With cold storage capacity at Port Newark expected to double over the next ten years, this program has the potential to significantly cut the amount of chlorodifluoromethane used in the Newark area, said EPA Regional Administrator Judith A.

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.
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.
Toxic substances of concern included asbestos (from insulation and fireproofing materials), concrete (made from Portland cement and used in the buildings' construction) and the crystalline silica it contained, CO (from fires and engine exhaust), diesel exhaust (from vehicles and equipment), mercury (from fluorescent lights), chlorodifluoromethane (Freon[TM]-22, from air conditioning systems), heavy metals (from building materials), hydrogen sulfide (from sewers, anaerobically decomposing bodies, and spoiled food), inorganic acids, volatile organic compounds (VOCs), and polynuclear aromatic hydrocarbons (PAHs) (from fires and engine exhaust).
One such alternative, chlorodifluoromethane (HCFC-22), a commercially available product, is being used alone and in blends in the extrusion of polystyrene and polyethylene foams.
Based on a draft decision presented by the Commission in November 2009 - the aim of which is to strengthen rules on allowances obtained under the Clean Development Mechanism or CDM - the EU will exclude from its Emission Trading Scheme (ETS) allowances acquired through investments in projects aimed at destroying two industrial gases, trifluoromethane (HFC-23), a by-product of production of chlorodifluoromethane (HFC-22) and nitrous oxide (N2O) emitted from the production of adipic acid HFC-23, a very harmful greenhouse gas.
On 21 January, the Climate Change Committee decided, on the basis of a proposal for a decision presented by the European Commission, on 25 November 2010, to strengthen the rules applicable to CDM appropriations following investments in projects that aim to reduce two industrial gases - trifluoromethane - HFC-230, which results from the production of chlorodifluoromethane (HFC-22) and nitrous oxide (N20), a by-product of fluoroform (HFC-23).
