Stabilization of atmospheric concentrations of greenhouse gases to safe levels will require, at least in the longer term, some kind of technological revolution. This, in turn, can only be achieved through investments in the research, development and demonstration (RD&D) of carbon-free energy technologies. Innovation under Uncertainty presents original research and insights on the uncertain future of carbon-free energy technologies. The authors, by means of structured interviews with technology experts, portray a probabilistic landscape of future technologies' costs, potentials and limits to diffusion.This book collates the results of interviews with more than a hundred and twenty energy technology experts on a wide range of topics, from the impact of public European RD&D investment on the future cost of different low-carbon energy technologies to issues such as technological and diffusion barriers. The results offer important and concrete insights and recommendations concerning the potential role for public expenditure in innovation to bring clean generation technologies to the market. This unprecedented collection of qualitative and quantitative estimates will be invaluable to academics and policy makers drafting future energy policies, and integrated assessment and energy modelers characterizing the future development of different technological options.

This book presents provides a rigorous yet accessible treatment of the main topics in climate change policy using a large body of research generated using WITCH (World Induced Technical Change Hybrid), an innovative and path-breaking integrated assessment model.The authors give a particular emphasis to the analysis of technological change necessary to build low-carbon economies. The WITCH model can track all of the actions which impact the level of mitigation - such as R&D expenditures, investments in carbon-free technologies and adaptation, purchases of emission permits, or expenditures for carbon taxes - thus allowing for the evaluation of equilibrium responses stimulated by different climate policy tools. The chapters examine various questions to explore the future of climate change policy. Why is it so hard to achieve a global agreement that paves the way to widespread reductions of carbon dioxide and other greenhouse gas emissions? What are the technologies that would deliver clean energy without harming economic growth? And finally, how does uncertainty about future policies and future technologies affect choices in the present? This innovative book will appeal to researchers, policy makers and academics interested in climate change policy. Contributors: V. Bosetti, C. Carraro, E. De Cian, T. Longden, E. Massetti, L.

This insightful book explores the issue of sustainable development in its more operative and applied sense. Although a great deal of research has addressed potential interpretations and definitions of sustainable development, much of this work is too abstract to offer policy-makers and researchers the feasible and effective guidelines they require. This book redresses the balance. The authors highlight how various indicators and aggregate measures can be included in models that are used for decision-making support and sustainability assessment. They also demonstrate the importance of identifying practical means to assess whether policy proposals, specific decisions or targeted scenarios are sustainable. With discussions of basic concepts relevant to understanding applied sustainability analysis, such as definitions of costs and revenue recycling, this book provides policy-makers, researchers and graduate students with feasible and effective principles for measuring sustainable development.

Deforestation and forest degradation have long been recognized as environmental problems, with concerns over conservation of natural habitats and biological diversity capturing both scientific and public attention. More recently, the debate over tropical forest conservation has radically shifted to the approximately fifteen percent of global greenhouse gas emissions that are caused by deforestation and forest degradation, and to the potential synergies from integrating forest management with climate change policies. The goal of this book is to shed light on some of the major concerns, issues and challenges related to the inclusion of forest carbon in international climate policies, as well as to illustrate some of the potential solutions and paths forward. In addition, the book describes the status of REDD (Reducing Emissions from Deforestation and forest Degradation) in international climate policy negotiations, providing an historical perspective and highlighting the current positions of key international players that will frame the future debate at the national, regional and international level. This study will find a broad readership among researchers and policymakers interested in the environment, climate change and resource management.
