WE ARE increasingly reminded climate change is happening due to pollution caused mainly by carbon fuel emissions. Why is it then that some drivers insist on leaving their engine running while their passenger is in the shop or gallery or wherever for upwards of 10 minutes?

This also applies to coach drivers who will park at the side of the road (we've all seen them), engine running, pumping out diesel fumes; I observed one parked in a layby for at least 30 minutes.

This, of course, also applies to delivery drivers who sit in their van eating their lunch, reading the newspaper and saying they need to keep warm. What's wrong with putting on a jacket? During warm weather, it was to keep the air conditioning going because it was too hot!

Some drivers when approached will obligingly turn off their engine; others are just downright rude and/or ignorant.

It may only be a small gesture, but enough small gestures can make a big difference.
