Following the close of the COP30 climate summit, the Clean Arctic Alliance voiced strong concern over the summit’s limited progress, noting that governments missed key opportunities to act on short-lived climate pollutants—particularly black carbon emissions linked to Arctic shipping.
The Alliance highlighted that expectations for COP30 were high, yet commitments on fossil fuel reduction and rapid-impact climate measures failed to materialize. According to its Lead Advisor, the absence of urgency was especially evident in the lack of attention to “quick wins” such as reducing emissions of black carbon, a highly potent climate pollutant.
With governments now approaching a critical deadline to submit plans for reducing black carbon from Arctic shipping, the Alliance emphasized the need for swift action. Several countries used the COP30 platform to signal stronger sector-specific efforts across energy and transport, underscoring the growing awareness that cutting short-lived pollutants can deliver immediate environmental and public health benefits, particularly for Arctic communities.
A joint statement from multiple governments reinforced this urgency, noting that reducing black carbon can advance climate mitigation, strengthen resilience, improve air quality, and support sustainable development outcomes.
Growing Momentum Toward Polar Fuel Regulation
The coming weeks mark a decisive period for the maritime sector. Governments face a December 5th deadline to propose measures on polar fuels ahead of the International Maritime Organization’s upcoming Pollution Prevention and Response Committee meeting (PPR 13) scheduled for February 2026. This meeting will influence rules governing which fuels can be used by vessels operating in the Arctic in the near term.
Momentum has been building across the region, with recommendations from the Nordic Council of Ministers and renewed calls during COP30 urging recognition of cleaner polar fuels under IMO and MARPOL frameworks. Advocates argue that adopting these fuels could sharply reduce black carbon emissions, providing immediate climate and health benefits while longer-term decarbonization efforts continue.
The Clean Arctic Alliance stressed that this is a pivotal moment for leadership. By mandating cleaner fuel options for vessels in a region already experiencing dramatic climate impacts, Arctic governments and IMO member states have an opportunity to set a new benchmark for maritime environmental protection.
A Longstanding Challenge at the IMO
Black carbon has remained one of the IMO’s most enduring unresolved issues. Despite years of scientific research and technical discussions, emissions from Arctic shipping remain unregulated. The next major opportunity for progress will come in February 2026, when the IMO sub-committee will again examine the polar fuels concept.
The Alliance is urging Arctic states to champion a strong proposal that clearly identifies suitable fuels such as marine distillates DMA and DMZ or equivalents to ensure an immediate reduction in emissions. Such regulation would form the foundation for a MARPOL Annex VI approach designed to minimize the climate impact of black carbon in polar waters.
Why Black Carbon Reduction Matters Now
Black carbon is produced through incomplete fuel combustion and has an impact more than a thousand times stronger than CO₂ over 20 years. In shipping, it accounts for a significant portion of climate impact, especially in the Arctic, where its deposition on snow and ice accelerates melting and weakens the planet’s natural cooling system.
The loss of reflective ice cover exposes darker land and water, amplifying heat absorption and deepening the climate crisis—a feedback loop that scientists warn may trigger irreversible changes. The decline of Arctic ice is already reshaping regional ecosystems and global climate patterns, contributing to more extreme weather across the northern hemisphere.
Black carbon also carries serious health risks, from cardiovascular illnesses to impacts on vulnerable populations, including infants exposed through maternal inhalation. While many land-based sectors have advanced efforts to curb black carbon, similar progress at sea has lagged.
Path Forward Through Polar Fuel Regulation
Recent submissions to IMO committees underscore the case for a new MARPOL Annex VI regulation identifying polar fuels capable of delivering immediate reductions in black carbon emissions from ships operating in Arctic waters. These proposals build upon prior technical discussions and highlight the fuel characteristics needed to distinguish polar fuels from higher-emission alternatives.
Support for developing such standards has gained traction across IMO member states, as well as in parts of the fuel and maritime industries. Environmental organizations argue that the transition to cleaner fuels is not only technically feasible but essential to mitigating climate risks and protecting Arctic communities.
