Shipping companies in Cyprus and Greece are facing significant uncertainty over future carbon pricing as the International Maritime Organisation (IMO) considers four rival proposals. These proposals range from no direct greenhouse gas charges to a steep Tier 1 compliance price of $300 per tonne of CO2 equivalent, which could drastically affect operating expenses, investments in cleaner fuels, and the commercial viability of older vessels. The IMO framework, approved in principle for implementation in April 2025, aims to regulate emissions from large ocean-going ships but remains subject to ongoing negotiations.

At the core of the debate is how much ships should pay for pollution and who ultimately bears the costs. Tuvalu advocates for the highest carbon price and stricter compliance, which would increase transport costs substantially but generate more funds for green initiatives and support for developing nations. Conversely, Liberia proposes eliminating direct carbon charges in favor of a tradable credit system to avoid penalizing ships when low-emission fuels are scarce or costly. Brazil and a coalition including Australia, Canada, South Africa, and the UK propose moderate adjustments to compliance timelines and targets.

The outcome will directly influence Cyprus and Greek shipmanagement decisions on newbuilds, fuel choice, and retrofits amid overlapping EU carbon regulations. Industry voices emphasize the need for coordination to avoid double payment under the EU Emissions Trading System and IMO pricing, calling for transparent reconciliation mechanisms. The IMO will continue deliberations through late 2024 before finalizing a binding mechanism.
