《The British Accounting Review》2017,49(1):25-38
This exploratory study is amongst the first to investigate how companies perceive the regulation of carbon emissions and the pressure exerted by the community in an environment characterised by risk and uncertainty. Semi-structured interviews were conducted among 39 executives who were directly involved in carbon emissions management in 18 large listed Australian companies. Consistent with Prospect Theory, we find that decision-makers are threat biased and are more likely to take immediate actions when climate change issues are framed as threats as opposed to opportunities. From the interview data, it is seen that managers use management accounting techniques as a risk management tool in mitigating risks associated climate change issues. Furthermore, this use of management accounting appears to be driven primarily by the protection of economic interests, regulatory pressure and reputational pressure. The study provides insights into how perceptions of climate change uncertainties and external pressure for disclosure of emissions information influence companies to use management accounting in managing climate change risk. 相似文献

The impact of population growth and climate change on food security in Africa: looking ahead to 2050
Providing nutritious and environmentally sustainable food to all people at all times is one of the greatest challenges currently facing society. This problem is particularly acute in Africa where an estimated one in four people still lack adequate food to sustain an active and healthy life. In this study, we consider the potential impact of future population growth and climate change on food security in Africa, looking ahead to 2050. A modelling framework termed FEEDME (Food Estimation and Export for Diet and Malnutrition Evaluation) was used which was characterized to model the impacts of future climate changes (utilizing the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios projections) and projected population growth on food availability and subsequent undernourishment prevalence in 44 African countries. Our results indicate that projected rapid population growth will be the leading cause of food insecurity and widespread undernourishment across Africa. Very little to no difference in undernourishment projections were found when we examined future scenarios with and without the effects of climate change, suggesting population growth is the dominant driver of change. Various adaptation options are discussed, such as closing the yield gap via sustainable intensification and increasing imports through trade and aid agreements. These strategies are likely to be critical in preventing catastrophic future food insecurity. 相似文献

Since climate change mitigation likely will affect most sectors of society, adapting to climate change essentially requires the public to envision and adjust to alternative futures. There is a need for more studies on the social basis for climate change asking why people hold the attitudes they do, rather than the dominant tendency to ask how to change attitudes and behavior. Research in different fields show that fundamental life values and worldviews are shaped through life and heavily influenced by early life socialization and culture, which in turn can shape attitudes toward specific phenomena like climate change. We surveyed a representative sample of the Norwegian public and examined how cultural resources and trust in environmental governance institutions are related to attitudes toward climate change. High levels of trust are associated with a tendency to perceive climate change as human caused, and low levels of trust correspond with stronger beliefs that climate change are natural phenomena. High levels of cultural resources are found among climate change deniers as well as believers, indicating that groups with different political, professional and intellectual orientations, as well as life histories, may not trust climate change science. We argue that improved knowledge about the social basis for climate change is an imperative part of futures-oriented expertise. 相似文献

In this article we describe how the historical emergence and rise of future studies, since the founding issue of Futures in 1968, has been intricately connected to the emergence and development of environmental anticipation as discourse and practice. We trace a dialectical and inter-twined relationship between technologies of environmental anticipation and forecasting, and technologies of anti-environmentalist anticipation and counter-intervention, one which we argue shapes not only the contemporary politics of anticipation, but in a very material sense, the future conditions of biological and social life on Earth. In so doing we want to address the possible contributions that the field of futures studies can make to reimagining collective agency and ways of being on Earth, whilst reflecting critically upon its genealogical relations to the political reason and strategic horizons of powerful fossil fuel interests, from the crisis of the 1970s to the present. The article also offers a more in-depth contextualization to the other articles in this special issue of Futures on “The Politics of Environmental Anticipation”. The aim is to bring to the fore the role that social scientists play in environmental anticipation − i.e. drawing attention to the fact that the future could always have been otherwise. 相似文献

