This questionnaire has been devised by Environmental activist Mayer Hillman.

How much carbon dioxide is emitted from your personal use of energy

The aim is to get your total for the year in kilogrammes (kgs).

This can then be compared with your fair share of what the earth's atmosphere can absorb without serious damage to the world climate.

Where any of the questions does not apply to you, just move on to the next question.

Mayer Hillman writes:

"If we are to share responsibility for preventing emissions contributing to highly-damaging climate change, we must reduce them to less than 1 tonne".
