Their Global Social Compliance Committee meets to monitor key issues and trends as well as review strategies and best practices. However, there is no mention of specific practices.

confirm (pg. 2): "Our Global Social Compliance Committee brings together subject matter experts and senior leadership from across the globe and across different functions to collaborate, monitor key issues and trends, review strategies and best practices, and help guide the strategy and execution of the program. In addition to our Global Social Compliance Committee, our Chief Risk and Compliance Officer, who is a member of our Global Social Compliance Committee, provides an annual update to our Board of Directors on our Global Social Compliance Program and meets regularly with our Board and the Audit and Finance Committee of the Board."

I would say this outlines how they monitor change through internal governance reporting.
