Shipping emissions: background Maritime transport, or ‘shipping’, emissions contribute 2.89% of anthropogenic global greenhouse gas (GHG) production, or 1, 076 million tonnes CO2. Since 90% of world trade is transported by sea, shipping has a significant role in the future of climate action, see Behnam A, ‘The Nexus of Ocean Trade and Climate Change: A Review Essay’ (2015) 29 Ocean Yearbook 11. As such business-as-usual shipping emissions are not compatible with the goal of 'holding the increase in the global average temperature to well below 2°C above pre-industrial levels' as enshrined in art 2 of the Paris Agreement.

The international climate regime and maritime emissions The term ‘international climate regime’ is commonly understood to refer to the United National Framework Convention on Climate Change (UNFCCC) (1992), the Kyoto Protocol (1997), and the Paris Agreement (2015). Notably however, none of these instruments regulate shipping emissions. The Paris Agreement, like the UNFCCC, is silent on shipping
