EU-US rivalry over maritime carbon pricing exposes deeper systemic fractures in global climate governance and trade asymmetries

Indigenous maritime cultures, such as the Māori waka voyagers and Pacific Island navigators, have sustained low-carbon shipping for centuries through renewable energy (wind, wave) and seasonal route optimization. Their knowledge systems prioritize ecological balance over profit, offering alternatives to carbon-intensive global trade. However, these perspectives are systematically excluded from climate policy debates, which favor technocratic solutions over traditional ecological practices.

The conflict echoes historical trade disputes, such as the 19th-century Corn Laws or the 20th-century steel tariffs, where industrialized nations imposed unilateral trade measures to protect domestic industries. The EU’s ETS extension to shipping is a modern iteration of this pattern, where climate policy becomes a tool for economic protectionism. It also mirrors the post-colonial trade imbalances, where Global South nations are penalized for emissions tied to colonial-era resource extraction and trade routes.

In South Asia, where dhows and traditional sailing vessels still operate, the carbon levy is viewed as a neocolonial tool that could erode local maritime economies without addressing the disproportionate historical emissions of the Global North. African Union negotiators have proposed a 'climate reparations' fund for maritime emissions, arguing that the levy should be tied to development aid rather than punitive measures. Chinese state media frames the EU’s move as hypocritical, given Europe’s reliance on Chinese-built ships and its own historical carbon debt.

Scientific consensus supports carbon pricing as an effective tool for decarbonizing shipping, but the EU’s unilateral approach risks carbon leakage and trade distortions. Studies show that maritime emissions are concentrated in a few Global North-owned shipping companies, while the majority of emissions are generated in the Global South due to trade imbalances. The IMO’s current carbon pricing proposals lack the equity mechanisms needed to address these disparities, relying instead on voluntary market-based solutions.

Artistic and spiritual traditions across maritime cultures frame the ocean as a living entity deserving of care, not exploitation. Polynesian navigators, for example, see the sea as a sacred ancestor, while Scandinavian seafaring sagas depict storms as moral reckonings for greed. These perspectives challenge the commodification of shipping and advocate for regenerative maritime practices, but they are rarely integrated into policy frameworks.

Future scenarios suggest that without equitable carbon pricing, the EU’s levy could trigger a race to the bottom, where shipping companies flag out to non-ETS jurisdictions or rely on carbon offsets of dubious integrity. A more robust system would include a global maritime carbon fund, with revenues redistributed to Global South nations based on historical emissions debt and developmental needs. Alternative models, such as the 'degrowth' shipping proposals from degrowth economists, advocate for localized, low-carbon maritime trade networks.

Marginalized voices include Small Island Developing States (SIDS), which face existential threats from rising sea levels but lack representation in EU-US negotiations. Artisanal fishermen in West Africa and Southeast Asia, who contribute minimally to emissions, are disproportionately affected by fuel price hikes and trade restrictions. Women, who make up 30% of the global maritime workforce but are often invisible in policy discussions, are particularly vulnerable to job losses from carbon pricing without just transition mechanisms.
