A new report from Cardiff University tells us that we’d have to be blithering idiots to insist that people stop using disposable coffee cups.
The environmental cost to society of disposable coffee cups is thus £3 million a year. The benefits to the population are north of £625 million a year. The method we’ve used to get here is identical to the one used to show that we really must do something about climate change.
Which we should – just as we shouldn’t about coffee cups. Because the analysis shows that we’d give up at least £625 million of consumer utility to gain £3 million in environmental savings. Why would we want to make ourselves £622 million poorer?
