Sustainable Automobile Transport

Shaping Climate Change Policy

Lisa Ryan and Hal Turton

Transport, and in particular road transport, represents a significant global threat to long-term sustainable development, and is one of the fastest-growing consumers of final energy and sources of greenhouse gas emissions. In this book, long-term energy–economy–environment scenarios are used to identify the key technological developments required to address the challenges passenger car transport poses to climate change mitigation and energy security. It also considers possible targets for policy support and examines some of the elements that contribute to the significant levels of uncertainty – particularly social and political conditions. The book then builds on this long-term scenario analysis with a broad review of recent empirical examples of relevant policy implementation to identify near-term options for the passenger transportation sector which may promote a shift towards a more sustainable transport system over the longer term.

Chapter 11: Future Technology Developments in Transport

Lisa Ryan and Hal Turton


Future technology choice is one of the important elements in the realization of a sustainable transport system over the long term. However, there are a number of challenges to overcome before the advantages of new and emerging technologies can be fully exploited. To address these challenges policymakers are utilizing a range of measures, described in Part III of this book, that aim to shift today’s transport systems towards sustainability. The question of how and in what form sustainable development may ultimately manifest or materialize in the transport sector was explored in Chapter 5, where we described one configuration of a possible future longterm global sustainable transport system. From this scenario we can extract a number of key developments in vehicle and fuel production technologies needed for the emergence of a sustainable transport system. The analysis in Chapter 6 helped show which of the developments in the sustainable transport scenario presented in Chapter 5 are unlikely to emerge without some form of public support or intervention. Sustainable development has been defined in Chapter 1 to include sustainable goals of economic growth, increasing equity between world regions, a reduction of global environmental stress, in particular carbon emissions, and maintaining secure energy supplies. The sustainable development scenario from Chapter 5 provides a dynamic picture of the technologies that may be required to shape sustainable transport. It illustrates the potential to achieve through technical innovation close to zero greenhouse gas emissions in 2100. On this basis, this chapter summarizes the main long-term...
