An introductory note on the environmental economics of the circular economy

This paper provides an introduction to some of the fundamental principles and approaches in environmental economics which are of significance to achieving an integrated sustainability science. The concept of a circular economy, introduced by the late David Pearce in 1990, addresses the interlinkages of the four economic functions of the environment. The environment not only provides amenity values, in addition to being a resource base and a sink for economic activities, it is also a fundamental life-support system. Environmental economists have suggested that, taking these four functions as an analytical starting point, unpriced or underpriced services should be internalised in the economy. In Europe significant advances have been achieved in the pricing of externalities by means of truly interdisciplinary analysis which accounts in detail for the environmental consequences. The monetary estimates reached as a result of such interdisciplinary research are gradually being applied to the economic analysis of environmental policy priorities. Although such figures provide only a partial and incomplete picture of the environmental costs at stake, they support and inform the analysis of the virtues of a circular economy for individual resources as well as for sustainability as a future trajectory.     

From frontier economics to an ecological economics of the oceans and coasts

Ecological economics is a field of enquiry that has had, with a few exceptions, an almost entirely terrestrial focus. Given the fundamental ecological and economic importance of oceanic and coastal ecosystems, and the accelerating deterioration of these ecosystems, we argue that there is an urgent case to redress this imbalance. In so doing, the scope of ecological economics will be extended and compelling insights developed and applied to better understand and govern marine systems. Although we acknowledge that there is no unequivocal or unitary view of what might constitute an ecological economics of the oceans and coasts, we assert that it should consist of at least ‘four cornerstones’: (1) sustainability as the normative goal; (2) an approach that sees the socio-economic system as a sub-system of the global ecological system; (3) a complex systems approach; and (4) transdisciplinarity and methodological pluralism. Using these four cornerstones, we identify a future research agenda for an ecological economics of the oceans and coasts. Specifically, we conclude that ecological economists must work with other disciplines, especially those involved in marine policy and practice, to move from a ‘frontier economics’ (which has dominated marine management) to entrench an ‘ecological economics’ of the oceans and coasts as the dominant paradigm.     

ImPACTS框架下西北典型生态经济问题研究综述

与传统学科界限鲜明不同,生态经济学强调跨学科交叉研究,注重让问题来决定研究工具集,而不是由研究工具来决定合适的对象。由于生态经济问题涉及生态系统与社会经济系统,研究对象属性多样、关系复杂,既有采用传统意义上的生态经济学方法如生态系统服务价值核算等方法,也包括生活质量、生计途径、消费评估等社会学方法。因此,采取关注学科主要方法发展演化的思路,难以系统地总结生态经济研究进展。我国西北地区生态环境脆弱,经济发展相对落后,无疑是生态经济研究的"天然典型实验场",取得了大量的研究成果。遵循从研究对象出发的思路,采用经典的ImPACTS等式框架,以更宽泛的视野和系统的思维框架综述了西北地区典型生态经济实证研究的思路,即:采用等级层次分析方法研究生态系统和经济系统某个或多个结构性成分及其关系,再用实际结果检验其正确性。综述重要进展包括:可持续性衡量从物质、能量和信息角度开展了水资源承载力、生态足迹、能值与上升性的研究;生态系统服务和自然资本的价值评估开展了条件估值和选择模型,以及环境经济账户、物质流等集成核算工作;人类福利状况评价开展了幸福及生活质量核算工作;开展了生态补偿全流程的实证研究工作;集成模拟模型开展了空间建模环境的构建及简单自然过程的模拟,以LUCC和生态补偿为例进行了较好的自然过程和人文因素相耦合的集成模拟研究;以社会适应性能力作为整体性指标研究了社会资源对水资源的适应作用,将社会资源解耦为文化类型、社会资本和制度三个维度进行实证分析。在此基础上,提出了未来开展研究的建议。

