My Lords, I thank my noble friend the Minister for introducing this measure. I shall concentrate my remarks on the effectiveness—or otherwise—of the proposed increase in the charge for disposable carrier bags from 5p to 10p, subject to the existing legislation.
The speech made by the noble Lord, Lord Campbell-Savours, reminded me of hearing, possibly apocryphally, during my days as an undergraduate at University College, Oxford, about a thesis aired by the former and eminent professor of jurisprudence at Oxford, Professor Goodhart—a fellow at Univ, and subsequently master of our college. He put the academic case to his students at a tutorial in college that the optimal way of ensuring total compliance with road traffic law was to issue no fines or penalties but place the name of everyone who had committed an offence into a lottery, draw the tickets each year on New Year’s Eve and execute the unfortunate individual whose name was drawn first. So, he argued, the incidence of traffic violations would be solved, and began interesting tutorials challenging students to consider the principles of proportionality, deterrence and behavioural patterns.
When the levy was introduced at 5p and followed by Scotland, which I expect again to be the case on this occasion, my neighbours living in Scotland, on the Ayrshire coast, welcomed the fact that after Scotland’s original introduction of the charge in 2016, the number of carrier bags found on Scotland’s beaches fell substantially—in fact, by 40%. The Marine Conservation
Society determined that there was a further drop of 42% between 2018 and 2019. Adding a value to throwaway items results in long-term behavioural change.
The statutory instrument in front of us today challenges us to question the effect a price rise from 5p to 10p will have on behavioural patterns, if any, and whether a move to 10p, 20p, 50p or, indeed, £1, would have a significant or marginal deterrent effect. Simple changes to our daily routines need catalysts for change, and these charges are a good example. We should also keep in mind the importance of a single coin facility, so it is worth considering whether a 10p, 20p, 50p or £1 charge would meet the relevant punitive threshold and provide the tipping point to see a major change in the use of single-use carrier bags.
For my part, I believe that those who argue that moving to 50p would generate unnecessary controversy are out of touch with public sentiment—and, indeed, the views expressed by the Committee today—as the value of the deterrent is critical in considering what further shifts in consumer behaviour would result. At present, we alleviate our consciences with an associated policy of contributing to good causes. However, ultimately, an entirely successful scheme would result in no money coming in at all.
Of course, this charge applies not just to single-use plastic carrier bags but to all single-use bags; it is not simply about plastic. However, as the Minister has pointed out, this policy must be part of a panoply of measures to encourage good environmental behaviour overall, with the ultimate end of single-use carrier bags in the non-exempted category. The Marine Conservation Society and, in particular, Dr Laura Foster and her team, have done some excellent work on the campaign to add value to throwaway items, but we are a long way from the day when I can walk at low tide on a calm afternoon along Prestwick beach and not have to constantly pick up suffocating plastic washed up on the coastline, which is catastrophic to the marine environment. While I welcome this step, it is only a step, a means towards an end, not an end in itself, and I am not convinced that such a marginal change will see behavioural changes compatible with the proposed charge.
In closing, I hope that the Government will simultaneously make further progress by introducing bag deposit/return schemes, similar to those for drinks containers to encourage people to take back their drinks containers and carrier bags. I also believe a tax on on-the-go items, such as coffee cups, water bottles and plastic cutlery would encourage people to carry reusable cups and bottles, help reduce litter and increase recycling rates. I also support imposing a ban on single-use plastic when dining in restaurants and cafés. As we support this measure today, we should not lose sight of the fact that we still use well over a billion bags a year in the UK. We should be encouraging bags for life. Fortunately, there are other ways to reach the goals, which I share with my noble friend the Minister, without resorting to Professor Goodhart’s challenge.
