Dundee has become the second Scottish city to introduce a low emission zone (LEZ), which bans some vehicles from its city centre. Aberdeen and Edinburgh will begin enforcing their LEZs on Saturday. Glasgow was the first Scottish city to introduce the zones a year ago. It recently announced that it had received more than £1m in penalty charges issued to 33,000 drivers of non-compliant vehicles who entered the restricted zone.

Experts say it is too early to see the improvements in air quality being reflected in data because of how much of a role the weather - particularly the wind - plays in pollution levels. But modelling from other zones - such as the world's largest LEZ in Tokyo - show significant health benefits including a drop in infant mortality. A study by the Atmospheric Pollution Research journal, in August 2022, found that nitrogen dioxide levels in London's ULEZ fell by 12% in its first year.

Stephen asks - would you welcome an LEZ in your area?
