Drive a fast car, use loads of gadgets, fly round the world a lot and you'll have a big carbon footprint. Walk to work, and live in a shed and you'll have a carbon footprint as dainty as hermit's sandal.

And as the world looks for ways to reduce climate change, they're under pressure to cut the carbon.
The next report from the International Panel on Climate Change is about to be delivered so The World Today commissioned intrepid explorer James Fletcher to go on a personal journey to find out how just he measures up.
In his final report, James examines how his experience compares with people in developing countries with Dr Stephan Singer, climate change campaigner for the World Wildlife Fund.
