  • Static and dynamic instantaneous emission modelling

    Emission models can be categorised into three categories: average speed models; traffic situation models, used at macro-scale or meso-scale level (national, regional, city level); and instantaneous (modal) models, useful at micro-scale level (street, vehicle level). To improve the existing instantaneous emission models, some preconditions must be fulfilled: the emission signals should be measured ...

  • Modelling fuel consumption and pollutant emissions based on real-world driving patterns: the HBEFA approach

    Emissions of passenger cars and light-duty vehicles with complex exhaust gas after-treatment are difficult to predict, especially if the prediction is only based on kinematic parameters without vehicle-specific data. A new method for modelling fleet emission factors based on testbench data is presented. It has been used for modern passenger cars and light-duty vehicles (EURO-2 and -3) in the new ...

  • Real options and CO 2 reduction policies for climate change

    Managing CO 2 emission control policy is a complex problem because of uncertainties in CO 2 emission process and CO 2 uptake, and irreversibility in investment decisions. Traditional method using benefit cost analysis for evaluation of CO 2 reduction policy is not effective in presence of deep uncertainties. Real options analysis approach is an alternative methodology which incorporates ...

  • The role of temperature in tropospheric ozone

    After evaluating some meteorological simulations, we detect an error of over 5°C in surface temperature. In order to assess the effect of this anomaly in temperature, we perform new simulations of an emission model and a photochemical model using the correct surface temperature in the meteorological data. Our goal is not to solve the problem in surface temperature estimates, but to reveal how it ...

  • LCP/IRP strategy development using an optimising energy-emission model

    This paper proposes an energy-emission modelling approach for the development of least-cost planning and integrated resource planning strategies for electric utilities, and presents results of the model application to the municipal electric utilities of Karlsruhe and Rottweil. The LCP/IRP strategy employed is based on the regulatory practice in Germany, also with regard to liberalisation issues. ...

  • Kinetics of the atrazine degradation process using H2O2-UVC

    This work is concerned with the intrinsic reaction kinetic of the degradation of atrazine (ATZ) using H2O2-UVC. Experimental runs were carried out in annular photoreactor. The initial concentration of ATZ was 2.2 × 10−2 mol m−3 while the H2O2-ATZ molar ratio range was 0–578 mol H2O2 mol−1 ATZ. The ATZ molecules are decomposed by means of free-radical attack ...

  • Impact of energy efficiency upgrade retrofits on the residential energy consumption and Greenhouse Gas emissions in Canada

    The impact of various energy efficiency upgrade scenarios on the annual energy consumption and Greenhouse Gas emissions of the Canadian housing stock is assessed using the Canadian Residential Energy End-use Model (CREEM). The energy efficiency upgrade scenarios that are considered include major retrofits, such as the improvement of the house envelope by adding insulation, and the replacement of ...

  • Is there a cointegrating relationship between Australia's fossil-fuel based carbon dioxide emissions per capita and her GDP per capita?

    Carbon dioxide (CO2) emission per capita of Australia, a high-income economy with a fossil fuel-rich fuel-mix, is proven to have a strong cointegrating relationship with her gross domestic product (GDP) per capita. A conditional equilibrium correction model (ECM) has been developed to quantify the relationship between the two variables by employing the autoregressive distributed lag bound-testing ...

  • Emission behaviour of modern heavy duty vehicles in real world driving

    Within a national and two international research projects, a vehicle emission model was developed, which calculates emissions in real world driving from the engine emission maps by simulating engine power and engine speed. Influences of transient load changes on the emission level are taken into consideration by special functions. Model parameters are gained from a common measurement protocol on ...

  • Characterising emissions from private passenger vehicles using engine operating patterns

    A method to simulate emissions factors using frequency distribution plots of engine speed and engine load is proposed. The distribution plots and corresponding emissions factors were developed from speed time series' of real-world driving cycles and physical properties of a range of private passenger vehicles tested at the EMPA. Emissions factors were estimated for a set of simultaneously ...

  • A monitoring system to control effects and effectiveness of traffic measures in urban areas

    Within a project on environmental traffic management in Braunschweig, Germany, (“UVM Umweltorientiertes Verkehrsmanagement Braunschweig”) a monitoring system has been installed as part of an environmental traffic management system (ETMS). This paper describes the layout, the application and the validation of the monitoring system. The effectiveness of implemented ...

  • Application to Northern Italy of a new modelling system for air quality planning: a comparison between different chemical mechanisms

    A modelling system has been developed for the analysis of photochemical pollution. It is composed of three modules: CALMET meteorological model, POEM-PM emission model and TCAM model. The system can accommodate chemical schemes based on both lumped molecule and lumped structure approaches. Application to an intense ozone production episode occurred in northern Italy has been performed. The ...

  • Emission predictions with a multi-linear reservoir model

    ABSTRACTFor the assessment of combined sewer overflows detailed models are not necessary. Physically based conceptual models give an optimal balance between model uncertainty and uncertainty in the input data. Besides, it is important that continuous long term simulations are performed. To prove this, in this paper the calibration of a reservoir model is discussed. The emission results of the ...

  • An assessment of urban VOC emissions and concentrations by comparing model results and measurements

    From September 1994 to June 1996, the city of Antwerp carried out a volatile organic compound (VOC) measurement campaign in the urban agglomeration of Antwerp. The results were used to further validate a traffic emission model for the city of Antwerp and to evaluate the performance of three different "street canyon" models that were applied to calculate benzene concentrations at ten ...

  • Northern shipping: Is the anticipated climate boost a bust?

    Visions of safe passage for cargo ships across the Arctic between Europe and Asia have sprung up in recent years as ice-free zones have appeared along the northern coasts of Russia and Canada. Some shipping companies already have begun taking advantage of the change. But dreamers and schemers may want to think twice about the long-term promise of the so-called Northern Sea Route for boosting ...
