Global warming is linked to the amount of carbon and other greenhouse gases being emitted into the atmosphere.

As individuals, almost everything we do leads to the release of carbon into the atmosphere whether that's boiling a kettle, turning your heating up in the winter or taking a Caribbean holiday.

The amount of carbon you personally produce in a year can be determined using our carbon calculator. This measure of consumed natural resources is known as your carbon footprint.

Your carbon footprint gives an indication of your impact on the environment, which is caused by the burning of fossil fuels such as oil and gas. It is measured in tonnes of carbon dioxide emitted per year. Carbon dioxide is a greenhouse gas and as such increases global warming.

If everyone made small changes to their life style - like not leaving the television on standby - then this would make a big difference in reducing our global carbon footprint.
