1
Now, as far as you know, and I know you are not a
2 meteorologist, was that an accurate statement of matters
as they were perceived in those days?
3 A. Yes.
4 MR. JUSTICE BELL: What does 'realisation' mean in that last
sentence?
5 A. It means, my Lord, that the warming might not
actually occur for several decades because the estimate of
6 the effect of the heat trapped in the oceans was a big
unknown in the calculations.
7
MR. RAMPTON: In the September of that year, 1987, there was
8 signed at Montreal a protocol conventional treaty relating
to the emission of CFCs into the atmosphere, was there
9 not?
A. Yes, there was.
10
Q. Was the substance known now as HCFC- 22 previously a CFC
11 22, the subject of that convention?
A. No.
12
Q. It was not. Perhaps we can deal with it this way- do you
13 have the Modern Plastics International for November 1987-
two months after the Montreal convention?
14 A. I have a copy of part of it, yes.
15 Q. I wonder if you have pages 6 and 8. It is one of Mr.
Lipsett's documents. He had the American edition. This
16 is the international edition. It is the article headed
'McDonald's Pullout: CFC Issue Hits Home.' Can we turn
17 to page 8 of that article. There is a box at the bottom of
the left hand column. "CFC treaty signed. Delegates of
18 24 nations signed an agreement on September 16 to limit
worldwide use of chlorofluorocarbons, materials under
19 scrutiny as possible agents for ozone depletion. Meeting
in Montreal under the auspices of the United Nations
20 Environment Program, participants agreed that, beginning
in 1989, they will freeze CFC use at 1986 levels; by 1994
21 consumption will be reduced by 20 per cent and by 1999,
consumption is to be cut by 30 per cent more." That makes
22 a total cut by 1999 from 1986 levels of 50 per cent, does
it not?
23 A. Yes, it does.
24 MR. JUSTICE BELL: Perhaps one ought to read on to the end.
25 MR. RAMPTON: To take effect, the agreement must be ratified by
at least eleven countries representing two- thirds of the
26 global use of CFC." So, one is talking, by 1999,
Professor Duxbury, of 50 per cent of two- thirds of the
27 global use, is one not?
A. One is.
28
Q. "Developing nations will be permitted to increase CFC
29 consumption 10 per cent per year to help economic
development."
30 A. That is what it says, yes.
