Schools across the borough are to save thousands of pounds and cut energy use as part of a partnership with the Carbon Trust.
Croydon Council, alongside 42 other local authorities is participating in the Collaborative Low Carbon School Service Pilot which ran for ten months last year and included eight primary schools and two secondary schools.
The council’s sustainable development and energy team now hopes to roll it out across more of the borough’s schools from April.
Councillor Jason Perry, cabinet member for planning, transport and sustainability, said: “This programme encouraged the council and 10 of our schools to work together to reduce carbon emissions and energy costs, and it had some marvellous results.
“The schools displayed insight and imagination in finding a range of ways in which savings could be made, and, by implementing a mixture of behaviour change and energy efficiency measures, showed that positive changes can be made while having a productive effect on pupils and their education.
Rockmount Primary, Upper Norwood used a simple system of red and green labels to show staff and pupils which lights could, and which should not, be switched off saving an estimated £463 and a reduction of 3.1 tonnes of CO2.
Thomas More Catholic School, Purley borrowed almost £19,000 to buy the new energy efficient fittings which should see savings of £4,100 and 23.92 tCO2 per year.
Coun Perry said: “We’re hopeful other schools will see the achievable benefits and savings, and sign up to the scheme when the low-carbon schools service in Croydon rolls out in April.”
