The Economics of Climate Change Mitigation

Policies and Options for Global Action beyond 2012

image of The Economics of Climate Change Mitigation

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. Through quantitative analysis, it addresses key climate policy issues including: an ideal set of climate policy tools; the size of the economic and environmental costs of incomplete country or sector coverage of climate change mitigation policies;  how to concretely develop a global carbon market; the case for, and what can we reasonably expect from, R&D and technology support policies; and  the incentives for major emitting countries to join a climate change mitigation agreement.

Greenhouse Gas Emissions and the Impact of Climate Change

This chapter describes past trends in greenhouse gas emissions, and future projections. It presents the potential consequences of climate change when no action is taken, and discusses the associated risks and uncertainties. The chapter assesses four different scenarios for stabilising greenhouse gas concentrations, and examines how differences in the stabilisation target, peaking year and level of overshooting of the target affect the costs of action. These scenarios all assume that mitigation policies are cost-effective, i.e. that all carbon emission sources can be priced globally, to provide a benchmark for more realistic scenarios examined in later chapters.
