  • 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 ...

  • 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 ...

  • 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 ...

  • Modelling farmers’ participation in agri-environmental schemes in Greece

    Agri-Environmental Schemes (AES) are the main policy instrument currently available in the European Union to encourage environmental improvements in agriculture, but their adoption in Greece and generally in Southern Europe is relatively low. Policy makers have still limited experience on how farmers approach environmental schemes. The aim of this paper is to examine the factors that determine ...

  • 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 ...

  • 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 ...

  • Environmental knowledge creation and management process: formalisation, diffusion and valorisation model

    To integrate the environment in product design is neither a recent processing method nor an original one. However, one can easily note that in spite of all declarations made in this domain, it remains difficult to know and to evaluate the environmental qualities of a product, and therefore to know a fortiori if this product is "better" or not than another one. Without separating the ...

  • 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 ...

  • Canarina CUSTIC software · environmental noise modeling · algorithms 4

    In the railway case, we shall calculate the noise level in a similar way. For airports, we shall use the next equation Leq=Leq(300m)-20Log(r/300) where Leq(300m) is the noise level at 300m from the airport. This model performs satisfactorily for simple sound ...

  • 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 ...
