Norwegian shipping operators are pledging to cut emissions by 50% by 2030 as part of a Green Shipping Challenge agreed with the US to be announced on the sidelines of the COP27 climate talks in Egypt.

The challenge, first formulated in May by the governments of Norway and the US, will see Norwegian maritime cluster and shipping-industry organisations, shipowners, classification societies and financiers cooperate in aiming to achieve zero emissions faster than International Maritime Organization (IMO) targets.
