Voluntary environmental management system standards: Case studies in implementation

Many anticipate that over the next decade, voluntary environmental management system (EMS) standards will take on the same importance in the marketplace as the ISO 9000 quality standards; the draft international EMS standard (ISO 14001) is on pace to be completed by mid-1996. In the United States, despite rapidly growing interest in EMS standards, most companies and regulatory agencies are uncertain about their potential benefits and about the process of developing an EMS. Case studies of EMS implementation, particularly in small and medium-sized companies, are needed to demonstrate the process and identify areas in which further EMS guidance is needed for environmental managers. This article presents seven case studies of EMS implementation in small, medium-sized, and large companies. Each company is participating in an EPA-sponsored Demonstration Project in which a variety of organizations are piloting the implementation of EMS standards (the project is being coordinated by NSF International, a not-for-profit company specializing in environmental and public health standards and certification). The case studies, written by the companies themselves, share experiences of EMS assessment, planning, and implementation, and discuss challenges that are special to particular industries.     

Influence of Motivations for Seeking ISO 14001 Certification on Perceptions of EMS Effectiveness in China

This study examines the motivations of mainland Chinese facilities in seeking ISO 14001 certification and examines the linkages between these motivations and self-reports of the effectiveness of major environmental management system (EMS) components. In a sample of 128 facilities in Beijing, Shanghai, and Guangzhou, the main drivers for certification were reported to be to ensure regulatory compliance, to enhance the firms reputation, and to improve environmental performance, in that order. Although motivation to achieve cost reductions were least emphasized, a broad range of motivations appears to be considered in the decision to seek certification to ISO 14001. Regression models linking these motivations to the EMS components suggests that internal motivations have an influence on most EMS components. One interesting exception to this, however, is that no significant relationship was observed between internal motivations and the promulgation of environmental objectives and targets. The relationships associated with external motivations for certification (i.e., those in response to customer and other stakeholder pressures) and EMS components, on the other hand, are weaker and tend to occur earlier in the process cycle. No significant relationships were found between motivations to reduce costs and perceptions of the effectiveness of EMS components. Overall, these findings suggest that ISO 14001, as currently being implemented in mainland China, may have a modestly useful role when used in combination with other policy mechanisms to move the Chinese economy toward more sustainable practices. It is asserted that the ISO standard could provide even greater benefits if Chinese registrars were more proactive in developing EMS in conjunction with even more rigorous third-party audits.Published online     

ISO 14001 registration: The process,the benefits,and the choice of registrar

This article introduces the concept of ISO 14001 registration, outlines related assessment processes, and reviews the drivers behind developing an ISO-14001-concordant environmental management system (EMS) and seeking third party registration of that EMS. It focuses on registration strategies for larger organizations and considerations in choosing a registrar, including: auditor qualifications, standards for the conduct of EMS audits, and some issues for audit and registration service providers. The authors conclude that it is beneficial to pursue an ISO-14001-concordant EMS and that the value of the system can be enhanced through registration. However, some thought should be given to choosing the appropriate registrar, in particular to their EMS and audit approaches and to the qualifications of their audit team. Service providers are also cautioned to remember that ISO 14001 is not the same as ISO 9000, and that the registrar's standard of care in the discharge of their work should reflect that. © 1998 John Wiley & Sons, Inc.     

Toward Environmental Management Systems in Australian Agriculture to Achieve Better Environmental Outcomes at the Catchment Scale

Environmental Management Systems (EMS) are being trialed for Australian agricultural industries as society becomes more concerned about agricultures environmental performance. EMS is a structured approach used by farm businesses to assess, monitor, and improve environmental performance. Use of EMS in conjunction with other policy tools (such as financial incentives and regulation) in agriculture could enhance management of both on-farm and off-farm environmental issues. Based on the international standard ISO14001, EMS was designed to be applied at the individual business level. However, governments in Australia are exploring its potential to be applied at a catchment scale, among other things, for the purpose of linking farm-level actions to catchment targets. In Australia, governments and catchment management bodies are using Integrated Catchment Management (ICM) as the framework to try to achieve environmental targets set out in catchment plans. In this article, we compare aspects of the EMS and ICM frameworks and comment on the potential of using EMS to achieve catchment-scale environmental outcomes. We conclude that EMS could be a useful policy tool to improve farm management and to contribute, in part, to better off-site outcomes at the catchment/landscape scale. Recommendations on the use of EMS at the catchment scale are discussed. These include using an educational approach for EMS delivery, linking the EMS process to catchment targets, and ensuring catchment targets are realistic and achievable.     

