At C40, we don't claim a monopoly on innovative solutions. So when we hear of developments going on outside of the network, we will on occasion share them with our audience. Which brings us to a new campaign being developed to remedy the problem of basic access to clean water. And it features an interesting leader – the hospitality and tourism industry. The social enterprise, called WHOLE WORLD Water, announced a campaign last week that will encourage spas, hotels and resorts to bottle and sell their own water, then make donations from the proceeds towards clean water programs.
