The intrinsic value of any art is what someone is willing to pay for it.
For example the world’s most expensive NFT, The Merge by Pak, sold for $91.8 million. Its price was higher than the sale of Jeff Koon’s Rabbit, the most expensive artwork by a living artist at auction. It’s all about personal tastes and how deep folks wanna dig in their pockets with this stuff.
IMO it seems RECs are a better solution than carbon taxes at least in situations like this. With RECs you’re buying renewable energy to offset non-renewables, with a carbon tax the company is just giving the government money for use of non-renewables. Only funds spent on RECs in this case actually go to supporting the renewable energy sector. I’m no expert in this stuff so I could be off, just how I understand it.
