Sir Richard Branson was one of the famous faces being honoured at a green awards ceremony in Los Angeles. The Virgin boss was joined on the red carpet on Sunday by Indiana Jones star Harrison Ford and his fiance Calista Flockhart. The actress picked up a prize on behalf of her television series, Brothers and Sisters. The Environmental Media Association Awards celebrates those in the media for their green credentials. Sir Richard Branson said: "When I realised how serious global warming was, we started to defer 100 percent of the profits from our dirty businesses to try to come up with clean fuels and try to come up with ways of tackling the problem."
