Energy use associated with tourism has rarely been studied, despite a potentially considerable contribution to global or national energy demand and concomitant greenhouse gas emissions. In New Zealand, tourism constitutes an increasingly important economic sector that is supported by the Government to induce further economic growth. At the same time New Zealand is facing the challenge of reducing currently increasing fossil fuel combustion and carbon dioxide emissions. As a response, this study investigated the contribution tourism makes to energy use in New Zealand. In particular it has examined the role of the three main tourism subsectors (transport, accommodation, and attractions/activities), and different domestic and international 'tourist types'. Seven separate data analyses provided inputs for building a model based on 'tourist types' from which energy use in the New Zealand tourism sector could be estimated. Tourism was found to contribute at least 5.6% to national energy demand, which is larger than its 4.9% contribution to GDP in 2000. Transport, in particular domestic air and car travel, was identified as the dominant energy consumer. Within the accommodation sub-sector, hotels are the largest energy consumers, both in total and on a per visitor-night basis. Of the three sub-sectors, attractions and activities contribute least to energy use, however, activities such as scenic flights or boat cruises were recognised as being energy intensive. As a result of larger visitor volumes, domestic tourists contribute more to energy consumption than international tourists. Domestic and international tourists types differ in their energy consumption patterns, for example measured as energy use per travel day. Tourist types that rely on air travel are the most energy intensive ones, for example the domestic 'long air business' travellers or the international 'coach tourists'. The importance of international tourists' energy use will increase, given current growth rates. There are many options to decrease energy use of the tourism sector, with the most effective ones being within the energy intensive transport sub-sector. Increasing vehicle efficiencies and decreasing travel distances appear to be the most promising measures. This study argues that energy use depends largely on tourists' travel behaviour. Changing behaviour is possible but is postulated to be very difficult, and further research is needed to better understand tourists' motivations, expectations and decision-making. Only then, can strategies be developed and implemented to alter travel behaviours to better balance energy use, other environmental impacts and economic yield. Such a balance is a crucial consideration in the search for more sustainable forms of tourism.
