Talks at the International Maritime Organization (IMO) regarding the adoption of new global rules to reduce greenhouse gas emissions from shipping concluded on Friday without reaching an agreement. Delegates decided to postpone any decisions on the proposed Net-Zero Framework for 12 months, reflecting significant divisions among countries over the proposal.
The IMO’s Marine Environment Protection Committee (MEPC), which reconvened this week in London, adjourned its extraordinary session with plans to regroup in a year. During this time, nations are expected to engage in ongoing discussions aimed at reconciling differing views on the framework, which is designed to align the shipping sector with global commitments towards achieving net-zero emissions by 2050.
The draft framework, previously approved in principle last April, aims to amend the MARPOL treaty by establishing a global fuel standard and an associated pricing mechanism for greenhouse gas emissions from ships. The shipping sector contributes nearly three percent to global emissions, and should the framework be implemented, it would signify the first legally binding global system to curb emissions from maritime activities.
In his closing remarks, IMO Secretary-General Arsenio Dominguez highlighted the need for collaborative effort, urging delegates to rebuild trust and seek a consensual path forward. He emphasized that despite differing opinions, there was collective support for the organization’s work. Dominguez advised against celebrating the adjournment, noting the persistent concerns that require attention and cooperation among members.
UN Spokesperson Stéphane Dujarric remarked that Secretary-General António Guterres viewed the lack of agreement as a “missed opportunity” for member states to place the shipping industry on a credible trajectory towards net-zero emissions. Dujarric underlined the critical importance of decarbonizing the maritime sector, which is responsible for about 80 percent of global trade.
Significant opposition from major economies, including the United States, has complicated discussions. Critics argue that the proposed global pricing mechanism may act as a “carbon tax,” potentially increasing shipping costs by over 10 percent. Nonetheless, the IMO has announced plans for a working group next week to continue developing technical guidelines for the implementation of the framework.
Amidst the challenges, there is a prevailing sense of hope that ongoing consultations can lead to a more unified stance on emissions reduction within the shipping sector. This potential aligns with previous discussions emphasizing the urgent need for equitable solutions that acknowledge the vulnerabilities of nations most affected by climate change. As the global community looks towards the future, the possibility for a collaborative approach remains, highlighting the importance of environmental stewardship and justice in navigating the complexities of climate action in the maritime industry.
