New York-listed diversified tanker company International Seaways has made its first disclosure of carbon emissions from its fleet with a number that is slightly worse than the IMO's targets for 2019.

The Lois Zabrocky-led owner said in a two-page report posted to its website that it achieved a "fleet sustainability score" of 1.06, "indicating that for 2019, the carbon emissions for the fleet was 6% over the IMO trajectories for the year".
