The most commonly used variant in homes is known as chlorodifluoromethane
These refrigerants were identified as feasible alternatives for replacement of R-22 (chlorodifluoromethane
), a refrigerant that was popular for these applications.
Among other items, duties on Mineral waters, Calcium Carbide, Hydrogen peroxide, Razors, Safety Blades and Chlorodifluoromethane
are increased by 5-10 per cent.
In 2016, there was 89 tonnes of refrigerants in total, including R11 (trichlorofluoromethane), R12 (dichlorodifluoromethane), R13 (chlorotrifluoromethane), R22 (chlorodifluoromethane
), R114 (dichlorotetrafluoroethane), R125, R134a, R141b, cyclopentane, isopentane, propane, and butane.

An important example of such a data set is the global distribution of species like chlorodifluoromethane
, or HCFC-22, which is being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer.
(85.) See, e.g., Wara, supra note 17, at 1779-80 (explaining that adipic acid and chlorodifluoromethane
industries, which have bad environmental impacts, have earned a large number of credits).
The Montreal Protocol, the international agreement that phases out ozone-depleting substances, requires the end of chlorodifluoromethane
production by 2020 in developed countries and 2030 in developing countries.
Chemicals: Asbestos, benzene, bis(2-ethylhexyl) phthalate, bisphenol A epoxy resins, boron and its compounds, butyl benzyl phthalate, di-n-butyl phthalate, chlorodifluoromethane
, chromium and trivalent chromium, cobalt and its compounds, water-soluble copper salt (excluding complex salt), dichloromethane, dioxins, ethene, ethylbenzene, ethylene glycol, hydrazine, hydrogen fluoride and its water-soluble salts, lead and its compounds, manganese and its compounds, molybdenum and its compounds, piperazine, polyoxyethylene alkyl ethers, silver and its water-soluble compounds, tetrachloroethylene, toluene, 1,3,5-trimethylbenzene, xylene
The ban will apply to credits from projects which destroy two industrial gases: trifluoromethane (HFC-23), a by-product of chlorodifluoromethane
(HCFC-22), a refrigerant in air conditioners and refrigerators, and nitrous oxide (N2O) from adipic acid production used in the manufacture of nylon.
