The historic link between output (GDP) growth and employment has weakened. Since there is no quantitively verifiable economic theory to explain past growth, this unique book explores the fundamental relationship between thermodynamics (physical work) and economics. The authors take a realistic approach to explaining the relationship between technological progress, thermodynamic efficiency and economic growth. Their findings are a step toward the integration of neo-classical and evolutionary perspectives on endogenous economic growth, concluding in a fundamental explanation of endogenous growth that is both quantifiable and consistent with the laws of thermodynamics. For two centuries fossil and other sources of energy (work) have been replacing human and animal muscles. Now our civilization is truly addicted to fossil energy availability at ever low prices. Can increasing efficiency compensate for coming scarcity? This is the crucial question. The most important implication of this is that future economic growth is not guaranteed because the efficiency gains that have driven growth in the past may not continue in the future.Exploring the theory of growth with an emphasis on the role of energy, useful work and technological change, this book will be of great interest to academics and students focussing on growth theory, energy and ecological economics. It will also prove insightful to those concerned with policy making or responding to changes in policy related to the energy-growth nexus.

The conventional utility-based approach to microeconomics is now nearly a century old and although frequently criticised, it has yet to be replaced. On the Reappraisal of Microeconomics offers an alternative approach that overcomes most of the objections to orthodox theory, whilst offering some unique additional advantages.The authors present a new approach to non-equilibrium microeconomics that applies equally to production, trade and consumption, and that is also consistent with the laws of thermodynamics. This new theory is not limited to equilibrium or near-equilibrium conditions. The core of the theory is proof that, for each agent (firm or individual), there exists an unique function of goods and money (denoted Z) that can be interpreted as subjective wealth for an individual or the owners of a firm. Exchanges may occur only when both parties enjoy an increase in subjective wealth as a consequence. On average, this Z-function will increase over time if, and only if, the agent obeys a simple decision rule in all economic transactions: namely to 'avoid avoidable losses', or AAL, it being understood that some losses are unavoidable. Dynamic equations describing growth (or decline) can be derived simply by calculating time derivatives of a wealth function, without the need for constrained maximization of an integral of utility (or some surrogate) BM_1_over time. The Z-function also has a number of other interesting properties that can be used for multi-agent and multi-sectoral simulation models to explore a variety of economic situations that cannot be addressed so easily using conventional methods.This is a stimulating, provocative and highly original book that will appeal to informed academics, researchers and other professionals with an interest in the fundamentals of neoclassical economics and its applications to business, finance, growth and the environment.

Industrial ecology is coming of age and this superb book brings together leading scholars to present a state-of-the-art overviews of the subject.Each part of the book comprehensively covers the following issues in a systematic style: the goals and achievements of industrial ecology and the history of the field methodology, covering the main approaches to analysis and assessment economics and industrial ecology industrial ecology at the national/regional leve industrial ecology at the sectoral/materials level applications and policy implications. The authors are all experts at the cutting edge of the field and the bibliography alone will prove useful as a comprehensive guide to the literature. This outstanding handbook will be an indispensable reference for students and scholars working in environmental management, industrial ecology and environmental and ecological studies.

Industrial Ecology is perhaps the first serious attempt to go beyond general statements regarding the desirability of 'clean technology' and to assess realistically and quantitatively the range of practicable possibilities for reducing materials extraction, consumption and waste.This major new book examines strategic options for reducing wastes and pollution and increasing the productivity of materials. Using an industrial ecology perspective, the authors analyse thirteen generic cases of material, beginning with four families of metals (aluminium, chromium, copper and zinc), several families of chemicals (phosphates and fluorine; suphur-based, nitrogen-based and chlorine-based), silicon and several different types of waste. Opportunities for creating 'industrial ecosystems' by deliberate design are discussed as well as the use of low-value by-products as feed stocks for useful products. In addition to surveying the technological possibilities, the authors also consider the public interest, institutional barriers and the range of possible alternatives that might be applicable. Environmental scientists, economists, practitioners and policy makers will welcome Industrial Ecology's integrated approach and the emphasis which it places on resource productivity, materials cycle optimization and waste minimization.

This companion to Accounting for Resources, 1 tracks the life cycle of specific elements, such as chlorine and heavy metals, in order to estimate the generation and dissipative losses of material wastes.The book begins with a succinct review of the life-cycle analysis methodology and evaluates some of its weaknesses in estimating the generation of waste. The authors propose a new quantitative measure of the potential for environmental harm of waste materials. They include case studies to add weight to their proposal. Four horizontal life-cycle case studies are included; one for chlorine and chlorine chemicals; one for mercury; one for arsenic and cadmium; and the other for copper, lead and zinc. The book also includes a longitudinal study of heavy metals use and dissipation, during the period 1880-1980 with reference to the Hudson-Raritan basin. The book concludes with an overview, including some recommendations for future research and for policy changes with respect to governmental statistical data collection and organization.

This innovative book presents new research on the increasingly important need to account for the use of resources, and the dispersion of waste materials. It considers resource accounting both at the process level and at the materials level, and in addition offers policy suggestions for waste and resource accounting.The book opens with an introduction to industrial metabolism and its various implications. It then goes on to examine resource accounting at the national and sectoral level, through the systematic application of the mass-balance principle to estimate materials losses at different stages of the production process. It then examines one cluster of industries (related to chlorine) in greater detail. At the process level the use of chemical process simulation software in the estimation of waste emissions is examined, specifically focusing on cases where emissions data is unavailable or unreliable. Finally it introduces, for the first time, a common single measure for evaluating and comparing process or sectoral resource and waste flows between time periods, between sectors and between regions and nations. This measure is known as exergy, and although not new in itself, it has never before been used systematically for these purposes. In conclusion the author summarizes the main problems of resource and waste accounting and offers some policy recommendations for the implementation of accounting for resources.Accounting for Resources, 1 will be welcomed by environmental managers and scientists, economists, practitioners and government policymakers.
