The Green Herald spent a bit of time road testing online carbon calculators.
For many of the calculators, you can do a simple assessment or a more detailed check where you will need your utility or energy bills at the ready.
If you like details, you need to look at your utility bills and enter information based on a selected timeframe in the Carbon Footprint Calculator.
Or you can try a quick questionnaire where you just tick boxes set up by WWF in the UK.
German climate protection organisation atmosfair provides a clear comparison of your carbon emissions specifically for travel. Simply enter your flight destination and arrival, and you get the picture.
Carbonindependent.org – a voluntary set-up by two doctors in the UK – provides a simple, one-page set of questions. Your result is then compared with individual averages from other countries – the results will surprise you.
