If we achieve our sustainability targets and no one else follows, we will have failed.

Leadership is not just about giving energy ... it's unleashing other people's energy.

If you work at an insurance company that sells premiums you wouldn't even sell to your mother, how happy would you feel to work there? It's going to eat you up. It might last a few years, but it doesn't attract the best people, and it certainly doesn't create the energy and engagement you need to be a long-term performing company.
