ABSTRACT
Climate change has been described as the greatest environmental challenge of our time, not only for mankind (UN, 2011), but also for tourism (OECD-UNEP, 2011). Severe impacts of climate change, generally linked to exceeding 2°C global temperature rise, can only be prevented to some extent by drastically reducing the use of fossil fuels and thereby greenhouse gas (GHG) emissions within the next few decades. In this respect, an 80–95 per cent reduction of CO2 emissions by 2050 compared to 1990/2000 levels is recognised as the minimum required effort (Allison et al, 2009; Rogelj et al., 2011). Even with a full implementation of these goals, an increase above 2°C is not unlikely (World Bank, 2012).
