The crucial role evaluation can play in the co-development of project design and its implementation will be addressed through the analysis of a case study, the Green Communities (GC) project, funded by the Italian Ministry of Environment within the EU Interregional Operational Program (2007-2013) "Renewable Energy and Energy Efficiency". The project's broader goals included an attempt to trigger a change in Italian local development strategies, especially for mountain and inland areas, which would be tailored to the real needs of communities, and based on a sustainable exploitation and management of the territorial assets. The goal was not achieved, and this paper addresses the issues of how GC could have been more effective in fostering a vision of change, and which design adaptations and evaluation procedures would have allowed the project to better cope with the unexpected consequences and resistances it encountered. The conclusions drawn are that projects should be conceived, designed and carried out as dynamic systems, inclusive of a dynamic and engaged evaluation enabling the generation of feedbacks loops, iteratively interpreting the narratives and dynamics unfolding within the project, and actively monitoring the potential of various relationships among project participants for generating positive social change.

Abstract This study aims to assess the efficiency of the fossil fuel taxation scheme currently in effect in Switzerland. To this end, the concept of implicit CO2 prices is introduced, based on which prices for different fossil fuel uses are derived. Implicit CO2 prices are defined as the difference between actual prices paid by consumers and efficient domestic fuel prices. Efficient domestic fuel prices, in turn, consist of private production costs, a uniform value added tax and only local external costs, not including external costs due to CO2 emissions and global climate change. The resulting prices differ substantially, which suggests that there is considerable cost-saving potential in reducing CO2 emissions in Switzerland. For passenger cars and air traffic, the implicit prices are negative. For these uses, higher fuel charges would therefore be beneficial from a purely domestic perspective, i.e., without considering the negative repercussions of global warming.

In the last thirty years of the twentieth century we saw a resurrection of the writings of Matlhus. In their new guise we are told that instead of war, pestilence and famine, the earth has decreasing biodiversity, loss of species, loss of natural resources and water shortages, to name but a few, to look forward too. Population growth today, as it was two hundred years ago, is portrayed as Public Enemy number one. There is little doubt that the Neo-Malthusian argument has made an impact on policy, indeed, probably moreso than did its namesake. The newly clad argument shares much with its namesake, not least, its significant faults. The argument is two hundred years old, and the inaccuracies share that age. Malthus' predictions never reigned true because he made the fundamental error of not taking account of technical progress, or the ability of human ingenuity to adapt to change. This paper looks at the evolution of both sides of the population argument, and argues that this year's World Summit in Johannesburg should not fall foul to the dangerous generalisations invoked by the Neo-Malthusian school of thought. This paper is an attempt to lay the blame for environmental degradation not on the increasing population of the Third World, but on the consumption patterns and lifestyles of the First World. Affluence consumes energy and produces waste at a far higher rate than poverty. In looking at the environmental debate only an integrated approach, and not one that is concerned solely with ‘demonising’ population growth, can result in success.

Abstract The paper aims to discuss the speedy spread of the use of optical fibres or optical light films lighting systems, as an alternative to classical lighting systems in buildings. A series of architectural projects has been selected to provide more evidence about advantages of these new lighting equipement, in terms of thermal and lighting comfort together with low cost energy. As a matter of fact their efficiency has even lead some professionals to use them in some buildings after suppression of the initial lighting system. The fact that the optional fibres or optical light films are used in various spaces has enabled to hope for a development of their applications in interiors and especially public places, in hot contries where heat output from traditional lighting bulbs is more likely to provide discomfort and hence where requirement for air conditionning is unavoidably maximised.

Much of New South Wales and southern Queensland suffered from extreme drought from 2017 to 2019. This study models drought and bushfires impacts using VU‐TERM, a multi‐regional, dynamic CGE model. Prolonged drought pushed national real GDP to 0.7 per cent or more below base in 2018–2019 and 2019–2020. NSW’s real GDP fell relative to forecast by 1.1 per cent or $6.9 billion in 2018–2019 and 1.6 per cent or $10.2 billion in 2019–2020. These impacts reflect a severe diminution of farm output, given that agriculture accounts for around 1.6 per cent of NSW’s income. Bushfires exacerbated 2019–2020 losses. We assume that there is a full recovery in seasonal conditions in 2020. However, prolonged drought and bushfire destruction deplete farm capital through depressed investment and diminished herd numbers. Consequently, the income earning capacity of farms in recovery remains below that of a no drought base. The net present value of the national welfare loss is $63 billion, split between $53 billion in losses from drought and $10 billion from bushfires. The latter excludes any valuation of human lives lost, flora, fauna or forestry destruction. In the longer term, adaptation and policy responses will need to reflect the expectation of increased frequency of adverse climatic events.

