Clean Arctic Alliance warns of environmental risks from Northern Sea Route shipping

The Clean Arctic Alliance has issued warnings regarding the increasing commercial interest in using the Northern Sea Route for container trade between Asia and Europe. The group highlighted recent activity, including the departure of the Liberian-flagged container ship Dubai Tower, operated by the Chinese firm Sea Legend, from Ningbo. The vessel is expected to call at ports including Felixstowe, Hamburg, and Gdynia. Additionally, South Korea’s PanStar has reportedly purchased a vessel for imminent Arctic transit.

While the route offers a shorter alternative to the Suez Canal—potentially reducing voyage times and fuel consumption amid Red Sea diversions—the Alliance warns of severe environmental consequences. Dr. Sian Prior, lead advisor to the group, stated that increased shipping activity could lead to higher pollution, loss of biodiversity, and significant climate impacts.

A primary concern is the emission of black carbon from fossil maritime fuels. When black carbon settles on sea ice, it accelerates melting, which is critical as Arctic sea ice extent is currently at its eighth lowest on record. The Alliance also noted that LNG is not a suitable alternative due to methane emissions and argued that current International Maritime Organization (IMO) measures, such as the heavy fuel oil ban, are insufficient to adequately address black carbon levels.
