This title contains 25 invited chapters that present the most current thinking on the environmental mechanisms contributing to global climate change and explore scientifically grounded steps to reduce the buildup of greenhouse gases in the atmosphere.
This open access book analyzes and seeks to consolidate the use of robust quantitative tools and qualitative methods for the design and assessment of energy and climate policies. In particular, it examines energy and climate policy performance and associated risks, as well as public acceptance and portfolio analysis in climate policy, and presents methods for evaluating the costs and benefits of flexible policy implementation as well as new framings for business and market actors. In turn, it discusses the development of alternative policy pathways and the identification of optimal switching points, drawing on concrete examples to do so. Lastly, it discusses climate change mitigation policies’ implications for the agricultural, food, building, transportation, service and manufacturing sectors.
Models are fundamental for estimating the possible costs and effectiveness of different policies for reducing greenhouse gas (GHG) emissions. There is a wide array of models to perform such analysis, differing in the level of technological detail, treatment of technological progress, spatial and sector details, and representation of the interaction of the energy sector to the overall economy and environment. These differences impact model results, including cost estimates. More fundamentally, these models differ as to how they represent fundamental processes that have a large impact on policy analysis-such as how different models represent technological learning and cost reductions that come through increasing production volumes, or how different models represent baseline conditions. Reliable estimates of the costs and potential impacts on the United States economy of various emissions reduction and other mitigation strategies are critical to the development of the federal climate change research and development portfolio. At the request of the U.S. Department of Energy (DOE), the National Academies organized a workshop, summarized in this volume, to consider some of these types of modeling issues.
To understand the impacts of support programs on global emissions, this paper considers the impacts of domestic subsidies, price distortions at the border, and investments in emission-reducing technologies on global greenhouse gas (GHG) emissions from agriculture. In a step towards a full evaluation of the impacts, it uses a counterfactual global model scenario showing how much emissions from agricultural production would change if agricultural support were abolished worldwide. The analysis indicates that, without subsidies paid directly to farmers, output of some emission-intensive activities and agricultural emissions would be smaller. Without agricultural trade protection, however, emissions would be higher. This is partly because protection reduces global demand more than it increases global agricultural supply, and partly because some countries that currently tax agriculture have high emission intensities. Policies that directly reduce emission intensities yield much larger reductions in emissions than those that reduce emission intensities by increasing overall productivity because overall productivity growth creates a rebound effect by reducing product prices and expanding output. A key challenge is designing policy reforms that effectively reduce emissions without jeopardizing other key goals such as improving nutrition and reducing poverty. While the scenario analysis in this paper does not propose any particular policy reform, it does provide an important building block towards a full understanding the impacts of repurposed agricultural support measures on mitigation of greenhouse gas emissions and adaptation to climate change. That full analysis is being undertaken in subsequent work, which will also take account of land-use change and alternative forms of agricultural policy support to align objectives of food security, farmers’ income security, production efficiency and resilience, and environmental protection.
This report reviews trends and progress on climate change mitigation policies in 34 OECD countries and 10 partner economies (Brazil, China, Colombia, Costa Rica, Indonesia, India, Latvia, Lithuania, the Russian Federation and South Africa), as well as in the European Union.
We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.
Ecological complexity and diverse ecosystems give Central and West Asia rich natural resources and hydrocarbon reserves. Countries in this region are exposed to climate change risks, and there is growing recognition that their carbon-intensive economies necessitate greenhouse gas mitigation. This report assesses the costs, benefits, and investment opportunities for greenhouse gas reduction in the energy and transport sectors of Azerbaijan, Kazakhstan, and Uzbekistan, and discusses indirect benefits of such reduction to human health and energy security. It gives policymakers, practitioners, and academics an overview of policy measures and technologies available for emission reduction, as well as scenarios of future emission trajectories in the three countries.
This Congressional Budget Office (CBO) study--prepared at the request of the Ranking Member of the House Committee on Science--presents an overview of issues related to climate change, focusing primarily on its economic aspects. The study draws from numerous published sources to summarize the current state of climate science and provide a conceptual framework for addressing climate change as an economic problem. It also examines public policy options and discusses the potential complications and benefits of international coordination. In keeping with CBO's mandate to provide impartial analysis, the study makes no recommendations.
Against the background of a projected doubling of world greenhouse gas emissions by mid-century, this book explores feasible ways to abate them at least cost.
This book describes the principles of integrated assessment models (IAM) for climate change economics and introduces various computable models for different development mechanisms under climate change governance. The authors present several new models they have constructed based on the RICE framework, specifically the MRICES((multi-factor RICE)) and EMRICES models, which incorporate global economic interactions into the RICE framework, and the CINCIA model, which describes technological advances and industrial structure evolution, introducing the mechanism of evolutionary economics. The models discussed in the book help governments and policy-makers tackle climate change and take positive measures on climate governance as well as promote economic and social development to narrow the gaps between countries.
