Also, the pp who said it was an original idea, it's not, this is the duplicate of the Goldman Environment Prize, which William could have promoted, but I guess he wanted his own name on something
It’s not really a duplicate. The key difference with the Earthshot Prize is the idea that this is not just rewarding an idea, but funding the scaling up of the winning ideas to maximise their impact. It’s more like an environmental “The Apprentice” in that regard than just a cash prize (the cash involved is 5 times more than the Goldman prize also). A Prize Global Alliance, including global companies such as Arup, Bloomberg., Deloitte, Herbert Smith Freehills, Hitachi, Microsoft, Salesforce, Unilever, Vodacom, and Walmart,has been announced, with Michael Bloomberg, UN Environmental Head - to help the winners "scale up" their winning ideas. That kind of access will be invaluable (and previously unobtainable) to the nominees.
So it’s not just recognition, but aims to ensure implementation and development as well, which is different to other prize schemes.
