In four weeks’ time, International Maritime Organization (IMO) member states will begin developing a strategy, for adoption in 2018, to address CO2 emissions from international shipping.

The danger is that transport officials, attending the first of a series of critical IMO meetings, may not fully grasp the new momentum for action created by the Paris Agreement on climate change.

Whether we like it or not, international shipping is vulnerable to a perception within environment ministries that shipping has somehow "escaped" the Paris Agreement, whereas land-based sectors are now covered by the CO2 reduction commitments that governments have already made.
