How Canada Helped Save the Ozone Layer

While global cooperation on environmental issues may sometimes seem like a nearly impossible achievement, back in 1987 the world proved it could be done. Chlorofluorocarbons, or CFCs, had ripped open a hole in the ozone layer and it was quickly growing. Representatives from across the globe gathered in Canada to create the Montreal Protocol, a document to phase out CFCs and heal the hole. Members from the Canadian delegation, including former environment minister Tom McMillan and Green Party Leader Elizabeth May, join The Agenda to discuss lessons learned and why achieving a global environmental consensus hasn't been done since.
