PURPOSE The purpose of this paper is to examine whether the decline in environmental quality in India, China and Brazil is due to release of toxic gases which is an effect of high energy consumption? If so, the increase in energy consumption is due to rapid economic growth led by industrialization? Also examined is what effect does excessive economic growth rates have on energy consumption levels in these countries.

In recent years, the literature in the field of general equilibrium modeling has increased. For long-term energy projections, general equilibrium models are more adequate than standard econometrics in evaluating alternative economic policies in a theoretically consistent framework. The well-known structure and economic mechanism of those models makes it easier to analyze structural changes of prices and quantities demanded or supplied for a given data set of an economy, national income accounts figures, and trade balance effects. The dynamic formulation of these models via investment decisions and capital formation also enables an intertemporal interpretation of structural adjustment and growth processes.

Economists have confined the concept of 'sustainability' to intertemporal distributional equity. We propose a broader definition, combining dynamic efficiency and intergenerational equity, and relate it to two concepts from neoclassical economics: potential Pareto-improvements and inter-personal compensation.

Domestic cookstoves in rural India have long been targeted by development programs dedicated to solving a diverse range of problems from deforestation and indoor air pollution to global warming and rural market inefficiencies. Theories on how technologies are mobilized in these design and diffusion innovation projects and what this presages for development outcomes can be improved by explicitly detailing the composition and structure of program governance frameworks. I develop a ‘dual adoption analytic framework’ to interrogate two technology innovation programs in Western India. This framework underscores the collaborative nature of technology mobilizations and, more specifically, how power is distributed across partnerships at different stages of the development process. Local partners are shown to function as influential mediating agents operating between extrinsic agencies and targeted village groups. They reinforce funding agency planning commitments while also activating economic contingencies and generating alternative development pathways. I also reveal how the structure of technology innovation projects—as either administratively heavy handed or committed to free market principles—influences intermediary behavior, intrapartnership structures of control and, ultimately, development outcomes for targeted artisan communities and households.

In urban America, land development and residential real estate have passed through a number of different phases during the post-WWII era. In contemporary discourse on urban sustainability, attention is often expressed in terms of intensity of land development, lot sizes, and square-footage of housing units. In this paper, we reconstruct the land development trajectory of a rapidly growing southern city in the United States and assess whether this trajectory has experienced any reversal in the face of socio-economic transformations that have occurred over the past decade or so. Starting with current land and real estate property records, we reconstitute the urban map of Charlotte using World War II as a starting point. Results highlight a decline in the average single family lot size over the past decade, while the average home size has consistently grown, suggesting that the city of Charlotte and its county have witnessed a densification trend along a path towards greater land development. This analysis both helps situate Charlotte with respect to other U.S. urban regions, and provides support for potential land-use policies, especially densification, when a balance between urban development, environment preservation, energy savings, and the achievement of quality of life for current and future generations are concerned.

This paper articulates and applies frameworks for examining whether consumption is excessive. We consider two criteria for the possible excessiveness (or insufficiency) of current consumption. One is an intertemporal utility-maximization criterion: actual current consumption is deemed excessive if it is higher than the level of current consumption on the consumption path that maximizes the present discounted value of utility. The other is a sustainability criterion, which requires that current consumption be consistent with non-declining living standards over time. We extend previous theoretical approaches by offering a formula for the sustainability criterion that accounts for population growth and technological change. In applying this formula, we find that some poor regions of the world are failing to meet the sustainability criterion: in these regions, genuine wealth per capita is falling as investments in human and manufactured capital are not sufficient to offset the depletion of natural capital.

This article examines and compares efforts to reduce energy subsidies in China, India and Russia. Despite dissimilarities in forms of governance, these three states have followed surprisingly similar patterns in reducing energy subsidies, characterised by two steps forward, one step back. Non-democratic governments and energy importers might be expected to be more likely to halt subsidies. In fact, the degree of democracy and status as net energy exporters or importers does not seem to significantly affect these countries’ capacity to reduce subsidies, as far as can be judged from the data in this article. Politicians in all three fear that taking unpopular decisions may provoke social unrest.
