Mayor of London, Boris Johnson, launched the London Green500 scheme saying that the current economic crisis was the right time to implement the campaign as a lot of money could be saved if businesses became more energy efficient. "In lean economic times, there are real financial savings to be made for businesses by becoming more energy efficient, helping them to remain competitive. This can often be done in really simple and cheap ways, and it is our job in City Hall to rally, support and publicly recognise organisations that want to do so," said Johnson.
