Welcome to the group.
BONSAI is a platform which aims to provide open data on sustainability assessment. You can read more about BONSAI here .
Its an open community with members across different domains contributing towards it.
Currently we are in the process of integrating one of the commonly used datasets to the semantic web. The name of the database we have currently integrated is called Exiobase. It is a global multi regional input output database used for the analysis of the environmental impacts associated with the final consumption of multiple product categories (including textile).
This data can be queried if you have some experience with SPARQL. One of our members Romain Sacchi has developed a web application which should enable us to query the data easily i.e knowledge of SPARQL not required. However, when he developed the web application our dataset was not ready. Based on your introduction I think you might be interested supporting us with.
