Measure Your Carbon Footprint

The size of your Carbon Footprint is the amount of greenhouse gas emissions for which you’re responsible, and depends on your lifestyle, how much you fly, and so on. You can use an online tool to calculate it, and the best one I found was:

Carbon Independent's Carbon Footprint Calculator
Carbon Independent’s Carbon Footprint Calculator

 

The size of carbon footprint for each person on the planet that is sustainable is uncertain, but may be around 1.5 tonnes.

The UK average is over 13 tonnes.
