The U.S. Department of State congratulates the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer on achieving universal ratification, an unprecedented milestone in the world of international environmental agreements. Timor-Leste becomes the 196th Party to the ozone layer treaty Wednesday, September 16, on International Ozone Day.


The United States, once one of the largest users of ozone depleting substances such as chlorofluorocarbons, has phased out use of all first-generation ozone depleting substances. The United States also helps lead the way in developing countries by providing more than $20 million annually to facilitate the elimination of ozone depleting substances worldwide. According to EPA modeling, by 2165, an estimated 6.3 million American lives – and many times more, worldwide – will have been saved from fatal skin cancer as a result of worldwide action to protect the Earth’s ozone layer.
