The carbon calculator (formerly known as the Act on CO2 Calculator) allows individuals and households to input data to work out their carbon footprints.
The calculator is split into three sections – home energy, appliances and personal transport – and you can use it for an individual or a whole household. It also gives you a personalised action plan, which describes the steps you can take to cut your own emissions and tells you where you can find more information on specific topics – for example, how to install insulation or what grants are available.
