 It's been a wonderful opportunity to bring together representatives from the private sector, the investment community, research groups, non-profit organizations, some intergovernmental organizations to talk about how private sector and investors might provide greater leadership in helping communities, countries achieve higher levels of sustainable resource use and livelihoods environmentally sustainable uses of resources through their corporate activities. So this very much involves taking up global standards of good investment with respect to environmental use of land and natural resources. It very much involves how companies take account of the social and economic interests of poor people or small over farmers or indigenous communities who live and work on land that companies want to invest in. How do we better take account of their interests and bring them into these investment activities in ways that they benefit also. So what we're really looking at potentially is a whole kind of shift in the paradigm of how we view the role of the private sector in helping society achieve its environmental sustainability goals. I do, I think this is actually an expression of that momentum this meeting because in the last three to five years we've seen a shift in company thinking to wanting to be part of the solution to these problems. There's an understanding that company survival access to, it very much depends on access to resources that are sustainably used or protected and managed. We're seeing considerable alarm among corporate leaders about the impacts of climate change already on climate, on changes in weather patterns, negative impacts on crop productivity and production, more frequent extreme weather events, storms, tornadoes, flooding and these are all, in many ways the corporate leadership have sort of gotten the message much more directly. It's affecting their bottom line in ways that some of our political leadership have not got the message, if you will. So this is really an expression of this momentum I think and we're moving away from the notion of kind of impact investing as it's called, being kind of a boutique kind of undertaking it kind of makes the investor feel good, they're willing to tolerate maybe a lower way to return in favor of sort of making a contribution to the community, shifting in sort of much more mainstream. If you're not producing commodities through clean value chains, you're generating all kinds of risk as a company. You're exposing the investor in that company to reputational risk. Consumers are expecting commodities to be produced sustainably so if you're not meeting those expectations, you're not going to be selling your commodities in highly valued markets. This is becoming a core part of the business kind of calculus, sustainability really pays and if you're not producing sustainably, capital is going to cost you more money, you face the risk of not having access to important markets. Well some number of companies are already behaving differently and these are sort of companies with marquee brands, Unilever, Nestle, Coca-Cola, they represent a large proportion of the source of demand for commodities. The markets that they serve, they have consumers who are setting higher demands but they're still not, they're forgiving it but they're not the whole community of corporate activity and some of the research reported around the conference indicates that once you look at the top 20 global companies and you see very rapid implementation of sustainability standards, once you drop below that top 20, the commitment to standards really drops off very quickly. So there's a lot of work to be done in the corporate sector. Consumers need to set even higher expectations of another range of companies. So getting control of your supply chain or understanding what happens in it is very hard work and companies are investing, some number are investing very heavily and assuring that their suppliers are producing commodities in a sustainable way and are socially responsible. But it's very, very difficult for learning, companies are known for some time to sort of assure clean, you know, sustainably produced products in the value chain. So there's a lot of work to be done but there's a lot of leadership coming out of the private sector in the pursuit of that.
