Fossil fuel divestment: implications for the future of sustainability discourse and action within higher education

This paper provides a critical overview and analysis of the student-led fossil fuel divestment (FFD) movement and its impact on sustainability discourse and actions within US higher education. Analysing higher education institutes’ (HEIs) divestment press releases and news reports shows how institutional alignment with cultures of sustainability and social justice efforts played key roles in HEIs’ decisions to divest from fossil fuels. Key stated reasons for rejection were: minimal or unknown impact of divestment, risk to the endowment, and fiduciary duty. Participant observation and interviews with protagonists reveal the intricate power structures and vested business interests that influence boardroom divestment decision-making. While some HEIs embrace transformative climate actions, we contend that higher education largely embraces a business-as-usual sustainability framework characterised by a reformist green-economy discourse and a reluctance to move beyond business-interest responses to climate politics. Nonetheless, the FFD movement is pushing HEIs to move from compliance-oriented sustainability behaviour towards a more proactive and highly politicised focus on HEIs’ stance in the modern fossil fuel economy. We offer conceptual approaches and practical directions for reorienting sustainability within HEIs to prioritise the intergenerational equity of its students and recognise climate change as a social justice issue. Fully integrating sustainability into the core business of HEIs requires leadership to address fundamental moral questions of both equity and responsibility for endowment investments. We contend that HEIs must re-evaluate their role in averting catastrophic climate change, and extend their influence in catalysing public climate discourse and actions through a broader range of external channels, approaches, and actors.     

Fossil fuel divestment in US higher education: student-led organising for climate justice

Based on over one year of participant observation within the student-led fossil fuel divestment (FFD) movement, this article contextualises the origins, successes, challenges, and inner workings of the FFD movement in US higher education. We analyse several college divestment campaigns to illuminate key factors that have contributed to wins and rejections, and explore why students continue to organise for FFD. It is our contention that such widespread mobilisation for FFD signals a sea change, from individualised sustainability efforts to youth-led collective political action, and recognition of climate change as a social justice issue. In addition to participant observation, we gathered data from 23 survey responses of organisers involved in divestment campaigns within higher education, and 40 interviews with individuals including student and professional organisers within the FFD movement, institutional decision-makers at campuses with FFD campaigns, and other experts in the area. Our analysis also reveals that relatively smaller endowments and, more importantly, institutional values of environmental sustainability and social justice played key roles in colleges’ decision to divest. Our examination of divestment “losses” illuminates common arguments administrators deploy in their rejection statements, including the perceived costs of divestment, the need to maintain fiduciary responsibility, and scepticism that divestment will have any impact on the fossil fuel industry. Finally, in spite of increasing resistance from college and university administrations, student divestment campaigns continue to escalate, and are committed to organising over the long term.     

Is Nuclear Power Environmentally Sustainable?

The sustainability of nuclear energy is discussed in terms of its environmental impacts and its utilization of resources. The reactors in the present generation of fission reactors extract only a small percentage of the energy available from uranium. A solution to the long-term management of highly radioactive used reactor fuel is also a key factor in fission's sustainability. Recycling used fuel for enhanced energy production in advanced reactors and the mitigation of the long-term management of the remaining wastes, ideally with their ultimate destruction by nuclear transmutation, are technologies that need to be developed in order to ensure the long term sustainability of nuclear fission. In contrast, nuclear fusion, while not yet available for power production, promises to be inherently sustainable.     

Comparing Scales of Environmental Effects from Gasoline and Ethanol Production

Understanding the environmental effects of alternative fuel production is critical to characterizing the sustainability of energy resources to inform policy and regulatory decisions. The magnitudes of these environmental effects vary according to the intensity and scale of fuel production along each step of the supply chain. We compare the spatial extent and temporal duration of ethanol and gasoline production processes and environmental effects based on a literature review and then synthesize the scale differences on space–time diagrams. Comprehensive assessment of any fuel-production system is a moving target, and our analysis shows that decisions regarding the selection of spatial and temporal boundaries of analysis have tremendous influences on the comparisons. Effects that strongly differentiate gasoline and ethanol-supply chains in terms of scale are associated with when and where energy resources are formed and how they are extracted. Although both gasoline and ethanol production may result in negative environmental effects, this study indicates that ethanol production traced through a supply chain may impact less area and result in more easily reversed effects of a shorter duration than gasoline production.     

