The Alliance also called for the inclusion of 1.5 degree-compatible seven per cent annual improvement in carbon intensity in the IMO's short-term measure, and for the UN's international shipping body to revise its climate targets.
Earlier this year, Arctic Foreign Ministers announced the Arctic has warmed by three degrees, while the IPCC climate report concludes that warming of 1.5 degrees and two degrees will be exceeded globally during the 21st century.
'The IPCC findings make the levels of climate ambition and timelines currently on the table for shipping at the International Maritime Organization (IMO) totally inadequate. It is imperative that measures due for adoption later this year be strengthened to ensure they drive fast deep cuts in CO2 and black carbon emissions from ships, especially those visiting the Arctic,' said Clean Arctic Alliance lead advisor Sian Prior.
'International shipping is not outside of the Paris Agreement, which covers economy-wide climate pollutants. One-fifth of shipping's climate-forcing emissions come from black carbon, and four-fifths from CO2, while impacts of black carbon emissions from ships in and near the Arctic are disproportionately greater than other black carbon emissions,' said Ms Prior.
'Black carbon is a short-lived climate forcer: Cutting black carbon emissions, especially its deposition onto Arctic snow and ice, will halt its warming impact virtually immediately,' said Ms Prior.
