ABSTRACTIn 2012, a total of 13.1 million tonnes of carbon dioxide were emitted by 14 airlines while transporting 72 per cent of international passengers into and out of Australia in 2012. With passenger and cargo traffic growing at between five to six per cent annually from 2013 to 2033, acquiring more fuel efficient aircraft to both renew the existing fleet and to service growth has the greatest potential in reducing emissions over the next 20 years. Our analysis shows that implementing carbon dioxide emissions abatement options such as installing light weight seats, iPad electronic flight bags, winglets, washing aircraft engines and reducing the number of engines used during taxiing, all offer net financial savings when considered over 20 years. Acquiring new fuel efficient aircraft has the biggest impact on emissions reduction. Low interest loans and longer loan repayment periods may incentivise airlines to acquire more fuel efficient aircraft to service traffic growth but other complimentary incentive...

While different in emphasis, spirituality and sustainable development are intertwined concepts that cannot be meaningfully discussed in isolation from each other. This is especially pertinent in Pacific Island countries that are characterised by both high degrees of vulnerability to climate change and high degrees of religious engagement. There is a paucity of research that examines the relationship between spirituality and sustainable development in contemporary human development discourse. To address this gap in the literature, this research employs an inductive and exploratory methodological approach to the study of major development organisations in Australia. It investigates what significance contemporary NGOs ascribe to matters of spirituality in the design and implementation of their community aid and development programming in the Pacific and beyond. To achieve its goal, the study conducts a systematic term frequency analysis in the annual reports of government-funded and independently funded NGOs, both faith-based and secular. It extends previous research by focusing expressly on the intersectionality of sustainable development and spirituality as a fertile space for interdisciplinary inquiry. The findings link development policy and practice more closely to the needs and worldviews of Pacific peoples. A better understanding of the spirituality–sustainability nexus will enable more effective, sustainable, equitable, ethical, and culturally acceptable development programming. Crucially, integrated approaches promise to make ongoing community development programmes and adaptation responses to climate-driven environmental change more effective and sustainable. Finally, it is an important aim of this study to conceptualise various opportunities for future research, thus laying the foundation for an important emergent research agenda.

This article examines a group of intellectual workers who occupy a peripheral but not powerless position in the global economy of knowledge. How do they handle relations with the global metropole, especially in new fields of research where established hierarchies are in question? Three new domains of knowledge – climate change, HIV/AIDS and gender studies – are studied through interviews with 70 active researchers in Southern-tier countries Brazil, South Africa and Australia. A pattern of extraversion, involving active adoption of paradigms from the metropole, is widespread and institutionally supported. Major alternative knowledge formations have not emerged in these domains. However contestations of more specific kinds are frequent. Paradigms are adapted, criticism is offered, activism is engaged, capacities are developed and allegiances sometimes changed. The valorization of local knowledge, which goes beyond the abstractions of universalized paradigms, is particularly significant. Not stark subordination, but a complex collective negotiation characterizes the response of intellectual workers in the Southern tier.

The purpose of this study is to estimate the economic value of Geomun Oreum (GO), a parasitic volcanic sieve, for sustainable management by using the dichotomous choice contingent valuation method. To address the exaggeration tendency of willingness to pay (WTP), the contingent valuation method’s (CVM’s) traditional threshold, respondents’ WTP answers were reconfirmed to screen only true responses for our analysis. In addition to estimating the economic value, the causal relationship between the tour guide’s quality of explanation and the respondents’ payment intention is examined in the study. The results reveal that the estimated preservation value of GO is 35,881 KRW (33.28 USD), and the quality of the tour guide’s narrative is statistically related to the respondents’ payment intention.

AbstractThe business model of as‐a‐service is rapidly spreading in the energy industry. This study aims to examine how servitization in the energy sector is progressing, what sectors are in the spotlight, and what their implications are. By understanding the servitization aspect of the energy sector, it is possible to gauge the direction of change in the energy industry. This study has reviewed various as‐a‐service types in the energy sector through new articles analytics. For a total of 6 years from 2015 to 2020, news articles containing keywords related to the energy industry and the term “as a service” were extracted from Google News using the R package. As a result, well‐known as‐a‐service models such as software‐as‐a‐service and platform‐as‐a‐service are being emphasized in the energy sector. Also, new types of services such as zero‐carbon‐as‐a‐service and resilience‐as‐a‐service have been emerging recently. With the spread of as‐a‐service, the value chain structure of the energy industry is expected to shift towards various types of services and platforms. Servitization, represented by as‐a‐service, is becoming a trend in the energy industry, and policy and regulatory support to foster the data industry and expand opportunities to demonstrate innovative technologies and services is required.This article is categorized under: Policy and Economics > Governance and Regulation Policy and Economics > Research and Development

Public transportation can have an efficient role ingainingtraveler satisfaction while decreasing operation costs through establishing an integrated public transit system. The main objective of this research is to propose an integrated multimodal transit model to design the best combination of both railway and feeder bus mode transit systems, while minimizing total cost. In this paper, we have proposed a strategy for designing transit networks that provide multimodal services at each stop, and for consecutively assigning optimum demand to the different feeder modes. Optimum transit networks have been achieved using single and multi-objective approaches via metaheuristic optimization algorithms, such as simulated annealing, genetic algorithms, and the Non-dominated Sorting Genetic Algorithm II (NSGA-II). The used input data and study area were based on the real transit network of Petaling Jaya, located in Kuala Lumpur, Malaysia. Numerical results of the presented model, containing the statistical results, the optimum demand ratio, optimal solution, convergence rate, and comparisons among best solutions have been discussed in detail.

In conventional building design projects architects make pre-design and conceptual design decisions on buildings and hand these down to structural and building services engineers to follow up with design development. It is well known that the conceptual design stage of a project is the point where decisions make the most impact, and changes can be made at least cost. The sustainability and innovation aspects of projects often suffer in this respect. One way of addressing this is through Integrated Design Methods that set out mobilise the full potential of all design disciplines on a project by getting them to work effectively together. This method involves architect, engineers, contractors, and owners/clients in all design phases. The current literature reported fundamental principles and processes of Integrated Design however current industry practices do not fully embrace them. Introducing integrated design studios into university pedagogies is a key step in addressing this. Reports on methods of setting up integrated design studios in a university context are however rare. The aim of this article is to develop and document the underlying settings for such design studios. The principles and best practices for applying integrated design are identified. A specific framework of settings in university context is developed and the justifications presented. This article may be of value for the industry and universities to setup integrated design studios to better foster integrated design education.

Abstract We model game-theoretic situations in which agents motivated by Kantian ethics interact with conventional Nashian agents. We define the concept of generalized Kant–Nash equilibrium which encompasses the Nash equilibrium, the Kantian equilibrium and the Kant–Nash equilibrium as special cases. We show the existence and uniqueness of a Kant–Nash equilibrium in a static game of climate change mitigation, and derive its properties. In a dynamic setting, we analyze a differential game of climate change mitigation in the presence of both types of agents, and compare their Markov emission strategies. For both the static model and the dynamic model, as the population share of Kantians increases, the quality of the environment improves, and both types of agents are better off.
