Companies belonging to broadly globalized sectors are looking for keys and guidelines that will allow them to stand out from their competitors in order to win the contracts tendered on a global scale. The study conducted in this research has found the importance of following the principles of the standards of Environmental Management (EM; ISO 14001), Corporate Social Responsibility (CSR; ISO 26000), Quality Management (QM; ISO 9001), and Occupational Health and Safety Assessment Series (OSHAS 18001) in the shipbuilding industry and its relationship with firms' performance. This research proposes a new measurement index that evaluates the degree of certification of the industry over time regarding EM, CSR, QM, and Occupational Health, demonstrating a link between the evolution of companies' results (in terms of orderbooks, completions, and new orders) and the implantation of official certifications and their maturity (time elapsed since certification).
