1 any further on it.
2 MISS STEEL: I have one question. Could you get your statement
at page 6?
3 A. Yes.
4 Q. This is going back to what we have called the numbers
game. Do you consider 23.7 tonnes of HCFCs which were
5 used in 1991 to be a significant amount?
A. In terms of the worldwide usage of the chemicals at
6 that time, no.
7 Q. You do not think that .2 per cent which is 1/500ths of
everybody's use of HCFCs in the world is a large amount?
8 A. It was .02 per cent, not .2 per cent. The answer is
no. Are we talking about 1988 or 1991? In 1988 it was
9 significant, but the whole point of those figures is that
the speed with which they were phased out which is a
10 three-year period to produce a 10-fold reduction is an
extremely rapid phase out.
11
Q. The amount they were using in 1988 you would accept was
12 significant?
A. Yes.

Re-Examined by Mr. Rampton.
14
Q. I am taking these questions in order in which they arose
15 in the course of your cross-examination, so I am afraid
they will not have any structure to them. First, taking
16 chlorine loading, the orange bundle I (my Lord, this is
for reference) tab C, which is the SORG report for 1990.
17 A. Yes.
18 Q. Page 16.
A. Yes.
19
Q. The conclusion at the bottom of the right-hand column.
20 You told us earlier that 1990 was the first time that SORG
put its finger on chlorine loading, overall chlorine
21 loading in the atmosphere as being the right measure?
A. Yes.
22
Q. Can you read to yourself paragraph 2.4 on this page and
23 the next. It does not take very long.
A. Yes.
24
Q. Does that adequately summarise the approach offered by
25 chlorine loading as opposed to ozone depletion potential?
A. Yes.
26
Q. Can I ask you another question in relation to
27 polystyrene? Do you know whether or not -- you have a
background as a chemist after all -- polystyrene releases
28 methane in a landfill site?
A. I am not sure about the details of the degradation of
29 polystyrene, so I cannot comment.
30 Q. When you told us that the use of pentane as a blowing
agent made a comparatively small contribution to the
