This weekend nearly 200 countries, including the U.S., agreed to accelerate the elimination of chemicals that threaten the ozone layer. According to the agreement reached at the United Nations–sponsored conference in Montreal on Saturday, September 22, developed countries will phase out the production of hydrochlorofluorocarbons (HCFCs) by 2020 and developing states have until 2030. This is 10 years earlier than previously promised under the 1987 Montreal Protocol.
"It is perhaps the most important breakthrough in an international environment negotiation process for at least five or six years," said United Nations Environmental Program chief Achim Steiner.
The Montreal Protocol was initially designed as a way of stopping destruction of the ozone layer, but it turns out that it also provides a way of curbing global warming, making Saturday’s new agreement all the more important and historic.
