This report by the Environment Agency and Saving Energy Trust seeks to determine the CO2 emissions resulting from specific water using activities and behaviours in the home. Building on a 2008 study, it calculates the CO2 quantities generated at different stages of the water supply-use-treatment process. It also estimates which household appliances produce how much CO2 emissions, considering hot and cold water use, different energy sources, and use scenarios between existing and new houses. Additionally, the study provides numbers about financial costs of CO2 savings from various measures has been quantified.
