 So my name is Pierre Rousseau. I'm an independent consultant for finance and sustainability. I'm a senior associate at CISL. As you know CISL is developing a lot of concepts around sustainability and it's good sometimes to interact with people like us who are in the reality of each businesses, on the reality of some new businesses and so to make the connection between what has been developed outside and what has been developed inside CISL. I do believe that today sustainability is a very generic word and what is important today is to be able to bring some action around sustainability and for that I do believe that I developed this idea about the 4E education important for educating people especially the different type of and the different group of the society. I think we need also to engage, engagement. We need to bring more people to be engaged in order to create a critical mass. We need also some empowerment because empowerment is very important in order to make sure that we go to the right direction and everybody is following. And finally I do believe efficiency. I do believe if we do a lot of things efficiency on the way we work but also efficiency on the way that we have to develop the world of tomorrow I do believe that we will bring a lot more of sustainability. We need to drive ideas, we need to test ideas so it's very important also that they take the best practice and the best standard but it's also not only just to develop them and to show them but also to try to influence the entire society, the different parties of the society in order to convince and to bring as many people as possible. I will give you maybe one practical example. There is an activity happening now in South Africa a project called Terra Green which is about to renovate and to rehabilitate the lands mining lands and all lands and the purpose of that is to create a group integrating the community, the scientists, the financing people, the corporates in order to put everybody around the table in order to rehabilitate those lands. So I do believe that projects like that should be the future project that needs to be replicated at a different place of the planet in order to work in a collective way because the collective in the change will make the real change for the sustainability of this type of project.
