imperial College. This showed no negative effects.

*Department for Transport Circular 01/2013 - On Setting Local Speed Limits - Section 6, point 83 states that driving more slowly at a steady pace will save fuel and reduce pollution:

"83. Important benefits of 20mph schemes include quality of life and community benefits, and encouragement of healthier and more sustainable transport modes such as walking and cycling (Kirkby, 2002). There may also be environmental benefits as, generally, driving more slowly at a steady pace will save fuel and reduce pollution, unless an unnecessarily low gear is used. Walking and cycling can make a very positive contribution to improving health and tackling obesity, improving accessibiblity and tackling congestion, and reducting carbon emissions and improving the local environment."

*When 30km/h (18.6mph) zones were introduced in Germany, car drivers changed gear 12% less often, braked 14% less often and required 12% less fuel.

*When 20mph was introduced in Bristol, there was a 12% increase in cyclists & pedestrians, and a subsequent reduction in car use.