ISO 14001 EMS implementation planning

In 1996, the International Standards Organization (ISO) completed work on an environmental management system (EMS) standard: ISO 14001. The standard involves only five required elements, spans less than five pages, and upon initial review, appears relatively uncomplicated. As well, many of the ISO 14001 requirements may already be present in an organization's existing EMS. Nevertheless, the new standard presents a number of challenges to industry implementation. Whether an organization aims to start from scratch in developing an EMS under ISO 14001 or modify its existing EMS to meet the ISO challenge, implementation requires careful planning and analysis. This article provides a summary of the planning required to implement ISO 14001 at the facility level, including the initial planning effort and the identification of significant environmental impacts, objectives, and targets. The aim will be to eliminate some of the “hype” associated with ISO and provide some practical “how to” guidance for implementing the standard. The discussion begins with an overview of the initial planning effort and then turns to key planning requirements.     

Preparing for ISO 14000: An assessment guide

With ISO 14000 expected to roll out in 1996, have you begun to evaluate how well your current environmental management policy, programs, procedures, and objectives conform to published national and evolving global Environmental Management System (EMS) standards?. The ISO expects to adopt a final standard by mid-1996 which specifies requirements for an EMS (e.g., ISO 14001). In addition, national EMS standards have already been developed and published by organizations such as The British Standards Institute and, in the United States, NSF International, for example, BS 7750 and NSF 110–1995, respectively. This article shows how managers can begin assessing their operations to prepare for these new standards and improve overall environmental performance.     

Environmental information sharing: a means to support the legitimization of oyster farmers’ stewardship over water quality management in NSW,Australia

Oyster farmers depend on good water quality. Activities upstream from estuaries result in externalities that impact water quality. Over the last 10 years, oyster farmers have been developing estuary‐wide environmental management systems ( EMSs ) to tackle internal (i.e. industry‐related) and external (i.e. catchment) issues in N ew S outh W ales, A ustralia. Drawing on interview‐based research and document analyses, this paper shows that the process of creating an EMS for the oyster industry, as well as the creation of the EMS itself, resulted in legitimizing the industry's stewardship over the natural resource it depends on (water). For the oyster industry, this result was due to a change in the scale on which EMSs have been developed: instead of viewing issues at the individual business level, the systems expanded their viewpoint to the entire catchment, and included every oyster business in the estuary, as well as all other activities in the upper catchment. By providing a means of communicating internal efforts and with the support of local government bodies, EMSs provided a mechanism with which influence over upstream actors and activities could be exerted. We demonstrate this by using the ‘social‐ecological systems’ and ‘ ENCORE ’ frameworks, emphasizing the transitions that allowed for this change of scale to take place.     

Environmental management system vs green specifications: How do they complement each other in the construction industry?

Environmental Management System (EMS) has been one of the important tools for sustainable construction for around two decades. However, many issues concerning sustainable development have not been properly addressed, and there is a need for the introduction of green specifications to advance green performance in construction through contract management. This paper defines green specifications, identifies the reasons for adopting green specifications and highlights the environmental issues that may not be addressed by solely adopting EMS. It also presents the results of a recent survey of practitioners concerning their opinions towards green specifications and possible impacts arising from their adoption. From the results of the survey, a framework for developing green specifications is deemed valuable for the cities striving for sustainability. Interestingly, the level of acceptable changes brought about by green specifications as perceived by different industry stakeholders is found to be unrelated to whether they were from organizations implementing EMS or not.     

