1. Bottling it

There’s still some way to go to break the UK’s 10m-a-day disposable bottle habit, but we’re using refillables more than ever before. Some 60 per cent of Brits now carry a reusable bottle, compared to just 20 per cent eight years ago, and for some they’ve become a fashion accessory. 

Gone is the awkwardness over asking for a top-up. In fact, like many things, there’s even an app for that. maps 330,000 venues that offer free water refills, as well as places where you can take your own lunchbox for food to go. It also highlights coffee shops that give discounts to customers who bring reusable cups.
