 The unique thing about WaterSmart is firstly that we're taking a digital approach to a sector that has been dominated by physical science. WaterSmart helps utilities and their customers to behave in ways that are more effective and more efficient. To save money, to save water and to save energy. And what we're doing is we're bringing together various strands of science that aren't common in utilities at all. Computer science, computer science, data science and also design to make this as accessible as possible and as effective as possible in changing the behaviour of a very broad segment of the population. Our mission is to change the way that the world uses water and one of the things that gives us great advantage is that we're a B Corp, a benefit corporation. We have a dual mandate, not just to create shareholder value but also to advance our mission and to do so in ways that are good for our employees and for the communities that we work with. One of the key things that we do here is we focus on experimentation. You're not going to get every bet right but that means you've got to make a lot of bets and be very much aware of when they're getting off target and so it's fine to fail but you've got to fail fast. Utilities, frankly, are not where the cutting edge generally is and so we look at the world around us, we look at experiences from mobile communications, from entertainment, from financial services and so on and we bring all of those to bear. It's that combination that's really the magic. In terms of the impact so far, we've been able to help utilities really deliver on the mission of clean, safe water for everybody and reasonable prices. Already we've been able to save more than 15 billion litres of water and more than 20,000 tonnes of CO2. What people forget is that in every drop of water there's quite a lot of energy and a lot of associated greenhouse gases and we're simply not going to make our COP 21 commitments if we don't address that element of the problem. Access to clean, safe water is essential to modern society and we're advancing that cause.
