Decarbonization in the maritime industry: Factors to create an efficient transition strategy

The maritime industry faces intense scrutiny to address climate change amidst strict environmental regulations and societal expectations. The paper mainly focuses on understanding and evaluating the key factors driving the transition toward decarbonization in shipping. The study utilized qualitative analysis, focusing on reviewing current environmental targets set by major regulatory bodies, notably the International Maritime Organization (IMO) and the European Union (EU).
The study concludes that a clear strategy for reducing emissions is essential, and a holistic approach must be adopted. Thus, the investigation identified several critical factors that can facilitate the creation of an effective strategy to achieve net zero emissions, comply with regulatory goals, and reduce current emissions. They are decarbonization levels (solutions), ecosystem (value chain), and drivers (enablers), collectively referred to as the decarbonization LED model.
The study emphasizes the importance of stakeholder engagement and policy advocacy to support zero-emission transition. For instance, the paper explores the sector’s decarbonization potential through a value chain perspective (Scope 3): employing the life-cycle approach to assess the complete environmental footprint of ship – “Cradle-to-Grave” frameworks (from raw material extraction, production, and product use, until the end of its life) and “Well-to-Wake” methodology to evaluate greenhouse gas emissions from fuel production to end-use by a ship. Additionally, the paper assesses the potential impacts of environmental regulations in the maritime sector, predicting significant transformations in the industry’s operational, technological, and collaborative practices.
