Environmental Disclosure of Fuel Station Companies in the Municipality of Mossoró/RN Based on the Corporate Sustainability Index—ISE

The retail fuel trade in urban areas presents relevant environmental risks, requiring systematic sustainability assessments. This study aims to highlight the socioenvironmental performance of gas stations in Mossoró, RN, using the Corporate Sustainability Index (ISE). It is a descriptive and exploratory case study based on questionnaires administered to managers of 12 licensed stations. The ISE was calculated from 17 environmental, legal, social, and operational indicators, equally weighted. The results indicated a predominance of high sustainability performance, with 91.7% of the enterprises presenting an ISE above 75%, associated with operational organization, preventive practices, and compliance with legal requirements. However, part of the actions remains tied to regulatory compliance, revealing a predominantly reactive environmental management profile. This study provides support for improving strategic environmental management in the urban context of Brazil’s semi-arid region.
