For more than two decades, the 1987 Montreal Protocol has served as a shining example of how to get things done on the environment in the international arena. By banding countries together to preserve Earth’s shield against harmful ultraviolet rays, the agreement has already eliminated many ozone-depleting substances and should see off most of the rest by 2030. And in doing so, it has done more to reduce greenhouse-gas emissions than the 1997 Kyoto Protocol, which was signed expressly for that purpose. (Editorial)

Europeans back efforts to amend the Montreal Protocol to address global warming.

In your Special Report 'Cutting out the chemicals', you discuss the possible shift of regulatory control of hydrofluorocarbons (HFCs) from the UN Framework Convention on Climate Change to the Montreal Protocol (Nature 457, 518

The Montreal Protocol with its subsequent amendments and adjustments has been providing a global regulatory framework for the phase out of ozone depleting substances. Till date, CFCs, CTC, HBFCs, methyl chloroform and halons have been already phased out completely by the developed countries and a number of other ODSs are scheduled to follow.

Environmental policymaking has been equated with the art of making the right decisions based on an insufficient understanding of the underlying problems.

Watch this animated short film, Ozzy Ozone (an ozone molecule) and Alberta the Albatross take a voyage of discovery to find out exactly who and what is attacking the ozone layer, and how children can play an important role in making a difference. The Government of Barbados Ozone Programme developed the Ozzy Ozone character for use in their national awareness campaigns. This mascot has been used with awareness materials (ranging from posters to giveaway items such as pens, pencils, rulers, erasers), and as part of the Ozone Pledge programme where local companies trading in Ozone Depleting Substances (ODS) signed on to assist in the phase out of ODS. It was adapted as part of the global UNEP campaign for Ozone Day 2000, and animated in this video that TVE International produced for UNEP.