The Environmental sustainability of mining in Australia: key mega-trends and looming constraints

At first ‘sustainable mining’ could be perceived as a paradox—minerals are widely held to be finite resources with rising consumption causing pressure on known resources. The true sustainability of mineral resources, however, is a much more complex picture and involves exploration, technology, economics, social and environmental issues, and advancing scientific knowledge—predicting future sustainability is therefore not a simple task. This paper presents the results from a landmark study on historical trends in Australian mining, including ore milled, ore grades, open cut versus underground mining, overburden/waste rock and economic resources. When complete data sets are compiled for specific metals, particular issues stand out with respect to sustainability—technological breakthroughs (e.g. flotation, carbon-in-pulp), new discoveries (e.g. uranium or U), price changes (e.g. Au, boom/bust cycles), social issues (e.g. strikes), etc. All of these issues are of prime importance in moving towards a semi-quantitative sustainability model of mineral resources and the mining industry. For the future, critical issues will continue to be declining ore grades (also ore quality and impurities), increased waste rock and associated liabilities, known economic resources, potential breakthrough technologies, and broader environmental constraints (e.g. carbon costs, water). For this latter area, many companies now report annually on sustainability performance—facilitating analysis of environmental sustainability with respect to production performance. By linking these two commonly disparate aspects—mining production and environmental/sustainability data—it becomes possible to better understand environmental sustainability and predict future constraints such as water requirements, greenhouse emissions, energy and reagent inputs, and the like. This paper will therefore present a range of fundamental data and issues which help towards quantifying the resource and environmental sustainability of mining—with critical implications for the mining industry and society as a whole.     

Mobilising social energy against environmental challenge: understanding the groundwater recharge movement in western India

This paper explores a large-scale and growing popular movement to augment groundwater recharge in the Saurashtra region of western India, an area that has been facing acute water scarcity and other associated problems. As a social phenomenon, the movement is at an early stage of its development. However, it is interesting to study it for many reasons. First, even a decade after it began, it is still growing in scale and following. Second, it is entirely spontaneous and internally driven, necessitating no public resources or support. Third, early indications are that its social and ecological impacts are beneficial and highly significant. Fourth, the movement was catalysed and spearheaded by spiritual and religious institutions, which made ingenious use of non-economic messages and motivators in forging a new natural resource ethic based on a broad, collective rationality among movement members. It appears, however, that beyond a threshold, the movement acquired a logic and energy of its own which might fuel its future sustainability and growth. Finally, the movement has important lessons to offer because mobilising social energy on such a scale and intensity can perhaps be one of most effective responses to many of the environmental challenges the world faces today.     

Wells and well-being: neoliberalism and holistic sustainability in the shale energy debate

Based on semi-structured interviews with 31 Ohioans, this article argues that individuals who are concerned about shale energy development draw from a discursive framework that diverges dramatically from the position promoted by industrial proponents. While the oil and gas industry and its supporters largely embrace a neoliberal outlook that most closely correlates well-being with economic growth, citizens troubled by such development are guided by a more holistic perspective that links well-being to numerous interrelated non-economic elements including human health, community continuity, political empowerment, and environmental sustainability. This work contributes to an emerging understanding of how environmental change and socionatural well-being converge in the novel context of shale energy development and aims to give voice to those who cope with the direct consequences of twenty-first-century fossil fuel extraction. Approaching discourse – defined here as shared communication patterns that simultaneously reproduce and generate distinctive understandings of the world – as a dynamic arena of sociopolitical struggle, I further suggest that shale energy opponents use holistic sustainability discourse to actively or implicitly challenge neoliberal strategies for guiding thought and governing action.     

Energy,exergy analysis,and sustainability assessment of different engine powers for helicopter engines

The rapid decrease of energy resources has accelerated studies on energy efficiency. Energy efficiency refers to the effective use of energy, in other words, completing a specific task to the required standard by using less energy. Exergy is an effective instrument to indicate the effective and sustainable use of energy in systems and processes. Transportation is an important part of human life. The studies on energy saving and the effective use of energy in different areas around the world have also increased for transportation systems and vehicles. With the more effective use of fuel, there will be potential benefits for the environment as well as a reduction in operating costs. This study includes energy and exergy analyses as well as a sustainability assessment by using C₈H₁₆ as a fuel at different engine powers (150–600 SHP (shaft horse power)), for the piston-prop helicopter engine. The maximum exergetic sustainability index was found at the power that provided the maximum energy and exergy efficiency. As a result of this index, the lowest waste exergy ratio, the lowest exergy destruction factor, and the lowest environmental impact factor were obtained. The highest exergy destruction and the highest exergy loss value were obtained at maximum power (600 SHP).     

Bioenergy project appraisal in sub‐Saharan Africa: Sustainability barriers and opportunities in Zambia

Although there is continuing debate surrounding biofuel cultivation (especially in developing nations) in relation to issues of exploitation, land grabbing, poverty alleviation and energy security, there is a lack of empirical evidence to assess how these debates are playing out in practice on the ground. Drawing on political ecology discourse, this paper examines case studies of biofuel production in Zambia and the effects they have on environmental and social sustainability. During April and May 2011, data were collected on two case study projects involving Jatrophacurcas feedstock cultivation in Zambia. Semi‐structured interviews were used to ascertain views from affected stakeholders (local farmers, local environmental, social, and agronomic experts, and investors) on the biofuel projects and their environmental and social impacts. The findings suggest that the uneven distribution of costs and benefits are brought about by imbalances in knowledge, access to resources and the allocation of social and political influence (often associated with broader discourses of development), and this provides a likely rationale for a lack of sustainability in biofuel projects. Drawing on these viewpoints, as well as on field observations, this paper outlines the barriers and opportunities linked to Jatrophacurcas project sustainability.     

Sustainable regeneration: a guiding vision towards low-carbon transition?

While the concept of sustainable development brings together concepts of economic, environmental and social sustainability, much has been said regarding inherent tensions between them. Conflicts between economic and environmental objectives, in particular, have been noted as restraining efforts to instigate transitions to environmental sustainability, with growth ambitions limiting environmental policy to “win–win” cases. This paper argues that they can also play complementary roles in managing transitions by creating inclusive visions for rallying actors and resources. This is explored by looking at a case of sustainable regeneration in Wales, UK. Using as a case study the Arbed scheme, an area-based project established in 2009 to retrofit housing stock for energy efficiency, this paper shows how the scheme explicitly addresses economic, environmental and social aspects of sustainability; and, in particular, how sustainable development aims constituted a guiding vision that supported the formation of actor and resource networks necessary for large-scale retrofitting.     

Energy production and sustainability: A study of Belo Monte hydroelectric power plant

The increase in energy demand due to economic and population growth necessitates the expansion of the Brazilian energy supply. Hydropower energy, a renewable energy source, arguably clean, presents an energy solution for many countries such as Brazil, with large hydric reservoirs, which help them reduce energy dependence on fossil and imported fuel sources. However, it must be emphasized that without careful planning, the creation of hydropower plants will cause severe social and environmental damage due to the large areas that need to be flooded for the implementation of these plants. The installation of hydropower plants floods vast forest areas, causing loss of biodiversity, displacement of native Brazilian people and riverside populations, and changes to the water acid levels and the natural course of rivers. To mitigate these effects, authorities must first conduct a study on installation possibilities and potential socio‐environmental consequences, to be interpreted and used by the agents involved. Aiming to analyze the social‐environmental impacts of the hydropower plants, this research seeks to investigate the capacity of mitigation of the negative effects of the implementation of the hydropower plants, specifically with regard to the Belo Monte plant, Brazil.     

Assessment of environmental footprint using geospatial approach to ascertain the Sustainable Development Goal 2030s of India

Utilization of natural resources has multiplied globally, resulting in serious environmental deterioration and impeding the achievement of the Sustainable Development Goals (SDGs). For the harmonious development of human nourishment and the balance of nature, it is vital to evaluate environmental segments' resource usage, transformation, and residue, referred to as ‘footprint,’ in order to highlight carrying capacity and sustainability. This analysis highlights the Environmental Footprint (EF) of India per state from 2010 to 2020 in terms of hectares per capita. This study evaluates India's biological, hydrological, energy, ecological, and pollution footprints, carrying capacity, environmental pressure, and environmental deficit using 17 distinct parameters categorized under the themes of biological resource, hydrological resource, energy resource, and pollution concentration. We proposed a reoriented methodology and EF concepts that determine India's footprint, carrying capacity, nature of sustainability, environmental pressure index, and its consequential links to the 2030 SDGs. As a result, the biological resources contributed to ~50% of the environmental footprint, while hydrological, energy, and pollutants made up the remaining. Between 2010 and 2020, Delhi, Uttar Pradesh, Bihar, and West Bengal had the highest EF, while Jammu and Kashmir and the north-eastern provinces had the lowest. During the research period, the ecological deficit in India has increased overall. India impedes the 2030 SDGs; therefore, the study provides a picture of resource consumption, waste generation, economic growth, and societal changes, enabling academics and policymakers to redefine or document policy for a more sustainable future.     

