We must admit that we haven't thought about which of Britain's most loved soap series is greenest... If you have, now you don't have to wonder any more!
Long-running soap Eastenders has beaten off its rivals to be named Britain's greenest soap in new research by London 2012 Olympics sustainability partner EDF Energy.
According to the study, the characters of the E20 post code - the same as the Olympic Park - are taking more action to reduce their on-screen carbon footprint than those in the other soap series analysed. And they say watching TV can't teach you anything!
Eastender character Shirley Carter was crowned the ultimate green soap queen, with the Mitchell family being named the greenest stars.
Apart from Eastenders, the researchers studied Emmerdale, Coronation Street and Hollyoaks. Each soap's characters were monitored for one month and judged against a set of green criteria. These included their use of public transport, how many times they used electrical appliances, remembering to switch lights off and using lower carbon forms of transport such as walking or cycling. Their positive and negative 'eco-activities' were measured and compared to reveal Britain's greenest soap family.
The top five green soap families and characters are:
1. The Mitchells/Shirley Carter - EastEnders
2. The Dingles/Zak Dingle - Emmerdale
3. The Websters/Rosie Webster - Coronation Street
4. The Mitchells/Ronnie Mitchell - EastEnders
5. The Barlows/Ken Barlow - Coronation Street
