This one is plain and simple: either take ten minutes to enjoy your coffee in-situ, or take a reusable cup with you when you want a hot drink on-the-go. There is no shortage of stylish, practical alternatives to the paper cup.

Here are a few of our favourites:

1. Frank Green: easily cleanable and totally spill-proof. Fill it up, pop it in your bag, and run for the train - revolutionary.

2. The JOCO Cup: these glass cups are BPA and chemical-free and come in standard takeaway cup sizes, meaning they’re perfect to use in your local coffee shop.

3. The KeepCup: sustainably produced and colourful, you can pick from a range of sizes and materials or design your own.

4. Contigo Austoseal Mug: while being a little more chunky than the others, this is a rare gem as it's vacuum insulated and sealed, meaning you can make your cuppa at home and enjoy it two hours later, still steaming hot.

A word to the wise: choose your cup carefully and then use it as many times as you possibly can. Reusable cups (plastic, metal and other) all have their own carbon footprint, and unless you use again and again and again, there’s a chance you’ll be causing more harm than good.
