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 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.

This book shows how city and metropolitan regional governments working in tandem with national governments can change the way we think about responding to climate change.

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is scarce, however, on the most effective policy mix and the role of mitigation tools and goals in the overall policy framework.

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.

"Cognisant of the many facets of climate change, this report looks through the lens of economics, that is, the social science that measures the economic impact of climate change and the costs and benefits of trying to mitigate it and adapt to it. From an investment perspective, issues for study include the balance between investment in mitigating greenhouse-gas emissions and adaptation to climate change; the urgency and timing of investing in both; obstacles to investment; and policies to remove them and make investment profitable. From a growth perspective, issues of interest include the link between climate action and economic growth; the short-term and the long-term dimensions of this link; and the importance of innovation as an interface between climate action and economic growth. One of the key messages from this report is that there is unexploited scope for making Europe's climate action more efficient, growth-friendly, and in tune with fiscal constraints."--publisher's description.

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.
