Abstract: A computer implemented method for generating sustainable performance and environmental impact assessment for a target system, comprising: receiving input data associated with the target system; receiving sustainable performance and environmental assessment rules of the target system; generating assessment dataset containing a plurality of data items based on the received input data; determining applicable impact assessment data for each of the data items in the assessment dataset using dynamic adaptive recognition data comprising pre-configured recognition data; applying the applicable impact assessment data for each of the data items in the assessment dataset to generate an impact dataset; and determining sustainable performance and environmental impact assessment information of the target system using the sustainable performance and environmental assessment rules and the impact dataset.
