On the 18 February 2012 six of 3CR's environmental programs broadcast live from the Sustainable Living Festival in the Greenhouse, Birrarung Marr, Federation Square. Following in a long tradition of bringing radio to the community by the community, the event was broadcast live on 3CR855AM, 3CR Digital and streamed on 3cr.org.au.
