When organisations apply the same ethical, social and environmental accounting (ESEA) method they can form a network of responsible organisations. The account data of all organisations within the network can be aggregated to discover trends, correlations and other insights within the network. Cleaning and aggregating data can be a tedious task without inadequate tool support.

We propose openAggre, a model-driven tool that clean ESE account data and aggregate and visualise the data based on aggregation specifications.
