This paper aims to analyze the impact of the adoption of ISO 14001 and ISO 9001 on the performance of Portuguese companies. The sample includes the companies listed on Euronext Lisbon, with economic, financial and specific information – the specific being environmental information and quality information – for the period between 2015 and 2019, which corresponds to the post-Troika period when some economic growth started to be witnessed. The specific information of each area is translated into the environmental certification by the ISO 14001 standard, the quality certification by the ISO 9001 standard, and sustainability reports.

To achieve this aim, four variables were used as a measure of the companies' performance, Return on Assets (ROA), Return on Equity (ROE); Tobin's Q and EBITDA Margin. With this data, different panel models were tested to validate if ISO 9001 and ISO 14001 certifications impact Portuguese listed companies performance. Specifically, the authors have used the Generalized Method of Moments, GMM-System, an estimation method proposed by Arellano and Bover (1995) and Blundell and Bond (1998).

The results show that, in general, the environment and quality variables fail to explain the dependent variables, that is, ISO certifications do not provide positive or negative variations in the performance of companies, suggesting that they are not yet as much for civil society, as well as for current or potential shareholders. When used as an independent variable, certification according to the ISO 14001 or 9001 standards, negative and significant oscillations were verified in the dependent variable, MgEBITDA, suggesting that only for managers this variable is determinant, but with a negative impact, given the high costs, it entails without pressure from other stakeholders.

This study is the first to analyze the impact of the adoption of ISO 14001 and ISO 9001 on Portuguese companies' performance. This empirical study aims to show all investors, managers, regulators and civil society itself the long path that still needs to be taken toward sustainability.

The aim of this paper is to explore the implementation of an integrated lean and ISO 14001 approach in meat industry for environmental performance and examine a proposed conceptual framework by capturing insights from lean and ISO 14001 experts in New Zealand (NZ).

Semi-structured interviews have been conducted with a group of consultants (lean and ISO 14001) to evaluate the suitability of an integrated lean and ISO 14001 approach in the meat industry for environmental performance. A conceptual framework from literature has guided this study leading to its further development based on the empirical evidence collected.

Findings have illustrated a synergistic positive impact of lean and ISO 14001 implementation as an integrated approach for sustaining environmental performance in the meat industry. A joint implementation program provides more clarity in aligning ISO 14001 operational procedures with lean tools and techniques for an enhanced environmental performance outcome.

The application of an integrated lean and ISO 14001 framework is proposed in this paper, which can help industry practitioners and academia in developing a joint implementation strategy and conducting future research.

To the best of the author’s knowledge, this study is the first to assess the effective implementation of lean and ISO 14001 as an integrated approach in the NZ meat industry.

This study aims to examine how environmental, social and governance (ESG) initiatives and ISO 14001, which is an internationally agreed standard to set out the requirements for an environmental management system, affect firm performance in the context of the Industry 4.0 supply chain.

The authors develop a new chance-constrained network data envelopment analysis (DEA) in the presence of non-positive data to estimate innovation, operational and profitability performances for three main relation groups (suppliers, partners and customers) in Microsoft's supply chain.

Results of this study show the following: (1) the application of ISO 14001 will reduce profitability but increase overall performance (OP); (2) ESG implementation has a convex U-shaped influence on profitability and OP, which means that firms will benefit when ESG investment goes beyond a particular level; (3) the nonlinear U-shape is presented in the E and G components, but not in the S of the individual ESG initiatives, and (4) only specific subcomponents of S and G in the subcomponent of individual ESG initiatives are nonlinearly connected to OP. Research's results reveal that the customer group has a higher performance value than the other two groups, which suggests that this group will create competitive advantages for Microsoft.

Overall, the authors provide an insightful viewpoint into supply chain management by examining the ESG initiatives, ISO 14001 and performances of Microsoft's supply chain.

The purpose of the study is to evaluate the compliance of environmental risk management systems implemented by Moroccan banks with ISO 14001 certification or environmental charters.

Data were collected through the distribution of an environmental risk management questionnaire to all Moroccan banks’ branches, business centers and various central entities. The study uses regression analysis to model the relationship between environmental management system (EMS) compliance and environmental management explanatory variables to identify the most relevant indicators that can explain the effectiveness and reliability of an EMS.

Empirical evidence reveals that the evaluation of EMS compliance in Moroccan banks should consider two categories of variables: the first category is related to the culture of environmental risk management, and the second one is related to environmental management practices.

The results show that the “information” variables play a key role in the overall design of an EMS and represent essential variables in the general definition of the environmental policy and in raising awareness and providing information on the bank’s commitment to a pro-environmental approach. The “application” variables confirm that environmental management practices need to be put in place to manage the different environmental risks. The study raises some managerial implications and further research directions.

