The full effects of decisions made today about many environmental policies -including climate change and nuclear waste- will not be felt for many years. For issues with long-term ramifications, analysts often employ discount rates to compare present and future costs and benefits. This is reasonable, and discounting has become a procedure that raises few objections. But are the methods appropriate for measuring costs and benefits for decisions that will have impacts 20 to 30 years from now the right ones to employ for a future that lies 200 to 300 years in the future? This landmark book argues that methods reasonable for measuring gains and losses for a generation into the future may not be appropriate when applied to a longer span of time. Paul Portney and John Weyant have assembled some of the world's foremost economists to reconsider the purpose, ethical implications, and application of discounting in light of recent research and current policy concerns. These experts note reasons why conventional calculations involved in discounting are undermined when considering costs and benefits in the distant future, including uncertainty about the values and preferences of future generations, and uncertainties about available technologies. Rather than simply disassemble current methodologies, the contributors examine innovations that will make discounting a more compelling tool for policy choices that influence the distant future. They discuss the combination of a high shout-term with a low long-term diescount rate, explore discounting according to more than one set of anticipated preferences for the future, and outline alternatives involving simultaneous consideration of valuation, discounting and political acceptability.
Originally published in 1984, this book develops a quantitative model designed for use in the evaluation of the relative merits of alternative energy R&D programmes. It is used to compare the merits of major energy-technology R&D programmes during the 1970s in the USA: Liquid-metal fast breeder reactors, synthetic fuels derived from coal and oil shale and improved efficiency in end-use technologies. The benefits/disadvantages are analyzed in terms of economics, security and the environment. Although published some years ago, the economic benefit assessed is in terms of the impact that commercialization of a particular energy-technology would have on the total 60 year cost of the US energy supply system. The security benefit is measured in terms of the reduction of crude oil imports and the environmental factors are measured here by the total tonnage of coal and oil shale that is extracted each year. All of these issues continue to be relevant today.
Is ?conservative environmentalism? an oxymoron? Is more environmental regulation good for business? The Greening of Conservative America contends that the adherents to any well-considered conservative political philosophy should, on first principles, support pro-conservation, pro-environment policies. Furthermore, and pragmatically, Bliese demonstrates with repeated examples how environmental protection policies actually benefit business by stimulating greater efficiency and innovation and by spurring the creation of green products and services for new markets around the globe. These ideas are applied in chapters on specific environmental issues, including pollution, global warming, biodiversity, public-land management, and sustainability. The book concludes with criticisms of ?free-market environmentalism? and calls conservatives back to their root principles on matters of the environment. Concerned citizens of any political persuasion will find much in this book to inform their views on public debates over environmental issues and policies.
