Analysing International Tourist Flows to Estimate Energy Use Associated with Air Travel

Abstract

Tourism is a major global industry and air travel is an increasingly vital component of international tourism. This paper examines the neglected relationship between tourism and aviation with regard to global environmental impacts, including energy use and greenhouse gas emissions. Based on visitor arrival data collected by Statistics New Zealand, it estimates a total energy use of 27.8 PJ resulting from international passenger air travel to New Zealand, which would increase national energy use by 6% if international air travel were included in national inventories. This energy use translates into additional carbon dioxide emissions of 1.9 million tonnes. These estimates are discussed in terms of a tourist's 'energy bill', national and international climate change policies, and with regard to the concept of sustainable tourism development.

Resilience and sustainability: a complementary relationship? Towards a practical conceptual model for the sustainability–resilience nexus in tourism

“…New Zealand tourism faces some significant challenges in meeting the test for sustainability (Becken, 2002(Becken, , 2008b given its distance from mass markets. Most NBT attractions are peripheral to New Zealand's main centres, requiring additional air and road transport once visitors arrive.…”

Tourists' Perception of International Air Travel's Impact on the Global Climate and Potential Climate Change Policies

“…The study is set in New Zealand; a destination that in terms of international tourism is totally dependent on international air services (Becken, 2002). New Zealand is often perceived as a 'clean and green' destination, and tourists here have been found to be open to discussions on the environmental impacts of their travel (Fairweather et al, 2005).…”

Going Green: Motivations for Environmental Commitment in the Airline Industry. A Case Study of Scandinavian Airlines

“…(Eckersley, 1995a: 1) Air travel is one of the fastest growing, most dynamic and volatile sectors in tourism. It is also associated with some of the most significant environmental impacts of tourism including high levels of fuel consumption, noise, air pollution and waste production (Air Transport Action Group, 2002;Becken, 2002;Clancy, 2001;Middleton & Hawkins, 1999;Penner et al, 1999). Tourists are using air travel more frequently to get to and from their destination.…”
