The term ‘carbon footprint’ is frequently used in the media, and a definition is useful for those who want to understand how their activities impact the environment. Simply stated, one’s carbon footprint comprises of the totality of greenhouse gases emitted to support one’s daily activities over a period of time, according to Carbon Tax.net.
A person’s carbon footprint is usually expressed as a numerical figure, in terms of the tonnes of greenhouse gases emitted, including carbon dioxide.
Particular activities come with their own carbon footprints. A person’s carbon footprint in one year can be calculated by adding up the greenhouses gases released to manufacture goods consumed, transport the individual, heat one’s home, and other activities and goods.
Australian has been identified as having one of highest per capita carbon footprints on the planet. For example, only five other countries in the world (Bahrain, Bolivia, Brunei, Kuwait and Qatar) emit more greenhouse gases than Australia’s annual per capita of 28.1 tonnes.
Australia’s per capita carbon footprint is twice the OECD average and quadruple the global average. The country’s relatively high carbon footprint can be partly attributed to the amount of electricity used on average in Australia.
