The fact that numerous industries rely heavily on metals underscores the need to address corrosion as a common and costly process. Conventional corrosion inhibitors (CIs) have been employed to mitigate metal degradation and associated economic losses. However, their environmental and health hazards have driven a global shift toward sustainable alternatives. This review critically examines green corrosion inhibitors (GCIs), focusing on their sources, mechanisms, performance, and industrial applicability. Derived from natural compounds such as plant extracts, essential oils, amino acids, and biopolymers like starch, cellulose, lignin, and gums, GCIs are categorized based on their chemical nature, adsorption behaviour, and inhibition mechanisms consistent with green chemistry principles. This review also notes the practical challenges of implementing GCIs, namely synthesis, standardization, operational efficiency, and compliance with national regulations, as well as advances in hybrid (natural + synthetic) corrosion inhibitors and predictive modelling. Furthermore, GCIs are evaluated against key Sustainable Development Goals (SDGs), with applications spanning the oil and gas, water treatment, construction, and marine engineering sectors. The review also identifies key weaknesses of GCIs, such as inherent variability, limited solubility, and challenges in large-scale production. Future directions include chemical modifications to enhance performance, blending low concentrations of GCIs with CIs to develop synergistic formulations, and utilizing molecular data to advance a rational design approach. In summary, this directive review pulls together interdisciplinary knowledge to enhance the rational process of developing and implementing eco-friendly approaches to mitigate corrosion.