Progress with Implementing the Environmental Assessment Requirements of the Resource Management Act in New Zealand

The Resource Management Act 1991 (RMA) has introduced environmental impact assessment (EIA) into the operations of territorial authorities at the regional and district level in New Zealand. The system established by the RMA is not only devolved in administrative terms, it is also comprehensive in its application. This paper reports the findings of an interview-based survey of key personnel in selected regional and district councils, along with others from government departments, planning consultancies and law firms. The purpose is to assess the success of the councils in developing appropriate and workable procedures, and to identify the main problems likely to inhibit the development of an effective EIA system in New Zealand. Overall, the task of implementing the EIA requirements has been tackled positively by councils, but there are signs of major differences emerging in the EIA procedures they are developing. Key issues that need to be considered by councils include: the need for explanatory documentation for, and verbal advice to, resource consents applicants at the earliest stage possible; the lack of public involvement in the EIA activities and the need for council staff to encourage and facilitate such participation; and problems with ensuring the adequacy of EIA information in such a devolved and comprehensive EIA system.     

Evaluation of environmental management resources (ISO 14001) at civil engineering construction worksites: a case study of the community of Madrid

In recent years, significant advances have been made in business organization and management. The growing demands of clients as well as the globalization of world markets are among the many factors that have led to the establishment of systems of quality control and environmental management as a competitive strategy for businesses. When compared to other professional sectors, the construction sector has been slower to respond to environmental problems and to adopt Environmental Management Systems (EMS). In the world today the ISO 14001 standard is currently the main frame of reference used by construction companies to implement this type of management system. This article presents the results of a general study regarding the evaluation of the application of the ISO 14001 standard at civil engineering construction worksites in the Community of Madrid (Spain), specifically pertaining to requirement 4.4.1, Resources, roles, responsibilities, and authority. According to requirement 4.4.1, company executives should appoint people responsible for implementing the EMS and also specify their responsibilities and functions. The personnel designated for supervising environmental work should also have sufficient authority to establish and maintain the EMS. The results obtained were the following: - EMS supervisors did not generally possess adequate training and solid experience in construction work and in the environment. Furthermore, supervisors were usually forced to combine their environmental work with other tasks, which made their job even more difficult. - Generally speaking, supervisors were not given sufficient authority and autonomy because productivity at the construction site had priority over environmental management. This was due to the fact that the company management did not have a respectful attitude toward the environment, nor was the management actively involved in the establishment of the EMS. - Insufficient resources were allocated to the Environmental Management Unit. As a result, the application of EMSs in construction projects often appeared to be more of a formality, which was merely a way of maintaining the certification of the Environmental Management System. It was more a means of meeting the requirements for submitting a tender to contracting organisms rather than an indicator of any real commitment to improving the environmental performance of construction companies.

A Case-study of ISO 14001-based Environmental Management System Implementation in the People's Republic of China

The ISO 14001 implementation process among certified firms in China was examined by conducting a questionnaire survey distributed to all certified firms as of December 1998. Results showed that the ISO 14001-based environmental management system (EMS) has a significant effect on firms' daily environmental activities and performance. Recycling, natural resource consumption and released pollutants have been managed in a better way and, in some cases, pollutants have been reduced. The study showed that firms' main targets for adopting the system were to: enhance the firm's public image; enhance employees' environmental awareness; improve the EMS inside the firm; improve the environmental aspects and performance inside the firm; and improve relations with government offices and local citizens. ISO 1400-based EMS implementation showed that it is a promising tool for helping build a better partnership between three main stakeholders, government, local citizens and enterprises. The system has enabled firms to consider the role of the local people in a more effective way. For example, special consideration is given to involving local citizens in health and emergency preparedness during firms' daily environmental activities. Moreover, enhancing environmental awareness among the local citizens and giving more consideration to co-operation with other firms from the same industrial groups are reported by certified firms. Finally, there are strong demands for government support to build more reliable information systems, ISO 14001-related research, more incentives for eco-labelling and tax exemptions.

