§ Mr. John BrowneTo ask the Prime Minister if she will make it her policy that the time horizon of between 10 and 15 years for the 100 per cent. phase-out of methyl chloroform be used by Her Majesty's Government as a base starting point for agreement at the Montreal protocol meetings due to take place in London later this month.
§ The Prime MinisterIt is the Government's policy ultimately to phase out all ozone-depleting substances. However, it is impossible at this stage to predict whether safe substitutes for all uses of methyl chloroform will be found within the next 10 or 15 years.
