This paper aims to analyse the bibliometric characteristics of the ISO 50001 publication, map the state of the art of the research topic and identify future research issues.

This research is a bibliometric study. The data were collected from Scopus. Both performance and science mapping analysis were performed.

The research results showed the top author, paper and country of ISO 50001 publications. There are four author collaboration clusters and five country collaboration clusters. Eight research themes were mapped into four quadrants based on the density and centrality. The bibliometric coupling analysis showed six research clusters. Finally, the research issues were mapped. The implications were discussed.

This research gave several implications for researchers, practitioners and public policymakers. For researchers, the bibliometric analysis provides several research issues that can be followed up by future research. For practitioners, the bibliometric analysis showed that applied tools and methods that can assist the implementation of ISO 50001-based energy management have been developed. For public policymakers, the bibliometric analysis offered the knowledge structure on ISO 50001 that can be used in public policymaking development. The author collaboration cluster and the bibliometric coupling cluster can be used to trace the scientific information that is needed as the foundation of public policy.

Many ISO 50001 studies have been performed. However, based on the search in several main academic scientific paper databases, there is no bibliometric study on the research topic. This is the first bibliometric study on ISO 50001 publication. This study takes a holistic approach combining performance analysis and science mapping analysis that includes elaborated thematic mapping and evolution analysis.

This article aims to optimise energy use and consumption by integrating Lean Six Sigma methodology with the ISO 50001 energy management system standard in an Irish dairy plant operation.

This work utilised Lean Six Sigma methodology to identify methods to measure and optimise energy consumption. The authors use a single descriptive case study in an Irish dairy as the methodology to explain how DMAIC was applied to reduce energy consumption.

The replacement of heavy oil with liquid natural gas in combination with the new design of steam boilers led to a CO₂ footprint reduction of almost 50%.

A further longitudinal study would be useful to measure and monitor the energy management system progress and carry out more case studies on LSS integration with energy management systems across the dairy industry.

The novelty of this study is the application of LSS in the dairy sector as an enabler of a greater energy-efficient facility, as well as the testing of the DMAIC approach to meet a key objective for ISO 50001 accreditation.

Exploring the Lean and Green relationship goes back to the beginnings of Lean manufacturing. Most cases established that companies implementing Lean have Green results. However, there are Lean practices with a higher impact on Green, but others with less impact. Therefore, this paper presents research that explores the relationship between Lean and Green in manufacturing companies and aims to determine whether Lean practices have a higher association with Green aspects.

A survey was conducted amongst manufacturing firms to determine their Lean Index (LI). The internally related elements of the Lean construct determined each firm’s LI, whilst Cronbach alpha determined internal LI consistency. The survey also identified firms developing six Green aspects: International Organisation for Standardisation (ISO) 14001, ISO 50001, general Green aspects and the specific aspects of materials, energy and water. An individual sample t-test shows different LI levels of association for each Green aspect. Binomial logistic regression shows the LI element association for each Green aspect.

LI is higher at firms reporting the inclusion of Green aspects. More than half of LI components have a statistically relevant association with the six Green aspects. In general, Ishikawa diagrams had the highest association with Green aspects whilst the lowest was seen in workers as improvement initiators. By grouping the LI elements into their categories, the Lean practices related to controlling processes have a higher association, whilst the involvement of employees has the lowest.

Further research found in this paper identifies the possibilities for investigating the specificities of each Lean tool to develop Green aspects in companies.

Practitioners learn that Lean and Green are not separate issues in business. This article provides evidence that Lean practices in place at companies are already associated with Green aspects, so integration may already be happening.

This paper provides specifics on the relationship between each Lean practice and developing Green aspects. Thus, this paper specifies the Lean practices that contribute most to Green efficiency to support the joint development of both themes.

This investigation aims to reframe the sizeable literature on barriers and drivers for energy efficiency measures (EEMs) and the phenomenon of the energy efficiency gap. The authors identify a gap between academic methods and industrial needs, as well as a neglect of the cultural dimension, despite its considerable impact. On the basis of this insight, the purpose of this paper is to integrate all of the various influences on industrial energy behavior previously identified in the literature in a refined energy cultures framework.

