The 44 pages that link to Montreal Protocol, each with the reason it gives.

• ChlorineRelated: It curbed emissions of chlorine-bearing refrigerants responsible for stratospheric ozone loss.

• OzoneRelated: The treaty addresses human-made chemicals that destroy stratospheric ozone.

• Ozone depletionRelated: It coordinated the phaseout of major chemicals responsible for human-caused ozone depletion.

• Global warming potentialRelated: Its Kigali Amendment uses GWP to schedule reductions in hydrofluorocarbons.

• Ozone layerRelated: It coordinated the global response to chemical damage of the layer.

• ChlorofluorocarbonRelated: The treaty targeted CFCs after their role in ozone depletion became clear.

• BromineRelated: The treaty controls methyl bromide because it releases ozone-depleting bromine in the atmosphere.

• RefrigerantRelated: Its phaseouts drove the replacement of CFC and HCFC refrigerants.

• Antarctic ozone holeRelated: The Antarctic ozone hole galvanized support for controlling its chemical causes.

• HydrofluorocarbonRelated: Its controls on CFCs accelerated adoption of HFC alternatives.

• Chemical industryRelated: Replacing ozone-depleting industrial chemicals reshaped production in refrigeration and other sectors.

• MontrealRelated: The treaty was signed in Montreal, connecting the city’s name to global environmental cooperation.

• Ozone depletion potentialRelated: Its control schedules use ODP-weighted consumption to measure regulated substances.

• Ozone holeRelated: The treaty coordinated the global phaseout of the chemicals responsible for ozone depletion.

• FumigationRelated: The treaty drove the phaseout of methyl bromide for many fumigation uses.

• HydrochlorofluorocarbonRelated: The treaty’s controls drove the shift from CFCs to HCFCs and later alternatives.

• Ozone-depleting substanceRelated: The treaty translated evidence about these chemicals into coordinated global phaseouts.

• Thomas Midgley Jr.Related: The treaty addressed the atmospheric damage caused by CFCs like those Midgley helped develop.

• F. Sherwood RowlandRelated: The treaty translated evidence about CFC-driven ozone depletion into coordinated global controls.

• Mario MolinaRelated: Molina’s research helped establish the scientific case for controlling chlorofluorocarbons.

• Polar stratospheric cloudRelated: The ozone threat associated with cloud-mediated chemistry strengthened the case for controlling chlorofluorocarbons.

• Ultraviolet-BRelated: Its controls on ozone-depleting chemicals support recovery of the atmospheric shield against ultraviolet-B.

• Aerosol propellantRelated: Its controls on CFCs prompted the replacement of many aerosol propellants.

• Fluorine chemistryRelated: It drove replacement of ozone-depleting halogenated compounds with alternative fluorinated chemicals.

• Carbon tetrachlorideRelated: The protocol controls CCl₄ production and consumption because it depletes stratospheric ozone.

• 1,1,1-TrichloroethaneRelated: Its amendments established the global phaseout of 1,1,1-trichloroethane.

• HaloalkaneRelated: The treaty drove the global phaseout of many ozone-depleting haloalkanes.

• ChloroethaneRelated: Its controls on ozone-depleting chemicals provide context for distinguishing chloroethane from regulated compounds.

• DichlorodifluoromethaneRelated: The treaty’s controls sharply curtailed production of CFC-12 and related chemicals.

• HalocarbonRelated: The treaty controls major ozone-depleting halocarbons, including chlorofluorocarbons.

• Organochlorine chemistryRelated: It established global controls on important chlorine-containing chemicals after evidence of ozone loss.

• Paul J. CrutzenRelated: The ozone chemistry Crutzen helped establish supplied scientific grounds for controlling these substances.

• TrichlorofluoromethaneRelated: The treaty drove the global phaseout of CFC-11 production and consumption.

• 1,1,1,2-TetrafluoroethaneRelated: The treaty's controls on ozone-depleting chemicals accelerated demand for substitutes such as R-134a.

• BromomethaneRelated: The treaty established controls that sharply restricted bromomethane production and use.

• Carbon tetrafluorideRelated: CF₄ is not an ozone-depleting substance controlled by the treaty, though its fluorinated chemistry is often discussed alongside regulated gases.

• ChlorodifluoromethaneRelated: Its amendments established controls and phaseout schedules that included HCFC-22.

• FluorocarbonRelated: The treaty drove the global phaseout of many ozone-depleting fluorocarbon refrigerants.
