Environmental Auditing and the Role of the Accountancy Profession: A Literature Review 总被引:3,自引:0,他引:3
This review of the literature on environmental auditing and the potential role of accountants distinguishes between compliance audits and audits of the environmental management system. After an extensive introduction to the concept, this review focuses on the similarities and differences between an environmental audit and a financial statement audit. The general approach to both types of audits is similar, except that environmental audits are largely unregulated. Both audits place an emphasis on the evaluation of control systems, which is an argument in favor of external auditors playing a role in environmental audits. Another argument for including external accountants is their code of ethics. However, these professionals seem to be reluctant to enter the field of environmental auditing. It is argued that this reluctance is because of a lack of generally accepted principles for conducting environmental audits. If external accountants are engaged in environmental auditing, they should be part of multidisciplinary teams that also include scientists and engineers to avoid a too strong focus on procedures. Rather than treating these audits as totally different, it is proposed that there be a move towards integrated, or even universal, audits. 相似文献

Environmental auditing: Theory and applications 总被引:3,自引:0,他引:3
The environmental audit has become a regular part of corporate environmental management in Canada and is also gaining recognition
in the public sector. A 1991 survey of 75 private sector companies across Canada revealed that 76% (57/75) had established
environmental auditing programs. A similar survey of 19 federal, provincial, and municipal government departments revealed
that 11% (2/19) had established such programs. The information gained from environmental audits can be used to facilitate
and enhance environmental management from the single facility level to the national and international levels. This paper is
divided into two sections: section one examines environmental audits at the facility/company level and discusses environmental
audit characteristics, trends, and driving forces not commonly found in the available literature. Important conclusions are:
that wherever possible, an action plan to correct the identified problems should be an integral part of an audit, and therefore
there should be a close working relationship between auditors, managers, and employees, and that the first audits will generally
be more difficult, time consuming, and expensive than subsequent audits. Section two looks at environmental audits in the
broader context and discusses the relationship between environmental audits and three other environmental information gathering/analysis
tools: environmental impact assessments, state of the environment reports, and new systems of national accounts. The argument
is made that the information collected by environmental audits and environmental impact assessments at the facility/company
level can be used as the bases for regional and national state of the environment reports and new systems of national accounts. 相似文献

In 1995 the authors spent a considerable amount of time conducting audits and audit training classes all over the world. In rolling out Colgate-Palmolive's reengineered environmental audit program, they coupled a two-day training program with a three-day audit. Whether in Asia-Pacific, South America, Europe, or the United States, auditors, especially those newly trained, always seemed to fall into the same traps time and again. In order to facilitate the learning process, the authors prepared a list of 20 tips to use at the beginning and end of all training programs and audits. In this article, the authors share the 20 “golden rules” to help all auditors improve the quality of their audits. 相似文献

While some companies have established scoring systems within their audit programs, few utilize the full potential for measurement of the information gathered and subsequently produced from audits. In this article, the use of a computerized tracking system developed and used by Browning-Ferris Industries is discussed, along with a data report that details the completion of audit items and helps assure that action plans resulting from environmental audits are completed. This and other summary reports from the computer tracking system have provided meaningful measures of individual facilities' and overall company performance. 相似文献
