How many should I buy?

Sandbag offers four levels of membership where we cancel 1, 5, 10 or more tonnes a year on your behalf.  To work out which level of membership you want you could relate your decision to your lifestyle by using a carbon calculator to estimate how much you emit from heating your home, using appliances and travelling. We recommend you use the Government’s calculator available here. Or if you want to track things in a little more detail you can create your own Carbon Account. If you are interested in not just what you emit directly but also emissions from the things you buy and consume then you can use WWF's calculator. This give a far higher value.

As a rough guide each household in the UK emits about 4-5 tonnes per year. Emissions from transport can add an extra couple of tonnes and each long haul flight adds another tonne. Adding emissions from the things we consume roughly doubles your score.
