Greenpeace pressures Coca-Cola to phase out HFC refrigeration for Olympic Games in Australia 2000-2004
After the dramatic discovery of the ozone hole in 1986, activists, particularly working with Greenpeace, campaigned for an international ban on the use of ozone-depleting chlorofluorocarbons, often used in refrigeration. In 1987 country representatives in the United Nations wrote the Montreal Protocol to the Vienna Convention for the Protection of the Ozone Layer as an international treaty calling on countries to phase out and ban chlorofluorocarbons.
