A pivotal phase for shipping
Shipping’s transition to net zero is underway. With practical actions and a willingness to adapt, the industry can convert readiness into measurable results

T he global shipping industry is at a pivotal phase in its decarbonisation journey. Against the backdrop of unpredictable geopolitics and a turbulent global economy, shipping – a sector responsible for nearly 3% of global greenhouse gas (GHG) emissions – faces strong pressure to transform. Drawing on research, industry data, and practical experience, the latest Maritime Forecast to 2050 report from DNV reveals a sector that is increasing its technical readiness for a low-carbon future yet still facing significant hurdles in translating this into real emissions reductions. While the International Maritime Organization’s (IMO) goals – which include achieving net zero ‘by or around’ 2050 – may seem lofty and highly ambitious, several different pathways can lead shipowners to significant emissions reductions over the coming years and decades (see Figure 1 ). However, this will require cross-industry collaboration, major infrastructure development, and regulatory clarity, which will
biodiesel, an emerging portion of the fleet has the capability to do so using alternative, non-oil fuels, such as liquefied natural gas (LNG), methanol, liquefied petroleum gas (LPG), ammonia, or hydrogen. As shown in the Maritime Forecast to 2050 , by 2030 alternative- fuel capable vessels will have the capacity to burn around 50 Mtoe per year of non-oil fuels, a significant portion of the total annual fuel consumption of 280 Mtoe. In 2024, the industry saw a record uptake of alternative-fuel capable vessels (see Figure 2 ). As shown in DNV’s Alternative Fuels Insight (AFI) platform, 515 vessels with alternative-fuel (mainly dual-fuel) capability were ordered in 2024, representing a 38% increase compared to 2023. The majority of these (67%) were for LNG-fuelled vessels in the container segment, as shipowners demonstrated an attraction to a fuel that can provide immediate GHG reductions (up to around 20%) while also offering a potential pathway to net zero through the eventual use of low-GHG versions,
