The New Zealand Government has developed and revised different climate change policies (GCCPs) over the last nine years in order to meet its Kyoto obligations and address the challenges of climate change. The key GCCPs are the carbon tax proposed in 2002 but cancelled in 2005; the Projects to Reduce Emissions (PRE) scheme during 2003-2004; and an emissions trading scheme (ETS) announced in 2007, legislated in 2008 and then modified in 2009. These GCCP changes are likely to impose significant costs and additional volatilities and pressures on electricity generators because their production activities are emissions-intensive. Consequently generators have been the direct targets of various GCCPs.  This study addresses the following research question: “What are the management control system (MCS) implications arising from strategy choices New Zealand electricity generators make in managing economic volatility and societal pressures resulting from a prolonged period of GCCP change?”. In answering this question, the study adopts a multiple-theory research framework that builds on insights from prior literature and the theoretical perspectives of transactional cost economics, institutional theory and resource-based theory. This study uses a multiple-case study that analyses interviews and 10-years of documentary data related to five major generators within the New Zealand electricity industry over five periods from 2000 to 2009.  The results suggest that GCCP changes impose external economic volatilities and societal pressures on the generators and affect their costs, market competitiveness, and social legitimacy. The diversity of internal characteristics and capabilities of the generators are found to moderate their relative degree of exposure to these external volatilities and pressures. Ten GCCP-related environmental strategies were formulated and implemented by the generators, with different levels of proactiveness (i.e. scope and timing), varying top management emphasis, as well as distinct underlying objectives. These strategy choices had significant implications for organisational MCS. In response, a wide range of controls and control systems were adopted. These can be classified into eight MCS component types and three MCS component groups, each of which supported one or more environmental strategies. Managers varied the degree of use of these MCS component types and groups to match the level of strategy proactiveness and top management emphasis pursued within each period. Additionally, the organisational MCS was underlined by three main objectives (cost control, competitiveness, and legitimacy) which in turn were driven by each generator’s primary strategy objectives and GCCP-related external exposure.  This study addresses a number of gaps in the academic literature and demonstrates the merits of a multiple-theoretical framework in examining GCCP-related strategy and MCS changes. The results also have significant implications for managers and practitioners when planning organisational adaptation to a carbon-constrained economy. Further, the study provides a useful basis for regulators and policy-makers in making the appropriate assessment and providing advice to improve the GCCPs’ environmental and economic outcomes.
