     1        ozone layer?
              A.  The people who wrote the documents, which I do not
     2        think is the same as general scientific opinion, gave it
              as their estimate that at that time it was five per cent.
     3
         Q.   That was what was generally believed at the time?
     4        A.  Yes.
 
     5   Q.   So bearing that in mind, would it be accurate to describe
              a product blown with HCFCs as ozone friendly at that time?
     6        A.  Not completely ozone friendly, no.
 
     7   MISS STEEL:  Thank you.
 
     8   MR. MORRIS:  Just going back very briefly to the name change
              from CFC-22 to HCFC-22, would anybody involved in the
     9        plastics industry or packaging industry have been aware of
              that change?
    10        A.  As I do not work in the packaging industry I am not in
              a position to comment.
    11
         Q.   OK.  I am conscious of the time.  I am trying to move
    12        fairly fast through things; I am suffering maybe a bit for
              it, but -- just going back to the figures issue on usage
    13        of HCFCs and CFCs, in your statement you refer to
              McDonald's usage in 1988 and 1991, do you remember that?
    14        A.  Yes.
 
    15   Q.   If you just go to your statement briefly?
              A.  Yes.
    16
         Q.   On the third paragraph of page 6?
    17        A.  Yes.
 
    18   Q.   The figure O.272 kilo tonnes in 1988, yes?
              A.  Yes.
    19
         Q.   Applies to the HCFC use in McDonald's packaging, yes?
    20        A.  Yes.
 
    21   Q.   Were you given figures about the CFC usage in their
              packaging at the same time?
    22        A.  The figures I had were at that time the CFC use, the
              strict CFC use in the sense of 11 and 12 were zero.
    23
         Q.   That was not the case.  We know that CFC use at least ----
    24        A.  Hold on a minute.
 
    25   Q.   1988 we are talking about.
              A.  In 1988, yes, there were some CFCs being used; by the 
    26        early 1990's the strict CFCs had been phased out. 
  
    27   Q.   Does the figure of O.272 include the CFC usage as well as
              HCFC usage?
    28        A.  Yes.
 
    29   Q.   It does?
              A.  Yes. The point of those figures was actually that even
    30        if one was a mixture of CFCs and HCFCs and the second was
              HCFCs only, the actual percentage of chemicals had
