The main purpose of this legislative proposal is to restrict U.S. funding for two significant international environmental agreements: the Montreal Protocol, which aims to protect the ozone layer, and the United Nations Framework Convention on Climate Change, which addresses global climate change. The bill seeks to impose these restrictions until China is no longer classified as a developing country in these agreements. Key provisions of the proposal include a complete prohibition on the use of federal funds for the Montreal Protocol and the UN Framework Convention on Climate Change.
