The Sustainability Accounting Standards Board (SASB) has published an XBRL Taxonomy that is worth having a look at. This is the press release announcing the XBRL Taxonomy. Also, they are taking public comments. You can download the SASB XBRL Taxonomy and fiddle with it, learn from it, test your software, etc.
If you want a quick way to look at the SASB XBRL Taxonomy (and you have a bit of patience as this page loads); this web page shows an overview of the XBRL presentation relations of the entire XBRL taxonomy. (There are about 19,000 lines on the HTML page.)
