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:
* What would an ideal set of climate policy tools look like?
* How large are the economic and environmental costs of incomplete country or sector coverage of climate change mitigation policies? What are the pros and cons of policy tools to broaden that coverage, such as international sector-wide agreements or border-tax adjustments? What are the main challenges in incorporating a mechanism to reduce emissions from deforestation and forest degradation?