One of the main issues with the concept of ecosystem services is its absence on the ground in concrete operational decision-making contexts; that is, an implementation gap. In this study, we investigated if this gap could be overcome through the use of open-source data and free tools, and the adoption of a short-term participatory process. We tested these methods in the context of a project in the urban metropolitan area of Bordeaux (Communauté urbaine de Bordeaux: CUB) in France. The ecosystem services were defined using a participatory approach involving local stakeholders, and then selected scenarios were simulated to test the impact of various development or conservation plans. The study addressed three main questions: (1) Is it possible to adopt a simple methodological approach that overcomes the implementation gap through the development of a user-friendly and inclusive method? (2) What is the added value of a participatory approach? (3) With regards to four scenarios in this territory, what are the ES trends in the selected biophysical and monetary indicators, and will knowledge of these trends help planners to shape a sustainable trajectory for the territory? 相似文献

Reducing or altering meat consumption has the potential to significantly lower the impact humans have on climate change. Consumers, however, are unlikely to break their food habits unless they are aware of the problem and motivated by the solutions. Fear appeals are often used to overcome this, however, their effectiveness in the context of meat reduction and climate change is unclear. Given the widespread use of fear appeals in information policy, it is important to understand more. The aim of this study was to explore fear—or more specifically—the danger control process in a climate change—food context in order to understand the factors which motivate consumers to reduce or alter their meat consumption. Using a stratified random sample of 222 respondents in Southern Sweden, we develop a model for predicting intentions to adopt specific and general actions to reduce or alter meat consumption. Our results suggest that the general key to motivating consumers is through increasing their self-efficacy towards adopting meat alternatives and educating them on the importance their actions have in reducing the threat. We also found that appraising the threat to self (or those close) was significant, but surprisingly the effect size was greater when the threat concerned others (e.g. others in impoverished nations, animals). 相似文献

Estimation of ecosystem service values is a hot area of research in ecological conservation and economics. However, the costs of these outputs are largely unknown. In this paper, we estimated the opportunity cost of water allocated to afforestation projects through mathematical modeling based on statistical data for all of China to provide support for restoration planning based on a fuller consideration of the true costs. To guide future ecological conservation and environmental policy development, we illustrate a neglected concept (ecosystem service costs) and use this concept to compare the ecological services provided by ecological restoration based on afforestation with those of restoration based on the conservation of natural vegetation using data obtained since 1949 in China. The results showed that afforestation and natural vegetation create annual costs related to use of the available water resources equal to 4800 and 3700 RMB ha−1, respectively, representing a water opportunity cost of 1100 RMB ha−1 for afforestation. This illustrates the rule that “there is no free lunch” for any service, including ecosystem services. Therefore, to support the development of more effective and sustainable environmental restoration policy, it will be necessary to evaluate the associated opportunity costs. 相似文献

Natural personal care products are gaining popularity due to their benefits in terms of health and well-being. However, consumers are wary of these products and are guided by the fake news circulating about them. Since natural product consumption offers several personal and environmental benefits, it would be worthwhile to understand consumers’ tendency to let fake news influence their consumption decisions. Accordingly, the current study examined the association of fake news and purchasing behaviour towards natural personal care products, utilising Stimulus-Organism-Behaviour-Consequence (SOBC) as the theoretical framework. The study proposed openness to change as the stimulus, perceived benefits and perceived risks as organismic internal states, purchase intentions as the behaviour, and the propensity of believing and acting on fake news as the consequence, which is further associated with system trust. The model was tested by analysing data collected from 390 existing consumers, considering the moderation effect of brand trust and controlling the effect of age and gender. The findings confirmed that openness to change is associated with perceived benefits and risks. Furthermore, perceived benefits and system trust are associated with purchase intentions, which are, in turn, associated with the propensity of believing and acting on fake news. The study presents several novel contributions to theory and practice. 相似文献

Based on a survey of climate change experts in different stakeholder groups and interviews with corporate climate change managers, this study provides insights into the gap between what information stakeholders expect, and what Australian corporations disclose. This paper focuses on annual reports and sustainability reports with specific reference to the disclosure of climate change-related corporate governance practices. The findings culminate in the refinement of a best practice index for the disclosure of climate change-related corporate governance practises. Interview results indicate that the low levels of disclosures made by Australian companies may be due to a number of factors. A lack of proactive stakeholder engagement and an apparent preoccupation with financial performance and advancing shareholders interest, coupled with a failure by managers to accept accountability, seems to go a long way to explaining low levels of disclosure. 相似文献