Abstract This paper examines the determinants of state gasoline consumption per household in the USA using pooled time-series cross-section data for the period 1966–1980. It was found that gasoline price, fuel efficiency of vehicle stock, percentage of population in metropolitan areas, and non-automobile transport modes have negative effects on consumption, while per capita income, number of vehicles, non-agricultural employment per household, age 18–44, warm weather, visits by out-of-state automobiles, and share of buses and trucks have positive effects on consumption. Holding constant the size of vehicle stock and its fuel-efficiency characteristics, the short-run price elasticity of gasoline was found to be -0.321 for the period 1966–1973 and -0.106 for the period 1974–1980. It was also found that gasoline demand experienced a temporary shift both in the intercept and in the price coefficient during the shortages of 1974 and 1979, and had undergone a permanent shift in the same parameters during the post-embargo period.

The belief that the price mechanism can be used exclusively to combat problems arising from growing energy shortages has led to the neglect of the repercussions of energy conservation on the macroeconomic problems of growth and development. Moreover, many studies consider only the direct effects of energy use and concentrate on petroleum shortages, so underestimating the total repercussion and structural dependence associated with changes in energy demand in Australia. This study attempts to overcome these gaps by modifying input-output modelling to estimate all primary energy demand for fossil fuels in Australia. The complex interactions between energy conservation and macroeconomic goals are investigated at sectoral levels. The optimal sectors that meet macroeconomic goals and energy constraints simultaneously have been identified using simple, but powerful, analytical tools. The tradeoffs between energy use and macroeconomic objectives are quantified using energy as a numeraire. The conflicts that emerge between macro-planning criteria and energy use efficiency are exemplified and the need to reconcile them using the value judgements of political decisionmakers is clarified. The limitations and the scope for refinement of the methodology are also discussed.

Abstract We extend the commonly-studied definition of investment in sustainable and energy efficient real estate beyond environmental building certification to include three additional types of environmentally-focused building interventions: environmentally-focused capital expenditure (capex); monitoring; and, tenant engagement. Appealing to behavioral economics and finance theory, we test for a connection between changes in tenant and property management behavior and electricity consumption. Through a partnership with a global institutional investment manager, this study examines ten years of asset-level operating statement and electricity consumption data in Canadian and U.S. office buildings, measuring both the initial impact of such interventions as well as any adjustments observed over time. Analysis of the proprietary intervention data allows us to better understand the impact of varied environmental interventions on the electricity consumption of commercial real estate. We find that all four intervention categories, including building certification, are associated with decreased electricity consumption, with tenant engagement providing an immediate decrease that is maintained over time. Environmentally-focused capex is also associated with decreased electricity consumption in both Canada and the U.S. Taken together the results indicate that utility consumption and its associated costs are only minimized when multiple environmental interventions are implemented.

PurposeThis paper aims to examine the complex issue of the social cost of carbon. The authors review the existing literature and the strengths and deficiencies of existing approaches. They introduce a simple methodology that estimates the amount of “legal looting” in the fossil fuel industry as an alternative approach to calculate an unpaid social cost of carbon. The “looting amount” can be defined as society’s failure to charge fossil fuel firms for the damage that their activities cause represents an implied subsidy.Design/methodology/approachThe methodology used in this paper combines decisions in the form of policymakers setting carbon taxes and rational investors investing in carbon emission markets.FindingsThe authors show that the unpaid social cost of carbon in the fossil fuel industry was US$12.7tn over 1995-2013, but may be as high as US$115.5tn.Originality/valueOver the same period, the sum of industry profits, emission trading scheme carbon permit and carbon tax revenue totalled US$7tn, indicating the industry would not be viable if it was made to pay for damages to society.
