The International Maritime Organization (IMO) was set to adopt a global carbon tax framework aimed at reducing emissions from the shipping industry, which accounts for 3% of global emissions. However, the U.S. administration's withdrawal from negotiations and subsequent pressure on other nations led to a vote to adjourn discussions for a year. The framework, which included a fee for emissions above a certain threshold, was supported by many countries and the shipping industry, which sought regulatory certainty. The delay raises concerns about international cooperation on climate change, especially with upcoming events like COP30. While cities and ports are taking steps to reduce emissions, the absence of a global framework complicates efforts to address the industry's significant carbon footprint.
