Two months before the IMO approves a highly debated agreement to tax excess greenhouse gas emissions, an agreement that has been criticized by some climate advocates as “too little, too late,” the Trump administration has pledged to fight the proposal and retaliate against any nation that votes in favor.
The carbon compromise agreement was reached at the 83rd meeting of the Marine Environment Protection Committee (MEPC 83), held in April, and culminated 10 years of active debate on the IMO’s climate ambitions. At that meeting, national delegates agreed on a set of binding targets for shipping greenhouse gas emissions, along with a set of emission penalties. The agreed plan focuses on a fee of $380 per ton of CO2 for exceeding a maximum emissions intensity level, plus an additional $100 per ton for exceeding a baseline level; this marginal tax structure is expected to increase operating costs and incentivize the adoption of green ships. For an IMO agreement, it was comparatively controversial: 63 nations voted in favor, 16 opposed, and 24 abstained.
Environmental critics of the agreement say it is too lenient, falls short of the IMO’s stated ambitions, and would not achieve net-zero carbon emissions by 2050. Economic critics argue it would increase shipping costs, raising the prices of transported goods. All parties agree that if it works as designed, it would result in emission reductions starting in 2030, and a statistical analysis by T&E (Transport & Environment) suggests it could halve global shipping CO2 emissions by 2040.
The Trump administration openly opposes emissions regulations, solar energy, and wind energy—three essential requirements for global carbon-neutral shipping—and has previously argued against the IMO agreement. In a recently released updated position statement, the U.S. State Department noted that the MEPC framework is a “global carbon tax” and made clear that the administration will not accept it.
“The Trump Administration unequivocally rejects this proposal before the IMO and will not tolerate any action that increases costs for our citizens, energy providers, shipping companies and their customers, or tourists. We will fight hard to protect the American people and their economic interests,” the State Department said in its statement. “Our fellow IMO members should be aware that we will seek their support against this action and will not hesitate to retaliate or explore remedies for our citizens should this effort fail.”
The MEPC 83 held last April approved a series of measures, including standard fuel regulations for merchant ships and a global GHG (greenhouse gas) emissions pricing mechanism to achieve “zero emissions” targets by 2050. The measures, once confirmed in October, would take effect in 2027 for all ships over 5,000 GT.
The Trump administration’s attitude could be a torpedo to the waterline of MEP83’s decisions.
