In the policy-making process concerning energy and environmental issues, cooperation between government and firms is a means to create a more efficient energy and environmental policy. Intermediary organizations can play an important role in this policy-making process. Aim of this study is to get insight into the role of one specific intermediary organization: the industry association. In this paper, we focus on the Dutch paper and board industry. Important policy themes for this industry are waste water, waste, and energy efficiency. We distinguished four types of governmental policy instruments: top-down regulation, interactive regulation, negative economic instruments, and positive economic instruments. We analyzed the role of the industry association in the policy-making process for all of these four instruments. The results clearly show different (relative) roles of the industry association in different steps of the policy-making processes and for different types of instruments.
