Fri Apr 11 17:28:23 UTC 2025: **US Withdraws from International Maritime Organization Climate Talks as Global Shipping Emissions Deal Reached**
London – A landmark agreement to curb greenhouse gas emissions from the global shipping industry was reached at the International Maritime Organization (IMO) this week, despite the United States’ dramatic withdrawal from the talks. The deal establishes a global fuel emissions standard, imposing fees on ships exceeding emission thresholds while rewarding cleaner fuel use.
The new regulations, set to take effect in 2028, will levy a penalty of $380 per metric tonne of excess CO2 emissions above a baseline, with an additional $100 per tonne for emissions exceeding a stricter limit. Proponents estimate this could generate up to $40 billion in revenue by 2030, a portion of which will fund the development of zero-emission fuels. The agreement aims to reduce net emissions from international shipping by 20% by 2030 and eliminate them by 2050.
The US, however, rejected the agreement, threatening “reciprocal measures” against any fees levied on US-flagged vessels. The move highlights a deep divide among nations regarding the pace of decarbonization in the maritime sector. A more ambitious proposal, championed by the EU, UK, and Pacific island nations, was ultimately rejected due to opposition from countries including China, Brazil, and Saudi Arabia. Vanuatu’s climate minister expressed disappointment, stating the adopted measures fall short of what’s needed to limit global warming to 1.5°C.
While the International Chamber of Shipping welcomed the deal, acknowledging the need to incentivize investment in zero-emission fuels, environmental groups expressed mixed reactions. The WWF lauded the agreement as a significant step but cautioned that key aspects are insufficient and could hinder the transition to a cleaner maritime industry.
The carbon pricing measure now awaits formal adoption at an IMO assembly in October.
