  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Compliance Trends in 2017: what to expect, how to prepare

    Looking back on 2016, it was without doubt a year of political upheaval and increased scrutiny on the environmental, social and human rights implications of government regulations, corporate practices and consumer habits. In 2017, these changes will fuel additional compliance considerations for corporate supply chains around the world. While the future is anything but certain, our regulatory ...

  • Environmental modelling for blue collars

    Model complexity and the ‘breakpoint of diminishing returns’; ‘physical’ vs. ‘conceptual’ modelling; the relevance and limits of the heuristic solutions; screening vs. analytical modelling; perceptions of uncertainties, calibration and sensitivity analysis; and the ‘ethics in modelling’ – are only a few issues outstanding in the volatile philosophy of the environmental modelling. Glossing on ...

  • Modelling trade and environmental linkages in China

    Interactions between trade and the environment have been studied extensively as a reaction to the pressure that the accelerated pace of globalisation has placed on environment and trade. Distinguishing itself from previous work, this study focuses on a modelling analysis of the interactions between trade and the environment in China. A non-linear simultaneous equation trade and environment model ...

  • Models of energy saving systems: the battlefield of environmental planning

    Traditionally, energy planning has been interpreted as planning for an appropriate energy supply system, based on a crude prognosis for the energy demand. Over the past couple of decades, however, the immense possibilities of regulating energy demand - and the benefits of doing it - have become increasingly recognised and also partly included in the planning. This paper first describes some ...

  • Atmospheric environmental impact assessment modelling in France

    The most widely accepted model of atmospheric dispersion for impact assessment in France is the Gaussian model of Doury. The Centre d'Etudes Atomiques (CEA) and Electricite de France (EDF) have developed their own software systems, which include several compatible or nested meteorological, trajectory, and dispersion codes. These systems are fitted to the various atmospheric scales from regional ...

  • Improved environmental multimedia modeling and its sensitivity analysis

    Modeling of multimedia environmental issues is extremely complex due to the intricacy of the systems with the consideration of many factors. In this study, an improved environmental multimedia modeling is developed and a number of testing problems related to it are examined and compared with each other with standard numerical and analytical methodologies. The results indicate the flux output of ...

  • Endogenous technology and environmental quality in economic models

    The debate on the relationship between the economy and the environment focuses on the question whether there is a trade-off between economic growth and environmental quality. In order to enable a quantification of this essentially empirical question, it is necessary to integrate the environment into economic models. This article considers the integration of the environment in models of economic ...

  • Understanding QSPR uncertainty in environmental fate modeling

    In cases where experimental data on chemical‐specific input parameters are lacking, chemical regulations allow the use of alternatives to testing, such as in silico predictions based on quantitative structure‐property relationships (QSPRs). Such predictions are often given as point estimates; however, little is known about to what extent uncertainties associated with QSPR predictions contribute ...

  • An Interactive Environmental Economy Model for Energy Cycle in Iran

    ABSTRACT The growing world economy calls for saving natural resources with sustainable development framework. This paper intends to look at the environment-energy interface (impacts on the environment stemming form the energy sector) and to propose measures for reducing this impact without trying to impede economic development. In addition, this paper estimates the amounts of energy subsidies ...

  • On the formulation of environmental fugacity models and their numerical solutions

    Multimedia models based on chemical fugacity, solved numerically, play an important role in investigating and quantifying the environmental fate of chemicals such as persistent organic pollutants (POPs). These models have been utilised extensively in the study of the local and global distribution of chemicals in the environment. This paper describes potential sources of error that may arise ...

  • Regulatory models for environmental impact assessments in Hungary

    This paper describes the methodology and input requirements of environmental impact assessments regulated in Hungary by national standards for more than 10 years. The main characteristics are (a) various models simulate the impact of point, multi-source, line and area sources on local, urban and regional scales, (b) design transmission matrices are readily available for the greater part of the ...

  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

  • Using atmospheric dispersion modelling as a tool in environmental impact statements: the Israeli experience

    This paper describes the authors' experience in using the US EPA Gaussian models in making environmental impact statements which focus on four different fields highways, quarries, an airport and tunnels. The main problems encountered are the uncertainties in the emission factors, the lack of accounting of the complex terrain effects and the fact that the Israeli Standards relate to total ...

  • Environmental indicators in economic models: technical information and policy implications

    Environmental policies in industrialised countries are directed at phenomena like the greenhouse effect, acidification, eutrophication and waste accumulation. Environmental indicators, being a weighted average of individual emissions, measure each phenomenon. Since policymakers tend to have a preference for quantitative policy goals, improving the environment unarguably implies a reduction of ...

  • Environmental effects of transport: a model of optimal pricing and investment for the UK

    This paper models the effects of imposing efficient pricing on interurban passenger travel in the United Kingdom and passenger travel in London. Both the internal and external costs of the main modes are estimated. The resulting efficient prices are used to predict the changes in demand for each mode, together with implied tax revenues, operators' aggregate surplus or deficit, and the implied ...

  • Use of scientific inputs for environmental policymaking: the RAINS model and the Sulfur Protocols

    This article discusses the use of Integrated Assessment Models for supporting the decision-making process in environmental issues. In particular, we discuss the case of sulphur emissions and the RAINS model, used in the process of negotiation of the Oslo Protocol (signed in June 1994), in relation to new targets for sulphur emissions reductions. To illustrate how scientific tools are not simply ...

  • Environmental macroeconomics: from the IS?LM?EE model to a social welfare approach

    In answer to Daly's original call for an environmental macroeconomics, Heyes incorporated an environmental constraint in the form of an EE or "ecological equilibrium" curve into a simple "Investment/Savings (IS)-Liquidity/Money (LM)" model (Heyes, 2000). Some criticisms and extensions to the Heyes proposal were presented by Lawn to reflect open economy issues and the implications of technological ...
