Greenhouse gas emissions from the international maritime transport of New Zealand's imports and exports

► Cargo-based analysis of GHG emissions from New Zealand's international maritime transport of goods. ► 7.7 Mt of CO2 estimated from international maritime transport of NZ's 2007 imports and exports. ► 73% of visiting vessels' 2007 activity attributed to the movement of goods in and out of NZ. ► The results were significantly different from NZ's GHG Inventory bunker-fuel derived emissions figure. ► Detailed approach for international transport emissions regional/national assessments described.
