This is a review article examining ocean fertilisation as a proposed carbon dioxide removal strategy to combat climate change. The research involved a systematic review of published literature from 2001 to 2026, drawing on evidence from major international experiments including LOHAFEX, SOIREE, and EisenEx, as well as reports from the IPCC, the International Maritime Organization, the WWF, and Indian government bodies including the Ministry of Earth Sciences and NITI Aayog. The review evaluates the ecological, environmental, biological, chemical, and social consequences of ocean fertilisation, compares global and Indian perspectives, and assesses two courses of action from India's standpoint, concluding that Marine Protected Areas with blue carbon restoration represent the more sustainable and equitable alternative.
