Greene King Brewing Company boss Justin Adams has teamed up with the Carbon Trust to encourage businesses to save energy.
He helped launch a drive to get companies in East Anglia to take a Carbon Survey to potentially save millions of pounds every year.
In the last couple of years, Greene King has cut its CO2 emissions by nine per cent by overhauling facilities at its Bury St Edmunds brewery.
Adams said: "It makes good sense to be smarter about the use of energy. It cut costs, improves efficiency and enhances reputation with customers - at the same as benefiting the environment."
Rising energy prices and tax increases are the biggest worries facing businesses in East Anglia in 2010, after the state of the economy, according to research released today by the Carbon Trust.
