The minimum price of a single use carrier bag will double from 5p to 10p in April.

The charge, first introduced in Scotland in October 2014,is credited with an 80% reduction in the use of plastic bags.

The rise is subject to the approval of the Scottish Parliament.

Roseanna Cunningham, Environment and Climate Change Secretary, said: “While the 5p bag charge was suitable when it was first introduced, it is important that pricing is updated to ensure that the charge continues to be a factor in making people think twice about using a single-use carrier bag.”

Barry Fisher, Chief Executive of Keep Scotland Beautiful, said: “

“Fewer single use carrier bags is great news for our environment. Since 2014 the single use carrier bag charge has significantly helped reduce the number of bags being given out by retailers - saving thousands of tonnes of single use plastic realising a significant net carbon saving and reducing the chances of these items becoming littered.

"However, there is still an opportunity to challenge individual behaviours and improve consumer awareness which the doubling of the charge will help do.

“We’ve been fortunate to develop positive partnerships with a range of well-known high street retailers, and a number of small individual store owners, who understand their responsibilities in helping to tackle Scotland’s environmental issues."
