Purpose – To investigate the potential future role of information delivery in terms of reducing transport-related emissions. The assumed response of travellers to information and the notions of content and context are provided, together with factors that can determine an individual's propensity to seek and engage with travel information.

Methodology/approach – A review of information use, the behavioural stages of change and context design is undertaken, incorporating a research case study in the use of framing.

Findings – Recent theoretical and empirical insights into behavioural change provide new insights into the role of information in reducing transport-related emissions. Traveller information offers many benefits to the user and could be influential in affecting travel behaviour change, although there are socio-psychological factors outside the control of information service designers that also need to be considered, such as the ‘stage of change’ people are at in relation to a change in behaviour.

Originality/value – The chapter examines how travel information could go beyond the provision of trip choice data and incorporate contextual elements to make it more effective. Concepts related to the Transtheoretical Model (stages of change) and the latest thinking in behavioural economics are discussed in relation to an increase in the likelihood of environmental travel alternatives being considered and chosen.

Due to the more pressing need, the majority of material in this book has dealt with mitigation; interventions to reduce emissions of greenhouse gases (IPCC, 2001) away from a scenario of ‘business as usual’. An early academic review on climate change mitigation and transport appeared in 2007 (Chapman, 2007), a year before the United Kingdom committed itself to the highly ambitious Climate Change Act 2008. The final act sought an ambitious 80% cut in greenhouse gas emissions by 2050. Although criticised in this book as being unrealistic, this is the level of intervention required if ‘dangerous’ climate change is to be avoided (defined as greater than 2°C rise in global temperatures). As Chapter 8 (a policy perspective) explains, such targets, however unrealistic, are informed by considerable input from expert opinion (e.g. Delphi studies) and require a detailed knowledge of current emissions as well as accurate predictions/scenarios of future emissions. For this reason, scenarios and the control of uncertainty were discussed in Chapter 2 towards the start of this book. Indeed, the commonly quoted ‘business as usual’ scenario is in itself too simplistic and highly improbable, not only due to mitigation measures imposed by governments, but also because of the future scarcity of oil which will force change in the medium term regardless. Backcasting is the key tool used to model the continuum of socio-economic scenarios which exist between ‘business as usual’ and the equally unlikely case of all targets being met. However, the science is inherently difficult and the end result is a wide range of permutations and storylines, largely dependent on mitigation. Early progress towards the 80% target has not been promising, but the decarbonisation of the transport sector is still seen as key in meeting the demands of the Climate Change Act 2008. There is a need to tackle the three primary culprits of greenhouse gas emissions in the transport sector: aviation, freight and car ownership (Chapman, 2007). This book has examined in detail how this could be achieved in all these sectors using a range of aspects relating to technological and behavioural change.

Climate change is recognised as one of the greatest challenges that contemporary global society faces. The IPCC (Intergovernmental Panel on Climate Change) Fourth Assessment Report (2007) states that it is ‘very likely’ that anthropogenic global warming will result in a temperature rise of between 1.8°C and 4°C by the end of the 21st century. Temperatures at the upper end of this range are considered ‘dangerous’, and the international community is focused on attempting to limit the increase to within 2°C (Meinshausen et al., 2009). Increasing global temperatures are just one consequence. The world will face an increasing level of unpredictable and extreme weather patterns, each with different, but in many cases, serious consequences for life on earth (IPCC, 2007).

Purpose – To examine the relationship between aviation and climate change, and the international dimensions of air transport.

Methodology/approach – A review of aviation's impacts on the global climate, mitigation strategies to reduce this impact, and the possible consequences of climate change for commercial aviation.

Findings – Although a range of mitigation measures have been developed and implemented to reduce aircraft emissions in the short term, with some environmental benefit, there is a real need for the aviation sector to identify the possible impacts of climate change on air travel operations, both to aircraft in flight and to operations at airports. A further challenge will be to devise adaptation plans that will address the vulnerabilities and thus ensure safe aviation-related operations.

Social implications – The climate change impacts of aviation will adversely affect society. In addition, some individuals may have to reduce or stop flying as a result of increased taxes and legislation implemented in response to climate change.

Originality/value of paper – There is a novel focus on the adaptation challenges for the aviation industry in response to climate change.
