The World Wide Fund for Nature has an online carbon footprint calculator, so my mum and I decided to do it together. The questionnaire asks about lifestyle, travel, food, clothes and your home.

I have to say, we were disappointed. We thought we would have a better score than 96%. But our weekly car journeys between Edinburgh and Dunkeld have an impact on the environment. So, when I am old enough at 13, I will travel by bus or train, then hopefully we will get 99%.
