The extant of familiarity in the maritime industry about the Sustainable Development Goals (SDGs)

This study investigates Egyptian seafarers’ perceptions, barriers, and adoption intentions towards renewable and low-carbon energy technologies. Recognizing the maritime sector’s significant contribution to global emissions and Egypt’s strategic role via the Suez Canal, the authors conducted a cross-sectional survey of 120 seafarers covering masters, engineers, and cadets. A questionnaire gauged familiarity with renewable energy, perceived relevance to maritime work, preferred energy sources, and factors influencing choice and perceived enablers, and results were analyzed using descriptive statistics and Fisher–Freeman–Halton exact tests. Respondents showed moderate–high awareness of renewable energy. Climate change was primarily associated with sea level rise, rising temperatures, and flooding. Most participants considered renewable energy highly relevant to maritime operations, with stronger endorsement from masters and second mates than from first mates. Solar, wind, and hydrogen were viewed as having the greatest future potential, while availability and cost effectiveness were critical selection factors. Advanced technology and better training were the most valued enablers, whereas high investment costs, limited infrastructure, safety concerns, and training gaps were key barriers. The findings suggest that, although Egyptian seafarers recognize the importance of renewable energy, the main barriers consist of establishment cost, needed infrastructure, safety, and necessity for training.
