Five Double Decker Buses Filled With Gas

According to the latest research the average UK home produces six tonnes of carbon dioxide every year. Multiply that nationally and you get a total of 83 million tonnes. Studies by the Epwin Group reveal that fitting a C rated window will save 852kg of CO² per year, per property – the equivalent of five double decker buses filled with gas – and over a 35 year period this rises to 29.8 tonnes.
