A Greener Festival’s Claire O’Neill spends an evening in Brixton’s Trinity Arms with Emma Hudson to talk about making sustainability a business proposition and playing a flying Mary Poppins in the London 2012 Opening Ceremony. I knew the areas where improvements could be made, and then looked at events like The Green Gathering, the Green Futures Field at Glastonbury, and all of these communities that had been doing this for a long time, and made a list of criteria, which then became the A Greener Festival website. I had illegal amounts of fun at parties in the woods, and we totally sorted the place out – we wouldn’t dream of just leaving it trashed, and we were having a wild time.
