An LCA-based environmental impact assessment model for regulatory planning

Assessing the environmental impact (EI) of regulatory planning (a lower tier in the Chinese urban planning system) has significant implications for improving the environmental performance of the future built environment. Current environmental impact assessments generally focus on microscale and macroscale, while mesoscale studies at region level are lacking. To fill this gap, this paper proposes an LCA-based environmental impact assessment model for regulatory planning, which focuses on embodied EI of urban construction and operational EI associated with the operation of the built environment. To ensure the regulatory plans both meet the environmental limits and fit well with environmental policy requirements, this paper also presents a new impact analysis method by integrating environmental carrying capacity analysis and distance to target method. The Statutory Plan of Shenzhen Futian Free Trade Zone 03-T2 is used as a case study to test and demonstrate the applying process and functions of the proposed method. Results indicate that the proposed model can effectively quantify the future environmental impact associated with a regional development plan, and can potentially be used as a tool for urban administrators to make decisions on regulatory planning revision and provide references for environmental management.     

Planning theories and environmental impact assessment

The limited and sporadic interaction between EIA and planning theory has meant that EIA has largely failed to benefit from planning theory insights and lessons. Obstacles and dilemmas already encountered and addressed in planning theory are still hampering EIA theory building and practice. An overview of the characteristics, strengths, and limitations of five major planning theories—rationalism, pragmatism, socio-ecological idealism (SEI), political-economic mobilization (PEM), and communications and collaboration (CC) is presented in an effort to ameliorate this problem. EIA parallels to each planning theory and lessons for EIA are identified. Also addressed are the application of planning theories to different context types, overlaps, interconnections and middle ground concepts among theories, the integration of values, ethics, and postmodern perspectives and the potential to construct composite theories.     

Computer-aided rapid environmental impact assessment

Environmental impact assessment of a project attempts to bring about compatibility between ecology and economics. A computer-aided, quantitative and rapid methodology for environmental impact assessment is presented in this paper. The cost of abatement of deleterious environmental impacts is one of the factors used to identify the best project option from environmental and cost considerations. The methodology is based on the three basic steps of environmental impact assessment vis-à-vis identification, prediction, and evaluation. Several models and predictors for different environmental components are incorporated in the computer program. An evaluation method is presented based on mathematical functions for value function graphs for different aesthetic, environmental, and health risks.     

The environmental impact statement comes to Israel: An initial assessment

Despite obstacles inherent in the structure of government and the lack of a strong national constituency, environmental impact assessment became a policy-making element in the government of Israel in 1982. The Environmental Protection Service formed in 1973 now needs to develop strategies to promote environmental awareness and environmentally informed decision making among the public, private and public developers, and within the Ministry of the Interior.     

Setting boundaries of participation in environmental impact assessment

Public participation processes are touted as an effective way to increase the capacity and legitimacy of environmental assessment and the regulatory process that rely on them. Recent changes to the Canadian environmental assessment process narrowed the criteria for who can participate in environmental assessments from any who were interested to those who were most directly affected. This article examines the potential consequences of this change by exploring other areas of Canadian regulatory law where a similar directed affected test has been applied. This new standard risks institutionalizing the long-understood representational bias confronted by more diffuse interest like environmental protection. Restricting participation to the “directly affected” is far too narrow a test for processes like environmental assessment that are designed to determine the public interest.     

Evaluation of the environmental impact assessment system in Iran

EIA in Iran was formally introduced in 1994, but to date little EIA-related research has been undertaken in the country. In this paper, the authors provide an evaluation of the Iranian EIA system, focusing on EIA legislation, administration and process. Data was collected on the basis of a literature review, document analysis and semi-structured interviews. This involved some translation from Persian into English. Evaluation of the findings indicate that Iran has adopted the democratic tools of EIA and SEA, which considering its political context is encouraging. However, currently the Iranian EIA system does suffer from weaknesses such as inadequate screening and scoping, lack of alternative consideration, public participation, EIA implementation and follow-up. The paper proposes some initial recommendations based on international experiences and sets out the direction for future research.     

