China’s Activities and Contributions in Protecting the Ozone Layer

Global ozone depletion, like global warming, is a common problem in the atmospheric community, the concern of people all over the world and many governments. China always takes environmental protection seriously in the process of developing its economy. It makes environmental protection a fundamental policy, and promotes international cooperation as part of a sustained effort to protect the environment. China signed the Vienna Convention in September 1989, the 1990 London Amendment, and the Montreal Protocol in June 1991. Great progress has been made since the Chinese government began to carry out the State Project of Phasing Out Substances that Deplete the Ozone Layer in 1993. No fewer than 26 laws related to the subject have been approved and the use of ozone depleting substances in aerosols ceased13 years earlier than is required by the Montreal Protocol.