Integrated energy management strategy of powertrain and cooling system for PHEV

ABSTRACT

Energy management strategy (EMS) is crucial in improving the fuel economy of plug-in hybrid electric vehicle (PHEV). Existing studies on EMS mostly manage powertrain and cooling system separately which cannot get the minimum total energy consumption. This paper aims to propose a novel EMS for a new type of dual-motor planetary-coupled PHEV, which considers cooling power demand and effect of temperature on fuel economy. Temperature-modified engine model, lithium-ion battery model, two motors, and cooling system models are established. Firstly, the separated EMS (S-EMS) is designed which manages powertrain and cooling system separately. Sequentially, after the analysis of thermal characteristics of the powertrain and cooling system, the thermal-based EMS (T-EMS) is then proposed to manage two systems coordinately. In T-EMS, cooling power demand and the charging/discharging energy of motors are calculated as equivalent fuel consumption and integrated into the object function. Besides, a fuzzy controller is also established to deicide the fuel-electricity equivalent factor with consideration of the effect of temperature and state of charge on powertrain efficiency. Finally, the hardware-in-loop experiment is carried out to validate the real-time effect of EMS under the New European Driving Cycle. The result shows that cooling power demand and temperature can significantly affect the fuel economy of the vehicle. T-EMS shows better performance in fuel economy than S-EMS. The equivalent fuel consumption of the cooling system of T-EMS decreases by 27% compared with that of S-EMS. The total equivalent fuel consumption over the entire trip of PHEV using T-EMS is reduced by 9.7%.     

The impact of ISO 14001 on corporate environmental performance: a study of Swedish manufacturing firms

The debate concerning the environmental effectiveness of environmental management systems (EMS) based on ISO 14001 is still open and scholars have called for further studies that can explain the contrasting evidence in previous research. As a response, this study aims to contribute knowledge about the effects of ISO 14001-based EMS by presenting fact-based environmental data. The study focuses on changes in performance over a period of 12 years and includes both firms with an EMS (66 firms) and firms without one (50 firms). Consideration is given to the improvement efforts in the firms before EMS adoption making it possible to neutralize any selection effects where better environmental performance precedes ISO 14001 adoption. Analysis has been carried out using statistical methods for six different environmental areas. No statistically significant differences between certified and non-certified firms concerning the change in the rate of improvement could be found in any of the six areas. However, it can be suspected that EMS adoption has positive effects on energy use and waste production whereas the non-adopting firms seem to perform better concerning air emissions. These mixed results mirrors previous research, which is rather worrying considering the worldwide popularity of EMS based on ISO 14001 in industry.     

Are EMS environmentally effective? The link between environmental management systems and environmental performance in European companies

Based on the analysis of a large dataset on the environmental performance of European companies in five industrial sectors, this paper examines the question of whether the presence of an environmental management system (EMS) has a positive impact on the eco-efficiency of companies. It begins with a review of evidence about the link between EMS and environmental performance in business organisations, finding that, despite much research, there is still little quantitative evidence. The second part of the paper uses three independent statistical methods (simple correlations, Jaggi-Freedman indices and a ‘trend differences’ approach) to assess whether companies and production sites with EMS perform better than those without and whether performance improves after an EMS has been introduced. The paper shows that there is currently no evidence that EMS have a consistent and significant positive impact on environmental performance. Policy action based on the simple assumption that companies with an EMS perform better than those without therefore seems inappropriate.     

Expanding the benefits of environmental management systems through DFE

Industry's role in environmental protection is changing and growing. Increasing evidence shows that a corporation's understanding and response to environmental issues and concerns can have strategically important consequences for some kinds of businesses.¹ Focusing on concepts of prevention, industry has developed and struggled with a number of environmental approaches, all of which attempt to link the environment with common business practice. Industry has followed and in some cases embraced concepts and approaches like sustainable development, eco-efficiency, green manufacturing, pollution prevention, and extended product responsibility. A particularly timely and promising strategy to reduce the environmental impact of both manufacturing and product use while enhancing business success is the integration of environmental management systems (EMS) with design for the environment (DFE) efforts. A desirable relationship can and should exist between DFE and EMS. This relationship has not been well understood, but is crucial to fulfill the promise of each. In application, the institutionalization of DFE in an organization is difficult and tenuous at best. Some authors suggest that management issues block the implementation of DFE.² Others say that DFE has not been institutionalized to the extent that pollution prevention has.³ This article suggests that through an explicit connection between an EMS and DFE, DFE can extend the promise of EMS to reduce industry's environmental impact and produce business success, and it can do so in an ongoing way. The authors will show the importance of an EMS/DFE linkage, suggest company types that might benefit from investigating these approaches, and then review a series of DFE tool types.
