CO2 Mug

People around the world have become obsessed with the size of their carbon footprint - and not before time. Show your concern the next time you make your morning cuppa and pop a teabag in the CO2 Mug. It has a heat reactive world map painted on the side, so when your boiling water starts to warm the mug the countries will change colour to reveal just how much they produce in carbon emissions on an annual basis. It's quite enlightening, and more than a little bit concerning - nothing a stiff cup of tea (or a dedicated carbon reduction policy) can't fix though. It's not too late to change the world - you just need to take it one brew at a time.