Towards a new climate economics:research areas and prospects

International cooperation to address climate change now stands at a crossroads.With a new international regime for emissions reduction established by the Durban Platform, "New Climate Economics(NCE)" has become a research hotspot.The need for urgent action to combat climate change has prompted discussion on reforms of economic growth patterns and the energy system.The industrial civilization,therefore,now faces a transition towards a new pathway for ecological sustainability.NCE explores new economic concepts,theories,and analytical methods to design a balanced pathway for sustainable growth and emission reduction.Instead of getting trapped in discussions on allocation of emission reduction responsibilities and obligations among countries,NCE pays more attention to developing win-win multilateral cooperation mechanisms that facilitate collaborative RD and knowledge sharing.In addition,NCE studies incentives for low-carbon transition,turning carbon emission reduction into a domestic need for countries to increase their international competitiveness.To achieve the 2°C target,most countries around the world face challenges of insufficient emission allowances to cover expected emissions associated with their projected economic growth.As carbon emissions rights becomes an increasingly scarce resource,increasing the carbon productivity of the economy turns to be the critical path to address the dilemma of green or growth.NCE studies the historical evolution of carbon productivity for countries at different development stages as well as ways to enhance such carbon productivity.This type of study provides invaluable lessons for emerging economies to reach their own emission peaks without losing the momentum of growth.Replacing fossil fuels with new and renewable energy has proven to be an inevitable choice for reshaping the energy system and addressing climate change- it has already become a global trend.NCE studies incentives for new energy technology innovation and deployment provided by carbon pricing,and sheds light on the co-benefits of climate change mitigation,such as resource conservation,environmental protection,and energy security.The role of carbon pricing in promoting intemational RD cooperation and technical transfer will also be studied.The shift in consumption patterns is another key factor enabling a low-carbon transformation.Therefore,NCE also explores the theoretical work on new values of wealth,welfare and consumption,new lifestyles in the context of ecological civilization,concepts and implementation of low-carbon urban planning in developing countries,and the impacts of consumption pattern changes on social development,material production,and urban infrastructure construction.     

Corporations,Consumerism and Culpability: Sustainability in the British Press

Sustainability and sustainable development are prominent themes in international policy-making, corporate PR, news-media and academic scholarship. Its definitions are contested, however sustainability is associated with a three-pillar focus on economic development, environmental conservation and social justice, most recently espoused in the adoption of the UN Sustainable Development Goals in 2015. In spite of its common usage, there is little research about how sustainability is represented and refracted in public discourse in different national contexts. We examine British national press coverage of sustainability and sustainable development in 2015 in a cross-market sample of national newspapers. Our findings show that key international policy events and environmental and social justice frames are peripheral, while neoliberalism and neoliberal environmentalism vis-à-vis the promotion of technocratic solutions, corporate social responsibility and “sustainable” consumerism are the predominant frames through which the British news-media reports sustainability. This holds regardless of newspaper quality and ideological orientation.

Debating ecological justice: implications for critical environmental education

This article will briefly discuss the implications of recognition of ecological justice in relation to environmental education (EE) and education for sustainable development (ESD). It is argued that the present conception of environment taught through EE and ESD negates the subjectivity of non-human species and ignores the ethical imperatives of ecological justice. Evocating environmental ethics, major directions integrating ecological justice into EE and ESD are proposed.     

Genotoxic effects of binary mixtures of xenoandrogens (tributyltin, triphenyltin) and a xenoestrogen (ethinylestradiol) in a partial life-cycle test with Zebrafish (Danio rerio)

A partial life-cycle test with the model fish Danio rerio was performed in order to evaluate the genotoxic potential of binary mixtures of xenoandrogenic (tributyltin--TBT; triphenyltin--TPT) and an estrogenic compound (ethinylestradiol--EE2). Five days post-fertilisation larvae were diet-exposed to environmental relevant concentrations of TBT and TPT (25 ng/g-100 ng/g), and water-exposed to ethinylestradiol (3.5 ng/L) for a four-month period; binary mixtures of TBT plus EE2 and TPT plus EE2 were run in parallel. The erythrocytic nuclear abnormalities (ENA) assay in circulating erythrocytes was used to evaluate genotoxicity in the end of the four-month exposure period. A significant increase (p<0.05, Kruskall-Wallis non-parametric ANOVA) in ENA frequency, in comparison with control animals, was observed in those animals exposed to TBT and TPT (the highest doses only), and to EE2 and the binary mixtures, although neither synergistic nor additive effects of the tested compounds were evident. Overall, the results clearly indicate that chronic exposure to low levels of TBT, TPT, EE2 and binary mixtures of TBT plus EE2 and TPT plus EE2 are genotoxic to zebrafish, which may suggest that wild fish populations may be under increased DNA damage in areas contaminated by these endocrine disrupting chemicals.

