European Union Emissions Trading System (EU ETS)

What is the EU ETS?

The European Union Emissions Trading System, often shortened to EU ETS, is a policy introduced by the European Union to help reduce greenhouse gas emissions.

Maritime transport is included in the system through a phased introduction, with full implementation from 2026 onwards.

Under the EU ETS, ships operating to, from, or within EU ports are required to measure their greenhouse gas emissions and purchase emissions allowances that correspond to those emissions. Each allowance represents one tonne of carbon dioxide equivalent.

The aim of the EU ETS is to support the EU’s climate targets and encourage lower‑emission operations across sectors, including shipping.

Why does this apply to Aurora Expeditions?

Aurora Expeditions operates voyages that include European ports. Because of this, parts of our operations fall under the scope of the EU ETS.

For relevant voyages, we are required to:

  • Monitor and report our greenhouse gas emissions
  • Have those emissions independently verified
  • Purchase and surrender emissions allowances in line with EU regulations

What does this mean for you as a passenger?

For itineraries that fall within the scope of the EU ETS, you will see an EU ETS‑related surcharge included as part of your voyage cost.

This charge reflects a regulated cost required under European law, with the price set by the EU carbon market. 

We believe in being upfront about why this cost exists, where it goes, and what we are doing alongside it to reduce our own emissions. The EU ETS is one part of a broader global effort to reduce greenhouse gas emissions, and we see transparency as an essential part of travelling responsibly.

Where does the money go?

Revenue from the EU ETS supports Europe’s transition to a lower‑carbon future, backing projects such as renewable energy, cleaner transport, smarter buildings, and stronger energy grids. A key part of this funding flows through the EU Innovation Fund, which accelerates new low‑carbon technologies, and the EU Modernisation Fund, which helps modernise energy systems across Europe.

What is Aurora Expeditions doing to reduce carbon emissions?

Alongside regulatory requirements, we focus on practical actions that reduce emissions across our operations.

  • Modern, purposebuilt expedition ships
    Since 2020, our fleet has consisted of purpose‑built expedition vessels with X‑BOW® design, supporting improved fuel efficiency, stability, and performance.

  • Understanding our footprint
    Since 2021, we have measured our Scope 1, 2, and 3 greenhouse gas emissions, allowing us to track emissions and identify where meaningful improvements can be made.

  • Testing lowercarbon fuels
    In 2025, Sylvia Earle successfully trialled 100% biofuel made from used cooking oil, demonstrating a substantial reduction in fuel‑related emissions compared to conventional marine fuels.

  • Trialling new AIpowered route optimisation technology 
    We are the first expedition company to trial CounterCurrent’s AI‑powered ship routing, using real‑time ocean and current data to improve fuel efficiency and reduce emissions.

  • Efficient voyage planning
    We continually optimise itineraries, vessel speed and operational planning to reduce fuel use where possible.
