Effectiveness of EMAS: A case study of Polish organisations registered under EMAS

Balanced economic growth in line with environmental care is one of the greatest challenges facing the world nowadays. Entrepreneurs' interest in sustainable production schemes, including Environmental Management Systems (EMS), becomes an important part of many strategies and a frequent requirement of environmentally aware societies. Despite this, the number of organisations registered under the Eco-management and Audit Scheme (EMAS) decreased, while the implementation of EMS based on ISO 14001 continues to be popular. Many organisations registered in the EMAS scheme do not renew their registration; therefore, it is important to analyse the effectiveness of this environmental management tool as it should support sustainable development. This paper includes the results of research on EMAS registered organisations in Poland. The purpose of the study was to evaluate the effectiveness of the EMAS based on analysis of (1) the degree of environmental objectives implementation, (2) core environmental performance indicators, and (3) the correlation between establishing environmental objectives and results of environmental indicators in specific areas. The study involves an analysis of secondary data based on organisations' environmental statements published by the EMAS competent body. The findings suggest that there is no linear relationship between the time the EMAS is implemented and its effectiveness and that there is a weak correlation between establishing environmental objectives and changes in environmental performance indicators. These results are unexpected and may be linked to numerous mistakes made by organisations during establishing their environmental objectives. The study results have an impact to the EMAS regulation and shall be considered during review of EMAS scheme and future revisions of EMAS regulatory requirements.     

Environmental benchmarks vs. ecological benchmarks for assessment and monitoring in Canada: Is there a difference?

Environmental benchmarks are widely used in Canadian environmental assessment as a standard against which to monitor air or water quality in response to human activities in the environment. Recent work in Canada has developed the concept of ecological benchmarks as a complement to environmental benchmarks. However, implementation of ecological benchmarks may be challenging. This paper presents an analogy between ecological benchmarks and the more commonly used environmental benchmarks, as an attempt to increase understanding and use of ecological benchmarks in resource management, assessment, and monitoring. Ecological benchmarks, and their corresponding indicators, will be challenging to identify and use. However, through the use of the principles of adaptive management, effective ecological indicators and benchmarks can be established. Although it is essential that ecological benchmarks are site-specific, the analogy and general principles outlined here are applicable to assessment and monitoring in any part of the world.     

Towards a green and fast production system: Integrating life cycle assessment and value stream mapping for decision making

Integrating environmental commitment to manufacturing concerns seems unavoidable towards a more sustainable conduct. In the contemporary scenario, Value Stream Mapping (VSM) has been bringing new perspectives into companies' economics, improving production performance, whereas Life Cycle Assessment (LCA) has been the most complete tool for environmental assessment. Therefore, the present study aims to propose a model based on the integration of LCA and VSM to improve environmental and manufacturing aspects of organizations, the LCA-VSM model. Possible spots for integration, overlaps between LCA and VSM and potential gains were identified. The LCA-VSM model provides a simple tool for prioritizing action measures to improve the environmental-economic performance, and unlike many existing methods, it encourages continuous improvement instead of a one-off approach. The company where a case study was conducted to test the LCA-VSM model is a manufacturer of tools and painting materials for the civil construction sector. The use of the proposed model guided actions that decreased from 5% to 15% of environmental impacts (across nine impact categories), and reduced both non-value adding (lead time went from 103.26 to 24.01 days) and value adding (cycle time went from 35.7 s to 33.75 s) time. The main contribution of this paper is providing a structured approach to a practical integration of LCA and VSM towards decision making, prioritizing action measures based on the following criteria: environmental preference, economic feasibility, and ease of implementation, aiding more eco-efficient practices.     

The combination of an Environmental Management System and Life Cycle Assessment at the territorial level

A framework to include a Life Cycle Assessment in the significance evaluation of the environmental aspects of an Environmental Management System has been studied for some industrial sectors, but there is a literature gap at the territorial level, where the indirect impact assessment is crucial. To overcome this criticality, our research proposes the Life Cycle Assessment as a framework to assess environmental aspects of public administration within an Environmental Management System applied at the territorial level. This research is structured in two parts: the design of a new methodological framework and the pilot application for an Italian municipality. The methodological framework designed supports Initial Environmental Analysis at the territorial level thanks to the results derived from the impact assessment phase. The pilot application in an Italian municipality EMAS registered demonstrates the applicability of the framework and its effectiveness in evaluating the environmental impact assessment for direct and indirect aspects. Through the discussion of the results, we underline the growing knowledge derived by this research in terms of the reproducibility and consistency of the criteria to define the significance of the direct and indirect environmental aspects for a local public administration.     

