I totally get some of your points, but I am sorry to say that most aren't quite true.
> Easier data sharing among organizations
It is more complex than pulling that data from a random DB or API.
> Decreased inefficiency for currency exchange rate and cross border transaction costs
Since most people need to buy crypto currencies with fiat they need to pay for that conversion, then they need to pay for the transaction, then you need to pay again to send that crypto to the tree planting folks and then again they need to turn in into fiat.
It would be far easier and less expensive for you to handle everything in USD or EUR.
> Easier reporting and analysis
Same as the other point, you can do everything pretty simply with any DB and some lines of code.
> Platform of choice for next generation of climate change advocates and supporters
This is hardly a point
> Smart contracts enabling decentralized calculation of carbon offset for many daily activities
Computational power of smart contracts is incredibly limited and HIGHLY energy intensive. There is actually no good reason to perform those computations on a decentralized network. It would also be very expensive, much more than any other alternative.
> Crypto mining is a great source of emissions, its way easier to plug our DAO into the existing networks to calculate and offset transaction emissions in a user friendly way
That actually sounds as a counter point.
So... man, it is really less impactful on the environment and also less expensive and less complex to open a non profit in a country with a stable fiat, open source your model and make all data public (except donors personal data, just give them a UUID).
Plus, charity is usually tax deductible almost anywhere, why would anyone want to donate anonymously? You can also accept cryptos as donations, that's not a problem, but you are more likely to lose contributions by not accepting fiat than the other way around.
That's why I said I can hardly see the point of being a DAO in your case.
