20mph zones create safer, more attractive and more enjoyable streets. They are a straightforward and logical solution for addressing a range of local concerns including the need for safer and less polluted streets. 

Our main point is that 20mph zones will help reduce air pollution, because:

(1) Edinburgh’s air pollution problem is mainly caused by traffic fumes

(2) Vehicles do not pollute more if they are driving at 20mph than if they are driving at 30mph

(3) 20mph zones will discourage car use and encourage people to use more sustainable forms of transport, which will have a knock on benefit on air quality.

We have welcomed the proposals across the city and recommended more 20mph zones, particularly in the Granton/Trinity area.
