The Change.ie Calculator is the easy way for you to  estimate how much carbon dioxide (CO2) you emit annually. The Calculator will also highlight which areas of your lifestyle have the greatest effect on climate change and will provide you with advice on what steps you can take to reduce your carbon count.

We can all play an important role in tackling climate change. Using the Calculator to help reduce our carbon count number is an easy way to take responsibility for the greenhouse gas emissions we create every time we heat our homes, drive our cars, take a flight, charge our mobile phones or turn on our computers.

Background Information on Change.ie

The Change.ie campaign originally started in April 2007, and was run by the Department of Environment, Heritage and Local Government. The campaign involved the development of carbon calculators for individuals and businessses, and a public awareness campaign promoting their use. In November 2009, responsibility for the hosting and support of these calculators was passed to the EPA. Additional educational and awareness information about the Change campaign, carbon emissions and climate change can be found on The Library Council's website at:
