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.

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.

AbstractEmbedding sustainability in day‐to‐day operations necessitates employees' proactiveness beyond compliance with standardised management practices. Exchanging information on safety and environmental issues is acknowledged as a component of workers' proactive behaviours for sustainability embeddedness, which is hardly promoted by codified procedures. Accordingly, identifying leverages to stimulate information exchange is a primary objective for academics and practitioners. The study investigates drivers of information exchange on safety and environmental near misses by examining five situation‐related antecedents: rewards/reinforcements, organisational boundaries, social proactiveness, stakeholder salience and connectedness. The study relies on a mixed method approach, by combining social network analysis and a questionnaire survey conducted among four large Italian companies. The findings partially support the hypothesis of the study, highlighting rewards/reinforcements and connectedness as relevant antecedents of information exchange, while organisational boundaries only partially relate with information exchange. Surprisingly, stakeholder salience and social proactiveness do not emerge as significant drivers of information exchange. The study contributes to the debate on extra‐role pro‐sustainability behaviours and provides implications for managerial practice.

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.

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.

Much of the debate on sustainability is predicated on the belief that environmental demands lead to the production of sustainable technologies that induce environmental benefits. This fails to account for the influential ways technologies are used in practice, and the interactions between users and technologies that shape their environmental effects. This article uses the example of how cars and their drivers together accomplish the practice of driving through their interactions with each other, and explores the implications this has for generating environmental outcomes. We draw on a body of literature that argues how together, users and technologies participate in carrying out practices that actively shape outcomes, and we show how and why this applies to sustainability. The article presents the case of the Toyota Prius, analyzing Toyota’s intent in designing a sustainable car and contrasting it with the perspectives of thirty-eight of its drivers. We find that the possibility for fuel and carbon reduction is coproduced and is a result of complex interactions between technology, drivers, and driving practice.

In this work, we consider the practical issues of resource allocation problem in OFDMA two-way relay networks: the inaccuracy of channel-state information (CSI) available to the transmitters. Instead, only the estimated channel status is known by the transmitters. In this context, a joint optimization of subcarrier pairing and allocation, relay selection and transmit power allocation is formulated in the OFDMA two-way amplify-and-forward relay networks. Moreover, to ensure the Quality of Service (QoS) requirement, the energy consumption must be minimized without compromising the QoS. Therefore, by applying convex optimization techniques, energy efficient algorithms are developed with the objective to minimize the total transmit power while guaranteeing the required data rates. Through simulation studies, energy consumption performance of the systems under the proposed schemes are investigated. It is shown that the proposed scheme can improve the energy consumption performance without scarifying the QoS.
