What are the two levels in the sustainability portfolio that deal with "beyond greening" activities that tend to pay off in the longer term?

What will be an ideal response?

Today's greening activities focus on improving what companies already do to protect the environment. The beyond greening activities look to the future. First, internally, companies can plan for new clean technology. Many organizations that have made good sustainability headway are still limited by existing technologies. To create fully sustainable strategies, they will need to develop innovative new technologies. Companies can also develop a sustainability vision, which serves as a guide to the future. It shows how the company's products and services, processes, and policies must evolve and what new technologies must be developed to get there. This vision of sustainability provides a framework for pollution control, product stewardship, and new environmental technology for the company and others to follow.
