Multiple Levels of Corporate Sustainability

According to Dr. Clare Graves, mankind has developed eight core value systems,1 as responses to prevailing circumstances. Given different contexts and value systems, a one-solution-fits-all concept of corporate sustainability is not reasonable. Therefore, this paper presents various definitions and forms of sustainability, each linked to specific (societal) circumstances and related value systems. A sustainability matrix– an essential element of the overall European Corporate Sustainability Framework – is described showing six types of organizations at different developmental stages, with different forms of corporate sustainability, each supported by specific institutional arrangements.     

Corporate communication,sustainability, and social media: It's not easy (really) being green

This empirical research explores how 16 global corporations from four different industry sectors—retail, technology equipment, food/beverage/tobacco, and consumer goods—use social media platforms and corporate social responsibility (CSR) reports to communicate about sustainability. Facebook, Twitter, CEO letters from annual reports and CSR/sustainability reports, and other company documentation are examined to compare the content and scope of these firms’ corporate communication. The sample is divided into two subsamples (Green and Not Green firms) using Newsweek's Greenest Company 2012 rankings, and compared for differential use of social media and corporate reports. Results show that communication varies across firm and industry regarding types of sustainability initiatives reported, metrics employed, and communication media utilized, and that Green firms are more active than Not Green firms both in addressing sustainability and in general social media activity. Implications are discussed herein and recommendations are presented for companies seeking to better understand the effective use of social media and sustainability communication.     

An utility-based decision support sustainability model in slow steaming maritime operations

This paper analyses slow steaming sustainability initiatives and generalizes the traditional discrete cost-based decision support model into novel continuous utility-based models. Two models based on logarithmic and linear utility functions are developed for risk-averse and risk-neutral decision makers respectively. The models, considering fuel consumption, carbon emission, and on time delivery, are applied to a Trans-pacific trade service route. A sensitivity analysis is conducted on parameters of sailing distance, expected transit time, quantity, and emission policies. The model contributes to ship liners on the optimal speed decisions in continuous utility-based slow steaming operations.     

An information-based adaptive strategy for resource exploitation in competitive scenarios

Given an exploitation problem, in which a number of agents compete for a limited renewable resource, the optimal harvesting strategy depends on the ratio between resource availability and exploitation effort. For scarce resource a purely competitive, greedy strategy outperforms a more collaborative approach based on the Collective Intelligence, while for more abundant resource the opposite holds. The rationale for this behaviour lies in the amount of information each strategy is able to provide and a combined strategy is possible according to which agents choose dynamically the most informative strategy according to a minimum entropy criterion. This approach, which provides best performance for both under and over-exploited scenarios, can be used to monitor the resource status for management purposes and is effective in both centralised and decentralised decision making.     

Learning teaching in the sustainability classroom

This article analyzes the experience of a particular sustainability learning classroom model, examining the classroom composition, structure, positioning, and atmosphere components in an experimental course on the topic of sustainable buildings. The course, called Angles on Green Building, offered as the second in a suite by the Learning City sustainability in higher education collaborative, experimented with content, which concerned the emerging practice and policy of green building, and with form, exploring the most appropriate pedagogical methods for the advancement of sustainability learning and action. The course took as its practical focus the green building industry in Vancouver, Canada, with an initial case study of the new Centre for Interactive Research on Sustainability (CIRS), a green building and research facility planned for completion in 2009. This article uses evidence drawn from the instructors, students and visiting professionals in the course, together a diverse and interdisciplinary group from four different higher education institutions in Vancouver. Our findings contain lessons about the careful attention needed for instructors to design, run and implement courses in sustainability topics that enable students from widely different backgrounds and levels of self-directedness to engage with, take responsibility for, and transform their behaviours in favour of sustainability.     

Marketing capabilities and innovation-based strategies for environmental sustainability: An exploratory investigation of B2B firms

While emerging literature on sustainability shows that environmentally responsible strategies can contribute to competitive advantage and enhanced financial performance, little is known about specific marketing capabilities that lead to sustainable consumption behavior, and whether implementing such strategies leads to firm competitive advantage. Using the case method approach, this study explores marketing-related strategies and practices pertaining to sustainable consumption as reported by leading sustainable firms in the B2B context. We examine case studies of forty seven B2B firms and identify key marketing capabilities that tie to innovation-based sustainability strategies, sustainable consumption behavior and firm performance. We use our findings to develop a conceptual framework linking marketing capabilities to innovation strategies for firm sustainability, sustainable consumption behavior and firm competitive advantage, and put forward propositions for future research.     

中国的外债管理问题

外债是弥补发展中国家资金不足的手段,更是促进贸易投资便利化的工具。两者共同构成了中国外债管理的"基石"。改革开放30年来,中国外债管理逐渐形成了服务实体经济的目标、循序渐进的改革思路和联合监管的模式。现阶段,中国的主要外债指标在合理区间内,既有实体经济的基础,又有充裕外汇资源的支撑。未来,深化外债管理体制改革应着力于提高外债统计的完整性和准确性,提高统筹"防风险"和"便利化"的监管能力。     

Supply chain environmental investments in dynamic industries: Comparing investment and performance differences with static industries

Research linking investments in environmental practices to firm performance has matured over the past years. However, empirical research is still ambiguous on how and whether investments in environmental practices improve a plant's performance. We believe that contingency factors, especially the industry in which plants act has a significant role in the success of environmental investments. Using empirical data collected across a wide range of industries our results indicate that plants competing in dynamic industries such as apparel do on average invest less in supply chain environmental practices compared to plants in static industries. In addition, these environmental investments do not significantly improve operational performance in dynamic industries in terms of cost, quality, delivery and flexibility. However, in static industries environmental investments do significantly improve a plant's operational performance in terms of cost, quality and flexibility.     

西方可持续性经济学研究的主要理论问题及其评价

可持续性经济学是20世纪60年代以来在西方经济学界逐渐形成并发展起来的一门新兴的、交叉型和应用型经济学科。尽管西方经济学界对可持续性经济学从概念、特征、研究范畴、研究方法和制度背景等诸多方面并没有形成一个统一而明确的认识,但可持续性经济学的有关理论已成为可持续发展实践的基础和重要指导。通过对西方可持续性经济学研究的主要理论问题进行梳理与评价,一方面可以揭示西方在该学科领域一些关键理论问题上的研究进展,另一方面也为我国构建具有中国特色、适合中国国情的可持续性经济学的理论和实践提供借鉴。
