Stop UN ‘Net Zero’ Climate Tax On American Ships

Later this week the United Nations will hold a vote on a multi-billion climate-change tax aimed squarely at American industry and commerce. If Washington does not act quickly, that levy would be written into international rules through the International Maritime Organization. The measure targets cargo and cruise ships that move roughly $20 trillion in goods across the world’s oceans.

About 80% of global trade travels by sea, so any tax at the IMO hits the bloodstream of the global supply chain. American exporters and consumers would feel that tax in higher prices and slower shipments. Turning this into a global charge enforced abroad would amount to taxation without U.S. consent.

The resolution is designed to advance the very “net zero” carbon emissions standard that has hampered European economies for years and that American voters have rejected. The idea is simple: put a price on bunker fuel and ship emissions and let an international bureaucracy decide how to spend the proceeds. That is a recipe for extra costs, red tape and politics overtaking practical solutions.

This proposal would function as a trade tax and make the planet poorer by raising the cost of moving goods. It is an international tax applied to American vessels and companies, and it slices into U.S. sovereignty. Since when should American businesses answer to a U.N. tax collector?

U.S. maritime groups estimate the plan would cost American shippers more than $100 billion over the next seven years. Forcing retirement of older vessels and mandating expensive retrofits would shift new orders to foreign shipyards. That shift threatens American jobs and the balance of maritime trade.

China dominates shipbuilding and has backed policies that would steer demand toward its yards, so the scheme risks a multi-billion-dollar transfer of business to Beijing. That outcome would reward geopolitical rivals while American firms and workers absorb the pain. Voters will rightly ask why U.S. consumers should pay to pad foreign industrial policy.

Beyond the headline numbers, the United States would have almost no say over how any collected funds are spent, which is the definition of taxation without representation in a global setting. Ports, flag states and destination authorities could enforce the charge whether the U.S. opts in or not. In short, importers and exporters would be forced to pay at foreign docks or under foreign rules.

Secretary of State Marco Rubio, Secretary of Energy Chris Wright, and Secretary of Transportation Sean Duffy have jointly stated that America “will not accept any international environmental agreement that unduly or unfairly burdens the United States or our businesses.” They call the financial impact on the U.S. of this global carbon tax “disastrous, with some estimates forecasting global shipping costs increasing as much as 10% or more.”

Although American-flag vessels account for about 12% of globally shipped merchandise, industry voices warn U.S. flags would shoulder nearly 20% of the tax burden. European and other blocs could muster votes at the IMO to push the measure through, so defections among allies make the outcome uncertain. That political reality means the White House must be ready to move now.

To stop an unfair excise on trade, the United States should threaten concrete countermeasures, starting with a dollar-for-dollar reduction in international payments until fair governance is guaranteed. Reprioritizing contributions to NATO, the United Nations, the IMF and the World Bank would send a clear signal. Economic leverage is the tool Washington should use to protect American commerce and workers.

At a time when markets are fragile and trade tensions already roil supply chains, the last thing the world needs is a U.N. excise tax on trade. Lawmakers should unite to defend sovereignty, keep shipping affordable, and block any scheme that rewards rivals at our expense. American industry and consumers deserve a government that will stand up and stop this tax.
