Reduction of Greenhouse Gas (GHG) Emissions​

Reducing GHG Emissions – a Commitment

Climate change is affecting the Arctic at a far greater rate than the rest of the world. Scientific assessments indicate that the region is warming nearly four times faster than the global average, with some Arctic sub‑regions experiencing even higher rates. These changes have far‑reaching consequences for Arctic ecosystems, communities, and the conditions under which expedition cruise operations take place.​

AECO’s members are committed to reducing their environmental footprint and taking early,concrete action to limit greenhouse gas emissions. In 2017, AECO signed the Arctic Commitment, calling for a complete phase‑out of heavy fuel oil (HFO) in Arctic shipping. In 2019, AECO members went further by approving a self‑imposed, voluntary ban on the use of HFO, five years ahead of the International Maritime Organization’s (IMO) ban.​

Building on this, in 2024 AECO members unanimously agreed to track and reduce their greenhouse gas emissions through a shared GHG Reduction Commitment. This commitment reflects a common understanding that credible climate action requires transparent measurement, consistent reporting, and long‑term reduction efforts across the expedition cruise fleet.​

To support this transition, AECO developed the Roadmap to GHG Emission Reduction that roadmap brings together up‑to‑date guidance and recommendations from organizations such as the IMO, CLIA, and DNV. It provides practical support on emissions‑calculation methodologies, carbon budgeting, operational measures, and technological upgrades that can help reduce greenhouse gas emissions. ​

Together, these efforts aim to support continuous improvement while maintaining safe and responsible expedition operations in the Arctic.​
