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.     

Global trends in gold mining: Towards quantifying environmental and resource sustainability

In recent years, due to public concern over perceived and actual environmental impacts, the global mining industry has been moving towards a more sustainable framework. For gold mining, there are a number of fundamental issues with regard to assessing sustainability. Commonly perceived as a finite and non-renewable resource, long-term gold production trends include declining ore grades and increasing solid wastes (tailings, waste rock) and open cut mining. Conversely, core sustainability issues include water, energy and chemical consumption and pollutant emissions—also known as ‘resource intensity’. It is important to recognise the links between gold production trends and resource intensity, as this is critical for understanding future sustainability challenges. This paper links data sets on historic gold mining production trends with emerging sustainability reporting to estimate resource intensity, demonstrating the sensitivity of ore grade for gold production and sustainability. Final judgement of the sustainability of gold mining must take account of the sensitivity of the ore grade in the resource intensity of gold production. This has implications for environmental policy and sustainability reporting in the gold mining sector.     

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.

Environmental management auditing: When credentials count!

We all know that the process of driving a car is not as simple as turning a key in the ignition and moving. When you want to drive a car, you take a written test to show your knowledge of the rules of the road. You learn to operate a vehicle (remember the operating difference between a standard shift and an automatic?) and then how to operate that vehicle in moving traffic. After you have gained competence in vehicle operation, you take a “hands-on” driving test to prove to an independent third party (the State) that you know what you are doing. Then, if you do know, you are issued a license, subject to renewal and perhaps retesting at some later point in time. Your license has become your credential to operate. It implies a certain minimum level of knowledge and experience. Should environmental auditing be any different? This article considers the application of a uniform standard for environmental auditor qualification. With an emphasis on ISO 14001¹ and auditing of environmental management systems, it discusses:

• the evolution of environmental auditing;
• established environmental auditor qualification processes;
• limitations of compliance auditing; and
• characteristics of a good auditor.

     

Greenhouse gas emissions from conventional, agri-environmental scheme, and organic Irish suckler-beef units

The problems of overproduction within the European Union countries and the environmental impact of agriculture have lead to the introduction of schemes that aim to reduce both. Beef (Bos taurus) production forms a large component of the Irish agricultural industry and accounts for more than one quarter of agricultural economic output. Recently, the European CAP (Common Agricultural Policy) has been re-evaluated to include supplementary measures that encompass the environmental role of agriculture rather than just the production role. A life cycle assessment (LCA) method was adopted to estimate emissions per kilogram of CO2 equivalent per kilogram of live weight (LW) leaving the farm gate per annum (kg CO2 kg(-1) LW yr(-1)) and per hectare (kg CO2 ha(-1) yr(-1)). Fifteen units engaged in suckler-beef production (five conventional, five in an Irish agri-environmental scheme, and five organic units) were evaluated for emissions per unit product and area. The average emissions from the conventional units were 13.0 kg CO2 kg(-1) LW yr(-1), from the agri-environmental scheme units 12.2 kg CO2 kg(-1) LW yr(-1), and from the organic units 11.1 kg CO2 kg LW yr(-1). The average emissions per unit area from the conventional units was 5346 kg CO2 ha(-1) yr(-1), from the agri-environmental scheme units 4372 kg CO2 ha(-1) yr(-1), and from the organic units 2302 kg CO2 ha(-1) yr(-1). Results indicated that moving toward extensive production could reduce emissions per unit product and area but live weight production per hectare would be reduced.     

关于环境影响评价中清洁生产分析的几点看法

环境影响评价中纳入清洁生产概念，设置专题章节对建设项目进行清洁生产分析，有利于提高环评质量。但环境影响评价与清洁生产各自有相对成熟的理论体系和方法，使环评中的清洁生产分析存在一定的局限性。笔者根据多年工作实践，着重对其局限性产生的原因进行了分析，并提出了提高清洁生产分析质量的途径。     

清洁生产纳入环境影响评价的意义

当前的环境影响评价在某种程度上更侧重于环境的末端治理,无法将污染控制与生产过程控制密切结合,资源和能源不能在生产过程中得到充分利用.而清洁生产在这方面却有着独特的特点和优势.根据清洁生产与环境影响评价的内在联系,尽快地将清洁生产纳入环境影响评价是具有重要意义的,清洁生产应该成为环境影响评价报告撰写中的重要内容.     

Maintaining your EMS: The stages of EMS development

Registering to ISO 14001 doesn't mean you're forever green. If you want an environmental management system (EMS) to keep moving your organization forward to improved environmental and business performance, you need to maintain and refine it. The first step toward doing so is understanding the stages that each EMS goes through on its way to full business integration. © 2000 John Wiley & Sons, Inc.

Indirect and Avoided Environmental Consequences in Project Evaluation

The paper focuses on indirect environmental consequences, namely the environmental consequences of the production of project inputs. In addition, we introduce the term 'avoided environmental consequences', i.e. the environmental consequences associated with diversion of production factors from alternative use. The former are always relevant, while the avoided consequences are only relevant in cases involving fully-employed production factors that would otherwise be used in production. The inclusion of indirect and avoided environmental consequences may considerably affect the outcome of traditional project evaluation. In this paper it is suggested how the indirect and avoided environmental consequences may be described using the input-output system in combination with environmental coefficients.

