Horizontal and Vertical Integration of Sustainability into Policymaking, Planning and Implementation of Renewable Energy Projects—The New Zealand Model

Abstract

While sustainable development is now widely accepted as an interna- tional normative principle guiding human interaction with the natural environment, it can be little more than an aspirational platitude unless incorporated in a practical and enforceable way in domestic regulation and processes. This paper addresses the vertical and horizontal integration of sustainability into policy-making, planning and decision-making with a particular focus on renewable energy developments. New Zealand is unique in the way it has incorporated the principle of sustainability as an enforceable concept in domestic legislation. The approach incorporates a hierarchical model with an environmental sustainability objective at the apex. This influences policy-making and “macro-planning” at the national and regional levels, which in turn influences lower level planning and operational decision-making. The system is integrated both vertically between different levels of government (central, regional and municipal), and horizontally between central and local government and resource management agencies, corporations, public interest groups and indi- viduals. The system is a result of an exhaustive administrative and law reform process in the late 1980s-early 1990s that restructured central and local government agencies, and implemented major legislative reform. The underlying conceptual model may be described as “integrated environmental management” (IEM). The system has now been in place for 25 years, and has been continually amended and refined in that time. It provides a useful model of a considered and coherent approach that facilitates sustainable management of the environment and natural resource development, including encouraging greater uptake of renewable energy.
