Japanese trading companies know the detail of every single factory in the world producing hydrochlorofluorocarbons
, nitrous oxide etc.
The ongoing global phaseout of chlorofluorocarbons (CFCs), and subsequently hydrochlorofluorocarbons
(HCFCs), used as the refrigerant in most systems has led manufacturers to seek out new refrigerants.
When it became known that chlorofluorocarbons and hydrochlorofluorocarbons
in refrigerants were contributing to depletion of the earth's protective ozone layer, NIST began a program (funded by the Department of Energy's Office of Basic Energy Sciences and Office of Building Technologies) to measure the properties of their replacements.
Several years ago, scientists realized that gases known as hydrochlorofluorocarbons
and hydrofluorocarbons, which have replaced ozone-destroying CFCs in many products, break down in the atmosphere to form TFA.
and Cleburne, Texas -- released chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons
(HCFCs) into the atmosphere.
The European Union (EU) has proposed stronger restrictions for developing countries on the production of hydrochlorofluorocarbons
(HCFCs), one of the alternatives to ozone-depleting chlorofluorocarbons (CFCs), government sources said Tuesday.
Industry's long-term reliance on chlorofluorocarbons (CFCs), hydrochlorofluorocarbons
(HCFCs), methyl bromide, and other chemicals is resulting in a global atmospheric crisis that cannot be ignored.
The proposal to toughen rules on hydrochlorofluorocarbons
(HCFCs) tops the agenda of the five-day conference of the signatories to the 1987 Montreal Protocol on ozone layer, according to conference sources.
Per Rosenqvist of the European Commission delivered an update on European Union policy, which is proposing to advance elimination of hydrochlorofluorocarbons
(HCFCs) to 2008 instead of 2015, which later date had been well ahead of the world deadline set by the Montreal Protocol.
The packaging for hamburgers and other hot McDonald's foods contained ozone-damaging hydrochlorofluorocarbons
(HCFCs) and is "recycled" in only five of the chain's 550 restaurants in Britain.
According to rules proposed by the EPA to meet the accelerated schedule, production of chlorofluorocarbons (CFCs), carbon tetrachloride and methyl chloroform will be halted in 1996, production of halons in 1994, and production of hydrochlorofluorocarbons
(HCFCs) will be phased out by 2030.
16) launch a national strategy to gradually reduce Hydrochlorofluorocarbons
(HCFC) which cause the depletion of the ozone layer.
