§ Mr. Win GriffithsTo ask the Secretary of State for Education (1) if he will list the amount in tonnes of ozone-depleting chemicals used or purchased by his Department for the years 1989, 1990 and 1991, and estimates of usage for the next year; what is the estimated bank of ozone-depleting chemicals contained within his Department; and how many months' supply of ozone-depleting chemicals have been ordered by his Department;
(2) what is his Department's policy on purchasing ozone-depleting chemicals and goods manufactured with these substances; and in which year his Department expects to cease using, purchasing or releasing ozone-depleting substances controlled by the Montreal protocol and hydrofluorocarbons;
(3) if he will outline his Department's policy on recovery and recycling of ozone-depleting chemicals.
§ Mr. FormanDetailed information is not available but it is unlikely that any significant amounts of ozone-depleting chemicals have been used or purchased by this Department in the last three years. The Department's purchasing policy is based on the supply of goods and services which avoid the use of ozone-depleting substances wherever possible.
Less than one tonne of ozone-depleting chemicals are present mainly in the sealed air conditioning units at two of the Department's leased buildings. Chiller units are regularly maintained and monitored by PSA approved contractors to prevent any leakage to the atmosphere. Any chemicals requiring replacement will be re-cycled.