This paper includes a systematic literature review of research in the field of energy management, energy efficiency and cultural aspects within barriers and drivers of energy behavior. The authors select and refine an existing energy cultures framework for the industrial context. To meet industrial needs, the authors applied an ontology mapping of its core elements onto an international standard common for industrial energy management practice.

First, the authors present a refined framework for industrial energy cultures incorporating past barriers and drivers as factors. The framework enables an evaluation of attitude and behavioral aspects, underlying technologies, organizational culture and actions related to energy as a system of interdependencies. Second, the factors are ranked on the basis of the number of appearances and empirical metadata. Economic aspects such as “purchase, installment and hidden costs”, “general investment and risk behavior” and “regulatory conditions” are the highest ranked factors, but “existing knowledge about EEM”, “hierarchy approach: top down” and “environmental concerns” follow closely and represent cultural aspects, which are still underrated. Third, while illustrating a successful mapping onto a standardized process of continuous improvement, the authors also argue for heightened academia–practice efforts.

Reframing the energy efficiency gap as a problem of what aspirations play a role, what technology is chosen and how technologies are used should increase the level of implementation of EEMs in the real business world. Introducing the refined energy cultures framework serves as a starting point for future transdisciplinary collaboration between academia and practice.

Targeting the energy efficiency gap is an essential part of the sustainable development goals. The refined energy cultures framework allows for a better understanding of the industrial energy behaviors that are responsible for a significant share of a company’s success. The introduction of energy cultures serves as a starting point for future scholarly research within sustainability management accounting.

The investigation combines existing research streams, their concepts and their results about cultural aspects related to energy efficiency for both academics and practitioners. This review is the first to capture all of the various factors analyzed in academic literature using the energy cultures framework as a basis. The authors add to the theoretical development of that framework with its application to the industrial context. This is identified as a gap. Its refinement helps to holistically understand barriers and drivers of industrial EEMs to support its practical implementation.

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.

This paper attempts to explore the green-lean-six sigma (GLSS) practices in the continuous process industry particularly in the flexible packaging (FP) industry in an emerging economy for addressing environmental sustainability issues.

The authors have employed a qualitative multiple-case approach to examine managerial perspectives on GLSS adoption in the flexible packaging industry. Semi-structured interviews with senior corporate managers in two large FP organizations in Pakistan were conducted as the primary source of data collection.

Drawing on the natural resource-based view (NRBV), the analysis revealed that organizations are implementing key GLSS practices such as environmental management system (ISO 14001), cause–effect analysis, renewable energy sources, total productive maintenance, and statistical process control to effectively manage waste, conserve resources, control air emissions, and improve environmental and workplace safety.

The authors argue that this is one of the first research studies that has utilized NRBV to investigate the application of the GLSS approach in the process industry, specifically in the FP industry in an emerging economy.

Despite differing strategies towards environmental sustainability in developed and developing nations, the manufacturing sector in these regional domains faces substantial environmental issues. The purpose of this study is to examine the green-lean-six sigma (GLSS) enablers and outcomes for enhancing environmental sustainability of manufacturing firms in both, a developed and developing country context by using an environment-centric natural resource-based view (NRBV).

First, a framework of GLSS enablers and outcomes aligned with the NRBV strategic capabilities is proposed through a systematic literature review. Second, this framework is used to empirically investigate the GLSS enablers and outcomes of manufacturing firms through in-depth interviews with lean six sigma and environmental consultants from New Zealand (NZ) and Pakistan (PK) (developed and developing nations).

Analysis from both regional domains highlights the use of GLSS enablers and outcomes under different NRBV capabilities of pollution prevention, product stewardship and sustainable development. A comparison reveals that NZ firms practice GLSS to comply with environmental regulatory requirements, avoid penalties and maintain their clean-green image. Conversely, Pakistani firms execute GLSS to reduce energy use, satisfy international customers and create a green image.

