Models and Tools

The software system developed within the ExternE project:



EcoSenseWeb - the integrated environmental impact assessment model. The so-called 'single source' version of EcoSense can be obtained for a handling fee of 310€ after signing a licence agreement (please contact It allows to calculate location specific marginal external costs of a stationary source (e.g. a power plant) due to emissions of air pollutants. The user can modify all relevant input parameters. Other versions of EcoSense (e.g. 'multi-source' to calculate external costs for all sources of a sector and/or country or for the whole EU) are under development.


EcoSenseLE is an online tool for estimating costs due to emissions of a typical source (e.g. power plant, industry, transport) or all sources of a sector in an EU country or group of EU countries. It is a parameterised version of EcoSense, based on European data for receptor (population, crops, building materials) distribution, background emissions (amount and spatial distribution), and meteorology. The input required is annual emissions of NOx, SO2, PM10, NMVOC, CO2, N2O, CH4; the pollutants considered are O3, SO2, PM10, sulfates, nitrates and greenhouse gases. The cost calculation is based on ExternE exposure-response function and monetary values, user defined valuation of mortality and greenhouse gas emissions is possible.


Currency Conversion Tool

The Currency Coversion Tool is an MS-Excel application developed in course of the EU-funded MethdodEx project (2007): “Currency converter, including currency, year and PPP conversion developed by Harry Walton at the university of Bath”. The tool provides assistance for currency conversion in two respects:

  1. Conversion of currency of one country into the currency of another country via exchange rates and
  2. Conversion of the value of one currency in one year into the value of the currency in another year via consumer price indeces.

Therefore, the tool has been updated to include currencies of 20 countries worldwide and to cover the years from 1982 to 2010 by Wolf Müller at the University of Stuttgart. The tool has been developed to consistently conduct value transfers, e.g. US$(2005) into Euro(2010), via exchange and depreciation rates. For transfers of values of willingness-to-pay, PPP-adjusted exchange rates are available. For transfers of other values, market base exchange rates should be applied. For inflation adjustments within the EU, the EU harmonized consumer price index (HICP) while for international adjustments a deflator based on the OECD CPI is suggested. In addition, an adjustment based on nominal GDP per capita is also possible for benefit transfers.
