Both the LCA and EEIOA model rely on manipulations with matrices, filled with data on technologies, emissions, and environmental impacts. Developments in LCA databases, e.g. at JRC-IES, and in EEIOA databases, e.g. at Eurostat, lead to the creation of ever-increasing datasets. The handling of such datasets in terms of retrieval, storage and processing urges for a need to rethink the computational paradigm. This paper sketches some of the developments.Text/Conference Paper