Underwater noise modelling for environmental impact assessment

Assessment of underwater noise is increasingly required by regulators of development projects in marine and freshwater habitats, and noise pollution can be a constraining factor in the consenting process. Noise levels arising from the proposed activity are modelled and the potential impact on species of interest within the affected area is then evaluated. Although there is considerable uncertainty in the relationship between noise levels and impacts on aquatic species, the science underlying noise modelling is well understood. Nevertheless, many environmental impact assessments (EIAs) do not reflect best practice, and stakeholders and decision makers in the EIA process are often unfamiliar with the concepts and terminology that are integral to interpreting noise exposure predictions. In this paper, we review the process of underwater noise modelling and explore the factors affecting predictions of noise exposure. Finally, we illustrate the consequences of errors and uncertainties in noise modelling, and discuss future research needs to reduce uncertainty in noise assessments.     

Integrating SDGs in environmental assessment: Unfolding SDG functions in emerging practices

Debates concerning the relation between Sustainable Development Goals (SDGs) and environmental assessment (EA) have long suggested their integration in some form. The purpose of this paper is to go beyond conceptual debates to explore practices of environmental impact assessment and strategic environmental assessment in terms of how they change in response to the Agenda 2030. A thorough web search for EA reports integrating SDGs resulted in 45 cases from five continents, which were then analyzed using a framework on levels of integration to examine and reflect on practice. The results show that in the majority of reports, SDGs are merely mentioned with no further function, that there is a trend towards focusing on positive impacts and that there is a high variation in how contributions to SDGs are assessed and displayed. The paper concludes by identifying key directions for further research, such as ways to further understand practices and to close the gap between theoretical considerations and EA practice.     

Role of and challenges to environmental impact assessment proponents in Pakistan

This study identified the role of and challenges faced by Environmental Impact Assessment (EIA) proponents in Punjab, Pakistan. Expected roles of proponents in EIA were taken from regulations, legislation and guidelines. The comments of consultants, Environmental Protection Agency (EPA) and non-governmental organisations (NGOs) regarding the role played by proponents were extracted from literature and used for evaluation. To identify the challenges of proponents in each step of the EIA, 40 semi-structured interviews were conducted with private and government proponents in Punjab. Oftentimes, projects start prior to obtaining an environmental approval. Proper scoping is seldom conducted. Stakeholder involvement in EIA is limited. Proponents sometimes do not share complete project information with consultants, which compromises the report quality and timely decision making. Moreover, some proponents attempt to influence the review and decision making and do not ensure compliance to approval conditions except for few multinationals. The key challenge highlighted by proponents was the discrimination on part of the EPA between private and government projects. Other challenges included lack of professionalism of some consultants and delayed and non-transparent decision making. Although regional in scope, the results of the study hold importance for EIA systems worldwide particularly in countries with similar economic systems who are facing a trade-off between economic growth and environmental sustainability.     

Consideration of climate change on environmental impact assessment in Spain

Most of the projects subject to environmental impact assessment (EIA) are closely related to climate change, as they contribute to or are affected by it. The growing certainty about climate change and its impacts makes its consideration an essential part of the EIA process, as well as in strategic environmental assessment (SEA).This paper examines how climate change (CC) has been taken into account in EIA in Spain through the analysis of 1713 environmental records of decision (RODs) of projects submitted for EIA. In 2013 Spain approved one of the most advanced laws in terms of CC consideration in environmental assessment, although it had not yet accumulated extensive practice on the issue. This contrasts with the situation of countries like Canada or the USA, which have a significant body of experience without specific legal requirements.Only 14% of the RODs analysed included references to CC, and in more than half of the cases it was a mere citation. Thermal power plants, which are subject to specific GHG regulations, show the highest consideration, while transport infrastructures, which are important contributors to CC, show a very low consideration. Almost all the references are related to their contribution to CC, while consideration of the effects of CC is minimal.The increasingly common incorporation of CC into SEA, should not imply its exclusion from EIA, because both processes have different aims and uses. Including the obligation to consider CC in the EIA regulations is highly desirable, but probably not enough without other measures, such as practical guidance, training and motivational programmes for practitioners and evaluators. But even these actions cannot ensure effective and adequate assessments of CC. Probably more resources should be spent on creating greater awareness in all the agents involved in EIA.     

The Australian government's experience with environmental impact assessment

This article reviews the implementation of the Commonwealth government's environmental impact assessment (EIA) legislation over its 12-year history. The Whitlam Labor government initially sought to implement the EIA requirement widely. However, resistance by the states and by sections of the bureaucracy combined with the policies of the ensuing Fraser Liberal-National Country Party government to limit implementation. The number of EISs produced has been low, and EIA has not yet been fully accepted as a routine part of government decision making. The article examines the factors that have contributed to this outcome, and proposes some changes to strengthen the EIA process.
