From Waves to Emissions: Navigating the EU ETS in Maritime Operations

The EU ETS Expansion to Maritime

The European Union Emissions Trading System (EU ETS) has been a cornerstone of EU climate policy since 2005, covering power generation and heavy industry. With the inclusion of maritime transport from January 2024, the shipping industry now faces a carbon pricing mechanism that will fundamentally alter the economics of vessel operations within and around European waters. This expansion applies to all vessels of 5,000 gross tonnage and above, covering CO2 emissions from voyages within the EU, voyages arriving at or departing from EU ports (50% coverage), and emissions at berth in EU ports.

Phase-In Schedule

• 2024: 40% of verified emissions must be covered by European Union Allowances (EUAs)
• 2025: 70% of verified emissions must be covered
• 2026 onwards: 100% of verified emissions must be covered
• 2026: Scope expands to include methane (CH4) and nitrous oxide (N2O) emissions

Operational and Financial Implications

The financial impact of EU ETS on maritime operations depends on fleet size, trade routes, fuel types, and operational efficiency. At EUA prices ranging between EUR 50 and EUR 100 per tonne of CO2, the annual cost for a single large container vessel operating regularly on EU routes can run into millions of euros. These costs will inevitably be passed through the supply chain, affecting charter rates, freight rates, and ultimately consumer prices.

Shipping companies must establish Maritime Operator Holding Accounts (MOHAs) with the relevant EU Member State administering authority, develop approved monitoring plans, submit verified annual emissions reports, and surrender the corresponding number of EUAs by September 30th of each year. Failure to comply can result in penalties, including potential vessel detention in EU ports.

Strategies for Managing EU ETS Costs

Proactive companies are approaching EU ETS not merely as a compliance burden but as a catalyst for operational improvement. Voyage optimization, slow steaming, hull and propeller maintenance, weather routing, and port call scheduling can all reduce fuel consumption and, consequently, the number of EUAs required. Additionally, transitioning to lower-carbon fuels such as LNG or biofuels can reduce emissions intensity, and investing in energy-saving devices provides measurable returns both in fuel savings and reduced allowance costs.
