London based media and communictaions agency, Forster, beat a host of other companies, big and small with varying environmental impacts, to win the title at the awards ceremony held in London’s Covent Garden on 20 May 2009. The implementation of initiatives including additional holiday for those travelling to work on foot or by bicycle, and thinking local first for all suppliers, were just some of the policies that helped them on their way to being crowned Britain's greenest business for 2009. Media giant The National Magazine Company finished in second place overall, with construction company Willmott Dixon third.
