No, I think it means: "Say whatever is necessary to make our customers and stockholders feel warm & squishy about us."
It's like how every corporation/state or local govt/university/labor union, etc, touts their diversity, and how much they value diversity, and that diversity is their priority, etc.
"Sustainable," like "diversity," is a a feel-good word. Nobody means anything by it. They just feel good saying it, and hearing themselves say it, and hearing others say it.