This work aims to propose guidelines for small industrial businesses to take their first steps toward implementing systems, programs and tools (SPTs) for environmental management in a structured way.

The authors conducted case studies in large companies certificated ISO 14001. They ran tests for construct validity, external validity and reliability. Cross-analysis of the information collected led to identifying patterns and strategies adopted by these companies to implement environmental management. Based on the literature on environmental management in small businesses and the author's experience, the practices learned from large companies were adapted to the reality of small ones, thus resulting in the proposed guidelines.

These guidelines enable small companies to develop their environmental management following the logical evolution of SPTs: ISO 14001, green supply chain management (GSCM), cleaner production (CP) and green design (GD). The implementation should happen gradually, through the PDCA cycle, according to three specific levels of environmental evolution.

Since the guidelines focused on small industrial companies, future studies should consider other sectors, such as services, to benefit from the solutions presented. As for the implications, besides improving the small company's performance and enhancing its image, implementing the guidelines creates a green synergy along the supply chain, thus benefiting society beyond the company's borders.

The main theoretical-scientific contribution of this work is to deepen a block of knowledge that articulates environmental management and small businesses, creating a basis for further research and a reference for analyzing and discussing empirical studies in small companies. As an applied-management contribution, the guidelines allow small companies to effectively develop SPTs to move toward environmental sustainability.

Although the association between sustainability assurance (SA) quality and firm value has been examined in previous studies, the moderating relationship is novel in this study and highlights the effect of corporate environmental sustainability performance (CESP) on the relationship between SA quality and firm value. This study aims to examine whether such an effect is strengthened or weakened by eco-efficiency, as measured by ISO 14001 certification, aggregate CESP score and each individual dimension of CESP (emission reduction [ER], resource reduction [RR] and product innovation [PI]).

The sample includes 40 companies in Euronext Paris with the largest market capitalisations (the Cotation Assistée en Continu 40 [CAC 40] index) from 2010 to 2020. The authors apply the feasible generalised least squares regression technique to estimate all the regression models. Because observed associations may be biased by reverse causation or self-selection, the authors use the instrumental variable approach and Heckman two-stage estimation.

The results show that SA quality had a positive and significant effect on firm value. Second, the authors demonstrate that CESP, as assessed by ISO 14001 certification, has a stronger interaction with assurance quality and acting as a moderator variable. Using the ASSET4 scores, an alternative proxy for CESP, the authors find inconsistent evidence regarding the impact of CESP attributes. The CESP and ER scores are homogeneous and have a positive effect on firm value. However, the PI and RR CESP attributes are not homogenous and do not have the same interactive effect on firm value. The results are robust to the use of an instrumental variable approach and the Heckman two-stage estimation procedure.

Policy implications: Regulators may be interested in the findings when considering current and future assurance requirements for sustainability reporting, and shareholders when considering SA as an investment choice criterion. The insights into and enhanced understanding of the incentives for obtaining high SA quality can help policymakers develop effective policies and initiatives for SA. Considering the possible improvements in sustainability performance when obtaining a high level of sustainability verification, governments need to consider mandating SA.

Firms receive clear confirmation of the importance of investing in SA quality. Financial markets do not evaluate SA dichotomously but reward companies with higher SA quality because of the greater credibility it provides. Firms should allocate a significant percentage of their annual budgets and other relevant resources to environmental training and development programmes to improve and maintain environmental performance. If they care about environmental issues, they must announce this by issuing sustainability reports and seeking assurance of the information disclosed. High-quality assurance not only has a significant effect on investors’ investment reliability judgements but also the perceived credibility of environmental performance fully moderates the effect of assurance on these judgements.

This study has social implications; the authors find that the French market rewards firms that provide a high-quality assurance to guarantee the integrity of their sustainability reports. Therefore, by incorporating environmental sustainability into their financial goals, a better assurance ultimately will urge firms to move from green washing to strategic goals, which is beneficial for society. Further, firms that focus on sustainability as part of their business strategy may attract employees who engage in green behaviours at work and create a friendlier and productive environment because it gives meaning to the work they do and keeps them engaged to the level needed to perform their jobs capably.

This study contributes to the literature by re-examining the relationship between SA quality and firm value. It also provides new evidence on the moderating effect of CESP on the SA quality–firm value nexus. Specifically, it explores the joint effect of credibility and eco-efficiency on market confidence in sustainability information.

This study elucidates the interactive relationship of sustainability assurance (SA) quality with corporate environmental sustainability performance (CESP) and firm value and explores the moderating impact of CESP on the SA quality–firm value relationship.

