What is the difference between an implementer and a promoter of the AWS Standard?

An implementer is a specific site, facility, farm or geographically-bounded operation that is putting the AWS Standard into practice. A promoter is not directly implementing the standard, but rather encouraging others to implement and “using” the standard to advance their interests. For example, a farm that was using water may choose to be an implementer to address their shared water challenges, while the retailer that sources from that farm (or investors in the retail company), may be promoters to address their supply chain water risks.
