The season for outdoor events and festivals is near. Yet the aftermath of most events shows overflowing waste bins and loose litter, not to mention the carbon emissions released to run the event. Some festivals are only doing the bare minimum when it comes to practicing sustainability but there are several who lead the charge in implementing green initiatives to minimize their ecological and carbon footprints. For insights we welcome: Kate Johnston, executive director of Hillside Festival, and Pam Carter, president of Mariposa Folk Festival; and avid event volunteer and Masters of Environmental Studies, Gabriella Dee.
