Methodological note on the CBA of Open Science practices

This report describes the CBA framework (hereafter the OS CBA framework) specifically developed for the assessment of Open Science practices. It draws from the research carried out by PathOS, whose objective is to identify and quantify the Key Impact Pathways of Open Science relating to the research system and its interrelations with economic and societal actors. This framework is expected to become a benchmark tool for assessing the Open Science thus ensuring consistency in measuring the impacts of Open Science by considering not only benefits but also costs and, moreover, comparing them with a scenario when OS is not available.
