Norway’s shipping industry emits about 10 million tons of CO2 annually, making it one of the country’s largest carbon sources. While zero-emission vessels and green fuels remain essential for long-term climate goals, experts say immediate cuts are possible through energy efficiency measures that reduce fuel use without waiting for new technology.
A new report from the Norwegian Maritime Authority highlights that retrofitting older ships with smart routing systems and optimized hull designs can lower fuel consumption by 10 to 15 percent. These changes require no new infrastructure and rely on existing technology already proven in commercial operations. Ports in Oslo and Bergen have begun offering incentives for ships that adopt such upgrades, signaling growing industry interest.
The report also notes that slow steaming—reducing vessel speeds by just 10 percent—cuts emissions by around 20 percent. This practice has gained traction among European ferry operators, including Fjord1, which reported a 15 percent fuel reduction across its fleet after implementing speed limits. Such measures provide quick wins while the sector awaits breakthroughs in hydrogen and ammonia-powered engines.
Shipping accounts for nearly 3 percent of global greenhouse gas emissions, according to the International Maritime Organization. Norway, a global leader in maritime innovation, has set a target to halve emissions from domestic shipping by 2030. Achieving this will require both immediate efficiency gains and long-term investments in alternative fuels.
Industry leaders stress that waiting for perfect solutions is not an option. ‘We can’t afford to delay action,’ said a spokesperson for the Norwegian Shipowners’ Association. ‘Every ton of CO2 saved today is a step closer to our climate goals.’
