The goal of this almost completed project has been the development of a user-friendly, workflow-based assistant software that guides facility operators through the rather complex and time-consuming course of the EU Emission Trading Scheme (ETS). ETS is one of the European Union's key instruments towards reducing greenhouse gas emissions. During the project, the ITspecific requirements of the German ETS have been analyzed with respect to stationary facilities and and later as well to aviation. Based on this analysis, prototype assistants have been implemented using the .NET-based plug-in framework Empinia, which has also been extended by a re-usable, workflow-based assistant engine. This paper reviews the present results with a focus on the practical lessons learned from the analysis and development.Text/Conference Paper