Packaging redesign – benefits for the environment and the community

Abstract

This paper aims to underline the importance of the packaging redesign process and the potential benefits that can be derived from this for both the environment and the community. The research demonstrates that the redesign of paper corrugated packaging has cost savings for most links of the supply chain such as the industrial customers, retailers, wholesalers and final consumers. In addition, an applied case study will be used that aims to provide evidence that the redesign process could further offer weight and transportation benefits, provide better environmental performance and finally offer better protection for the packaged products. The alternative packaging suggestions made in the research refer to the secondary paper corrugated packaging since the objective is to show the value of the redesign process. The research provides the tools for a packaging designer, on how to estimate, analyse, redesign and compare different approaches, finding the way to a more sustainable packaging supply chain.     

The Role of Foreign Direct Investment in Urban Environmental Management: Some Evidence from Hanoi, Vietnam

In recent years flows of foreign direct investment (FDI) to developing countries have rapidly been increasing. It is now an important contributor to the national economy and urban growth in scores of developing countries. Rapid urbanization in these countries is leading to many problems in the cities. Existing urban infrastructure and municipal services have been unable to cope with the increased demand arising from growing population and rapid economic growth. Consequently, the environment in these cities has deteriorated alarmingly. This paper assesses the role of FDI in urban environmental management (UEM) by analyzing the linkages between them for Hanoi City in Vietnam. The paper's analysis and findings are presented under three main themes: one, FDI, employment and income; two, FDI and environmental degradation; and three, potential of utilizing FDI for the provision of urban environmental infrastructure and services (UEI&S) in order to improve the urban environment. Both primary and secondary source data have been used. Policy implications of the research findings are drawn from the perspective of sustainable development.     

气候变化经济学研究综述

对近10 a来国内外有关气候变化经济学研究成果作了综述。气候变化经济学是一门研究人类干预气候变化过程中涉及经济过程的学科。当前的研究热点包括气候变化的经济影响、适应措施的成本和收益、国际合作机制和涉及代际公平的折现率选取。 在研究方法上,对得到广泛运用的成本收益分析法和碳税机制作了详细的评述。在应用层面上,欧美发达国家在城市气候变化经济评估系统建立和碳税征收方面都有成功的应用,但我国在这方面的实践还处于起步阶段。对于我国气候变化经济学领域的研究来说,比较适合在发达省份以市域或省域为单位开展成本收益评估,发展中省份则应将更多关注放在评估气候变化可能造成的经济损害及相应的防范措施。此外,我国也应关注在欧盟地区实施较为成功的碳税政策,虽然目前在中国开征碳税的可能性较低,但是对碳税在中国实施的可行性、税率选取及立法保障机制等方面的探讨和研究仍是必要的     

The economics of handling refinery sludges

Methods of handling sludges generated from normal refinery operations are evaluated to determine the costs of alternative disposal methodologies. Sludges generated from several areas in the refinery are classified as (1) sludges from which oils may be recovered; (2) other oily sludges from which oils cannot be recovered; and (3) biological sludges. Methodologies for handling these sludges are reviewed based on previous experience. The economics of handling a representative combination of biological and oily sludges from the refinery are evaluated considering three disposal options: Alternative I in which the sludge would be dewatered using pressure filtration followed by landfill disposal of the sludge cake; Alteration II in which vacuum filtration was employed for sludge dewatering followed by sludge disposal in a landfill; and Alternative III in which the sludges were disposed of by landfarming. Costs are presented for centrifugation of oily sludges and incineration as a final disposal alternative.     

No Sustainability without Technical,Fiscal and Social Innovation

Abstract

Migration process has become increasingly important in recent research on population and the environment. A majority of the existing migration and environment literature has focused on the environmental causes and determinants of migration. With the largest rural-to-urban migration flow in world history, and growing concerns about the environmental problems accompanying its fast economic development, China provides a particularly important case for migration and environment research. This paper reviews major migration theories and recent research on environmental effects on migration, with specific attention to the influences of environmental factors on rural-to-urban labor migration in China. A comprehensive multilevel conceptual framework is developed for studying the environmental causes of rural-to-urban migration in China. The effects of land resources on household labor migration decisions in rural China are explored to illustrate the application of this framework.     

