The MEPC at its sixty-fifth session had approved the
terms of reference44 for an update GHG study, and had
agreed that (a) the updated GHG study should focus
on global inventories (as set out in paragraph 1.3 of
the terms of reference) and, resources permitting,
should also include future scenarios of emissions (as
set out in the chapeau and paragraph 1.10 of the
terms of reference); (b) its primary focus should be to
update the CO2-emission estimates for international
shipping and, subject to adequate resources, the
same substances as those estimated by the Second
IMO GHG Study 2009 should also be estimated;
(c) a steering committee should be established that
should be geographically balanced, should equitably
represent developing and developed countries and
should be of a manageable size.45