Factors affecting energy saving behaviour: a prospective research

The purpose of this study is to outline the theme of saving energy resources and its relationship with the preservation of the environment, as well as the importance of green marketing in achieving sustainability. The model of data collection was a survey conducted by self-administered questionnaire. After collection, the data were statistically analysed and interpreted. Most individuals claim to be concerned about environmental problems, with 68% of these belonging to the ‘Savers’ group. However, even though they may be concerned with environmental problems, the vast majority of individuals do not have any system of renewable energy in their homes, despite claiming that renewable energies are a viable option for protecting the environment. Women display behaviour that is more favourable to the saving of energy resources than do men. Educational levels are not significant for distinguishing the more pro-environmental individuals from the others.     

Alternative energy: Environmental and economic factors associated with renewable energy and creating new integrated energy management systems

At best, the future of alternative and renewable energy remains uncertain. Our dependency on fossil fuels is already depleting world supplies of coal and petroleum while increasing greenhouse gas emissions. Most assuredly, the ability of alternative energy, described in this article as biomass, hydrogen, wind, solar, and geothermal power, to compete and even integrate with fossil fuels will depend on several important variables: First, developing, as well as developed, countries must be willing to direct long-term public and private funding towards innovative energy technologies by increasing research and promoting public education. Secondly, the “bottom line” economics associated with alternative energy technology must clearly show a positive cost/benefit ratio. Revenues and not deficits are paramount to the sustainability of alternative energy. Lastly, many experts argue for the environmental benefits of alternative energy by way of carbon reductions. The 1997 Kyoto Global Warming Treaty requires the United States in particular to reduce carbon dioxide emissions from fossil fuel burning by 7 percent below 1990 levels. While many experts argue that reactions to global warming and the alternative energy benefits anticipated because of them are fiscally irresponsible and not worth the billions of tax dollars intended, we can be assured that a business-as-usual attitude will continue without increased government and public support.© 1999 John Wiley & Sons, Inc.     

Multicriteria Evaluation of Water Resources Sustainability in the Context of Watershed Management1

Kang, Min‐Goo and Gwang‐Man Lee, 2011. Multicriteria Evaluation of Water Resources Sustainability in the Context of Watershed Management. Journal of the American Water Resources Association (JAWRA) 47(4):813‐827. DOI: 10.1111/j.1752‐1688.2011.00559.x Abstract: To evaluate water resources sustainability at the watershed scale within a river basin’s context, the Water Resources Sustainability Evaluation Model is developed. The model employs 4 criteria (economic efficiency, social equity, environmental conservation, and maintenance capacity) and has 16 indicators, integrating them using their relative weights. The model is applied to evaluate the water resources sustainability of watersheds in the Geum River basin, South Korea. A geographic information system is employed to efficiently build a database for the indicators, and the values of the indicators are normalized using the probability distribution functions fitted to the datasets of the indicators. The evaluation results show that, overall, the water resources sustainability of the watersheds in the upper basin is better than other areas due to the good environmental conditions and the dam management policies of South Korea. The analysis of the correlations among the model’s components and the comparison between the results of the model and the Water Poverty Index show that the model can provide reasonable evaluation results for the water resources sustainability of watersheds. Consequently, it is concluded that the model can be an effective tool for evaluating the states of water resource management from the perspective of sustainable development and provide a basis on which to create policies for improving any inadequacies in watersheds.     

Exergetic Irreversibility and Sustainability Performances for Alternative Fuels in the Micro-Turbojet Engine

Design and modernization of the micro turbojet engine technology have an important problem related to fuel consumption in terms of economics and environmental. For this purpose, in this study, first, energy and exergy efficiencies of the Jet A-1 and seven different alternative fuels were examined. Then, Exergy—based sustainability indicators were evaluated via exergetic irreversibility seperately. For this purpose, operational data of SR-30 micro-turbojet engine was taken as reference. According to this, the exergy efficiencies of engine as fuel for blending of methanol and ethanol were fixed with 22.35% and 20.56%, respectively. At the end of the study, some evaluations about alternative fuels and sustainability were made.     