环境价值的多元不可比性及其字典式偏好研究

绝大多数环境物品属于非市场资源,没有市场价格,因此市场体制低估甚至忽视了环境的价值,这是产生全球环境问题的深刻根源。在环境经济学中被广泛采用的显示偏好或明示偏好等非市场价值导出方法尽管可以估计环境的经济价值,但这些方法仍以新古典经济学的一元价值论为基础,忽视了环境物品的价值多元性和不可估价性。近年来在环境伦理领域兴起的字典式偏好可以较好地描述环境多元价值,反映环境物品具有伦理属性、公共属性和政治属性。相对于新古典经济学的福利最大化和利益补偿原则而言,商议是一种可以发现和容纳环境多元价值的机制,也是现代市民社会解决环境争议的重要途径之一。     

The transition to a sustainable society: a new social contract

This paper explores issues that are central to ecological economics. In spite of a substantial body of research and other literature that has appeared in recent decades on transition, and countless other efforts, no progress has been made to halt the increase in global warming, global emissions, rampant population growth, or several hundred other critical planet sustainability indicators including global species extinction. The opposite is true. Consumption has escalated and it is poised to double and, with it, planetary decay has followed closely. The aim of this work is to introduce a pragmatic solution and the economics mechanisms solidly rooted in science, in the laws of conservation of mass and energy, and in environmental and ecological sustainability that are necessary to overcome the tremendous forces of social, political, and economic resistance to major change. To advance towards a sustainable civilization, adopting a holistic approach with those underlying principles in all aspects of human activity, among others economy, finance, industry, commerce, engineering, politics, architecture, and education, is both lacking and fundamentally required. A short review of the state-of-the-art of the science on the critical status of the planet’s resources and its life-supporting systems is presented, as well as a brief catalog of the seminal works of the science that gave rise to its metrics and established early on the groundwork for the understanding of the degree of sustainability of the planet. We present the argument why past and current schemes of human economics, organization, culture, and politics cannot achieve anything else, but complete and utter failure under their own underlying precepts. A rigorous and disciplined process on how to overcome and avoid the precipitous decline and collapse of the environmental and planetary biosystems on which all life depends, including human life, and a new view towards the world and the universe we all have no choice but to live in, are also offered.     

Structuring sustainability science

It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this article, we propose a research agenda that advances the methodological and theoretical understanding of what SS can be, how it can be pursued and what it can contribute. The key focus is on knowledge structuring. For that purpose, we designed a generic research platform organised as a three-dimensional matrix comprising three components: core themes (scientific understanding, sustainability goals, sustainability pathways); cross-cutting critical and problem-solving approaches; and any combination of the sustainability challenges above. As an example, we insert four sustainability challenges into the matrix (biodiversity loss, climate change, land use changes, water scarcity). Based on the matrix with the four challenges, we discuss three issues for advancing theory and methodology in SS: how new synergies across natural and social sciences can be created; how integrated theories for understanding and responding to complex sustainability issues can be developed; and how theories and concepts in economics, gender studies, geography, political science and sociology can be applied in SS. The generic research platform serves to structure and create new knowledge in SS and is a tool for exploring any set of sustainability challenges. The combined critical and problem-solving approach is essential.     

污染-经济时间弹性概念、方法与应用

环境污染随着经济发展的进程不断变化.为更加全面、准确地描述环境污染与经济发展的关系,本文将"弹性"分析方法应用于描述环境污染指标与经济发展指标之间的关系,提出"污染-经济时间弹性"概念,即一个国家或地区环境污染指标的年际变化率与相应的该国家或地区经济指标年际变化率的比值.文章进而分析了PETE的环境经济学含义及其计算方法.指标PETE能够用来描述一个国家或地区经济发展的清洁程度, 通常情况下, 较低的PETE值意味着较为清洁的增长方式, 而较高的PETE值则多与粗放和非清洁的增长方式相联系; 利用PETE还可以对空间(国家,地区)上和行业间的经济增长方式进行比较.文章最后通过1999-2008年中国环境污染指标(全社会主要污染物SO2、COD和烟尘排放量)数据和相应时间段的经济发展指标(GDP)数据, 计算中国全社会主要污染物排放与经济发展的"污染-经济时间弹性(PETE)", 发现该指标确能反映"经济发展的环境效率"的动态变化, 即为着获得一定的经济发展速度所付出环境代价之动态变化情状,验证了PETE概念和方法的科学性和实用性.PETE概念和方法的提出,为环境-经济分析提供了新的分析指标和工具.
