Carbon footprint competition – results and prize winners!

Thanks again to everyone who participated. The competition revealed the following results per sector and overall:

  • Energy: average 4.9 tonnes CO2 emissions annually.
  • Vehicle travel: average 3.4 tonnes CO2 emissions annually.
  • Air travel: average 3.9 tonnes CO2 emissions annually.
  • Diet: average 0.9 tonnes CO2 emissions annually.
  • Waste: average 2.9 tonnes CO2 emissions annually.
  • Total: average 14.5 tonnes CO2 emissions annually.

To put this in context, the average Australian emits  20.5 tonnes of carbon annually. This is higher than the 19.7 tonnes emitted by the average American. By comparison, China – which emits more carbon overall than any nation – has a per capita average of about 4.5 tonnes. In India, emissions are just 1.1 tonnes per person.

Thus, on average, those who participated in the carbon footprint competition emitted significantly less carbon than the average Australian; but unfortunately 14.5 tonnes of carbon per person is still far from sustainable. Current research suggests that in the medium and long term, a world-wide average of 2 tonnes of carbon dioxide per person per year is the maximum allowable quantity for sustainable life on earth.

For an inspiring example of how we might begin to achieve this, see the 1010 campaign in the UK, which has already signed up thousands of British citizens and organisations to reduce their carbon emissions by 10% in 2010.
