Efforts to establish a global regulatory framework for shipping decarbonisation are intensifying as the maritime sector approaches a pivotal decision point at the International Maritime Organization (IMO) in 2026. A coalition of 87 maritime, energy and technology companies has called on governments to adopt the proposed Net-Zero Framework (NZF), warning that delays could undermine investment momentum in low-carbon fuels and technologies. The industry argues that a clear global framework is essential to provide regulatory certainty and unlock large-scale financing for the transition to alternative fuels such as ammonia, hydrogen and e-fuels. The framework is intended to support the IMO’s broader goal of achieving net-zero greenhouse-gas emissions from international shipping around 2050, through mechanisms that could include a global fuel standard and an emissions pricing system for ships.
However, negotiations remain politically contentious. A group of countries including Panama, Liberia and Argentina has proposed an alternative approach that would remove the planned IMO decarbonisation fund and avoid a global carbon levy on shipping emissions. Instead, their proposal favours a compliance mechanism based on emissions credits trading, allowing ships that outperform emissions targets to sell surplus credits to those that fall short. Supporters argue this would reduce the financial burden on shipowners and maintain competitiveness, particularly for fleets operating under major open registries. Critics, however, warn that removing a global carbon price could weaken incentives to accelerate the shift toward zero-emission fuels and reduce funding available to support the energy transition in developing countries.
The debate highlights the growing divide between governments advocating stronger climate measures and those concerned about the economic impact of decarbonisation policies on the global shipping industry. With international shipping responsible for roughly three percent of global greenhouse-gas emissions, the outcome of the IMO negotiations is widely seen as critical to the sector’s climate trajectory. As discussions continue, both policymakers and industry stakeholders are preparing for a potential vote in 2026 that could define the regulatory framework guiding maritime decarbonisation for decades to come.
