An energy efficiency scheme run across UK universities is expected to provide savings worth £210 million.
The Revolving Green Fund was launched in 2008 and helped implement energy-saving projects in 57 universities across the country.
The government-funded organisation Salix Finance and the Higher Education Funding Council for England (HEFCE) invested £20 million in the programme.
Another £5 million of support came from a third investor.
Salix claims the 2,600 projects have so far helped the universities save more than £50 million on energy costs.
They are also expected to reduce around 82,000 tonnes of carbon emissions every year.