Reflecting on,and revising,international best practice principles for EIA follow-up

Follow-up is a vital component of Environmental Impact Assessment (EIA), being essential for understanding assessment outcomes. Long-standing international best practice principles for EIA follow-up are reviewed, and revisions proposed, based on workshops with academics and practitioners, literature review and self-reflection. The proposed revision of EIA follow-up principles will feature an introduction with a simple definition and explanation of objectives for follow-up, and 15 principles. The revised principles address: objective; context; early establishment; project life-cycle; transparency; accessibility; accountability; performance criteria provision; enforcement; learning; adaptive environmental management; flexible or adaptive approach; tiering; cumulative effects and overall performance evaluation. Through publishing this proposal, it is hoped to simultaneously inform or inspire EIA practitioners to enhance their own follow-up knowledge and practices, and to seek input for further refinements that might lead to a revised set of international best practice principles for EIA follow-up.     

An environmental risk assessment framework for enhanced oil recovery solutions from offshore oil and gas industry

Environmental risk assessments are necessary to understand the risk associated with enhanced oil recovery (EOR) solutions and to provide decision support for choosing the best technology and implementing risk-reducing measures. This study presents a review of potentially relevant environmental/ecological risk assessment (ERA) guidelines and, based on this review, proposes an initial suggestion of an ERA framework for understanding the environmental impacts from EOR solutions. We first shortlist the important elements necessary for conducting an ERA of EOR solutions from the selected guidelines. These elements are then used to build the suggested ERA framework for produced water discharges, drilling discharges and emissions to air from EOR solutions, which is the primary objective of the present study. Furthermore, the emphasis is placed on identifying the knowledge gaps that exist for conducting ERA of EOR processes. In order to link the framework with the current best environmental practices, a review of environmental policies applicable to the marine environment around the European Union (EU) was conducted. Finally, some major challenges in the application of ERA methods for novel EOR technologies, i.e. uncertainties in the ERA due to lack of data and aggregation of risk from different environmental impacts, are discussed in detail. The frameworks suggested in this study should be possible to use by relevant stakeholders to assess environmental risk from enhanced oil recovery solutions.     

Sustainable natural resource management and environmental assessment in the Salt Lake (Tuz Golu) Specially Protected Area

The Salt Lake Specially Protected Area is a unique ecosystem for both agricultural activities and natural life in Turkey. In the present study, an attempt was made to develop a conceptual land use strategy and methodology, taking into account ecological factors for regional development in the Salt Lake Specially Protected Area. A detailed Geographic Information System (GIS) analysis was done to create a comprehensive database including land use, land suitability, and environmental factors (soil, climate, water quality, fertilizing status, and heavy metal and pesticide pollution). The results of the land suitability survey for agricultural use showed that, while 62.6% of the study area soils were classified as best and relatively good, about 15% were classified as problematic and restricted lands, only 22.2% of the study area soils were not suitable for agricultural uses. However, this is not enough to derive maximum benefit with minimum degradation. Therefore, environmental factors and ecological conditions were combined to support this aim and to protect the ecosystem. Excessive irrigation practices, fertilizer and pesticide application, and incorrect management practices all accelerate salinization and degradation. In addition to this, it was found that a multi-layer GIS analysis made it easy to develop a framework for optimum land use and could increase the production yield preserving the environmental conditions. Finally, alternative management and crop patterns were undertaken to sustain this unique ecosystem, considering water, soil, climate, land use characteristics, and to provide guidance for planners or decision makers.

Reference materials for the monitoring of the aquatic environment--a review with special emphasis on organic priority pollutants

During recent years, the awareness of quality assurance and quality control in environmental analyses has constantly increased, especially due to the implementation of new guidelines and regulations at both the national and international level. Achieving comparable results by using certified reference materials is one of the primary concerns of the scientific community. As a result, there is a growing demand for certified reference materials to cover different matrices and pollutants. Moreover, these CRMs should be in close relationship to the determinants and target concentrations required by environmental bodies and European Directives as well. Supplementary information to this paper presents an inventory of reference materials available on the market from different suppliers against the priority pollutants listed in the Water Framework Directive. These CRMs cover matrices such as water, sediment and biota. The use of CRMs in relationship to appropriate analytical methods and relevant determinants is discussed and the need for matrix-CRMs, particularly for organic pollutants is emphasised. The use of proficiency testing schemes as an alternative for the lack of appropriate CRMs and future trends in the production of CRMs within the BCR framework are also discussed.     

