Welcome to the Big Green Switch Carbon Calculator.
Using the simple form below, you can estimate your average annual carbon footprint - the volume of carbon emissions that you are personally responsible for - and find out which areas you are most likely to be able to make a reduction.

The calculator takes into account the major contributing factors to your carbon footprint, including the energy and fuel you use and the impact of your consumerism and waste management.

Please try to answer as many questions as you can to get the most accurate estimate of your carbon footprint.
