On April 22, the Multilateral Fund in the Montreal Protocol announced it would fund China in its efforts to reduce production of hydrochlorofluorocarbons (HCFCs). The Fund will provide up to $385 million to help curb 4.3 million metric tons of emissions by 2030. In the agreement, China pledged to retire surplus stocks of HCFCs that are not currently in use. HCFCs have been found to deplete the ozone and are used in refrigerants and fire-suppression systems.
