Matthew Arnold pupils get chocolate for energy saving
An Oxfordshire school has been given 365 chocolate bars for being green.
Matthew Arnold School was rewarded for saving the most amount of energy on Oxfordshire's School Switch Off day.
The student campaigning network People & Planet said giving chocolate as a prize "worked as an incentive".
The school, which has 1,089 students, was presented with the fair trade chocolate bars by the Sheriff of Oxford Penelope Glen.
A People & Planet spokesman said an average of 28% reduction in energy had happened across all the schools involved in the campaign, the equivalent of 840kg of carbon.
Seven Oxfordshire schools took part in the campaign from 21 to 25 March.
They were Bartholomew School, Langdon Village Primary School, Chiltern Edge, St Gregory the Great, Gosford Hill, Clanfield CE Primary and Matthew Arnold.
