The global shipping industry faces a critical moment as the United States intensifies its opposition to the International Maritime Organization’s (IMO) Net-Zero Framework, while industry leaders like Hapag-Lloyd double down on their commitment to decarbonization. With a pivotal IMO vote looming in October 2025, the debate over balancing environmental goals with economic realities is heating up.
The U.S. has formally rejected the IMO’s Net-Zero Framework, calling it a “global carbon tax” that could inflate costs for American consumers, shipping firms, and energy providers. Senior officials, including Secretary of State Marco Rubio, Commerce Secretary Howard Lutnick, Energy Secretary Chris Wright, and Transportation Secretary Sean Duffy, warned that the framework’s fuel standards and emissions pricing would harm U.S. industries and even affect cruise passengers. The administration threatened economic retaliation against countries supporting the plan, escalating tensions after the U.S. withdrew from IMO climate talks in April 2025. This stance pits the U.S. against 63 IMO member states, including China and European Union nations, who back the framework’s goal of net-zero greenhouse gas (GHG) emissions by 2050.
The IMO’s Net-Zero Framework, finalized in draft form earlier this year, sets out a global fuel standard to reduce ships’ annual GHG intensity and introduces a pricing mechanism for vessels exceeding emissions limits. Ships adopting zero or near-zero GHG technologies, such as green methanol or ammonia, would receive financial incentives. The framework builds on the IMO’s 2023 GHG emissions reduction strategy, aiming for a fair and equitable shift to sustainable fuels. A two-thirds majority of the 108 ratifying states is needed for adoption in October, and despite U.S. opposition, support from major shipping nations remains strong.
Hapag-Lloyd, a global container shipping giant based in Hamburg, Germany, has reaffirmed its support for the IMO’s decarbonization goals. The company is targeting net-zero fleet operations by 2045, outpacing the IMO’s 2050 deadline. To achieve this, Hapag-Lloyd is investing in low-emission engines, ammonia-ready vessels, and green methanol propulsion. It has secured long-term green methanol supply agreements and partnered with the Global Centre for Maritime Decarbonisation to advance sustainable fuel innovation. These efforts reflect a multi-fuel strategy, including retrofitting ships for cleaner propulsion, as part of its alignment with the Paris Agreement’s 1.5-degree Celsius target.
Addressing the U.S. rejection, Hapag-Lloyd called for science-driven, transparent discussions to counter misinformation and political delays. The company warned against incentives for crop-based biofuels, which could increase emissions and harm biodiversity if poorly managed. Instead, it advocates for advanced fuels like green methanol and ammonia as scalable, low-emission solutions. Hapag-Lloyd has also formalized CO2 reduction agreements with partners like Kuehne+Nagel and secured green financing for 24 new container ships, reinforcing its sustainability strategy.
Industry experts remain confident that the IMO’s regulations will pass, binding all internationally trading ships, including those under U.S. flags or calling at U.S. ports. BIMCO, a leading shipping association, emphasized that compliance will be unavoidable once the framework is adopted. Rico Luman, a senior economist at ING, noted that U.S. opposition could slow global decarbonization efforts, given the tight timelines for 2040 and 2050 climate targets. However, with companies like Maersk and Wallenius Wilhelmsen also committed to net-zero by 2050, the industry’s momentum toward sustainability persists.
Shipping, which carries 90% of global trade and contributes nearly 3% of global CO2 emissions, faces increasing scrutiny from environmentalists and investors. The IMO’s proposed carbon levy and fuel standards could raise costs, especially for smaller vessels, with annual fees potentially reaching millions. Yet, Hapag-Lloyd argues that balanced regulations can drive innovation without sacrificing competitiveness. Its leadership stresses the need for evidence-based policies to ensure environmental goals are feasible and effective.
As the October vote nears, the industry grapples with diverging priorities. The U.S. stance, driven by concerns over costs and competitive disadvantages, contrasts with the global push for unified emissions standards. Hapag-Lloyd’s proactive investments and advocacy for practical solutions highlight a viable path forward. The IMO’s decision will determine whether shipping can lead as the first sector with globally mandated emissions targets or face setbacks in the race to combat climate change.
