David Ekchajzer – Paris-Saclay University, Univ-Evry, IMT-BS, LITEM, 91025, Evry-Courcouronnes – is a doctoral student at LITEM. For the past three years, he has been involved in developing open methods, data, and tools for assessing the environmental impact of digital technology. In an industrial context, he supports projects run by the company Hubblo and the association Boavizta in an open research and development approach, combining open data and open source to promote more transparent quantification. These contexts enable him to use management sciences to analyze the reciprocal influences between methods for analyzing the direct and indirect environmental impacts of digital technology and the organizational, interorganizational, and strategic dynamics of companies producing digital technology.
