28 Third IMO GHG Study 2014

domestic and fishing) 1971–2011
There are significant gaps in the IEA (2013) data for 2012, at the time of this analysis. For example, international
navigation fuel sales were available for only 29 countries, representing less than 20% of total sales in 2011
(see Table 7). IEA acknowledges that recent data are based on mini-questionnaires from OECD nations and
supply data for non-OECD nations; 2012 marine fuel statistics will be updated in future editions (IEA 2013).
The IMO Secretariat scope specifies that the Third IMO GHG Study 2014 should compute annual emissions
“as far as statistical data are available”. Given the incomplete data, this work therefore excludes year 2012
from this top-down analysis.

1.1.3 Top-down fuel consumption results
This section presents the Third IMO GHG Study 2014 top-down results for the period of 2007–2011.
Review of Second IMO GHG Study 2009 top-down estimates
The consortium reviewed the Second IMO GHG Study 2009 results, including updates based on current
versions of IEA statistics. Table 8 presents a summary of the information reported in the Second IMO GHG
Study 2009 (from appendix 1, Tables A1–17), with updated information from the IEA (2013) World Energy
Statistics.
It is important to note that top-down information reported in the Second IMO GHG Study 2009 is not
definitive. First, the estimated value for 2007 (derived from 2005 using a tonne-miles adjustment in the Second
IMO GHG Study 2009) can be compared with the IEA value reported in today’s World Energy Statistics.
The 2007 IEA value is approximately 9% greater than the estimated 2007 value in the Second IMO GHG
Study 2009. Second, IEA updated the 2005 reported value with an amended total for all marine fuels that is
approximately 5% greater than the published IEA data used in the Second IMO GHG Study 2009. Most of that
