In England we get charged for single use plastic carrier bags if the retailer has over 250 employees ... plans are in hand to increase this from 5p to `10p and for it to apply to all retailers, even small oneshttps://www.bbc.co.uk/news/uk-45353073
"A consultation will be launched later this year, the government said.
Currently, it is estimated that more than three billion bags are supplied by small and medium companies every year.
In Scotland, Wales and Northern Ireland, smaller retailers already charge a minimum of 5p for plastic bags."
So why don't they dye them a different colour, or is that another dumb question?
Bit low tech in Yorkshire then?