Environmental assessment of packaging: Sense and sensibility

The functions of packaging are derived from product requirements, thus for insight into the environmental effects of packaging the actual combination of product and package has to be evaluated along the production and distribution system. This extension to all related environmental aspects adds realism to the environmental analysis and provides guidance for design while preventing a too detailed investigation of parts of the production system. This approach is contrary to current environmental studies where packaging is always treated as an independent object, neglecting the more important environmental effects of the product that are influenced by packaging. The general analysis and quantification stages for this approach are described, and the currently available methods for the assessment of environmental effects are reviewed. To limit the workload involved in an environmental assessment, a step-by-step analysis and the use of feedback is recommended. First the dominant environmental effects of a particular product and its production and distribution are estimated. Then, on the basis of these preliminary results, the appropriate system boundaries are chosen and the need for further or more detailed environmental analysis is determined. For typical food and drink applications, the effect of different system boundaries on the outcome of environmental assessments and the advantage of the step-by-step analysis of the food supply system is shown. It appears that, depending on the consumer group, different advice for reduction of environmental effects has to be given. Furthermore, because of interrelated environmental effects of the food supply system, the continuing quest for more detailed and accurate analysis of the package components is not necessary for improved management of the environmental effects of packaging.     

Transhumance in Central Anatolia: A Resilient Interdependence Between Biological and Cultural Diversity

Transhumance is a resource efficient means of livestock production by seasonally moving grazing animals to utilize pastures between varying ecological zones. This article investigated the interrelationship between the environmental services the transhumant provides whilst maintaining its cultural heritage and theorized what the cultural and environmental impacts would be if the practice of transhumance were to vanish. The authors interviewed 45 transhumant families during their 2015 seasonal migration through the Taurus Mountains and in their settled tent sites in Central Anatolia. The interview topics related to geography of the region, migration routes, natural resource constraints and opportunities, animal husbandry, grazing strategies and their income sources. By practicing agro-ecological principles over millennia, the research showed that the transhumant has helped shape a complex mosaic of habitats in one of Mediterranean’s most interesting ecosystems. The mobile pastoralist with conservation and natural resource management skills over a long period has reduced erosion control, improved soil quality and deterred the likelihood of forest fires, whilst weaving a resilient social web. The survey also indicated a clear link between social and ecological resilience emphasizing that sustainable development relies on the interconnectedness between biological and cultural diversity. The study recommends special provisions be made by the Turkish government for the educational needs for the children of the transhumant, provide initiatives for improved trading of their produce, introduce law enforcement for oppressive behavior against them and finally support the pastoralists to attain world heritage listing as a unique and an irreplaceable culture for the future welfare of humankind.     

A GIS-based approach for the screening assessment of noise and vibration impacts from transit projects

Urban transportation projects are essential in increasing the efficiency of moving people and goods within a city, and between cities. Environmental impacts from such projects must be evaluated and mitigated, as applicable. Spatial modeling is a valuable tool for quantifying the potential level of environmental consequences within the context of an environmental impact assessment (EIA) study. This paper presents a GIS-based tool for the assessment of airborne-noise and ground-borne vibration from public transit systems, and its application to an actual project. The tool is based on the US Federal Transit Administration's (FTA) approach, and incorporates spatial information, satellite imaging, geostatistical modeling, and software programming. The tool is applied on a case study of initial environmental evaluation of a light rail transit project in an urban city in the Middle East, to evaluate alternative layouts. The tool readily allowed the alternative evaluation and the results were used as input to a multi-criteria analytic framework.

In the midst of change

It is characteristic to be in the midst of change and not to recognize it. In retrospect 1970–72 at Clark University presaged a successful universalization of environmental perception, but it was a high point rather than a beginning in pursuit of the higher aspirations of the then-fledgling field. These aspirations—to solve practical problems, to develop a common methodology, to bridge the disciplines, and to develop or revise a theory—have never been fully realized. Widely accepted today, environmental perception and behavior mirrors the everyday differences within and between disciplines and thus is divided by theoretical ideology, substantive focus and views as to what constitutes data. As with the individual disciplines, I have successfully integrated environmental perception into my own work, moving it from the exceptional to the everyday, and with some regret, from the magic of 1970–72 to the science of today.

A review of studies applying environmental impact assessment methods on fruit production systems

Although many aspects of environmental accounting methodologies in food production have already been investigated, the application of environmental indicators in the fruit sector is still rare and no consensus can be found on the preferred method. On the contrary, widely diverging approaches have been taken to several aspects of the analyses, such as data collection, handling of scaling issues, and goal and scope definition. This paper reviews studies assessing the sustainability or environmental impacts of fruit production under different conditions and identifies aspects of fruit production that are of environmental importance. Four environmental assessment methods which may be applied to assess fruit production systems are evaluated, namely Life Cycle Assessment, Ecological Footprint Analysis, Emergy Analysis and Energy Balance. In the 22 peer-reviewed journal articles and two conference articles applying one of these methods in the fruit sector that were included in this review, a total of 26 applications of environmental impact assessment methods are described. These applications differ concerning e.g. overall objective, set of environmental issues considered, definition of system boundaries and calculation algorithms. Due to the relatively high variability in study cases and approaches, it was not possible to identify any one method as being better than the others. However, remarks on methodologies and suggestions for standardisation are given and the environmental burdens of fruit systems are highlighted.     

Environmental management in mining and mineral processing in developing countries

This paper analyses some of the social, political and economic dimensions of the environmental behaviour of mining enterprises and governments in the context of evolving regulation, growing public concern and technological innovation. Contrary to the belief that a trade-off exists between production costs and environmental costs, which presupposes a static technology, new generations of technology offer improved economic and environmental efficiency. Technical change is therefore reducing both production and environmental costs. Because most planned mines and available reserves are in developing countries, situations may develop whereby technical change reduces that trade-off for them.
