Retailer Marks & Spencer will launch an in-store advertising campaign to provide an update on its carrier bag charging campaign.
From today (August 26), windows in more than 150 stores will feature the campaign, which reveals that to date M&S and its customers have reduced carrier bag usage by 80%.
A spokeswoman said: Customers are not charged for small green bags. Those who shop at the food-to-go lunchtime counter and require small bags are not charged for them, which we have said at the beginning of our campaign.
The main vest carrier bags for those doing bigger food shops are charged 5p for their bags.
The scheme was rolled out in the UK in May 2008 and has raised half a million pounds for environmental charity, Groundwork.
M&S Plan A director Richard Gillies said: Our customers have made a major impact already by saving 100 million bags and also raising half a million pounds for Groundwork but we know that there is more that we can do. Using our window to communicate what we have achieved so far is a really powerful way to encourage even more M&S customers to change their behaviour and stop using single-use carrier bags.
