Paper aims: This paper aims to review the literature on the ISO 14001, an international certification for manage of Environmental Management Systems through a critical analysis of the retrieved papers based on journals in three popular databases among Brazilian researchers. Originality: The paper show the panorama of the ISO 14001 certification on companies presented in papers based in three databases with free access to the Brazilian academic community. Research method: The present work was constructed through a critical analysis, carried out in two stages: a literature review and the discussion of the selected papers. Main findings: Results showed that the benefits found by certified companies can be classified in internal, external and relations benefits. The impact of the certification on financial and organizational performances showed to be positive. Enhancement of internal processes, strengthening of results, prevention of potential problems and a larger number of stakeholders are pointed as important performance improvements. Implications for theory and practice: Present the main concepts on the role of the ISO 14001 in companies, emphasizing the importance of the standard for company performance and providing a critical analysis on the standard that has been expanding in the international market.

The industrial energetic efficiency (EE) is recognized as one of the main factors for the reduction of gas emissions that cause the greenhouse effect and for the improvement of the industrial competiveness. Within this context, many papers of the international literature have proposed different indicators of industrial, economic and environmental behavior, so as to promote the EE inside the industries. However, such proposals do not generally check the result of the joint work for more than one indicator in the organizations, making more global analysis more difficult related to EE. This paper aims to check which environmental, economic and industrial practices indicators influence the EE of the industries.  The data have been collected from the framework developed by Trianni et al. (2014), that analysed the main energetic efficiency measures for the technologies: motors, lighting, compressed air and HVAC systems (heating, ventilation and air conditioning). A logistic regression model has been adjusted for understand the relationship the economic, environmental and productive practices behavior on the energetic efficiency. Results suggest that a healthy workplace enables investments in equipment and machinery, allowing the EE inside the industries.
