Plastic bag use by the supermarkets is on the rise again – eight billion single-use plastic bags were given away to shoppers last year. But who is responsible for weaning us off them?
We’re using 10% more single-use plastic carrier bags than we were two years ago, according to the latest figures from the Waste Resources Action Plan (Wrap). But how much of a problem is this? And is it our responsibility to fix it, or should the government and retailers be playing their part too?
UK supermarkets no longer have targets to reduce the number of bags used, but when they did, it worked. In 2008, leading supermarkets signed an agreement to supply 50% fewer single-use plastic bags by 2009. They achieved 48%.
But since the agreement ended in May 2009, plastic bag use has risen again. This shows that supermarkets can’t reduce carrier bag use without regulation. So should they go back to having targets for reduction?
M&S is the only one of the seven major supermarkets to charge for bags – with profits going to charity. This has resulted in a 78% drop in bag use at its stores. Should other supermarkets follow suit? When we asked you last year, eight in ten thought plastic bags should be free.
Is it us or them?
We can all, as consumers, decide to stop accepting single-use plastic bags and use reusable bags instead, as well as reusing or recycling any single-use bags we pick up. When we asked consumers, 92% say they do reuse single-use plastic carrier bags, either for shopping (53%) or as bin liners (74%).
The government could have a role in this too – perhaps it could implement a ban or a charge for plastic bags? Countries that force shops to impose a charge on plastic bags have seen massive drops in the numbers given away. The 5p levy on single-use carrier bags introduced in Wales in 2011 resulted in Morrisons reducing carrier bag use by more than 80%.
Since 2002, shops in the Republic of Ireland have put a levy on all plastic bags (except reusable ones) to curb litter. From April 2013, shoppers in Northern Ireland will also be charged 5p a bag. But what about England? In a recent Which? survey we found that over half of people in England support a 5p charge.
A throwaway society?
Plastic bags are a symbol of our disposable society and 80% of the people asked in our survey said they are concerned about the environmental impact of plastic bags. But actually they make up less than 1% of household waste and their environmental impact is small compared to, for example, food and packaging waste. Because of this, some argue that we should be focusing on other, more impactful, environmental issues.
Do we need to be concerned about plastic bags? And if so, is it a problem for the government and supermarkets to resolve, or a challenge that consumers need to embrace ourselves?