Ethanol fuels: Energy security,economics, and the environment

Problems of fuel ethanol production have been the subject of numerous reports, including this analysis. The conclusions are that ethanol: does not improve U.S. energy security; is uneconomical; is not a renewable energy source; and increases environmental degradation. Ethanol production is wasteful of energy resources and does not increase energy security. Considerably more energy, much of it high- grade fossil fuels, is required to produce ethanol than is available in the energy output. About 72% more energy is used to produce a gallon of ethanol than the energy in a gallon of ethanol. Ethanol production from corn is not renewable energy. Its production uses more non- renewable fossil energy resources in growing the corn and in the fermentation/distillation process than is produced as ethanol energy. Ethanol produced from corn and other food crops is also an unreliable and therefore a non-secure source of energy, because of the likelihood of uncontrollable climatic fluctuations, particularly droughts which reduce crop yields. The expected priority for corn and other food crops would be for food and feed. Increasing ethanol production would increase degradation of agricultural land and water and pollute the environment. In U.S. corn production, soil erodes some 18- times faster than soil is reformed, and, where irrigated, corn production mines water faster than recharge of aquifers. Increasing the cost of food and diverting human food resources to the costly and inefficient production of ethanol fuel raise major ethical questions. These occur at a time when more food is needed to meet the basic needs of a rapidly growing world population.     

Potential use of oil shale for direct production of power in Jordan

Up until the present, Jordan has relied almost exclusively on imported petroleum for its primary energy requirements. Encouraged by emerging technologies and recent fossil fuel discoveries, Jordanians are seriously examining exploitation of their own indigenous energy resources to meet projected mid- and long-term power requirements. The most prominent of the known resources is oil shale. This report addresses the oil shale-for-power-production option in Jordan. Under consideration are 20 MW and 50 MW demonstration units and a 400 MW commercial-scale plant. The report focuses on three areas: (i) the engineering feasibility of using Jordan's oil shale in a circulating fluidized bed combustion (CFBC) boiler; (ii) environmental aspects of the proposed oil shale-for-power plants(s); and (iii) the economic feasibility of the proposed plant(s). The results could be useful for other low- to middle-income countries considering oil shale as an option for power production.     

Integrating industrial ecology principles into a set of environmental sustainability indicators for technology assessment

This paper focuses on the environmental component of sustainability of technology, taking into account the role of industrial ecology. Assessment of environmental sustainability of technology traditionally focuses on immediate impact of technology on the environment through quantifying resource extraction and generated emissions. However, technology does not only exchange materials with the environment but also with the industrial society as a whole, the so-called industrial metabolism. A higher compatibility of a specific technology with the industrial system, as studied in industrial ecology, can result in lower resource extraction and reduced waste emission, indirectly contributing to a better environmental sustainability.Starting from the considerations above and based on the second law of thermodynamics, the paper presents a set of five environmental sustainability indicators for the assessment of products and production pathways, integrating industrial ecology principles. The indicators, all scaled between 0 and 1, take into account: (1) renewability of resources; (2) toxicity of emissions; (3) input of used materials; (4) recoverability of products at the end of their use; (5) process efficiency.The applicability of the elaborated set of indicators is illustrated for different production pathways of alcohols (petrochemical and oleochemical based), polyethylene end-of-life options and electricity production from non-renewable (natural gas and fossil oil) and renewable resources (hydropower, photovoltaic conversion of solar irradiation).     

Qualifying irrigation system sustainability by means of stakeholder perceptions and concerns: lessons from the Segarra‐Garrigues Canal,Spain

When planning interventions, water and land resource managers increasingly need to take the opinions of stakeholders into account. In the present study, stakeholders’ concerns in a multifunctional water system are assessed, with a focus on the debate about the sustainability of irrigation projects in stressed and competing water contexts. The selected case study pertains to the Segarra‐Garrigues irrigation canal (Spain), the promotion of which has generated social debate and mobilization, as well as pronouncements from European authorities for ensuring its environmental sustainability. Data was collected through semi‐structured interviews and analysed by means of a new codification system for identifying the affinities and conflicts arising from existing water demands. Results show that sustainability concepts are more present in civil society than in public administration and private services or the rural community. However, social sustainability and environmental sustainability are a priority for most stakeholders, while the economic perspective of sustainable development has been conditioned by the first two. These results can be used by relevant authorities as a first step in customizing their interventions, as they provide a clear initial idea of what stakeholder priorities are in the framework of sustainable development.
