SAINSBURY'S stores in Huddersfield are banning disposable carrier bags to help the environment.
The company is to become the first major UK supermarket to stop giving out free disposable carrier bags in its stores.
Today all of its stores, including the branches in Market Street and Shore Head, will remove free bags from the checkouts.
Customers will instead be given free re-usable Bags for Life for their shopping.
During the day, the company will hand out an estimated seven million of the bags, which usually cost 10p.
The bags are made from 100% recycled material.
On average customers use these bags at least 20 times, which saves an estimated 90 million disposable bags each year.
The company hopes to encourage customers to keep and re-use the bags on future shopping trips.
The scheme is part of the company's Make the Difference days.
The days, to be held once a month, will encourage change across a range of environmental and ethical issues.
The Market Street store expects to give customers more than 9,000 Bags for Life today, with even more handed out at the Shore Head branch.
The bag is replaced for free when it has worn out.
Store manager Nick Hawkins said: "Our customers are showing an increasing interest in wanting to be greener or healthier, but tell us they would like more information and help on what they can do.
"They often want to do their bit, whether that's to recycle more, or cut down on carrier bags, but don't often know where to start.
"That's why Sainsbury's is launching Make the Difference days to champion specific issues to help and encourage customers and colleagues to take simple steps and actions to effect real change.
"Starting with our free Bags for Life day, this is about making change possible, easy and motivating.
"These small and easy changes today can make real and lasting differences for tomorrow."
