Welcome to EcoSense

EcoSenseWeb2 is an integrated atmospheric dispersion and exposure assessment model which calculates external costs related to the exposure to airpborne pollutants with a focus on impacts on human health. The main goal of EcoSenseWeb2 is to support the assessment of different air pollution mitigation strategies by providing informaiton about their effectivness and cost efficiency.


Currently, we do not provide any publicly available version of EcoSenseWeb2. If you wish to use EcoSenseWeb2 for your research project, please contact us to discuss possible collaborations.
If you used the previous version of EcoSenseWeb and you want to retrieve some of your results please let us know. We will then provide you with an possibility to retrieve your resultsets.

For rough estimations of external costs and more aggregated impact calculations we provide a simplified version, EcoSense LE, which is free of charge.

Background and Methodology

Impact Pathway Approach

EcoSense implements and follows the Impact Pathway Approach developed in ExternE to calculate external costs. The main focus is to assess net benefits of different emission reduction scenarios across Europe.

In a first step, changes in concentrations are translated into changes in air pollution concentration levels by taking into account the dispersion and chemical transformation of different pollutants. To allow for a fast computation time, EcoSense uses so-called source-receptor matrices instead of a full atmospheric dispersion model. Source-receptor matrices link the change in emissions in one country to a change in concentration in a specific area. The EcoSense source-receptro matrices are based on the EMEP/MSC-W dispersion model

Next, the actual exposure is assessed and physical impacts are derived by applying concentration-response-functions which relate several health outcomes to changes in air pollutant concnetration levels. EcoSense implements most concentration-response functions as recommended by HRAPIE (WHO). Currently, EcoSense assesses impacts due to long-term exposure to Particulate Matter (PM), Nitrogen Dioxide (NO2) and Ozone (SOMO35).

Finally, the physical impacts are translated to a common metric called "Disability adjusted lifeyears" (DALY) to be able to consider mortality and morbidity impacts simultaneously and reflecting their severity at least to some degree. Impacts are also stated in monetary values with a willingess to pay approach for a year of life lost applied on mortality impacts.
