To better categorize companies that share similar resource intensity, as well as sustainability risks and opportunities, SASB has created the SICS. 

At the highest level SICS has 11 vertical sectors and at its most granular level there are 77 industries. 

Truvalue Labs has integrated SICS into Truvalue SASB Codified Edition, therefore all 30,000+ companies covered in the tool have been mapped to a SICS Sector and Industry.