This paper provides new insights on GLSS for environmental sustainability which can assist industrial experts and academia for future strategies and research.

This is one of the early comparative studies that has used the NRBV to investigate GLSS enablers and outcomes in manufacturing firms for enhancing environmental performance comparing developed and developing nations

The purpose of this paper is to present a case study regarding the deployment of a previously developed model for the integration of management systems (MSs). The case study is developed at a manufacturing site of an international enterprise. The implementation of this model in a real business environment is aimed at assessing its feasibility.

The presented case study takes into account different management systems standards (MSSs) progressively implemented, along the years, independently. The implementation of the model was supported by the results obtained from an investigation performed according to a structured diagnosis that was conducted to collect information related to the organizational situation of the enterprise.

The main findings are as follows: a robust integrated management system (IMS), objectively more lean, structured and manageable was found to be feasible; this study provided an holistic view of the enterprise’s global management; clarifications of job descriptions and boundaries of action and responsibilities were achieved; greater efficiency in the use of resources was attained; more coordinated management of the three pillars of sustainability – environmental, economic and social, as well as risks, providing confidence and added value to the company and interested parties was achieved.

This case study is pioneering in Portugal in respect to the implementation, at the level of an industrial organization, of the model previously developed for the integration of individualized MSs. The case study provides new insights regarding the implementation of IMSs including the rationalization of several resources and elimination of several types of organizational waste leveraging gains of efficiency. Due to its intrinsic characteristics, the model is able to support, progressively, new or revised MSSs according to the principles of annex SL (normative) – proposals for MSSs – of the International Organization for Standardization and the International Electrotechnical Commission, that the industrial organization can adopt beyond the current ones.

The purpose of this paper is to develop a strategic approach with an intelligently integrated management system in advanced manufacturing industry to meet the requirements of high precise measurement tasks and essential measurement know-how within the sophisticated production systems.

The continuous development toward ever-higher precision and closer tolerances in the manufacture of workpieces is in line with the perspective of nanotechnology. To meet the metrological requirements new high precision intelligent measuring instruments have been developed, which are proposed in this paper.

In modern industrial production, need for high precision metrology at micro and nano scale provides high quality requirements as well. Therefore, while providing adequate metrology applications, good management of resources and environmental, energy consequences shall be addressed in an integrated manner with an integrated management system of quality, environment and energy.

Metrology as the measurement science provides the functional methodology for quality control under the defined specifications and standards. New levels of manufacturing precision are the key requirements to enable advanced machining processes that demands improved techniques of metrology.

The practical industrial use is now quite possible, but uncertainty and calibration with respect to certain questions still open. In various technical fields, there are increasingly new applications being mainly mechanical engineering, precision machining, biomedicine and precision engineering are mentioned.

This paper provides measurement results and experimenting a strategic approach to develop a smart integrated system applicable in manufacturing industry using the intelligent networking for the digital factory by first an inter-university network that accesses, cooperates and operates at distance in the laboratory of distant research laboratories that can be applicable to all other industrial organizations.

The purpose of this paper is to study how the expression “integrated management systems” is interpreted in literature, what it means to have an integrated management system (IMS) and what the results of this are.

A literature review was conducted based on Scopus using the search term “Integrated Management Systems.” In the chosen articles, effects of integration, scope, level and extent of integration and if the approach is inside-out or outside-in, have been analyzed.

Most articles on IMS conclude that integration is beneficial regarding cost saving, operational benefits and improved customer satisfaction. The general approach in the articles, describes an inside-out approach with focus on integrating existing management standards. The scope of integration covers typically management systems for quality, environment and occupational health and safety.

An IMS is found to be a system that integrates existing management standards based on an inside-out approach. This indicates possibilities for both practical improvement and research in exploring how integrated stakeholder needs could be managed, possibly as process-based IMSs.

This paper sheds light on the ambiguous interpretation of the IMS concept.
