The environmental aspect is now a significant element in polluting companies’ management choices. The laws defined by the establishment of standards and requirements to guarantee a minimally contaminated environment are applicable to these companies. These standards have encouraged companies to implement environmental management systems. According to these concepts, our research aimed at assessing the improvement in productivity of companies working in the industrial sector by adopting an environment management system. We evaluated productivity by defining and estimating the manufacturing function using a sample consisting of Thailand businesses, and then utilized the panel data to test its effect upon manufacturing companies’ productivity by adopting the environmental management system. The installation of an EMS and productivity have been favourable and significantly correlated

The interests of companies have increased to reduce or remove the waste produced during the manufacture, usage and/or disposal of the goods of the company. The necessity for such activities has been prioritised, while current research attempts to uncover the components which promote or dissuade such actions. With the advent of ISO 14001 corporate environmental management systems became the focus of attention (EMS). The basic premise is that such a system is crucial for the capacity of an enterprise to decrease waste and pollution and improve its overall performance concurrently. In this research, this assumption is assessed. Based on the data given by North American executives surveys, their behavior towards EMS and ISO 14001, the research evaluates the relative impacts of a formal but not certified EMS compared to a formal, certified system. The findings show firmly that companies with a formal EMS perceive well beyond pollution reduction and that the effect on many aspects of operating performance is critically favorable. The findings indicate that companies that have received EMS certification have a higher performance effect than companies that do not have their EMS certification. Moreover, experience with these systems has a larger effect on the selection and usage of environmental choices over time. These findings show the necessity to investigate deeper EMS, the environmental choices of a company and the direct and indirect connections between these systems and performance.

Environmental management accounting is a mechanism for determining and evaluating, and incorporating these cost and benefit in the day-to-day business decision making, the full spectrum of environmental costs of current production processes and the economic benefits of contamination prevention, or cleaner processes. In practice, the past 10 years have acquired significance from corporate accounting, which is the most prominent part of cost accounting. Limits were widely acknowledged of conventional financial and cost accounting techniques reflecting companies’ sustainability efforts and providing management with necessary information for sustainable business choices. Information on companies’ environmental performance may be somewhat accessible, but both domestic decision makers and those at the level of public authorities are seldom able to connect environmental information with economic variables and are essentially deprived of environmental cost information. Decision makers do thus not recognize the economic worth of natural resources as asset and the commercial and financial benefit of excellent environmental performance. Beyond ‘goodwill’ efforts, there are a number of market-based incentives for integration with decision making of environmental issues. This article provides an outline of environmental management methods and we evaluate environmental costs in terms of current economic crisis.
