As previously stated on, at the 66th meeting of its Marine Environment Protection Committee the IMO voted to adopt amendments to MARPOL Annex VI Tier III regulations relating to NOx emissions. The implementation for superyachts under 500GT has now been pushed back until January 2021.

It is fair to say that ICOMIA has played a pivotal role in bringing the superyacht fraternity together to lobby for the issue to be revisited, and the association’s secretary general, Tony Rice, acknowledged this momentous occasion:

“This has been a three year journey for us, from initially understanding the implications of this regulation to what we’ve achieved today – the amendment being adopted successfully. I am very grateful for the significant support received from our marine industry association members, their yards and our sister association SYBAss.

“Critical in our success was our major impact assessment comprising of three separate studies that we completed a year ago. The support of several national administrations has been fundamental to the work undertaken at IMO. In particular, I’d like to single out the Marshall Islands Registry that have submitted papers on our behalf and engaged with key flag states in the submission of these final successful amendments at MEPC 66. This five-year delay will allow the industry time to develop more optimised solutions for Tier III compliant installations on these yachts”.