ISO 14001认证中环境监测的问题与对策

在ISO 14001：2004（环境管理体系一要求及使用指南》认证过程中,认证机构需要通过环境监测判断申请认证组织的污染物排放是否达到环境标准和总量控制指标的要求,指出在ISO 14001认证中的环境监测,存在着监测项目不充分、监测过程偏离技术规范、监测机构没有相应资质和审核员缺乏环境科学与技术知识等问题,以及认证机构不能有效利用环境监测这一手段评价申请认证组织的环境行为,提出了应充分识别环境监测要求、严格把好环境监测机构资质关和提高审核员环境科学与技术素质的一系列对策。     

Emissions from gas processing platforms to the atmosphere-case studies versus benchmarks

This study compares oil and gas industry benchmark non-methane volatile organic compounds emission data with predicted and reported emissions from a number of recent case studies. Specifically, we contrast predicted emissions from the Tamar and Leviathan processing platforms in the Eastern Mediterranean with actual emissions where available, and with a compilation of industry benchmarks. This work reveals a series of flaws in the adopted EIA practices in the case studies discussed, starting from the emissions model that grossly underestimates intermittent NMVOC and benzene emissions relative to available data from other sites, and the unrealistic assumption of a constant and uniform emission profile in contrast to real world emission scenarios that are characterized by discrete large emission events. Furthermore, the dispersion model used in the EIAs as part of the request for a business (emissions) permit has a number of significant failings, including the use of an unsuitable model, use of over-simplistic meteorological inputs, and lack of consideration of critical dispersion phenomena. This study highlights the need to rethink the currently used environmental impact assessment and atmospheric permit request methodologies in the oil and gas industry, which rely on unrealistic uniform emission models.     

A Multiple Criteria Decision Analysis Model Based on ELECTRE TRI-C for Erosion Risk Assessment in Agricultural Areas

This paper deals with a real-world decision-aiding problem for zoning the risk of erosion, total suspended solids emissions, and ecological consequences of their transfers towards the streams. One of these consequences is the decrease of fishes into the streams in agricultural watersheds, because of the clogging of spawning areas. Given the multiple criteria nature of the problem, the originality of our research is to adapt a new decision-aiding sorting method, ELECTRE TRI-C, for identifying risk zones in rural areas, where measures must be taken. The developed model was applied in a small watershed (Low Normandy, France) where the objective was to assess the most appropriate intervention for protecting the reproduction habitat of the salmonid fishes. Agricultural parcels were evaluated on multiple criteria for grouping them into four risk categories, which are related to risk levels as well as priorities on the improvement works. The decision-aiding sorting model is co-constructed, within a constructive approach, through an interaction process between decision-aiding analysts, environmental experts, and local actors for improving transparency and communication on the results. This model is linked with a geographical information system (GIS) for assessing a set of criteria and the visualization of the farming parcels along with their type of intervention they should be submitted to best practices. The assignment results were validated by the environmental experts. These results have a strong impact on the agricultural practices of the farmers into the watersheds. The model proposed in this paper can be considered as a useful decision aid tool in any regions for implementing public agricultural and environmental policies for protecting the ecological areas.     

Selective extraction of persistent organic pollutants from environmental matrices

An attempt is made to determine the bioavailability of persistent organic pollutants (POP's) in environmental matrices. The approach is based on the use of the Hildebrand Solubility Parameter, and its individual parameters of hydrogen bonding, dispersion and polarity to select weak and strong solvents to extract POP's from soil matrices. The approach has been applied to both spiked soils and certified reference materials. Initial results indicate that it is possible to fractionate POP's from soil matrices based on their ability to be extracted from soil by particular solvents.     

Long-term environmental monitoring for assessment of change: measurement inconsistencies over time and potential solutions

The importance of long-term environmental monitoring and research for detecting and understanding changes in ecosystems and human impacts on natural systems is widely acknowledged. Over the last decades, a number of critical components for successful long-term monitoring have been identified. One basic component is quality assurance/quality control protocols to ensure consistency and comparability of data. In Norway, the authorities require environmental monitoring of the impacts of the offshore petroleum industry on the Norwegian continental shelf, and in 1996, a large-scale regional environmental monitoring program was established. As a case study, we used a sub-set of data from this monitoring to explore concepts regarding best practices for long-term environmental monitoring. Specifically, we examined data from physical and chemical sediment samples and benthic macroinvertebrate assemblages from 11 stations from six sampling occasions during the period 1996–2011. Despite the established quality assessment and quality control protocols for this monitoring program, we identified several data challenges, such as missing values and outliers, discrepancies in variable and station names, changes in procedures without calibration, and different taxonomic resolution. Furthermore, we show that the use of different laboratories over time makes it difficult to draw conclusions with regard to some of the observed changes. We offer recommendations to facilitate comparison of data over time. We also present a new procedure to handle different taxonomic resolution, so valuable historical data is not discarded. These topics have a broader relevance and application than for our case study.     

