This release is referred to as the "carbon footprint" measured as grams or tonnes of CO2 released into the atmophere associated with types of central heating system. The table below is based on a table published by the Parliamentary Office of Science & Technology. Reduced carbon footprints are indicated under some potential levels of energy consumption savings associated with each type of heating susyem,.
