Curbs on the most polluting vehicles driving into Edinburgh city centre will be officially introduced from Tuesday - but nothing will change for the next two years.
The Low Emission Zone (LEZ) is being launched as part of efforts to reduce pollution rates in the capital and encourage more people to use public transport.
Critics say it doesn't go far enough and will simply drive polluting traffic into other parts of the city, while residents argue it could actually encourage people to drive further in order to skirt around the zone.
