International NGOs led by the Clean Arctic Alliance have sent an urgent letter to International Maritime Organization (IMO) Secretary-General, Mr Kitak Lim, urging him to address the international shipping’s climate impact. The letter, which was also sent to European Council President Michel, President of the European Commission von der Leyen and European Commission Executive Vice President Timmermans, comes ahead of Friday’s crucial decision on IMO measures on black carbon emissions in the Arctic.
