This chapter explores the ways in which uncertainty arises as a recurrent feature of the policy life-cycle. It discusses the state of the knowledge and identifies research needs in each of these areas. Acknowledging these real world conditions destabilizes the usual means by which we model, interpret, and portray the move from scientific understanding to policy construction. The chapter describes the different intersections that focus on the analyses of the local design and implementation of climate change policies. It argues that the subnational initiatives, like California's AB 32 and SB 375, provide an unrivaled opportunity to significantly improve our understanding of how uncertainty is identified and managed in local governance and community responses to legislatively directed changes. It also argues that uncertainty is inherently embedded in the communication and interaction between science and the policy process, between levels of government and between local implemented and their communities.

Reflecting the dynamic relationships between socio-technical behaviour and change, this book presents leading research on the transition process needed to achieve more sustainable transport systems. Focusing on making transition happen, this volume looks at various aspects and factors that are involved in the transition process and their implications for transport policy-making. The concept of Transition Management and how it can be applied to the transport sector is considered in detail, and forms the focus of the first part of the volume. The rest of the book is organised according to the three themes of transport energy use and emissions, the role of information in policy-making, and the evaluation of transport policy. This volume brings together scholars involved in research from various disciplines and countries to discuss the relationships between policy instruments, individual behaviour, institutional practices and the transition towards more sustainable transport systems.
