Most households had also made some ‘no-cost’ behaviour changes, estimated to give at least 5% savings on average.

|Low energy bulbs||2.14|
Average emissions per household are approx. 6 tCO2e/year, therefore direct savings from energy audits to date assuming an average of 18% savings per household are approx. 400 x 6 x 0.18 tCO2e/year = 432 tCO2e. More importantly, the energy audits have given households the information they require to make future, much larger carbon savings once obstacles, particularly of finance, have been removed.
