I think it's quite a complex relationship, actually.
When we talk about leadership, it's often the case that leadership can be found from the private sector just as much, if not more so than in government.
I think, in many respects, it's how governments take on this responsibility and ensure that not only is it not marginalized but it's covered across all different departments, with leadership from a key central agency at its core. There is much to learn of how the private sector, how businesses actually incorporate a sustainability approach, if you like, to ensure their performance is actually meeting and ensuring environmental targets that governments have introduced.
In many respects, there are examples around the world where corporations are actually imposing and showing leadership, and showing the way on how governments need to be taking on business, how they need to be introducing targets, and how they need to be ensuring that they have the right strategy to meet those targets.
When we talk about sustainability, it is up to all of us, isn't it? It's up to governments. It's up to business, and it's also up to the public at large. We all have a relationship to play. I think the relationship among those three different sectors is actually very key.
There are many elements, the bottom up, the grassroots level, which are really demonstrating action in this area, because they're tired of waiting for governments or private sector to take the lead. There are many examples around the world where we can actually learn from one another, and I think that relationship is quite sophisticated. There needs to be elements where we can learn from one another. We talked about lessons learned. I think this really needs to be brought out a little more.
