We examine why firms voluntary implement environmental management systems. We study both ISO 14001 and EMAS.
Using data for the Czech Republic, we find that the probability of an environmental management system implementation is increasing with the size of the organization. Next, more polluting corporations have higher probability of the implementation of the environmental management systems.
The probability of the environmental management systems adoption is influenced by the industry in which the company operates, too. On the other hand, we find no impact of firms' profitability, indebtedness and labour cost is identified.
