The consumer agency is working with the charity's street team and green theatre company Arcola to produce ten-minute plays on the issue of biofuels.
Members of Arcola will perform these plays throughout the summer in a range of unusual venues, including Thames barges. It is hoped the choice of venues will generate press coverage.
Agency co-founder Nik Done said that street fundraising was an 'interruptive' form of marketing. She said the agency has 'twisted our core principle of engagement marketing to make it work for street fundraising'.
