Householders can now calculate their exact carbon footprint through an on-line calculator set up by Repak, writes Tim O'Brien.
The carbon calculator allows users to input details of their daily activities and offers hints on how to reduce the amount of carbon produced by what they do.
Specific details about heating methods in the household are used alongside energy consumption and the various types of insulation being used.
The calculator uses information on the type of lighting in the house - including any energy-efficient light bulbs.
It then allows householders to investigate the impact that transport has on their carbon footprint, from private and public local transport to international flights.
When a householder fills in all these details, they are instantly provided with a monthly breakdown of carbon emissions, separated into three sections - home energy usage, transport and flights.
Users are also provided with a comparative average for their particular living situation and practical hints and tips on how each household can reduce its carbon footprint.
The household calculator is the first in a suite being developed by Repak.
Early next year, the industry-funded recycling body will launch carbon calculators for schools and for businesses.
Commenting on the launch of the carbon calculator, Andrew Hetherington, chief executive of Repak, said: "This well-researched tool helps people to actually realise the extent of their carbon footprint, and in particular compare this to the average Irish household.
"One of the best aspects of the calculator is that it gives each household suggestions and tips on practical ways in which they can reduce their carbon footprint.
"Recycling is one way in which people can have a serious impact on carbon emissions and our overall environmental impact by lowering our primary resource use," Mr Hetherington added.
The carbon calculator has been endorsed by Minister for the Environment John Gormley, who announced the signing of Repak's new approval as an industry recycling body to 2011.
