Techno-economic databases in the context of integrated assessment modelling

Techno-economic data on emission reduction technologies and their validation are an important basis for the derivation of costefficient international reduction strategies for air pollutants through Integrated Assessment Models like RAINS. However, there is often a lack of transparency with regard to data quality and origin. This paper discusses a methodological approach which can be applied to derive and classify the techno-economic information needed on emission abatement options. It further illustrates how such data have been implemented in the techno-economic database ECODAT, that has been developed as support of the RAINS databases, and as a publicly available tool allowing to trace and also evaluate data on emission control technologies in various industry sectors. These data can then be used for further modelling.
