Measures that can be taken to cut emissions and household bills include replacing old boilers and not leaving TVs and computers on standby.
According to the EST, increased energy efficiency through measures such as insulation and improving heating systems can save homes £300 a year.
This is equivalent to an average saving of around 1.5 tonnes of carbon dioxide per household.
