EC advances HCFC phaseout.
In June, the European Community Commission proposed a regulation that would
phase out hydrochlorofluorocarbons by the year 2015, ahead of the 2030 deadline
established last November by parties to the Montreal Protocol. The regulation
would also exceed the Protocol by specifying a 25 percent reduction in the
production and use of methyl bromide by 1996. For reactions to the proposal and
impacts on industry see Intl. Environ. Rptr. (p. 428, June 16 1993), and
Global Environ. Change Rep. (p. 3, June 11 and p. 7, June 24 1993).
A panel established under the Montreal Protocol has recommended that no uses of
halons be exempt from the 1994 phaseout schedule established last November.
Requests for exemptions are to be submitted to UNEP by parties to the Protocol
by the end of September. The issue will be discussed at the next conference of
parties to the Protocol, to be held in Bangkok in November. (See Intl.
Environ. Rptr., p. 539, July 28 1993; Global Environ. Change Rep.,
p. 3, Aug. 27 1993).
substitute. Laboratory tests at Australia's Commonwealth Scientific and
Industrial Research Organization (CSIRO) show that carbonyl sulfide, a
naturally-occurring gas, would be an effective fumigant for soil and grain, but
would have no measurable effect on stratospheric ozone or climate. Methyl
bromide has not been subject to phaseout under the Montreal Protocol because it
is widely used as a fumigant and no substitute has been available. (See New
Scientist, p. 10, July 31 1993).