The Swedish System for Quality Assessment of Agricultural Soils

Soil quality assessment is based on the concept of soilfunctions. The performances of three soil functions, cropproduction, biological decomposition and matter exchange withthe atmosphere and groundwater, are used as quality criteria.Soil properties that can be used as indicators for the degreeof functional performance were identified. Each soil propertyselected was graded into five classes – from best (class 1) toworst (class 5). Grading was based biological on boundaryconditions as well as on statistical distribution. The systemoutlined can be used to interpret the quality state ofagricultural soils, provides for a relative comparison betweensoils, and may be helpful in an environmental monitoringprogram to assess trends in data.     

Pesticide Use and Residual Occurrence in Thailand

This paper addresses pesticide use, environmental problems, and regulations in Thailand. Annually, Thailand imports several thousand metric tons of herbicides, fungicides, and insecticides. Agricultural goods are among the country's primary exports. Over the past decade, Thailand's agricultural sector has shifted from labor- to machine-intensive farming practices. Pressures to sustain high crop yields have led to heavy usage of pesticides. Residues, especially organochlorine and organophosphate compounds, have been found in soil, water, and agricultural products throughout the country. Occupational exposure and suicide are the main causes of pesticide poisoning to Thailand's residents. Recognizing the growing problem, Thailand's government has enacted environmental laws and education programs aimed at minimizing adverse effects of pesticides.     

A simple method to identify areas of environmental risk due to manure application

The management of swine manure is becoming an important environmental issue in Chile. One option for the final disposal of manure is to use it as a biofertilizer, but this practice could impact the surrounding environment. To assess the potential environmental impacts of the use of swine manure as a biofertilizer, we propose a method to identify zones of environmental risk through indices. The method considers two processes: nutrient runoff and solute leaching, and uses available information about soils, crops and management practices (irrigation, fertilization, and rotation). We applied the method to qualitatively assess the environmental risk associated with the use of swine manure as a biofertilizer in an 8,000-pig farm located in Central Chile. Results showed that the farm has a moderate environmental risk, but some specific locations have high environmental risks, especially those associated with impacts on areas surrounding water resources. This information could assist the definition of better farm-level management practices, as well as the preservation of riparian vegetation acting as buffer strips. The main advantage of our approach is that it combines qualitative and quantitative information, including particular situations or field features based on expert knowledge. The method is flexible, simple, and can be easily extended or adapted to other processes.     

Disasters can happen to anybody: The case of Korea

In Korea, there is a pervasive feeling of invincibility to the point that people and organizations do not believe that disasters can strike them. This has impact on the level of preparedness for disasters. This study aims to delve into how Korea has to change its governmental policies/practices with some private partners' efforts to mitigate disaster risks. A case study was utilized as the major methodology by comparing exclusive management with inclusive management. These two approaches have been comparatively analyzed via four variables, namely the central government, the local governments, the incident commander, and other stakeholders. The major finding is that Korea's practices and policies have to evolve from the current exclusive management into future-oriented inclusive management. Moreover, the importance of communication, cooperation, collaboration, and multi-discipline coordination is discussed. Additionally, the problem of reductionism and equal participation among all stakeholders, as well as the resistance from vested interests, are recognized and elaborated for Korea and the international community.     

A mixed model-based Johnson's relative weights for eco-efficiency assessment: The case for global food consumption

Eco-efficiency composite indicators are widely accepted as the ratio of environmental impact to created economic value. These indicators are realistic measures for assessing sustainability performance considering the economy and environment. The weights reflect the importance of indicators to the aggregated environmental impacts. Estimating the relative weight of indicators is highly subjective, and therefore the search for a single unique weighting method has been going on for years. The regression-based weights are one of the most recent trends in sustainability modeling. Since these methods are designed initially to investigate the impact of multiple variables on a response variable rather than to estimate weights, some drawbacks are associated with their potential to provide proper weights. This paper presents a novel weighting approach integrating linear mixed-effect models with Johnson's relative weights to address these drawbacks and provide meaningful relative weights for eco-efficiency composite indicators. The proposed approach's operational and computational procedures are illustrated using a real example, and the eco-efficiency of food consumption of 38 countries is estimated for the period between 1990 and 2012 using a consumption-based sustainability accounting method. The findings have shown that energy use and GHG indicators are the most critical contributor to global food consumption's environmental impacts. The country-based eco-efficiency performance in this work has shown that China, India, and Russia are located in the low eco-efficiency score class. The Spatio-temporal analysis downgraded the geographical location's significance on the trends of eco-efficiency behavior in time and space. On the other hand, it revealed the different types of emerging hot spots over the world.
