Companies constantly thrive to enhance their performance in order to achieve their environmental, social, and economic goals. One way to achieve these goals is to integrate some effective management tools, such as an environmental management system (EMS), that can support sustainable development and value creation. Based on the literature, in this study some EMS integration dimensions were identified that can be used to assess its influence on business performance. The study was conducted on SMEs listed on the AeRO-Bucharest Stock Exchange that voluntary apply the ISO 14001 EMS, using a quantitative approach. To assess the EMS integration score, principal component analysis was used. Using logistic regression analysis, business performance probability (quantified by return on assets) was estimated for each company included in the final sample. Fuzzy logic was further used for modelling the influence of EMS integration on business performance probability. The research results showed that EMS integration has different effects on business performance probability, considering the influence of activity field and environmental management experience. This research assertion could be extended for all the listed Romanian companies or for major companies at the EU level.

Social, economic and environmental factors contribute to the companies’ sustainable development. Social and financial dimensions have an important contribution to sustainable performance, through assurance of transparency in the information communication requested by stakeholders in order to substantiate their decisions. Social transparency is ensured by presenting organization’s actions in the field of social responsibility, and financial transparency takes into account the most accurate, complete and neutral presentation of information, both in the annual financial statements and in the audit reports. The present study aims to assess the influence of financial transparency and gender equality on the sustainable corporate performance, thus contributing to increasing SDGs awareness and achievement required by 2030 Agenda. Through a sample of 1133 observations (Romanian listed companies/years) to the period 2008–2020, the obtained research results emphasis that gender equality and absence/presence of transparency in financial reporting have a significant influence on corporate sustainable performance.
