Firms in renewable energy industry are currently facing challenges to maintain competitiveness while keeping minimal environmental impacts. Responding to the above challenges, environmental management system (EMS) has becoming more popular within organizational policies, programs, and operating agendas. Especially, in the knowledge-intensive industry, the learning efforts of EMS can effectively improve technological development, managing efficiency, and firm performance at the same time. Then, the aim of this article is to examine the relationships among strategic objectives, the learning effects of EMS, and firm performance in the renewable energy industry. After practical investigation, it shows that the gaps between strategic objectives and firm performance can be narrowed if suitable management skills are applied for different EMS approaches.
