Third IMO Greenhouse Gas Study 2014

Inventories of emissions of GHGs and other relevant substances 113
This section groups these tables (52–67) as follows:
• top-down fuel consumption (repeated from earlier sections);
• top-down GHG totals, including CH 4 and N 2 O;
• top-down air pollutant inventories, including SO x , NO x , PM, CO and NMVOC;
• bottom-up fuel consumption (repeated from earlier sections);
• bottom-up GHG totals, including CH 4 and N 2 O;
• bottom-up air pollutant inventories, including SO x , NO x , PM, CO and NMVOC.
