IMO Advances Net Zero Framework Despite Delays
As the International Maritime Organization’s (IMO) Intersessional Working Group on Reduction of Greenhouse Gas (GHG) Emissions from Ships (ISWG-GHG 20) wraps up its meeting in London, the Clean Shipping Coalition (CSC) commends member states for their commitment to progress. Despite a recent decision to postpone the adoption of the Net Zero Framework (NZF) for a year, discussions have moved forward, focusing on the necessary guidelines for future implementation.
Progress Amidst Setbacks
Last week, the IMO’s decision to delay the adoption of the Net Zero Framework was met with disappointment. However, Delaine McCullough, president of the Clean Shipping Coalition, emphasized that this delay is not a defeat but rather a temporary setback. “During this week’s ISWG meeting, IMO member states have constructively engaged in preparing the guidelines that will be necessary once the NZF is adopted,” she stated. This indicates a strong commitment to the framework and a willingness to continue preparations for its eventual implementation.
The Net Zero Framework aims to significantly reduce greenhouse gas emissions from ships, aligning with the IMO’s broader GHG Strategy. Key components of the NZF include a global fuel standard (GFS) that mandates a gradual reduction in the pollution levels of ship fuels. This standard will also introduce a pricing mechanism for GHG emissions, incentivizing the shipping industry to adopt cleaner practices. John Maggs, the Clean Shipping Coalition’s representative at the IMO, highlighted that member states do not need to wait for the NZF to take action. He pointed out that at the upcoming MEPC 84 meeting in April 2026, there will be opportunities to enhance the Carbon Intensity Indicator (CII), a crucial measure for improving energy efficiency in shipping.
Future Directions and Innovations
Despite the postponement of the NZF, discussions at the ISWG meeting advanced on essential implementation guidelines. Dr. Alison Shaw, IMO Manager at Transport & Environment, noted that the framework’s success will depend on coherent guidance that promotes sustainable fuel production while preventing environmental harm. Many member states recognized the need for a balanced approach that considers both environmental impacts and social equity, as highlighted by Andrew Dumbrille, Co-Founder and Director of Equal Routes. He stressed the importance of creating a fair pathway for the shipping sector to achieve its net-zero goals by 2050.
Wind propulsion technology has also gained renewed attention, with support from various countries and industry data reinforcing its potential. Anaïs Rios, Senior Shipping Policy Officer at Seas At Risk, remarked that while the Net Zero Framework may be delayed, the momentum for implementing wind propulsion solutions remains strong. She urged governments to ensure that guidelines facilitate the widespread adoption of this technology, which can significantly reduce emissions and operational costs. Jenny Helle, an expert on decarbonization, warned against scaling back ambitions at this critical juncture, emphasizing the need for clear, enforceable guidelines that support the transition to cleaner shipping fuels and technologies.
