Lots of people in York did! Staff from CYC, the University of York, York NHS and Amey, along with some local councillors spent the day encouraging people to switch off their engines whilst waiting and thanking those that had already done so.
We had a great response with many drivers switching off when asked. Keep up the good work everyone!
