The regulation plan, initially proposed in 2018, set a target year of 2026 while acknowledging the need for technological advancements. The Storting (Norway’s Parliament) has now established a phased implementation schedule. According to the new rules, cruise ships and ferries under 10,000 gross tons must operate with zero emissions by January 1, 2026. For larger vessels, the deadline has been extended to January 1, 2032, to accommodate the current limitations in zero-emission technology for such ships.

Norwegian Climate and Environment Minister Andreas Bjelland Eriksen stated that the regulation aims to "drive technology and contribute to the development of zero-emission solutions." The government has been actively supporting advancements in alternative power sources, including hydrogen and high-capacity batteries.

The phased timeline and extended deadline for larger ships reflect an understanding that "sufficient technology does not yet exist for the largest ships." The regulations will also allow the use of biogas to meet the emission standards, and operators like Havila are already experimenting with battery power. Notably, in June 2022, the 15,800 gross ton Havila Castor achieved a record by operating solely on batteries for three hours in Geirangerfjord.

Additionally, Norway is introducing rules to promote the use of shore power where available. The Storting has mandated the establishment of onshore power in Flam, a popular cruise destination within Aurlandsfjord, a branch of the Sognefjord. The government will provide funding to support this infrastructure development.

Starting in 2024, Norway ended an exemption for cargo ships in the Arctic from a 2022 ban on heavy fuels. The first penalties for non-compliance were imposed this summer. The ban, aimed at preventing oil spills in the Arctic's sensitive environment, has also led to a reduction in emissions in the region.

The move comes amidst a surge in cruise ship visits to Norway. Following the pandemic, the number of cruise tourists has significantly increased. The Cruise Norway association reported over six million cruise passengers in 2023, a 33% rise from the previous year, and anticipates a further four percent growth in 2024, alongside an increase in ship calls.
