Although Taiwan arguably needs civil and official collaboration on environmental protection, the implementation of an efficient system of environmental regulations has often been hindered by the many actors involved in the process of environmental governance (state, economic actors, civil society, media), whose interests are divergent. Consequently, there is no uniform, homogeneous authority for environmental governance but rather a variety of official and less official agents of authority whose interests and powers overlap and compete. In this paper we will introduce a case study dealing with the controversy surrounding the construction of an alternative road connecting Danshui (淡水) with Taibei City (namely, the Danshui North Shore Road Project, 淡北道路, Danbei daolu) to elucidate what the key influences are that govern environmental power dynamics between different agents with conflicting (or, sometimes, colluding) interests and how these multiple levels of interaction are negotiated by the various players. Our hypothesis holds that although environmental policies are, for the most part, mandated from the top, at the local level their implementation can be bypassed, altered or stalled by these various agents.
