In 2014, England will follow the example set by Wales and Scotland and introduce a carrier bag charge. If the Welsh and Scottish experiences are anything to go by, the policy will drastically reduce the number of bags in circulation, keeping unnecessary waste out of landfill and removing a little polythene from the diet of our cities’ seagulls.
Like recycling, re-using carrier bags has become something of an iconic “sustainable behaviour”. But whatever else its benefits may be, it is not, in itself, an especially good way of cutting carbon. Like all simple and painless behavioural changes, its value hangs on whether it acts as a catalyst for other, more impactful, activities or support for political changes.
The evidence from Wales is not encouraging. My colleagues at Cardiff University analysed the impact of the introduction of the carrier bag charge. Although their use reduced dramatically, rates of other low-carbon behaviours among the general public remained unaffected.
To be clear: fewer plastic bags would be a small, good thing. But as a major two-day conference at the Royal Society headquarters in London this week made clear, “every little helps” is a dangerously misleading mantra when it comes to climate change.Read the rest of the article...
