Scrubbers Webinar: A False Solution to the IMO’s Sulphur Cap

An online event organised by the Clean Arctic Alliance and WWF-Canada. 

Date: Tuesday 6 December 2022

Duration 1h15

This webinar focuses on how the use of scrubbers – also known as EGCS (exhaust gas cleaning systems) – have turned global shipping’s air pollution problem into an ocean pollution problem, and why use of scrubbers may conflict with UNCLOS (United Nations Convention on the Law of the Sea).

Hear from Henn Ojaveer about advice from ICES’ (International Council for the Exploration of the Sea) – the world’s oldest intergovernmental science organisation – on scrubbers, from Ida-Maja Hassellöv on the science underpinning ICES’ recommendations, and from legal expert Aldo Chirop as he explores inconsistencies between the use of exhaust gas cleaning systems and UNCLOS.