The sample comprises 320 firm-year observations of 40 companies listed on the Cotation Assistée en Continu (CAC 40) from 2010 to 2019. The authors use the simultaneous equations model to capture the CESP and SA quality–firm value relationship and apply the three-stage regression and generalised method of moments approaches to address possible endogeneity.

The results show that CESP, as assessed by International Organisation for Standardisation (ISO) 14001 certification, has a significant positive effect on firm value, the relevance of which implies that in the case of good environmental performance, society's perception of a firm is much more favourable; consequently, the firm is likely to be rewarded with a premium value in capital markets. In addition, environmental performance has a stronger interaction with SA quality, acting as a moderator variable; thus, greater SA quality signals credibility owing to increased eco-efficiency. The authors interpret their findings within a multi-theoretical framework that draws insights from legitimacy, stakeholders and signalling theoretical perspectives.

This study contributes to the literature by re-examining the relationship between SA quality and firm value. It also provides new evidence of the moderating effect of CESP on the SA quality–firm value nexus. Specifically, this study explores the joint effects of credibility and eco-efficiency on market confidence in sustainability information. The authors use a simultaneous equation model to capture the reciprocal association between SA quality and firm value, whereas prior studies on SA quality and market performance have frequently used single-equation regression. The authors also find that CESP positively moderates the relationship between SA quality and firm value. Including CESP and exploring the moderating impact of eco-efficiency on the SA quality–firm value relationship is a novel approach.

This work aims to present existing management system standards (MSSs) published by the International Organization for Standardization (ISO) through a bibliometric analysis, thereby outlining their academic research status and highlighting their relation to the Sustainable Development Goals (SDGs) as well as to environmental, social and governance (ESG) themes.

The study firstly retrieves a preliminary set of MSSs standards from ISO and filters it in accordance with certain exclusion/inclusion criteria. Secondly, a bibliometric search is performed in the database Scopus. Thirdly, performance analysis is conducted to quantitatively measure the scientific output in academia, and science mapping of co-occurrences of keywords is applied to identify related topics. Thereby, the standards’ relationships to sustainability are outlined. Eventually, the work discusses future research opportunities.

The findings reveal that whereas research on MSSs focuses predominantly on only a few standards by now, there are actually numerous further standards that address sustainability-relevant topics, which are getting increasing attention among scholars as measured by the number of publications. Therefore, an action plan for future research is derived. Moreover, the findings support the argument of integrating MSSs to cover a broad range of corporate sustainability issues.

The paper connects the concepts of MSSs and sustainability, an upcoming research branch yet characterized by shortage of academic studies (given that research continues to focus on a few standards such as ISO 9001, ISO 14001 and ISO 45001). The work therefore opens up the line for more in-detail research on less known but nevertheless sustainability-relevant ISO MSSs.

The aim of this paper is to present the first diffusion analysis of ISO/IEC 27001, the fourth most popular ISO certification at global level and the most important standard for information security.

To achieve the purposes, the authors applied Grey Models (GM) – Even GM (1,1), Even GM (1,1,α,θ), Discrete GM (1,1), Discrete GM (1,1,α) – complemented by the relative growth rate and the doubling time indexes on the six most important countries in terms of issued certificates.

Results show that a growing trend is likely to be expected in the years to come and that China will lead at country level.

The study contributes to the scientific debate by presenting the first diffusive analysis of ISO/IEC 27001 and by proposing a forecasting approach that to date has found little application in the field of international standards.

Generic quality management system standard ISO 9001 and the automotive quality management system standard IATF 16949 both require organisations to demonstrate continual improvement in their customer satisfaction and the number of non-conformities identified during quality system audits. However, the long-term trends of these two parameters under ISO 9001 and IATF 16949 standards are not researched so far. It is expected that under continual improvement, organisations will achieve a step-function/stair-case shaped pattern. This study evaluates if this expectation is true when long-term performance of certified organisations is assessed.

A longitudinal exploration of three organisations certified to ISO 9001 standard and three certified to IATF 16949 standard is done. The observations are further substantiated using secondary data for the same ten years period about customer satisfaction of the major automobile manufacturers.

It is observed that none of the two indicators, i.e. the customer satisfaction and number of non-conformities, in any of the six organisations show step-wise/stair-case type improvement. All indicators followed random up and down patterns like ocean waves. It is paradoxical that certified organisations are claiming continual improvement and are remaining certified but there is actually no long-term improvement.

Longitudinal studies for the generic quality management standard ISO 9001 and the quality system standard for automotive sector IATF 16949 are rare. The revelation about ocean wave patterns observed in the long-term trends for customer satisfaction and the number of non-conformities in ISO 9001 and IATF 16949 certified organisations is a startling finding. It is outlandishly different from the conventional perception of a staircase-styled continual improvement pattern expected a priori in certified organisations.
