WWC – comments received
• 85 comments received
• From the comments we have identified
– 21 issues for which we need the opinion of
the Expert Group; and
– 17 ‘straightforward’ issues (editorial and
other) for which the Expert Group is also
invited to comment.
Some fundamental issues raised
• Transportation
• Relationship with other chapters
– some suggested merging Ch. 5 and Ch. 8
– others suggested merging Ch. 5 and Ch. 6
– also, some suggested to keep chapters separate,
but move material directly related to energy
balances to Ch. 8.
Discussion
A list of issues brought up by the respondents to
the 2nd WWC has been prepared and presented
to the Expert Group.
Members of the expert group are invited to
provide their opinions on the presented issues.
