Not only has the authority beaten its target, the scheme has cut energy costs by £1 million, and £500,000 for schools, with bosses estimating the council will save £38m by 2021.
Cllr Chas Fellows, cabinet member for environment and economy, said: "We are seeing real savings from our work to reduce CO2 emissions.
"Initiatives like part-night street lighting and our four new eco-friendly community fire stations are reducing carbon emissions, but more can be done which is why we are signing up to the Local Climate commitment."
Many homeowners have already taken steps to make their own savings, improving insulation or even installing solar panels, but recent figures have revealed that fuel poverty in Britain is still very much a concern.
According to the Department for Energy and Climate Change, there are 49,154 households living in fuel poverty in Gloucestershire, representing 13.7 per cent of homes, spending more than 10 per cent of their income on heating their properties.
