Climate change classes are to start in Shropshire - organisers believe they are the first of their kind in the UK.
The government is striving to cut CO2 by 26% by 2020
Stretton Climate Care wants to show the town's 5,000 households how they can reduce their carbon footprints.
The classes, which start on 14 January, are being run like a slimming club, with participants invited back in the future for an emissions weigh-in.
Organiser Jon Cooke said residents who cannot get to the classes will be offered a future home visit.
Chairman of Stretton Climate Care, Mr Cooke, said during the course participants will find out how high their carbon emissions are.
A computer programme will calculate how much carbon each household is responsible for and then suggest ways of reducing that weight.
Mr Cooke it would be fun with people weighing-in at the group and then comparing emissions with that of their neighbours.
"There's been lots of interest in what we're doing... I believe we're the only group in the country that is running such classes" said Mr Cooke.
