Greece, one of the world’s biggest maritime powers, is set to abstain from a key vote on a global carbon tax for shipping, signaling a retreat from previous support for an International Maritime Organization (IMO) plan to make the sector pay a price for carbon emissions.

According to a person familiar with the matter, Athens now intends to withhold its vote on the proposal, which aims to impose fees on marine emissions exceeding one billion tons annually. This shift highlights growing concern within the world’s second-largest shipowner country about the potential economic repercussions of this measure.
Greece had previously voted in favor of a draft version of the framework in April, but the government has since backed away from the plan, questioning its feasibility and cost implications for global airlines. “Athens has long been skeptical of the net zero framework and its impact on the shipping industry,” the source said. The Greek government declined to comment publicly.
The vote comes as geopolitical tensions over marine decarbonisation worsen. While the European Union urges member states to support a carbon tax, the United States remains strongly opposed. Washington has warned that it may retaliate with tariffs, visa restrictions and port fees if the IMO continues to act. It also proposed adding another procedural step before the accusation could take effect, effectively delaying its implementation.
Greece’s decision to abstain from voting would constitute a departure from the EU’s unified position on climate leadership. The European Commission last week described the IMO’s net zero plan as an “important milestone” towards decarbonizing global shipping and ensuring fair competition.
Greek officials have reportedly conveyed their reservations to EU authorities in writing, citing concerns about the availability and cost of clean marine fuel. “The framework relies on technologies that are not yet widely applicable,” the source said. “It penalizes companies that do not have access to alternative fuels, leading to higher costs as shipowners compete for limited supplies.”
The outcome of this week’s IMO vote remains uncertain, especially amid US resistance and differing views among major maritime nations. In April, a draft plan received widespread international support, but industry concerns about cost, compliance and competitiveness have grown since then.
Greece ranks as the second largest ship-owning country in the world – behind only China – according to data from research firm Clarkson Services. Its position carries great weight in shaping the direction of global maritime policy, especially within Europe’s powerful shipping community.
