1 it out?
2 MR. JUSTICE BELL: We may come to that, but on the basis that
anything you think of yourselves seems to be a good idea,
3 at least to start with, you have included, in order to get
that, in all the cattle in the world, i.e. The whole of
4 the methane emission from cattle.
A. Yes.
5
Q. Subject to evidence which comes out later, an awful lot of
6 the cattle which are emitting that methane will never
become beef on anyone's plate - whether in a McDonald's
7 restaurant or anywhere else.
A. Yes.
8
MR. RAMPTON: Does it mean this, Professor Duxbury: If, in
9 fact, McDonald's use of beef is a smaller percentage of
the world total of cattle than it is of the world total of
10 beef production, then their responsibility for methane
emissions will be that much smaller?
11 A. Yes, because the total amount of methane liberated is
known approximately for all ruminant animals.
12
MR. JUSTICE BELL: Before we can do a more precise calculation
13 we need to know what proportion of ruminants become beef?
A. Yes.
14
MR. RAMPTON: One will be able to work out, roughly speaking --
15 Perhaps one will not.
16 MR. JUSTICE BELL: We will wait and see, but it seems to me
that unless one can do that, you can get some kind of ball
17 park figure, but that is it.
A. I do not think, my Lord, you will ever be able to get
18 more than a ball park figure because of the inaccuracies
in the statistics in a large number of countries in the
19 world.
20 MR. RAMPTON: That is the end of Professor Duxbury's evidence
in-chief.

Cross-examined by the defendants.

MISS STEEL: Can I just ask something about the statement?
25 Does the statement actually go -- is it something that is
looked at when you come to make your decision or is it
26 basically the statement does not matter any more?
27 MR. JUSTICE BELL: The latter basically. I made the suggestion
that Mr. Lipsett's statement be taken as read into his
28 evidence, if you wanted it to be, so there was nothing in
there which you overlooked. If you want that to happen in
29 the future with one of your witnesses, say so. If counsel
takes a witness through his evidence, the actual evidence
30 is what he has said in the witness box, save in so far as
it may have been dealt with in shorthand by referring to
