Shaping Climate Change Policy
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...
