"How a coin for carbon could save the planet"
Interesting idea! Such coin price could even be linked, in some way, with the CO2 European Emission Allowances price.

This is precisely what ETS (Emissions Trading System) already is - you can buy the permissions, and you can trade them. They already *are* a commodity, so a new coin is not necessary. The problem is what you can actually buy for the coin, because this is where it gets political - for example, Germany "avoids" massive amounts of CO2 emissions by burning wood which of course emits CO2 but in ETS it's declared as zero-emissions.
But proof of stake (PoS) requires well, a stake, so a massive upfront investment you need to keep frozen, which again prioritises the largest and wealthiest players. For example, the proposed stake for mining Ethereum is 32 ETH which is around 64'000 GBP today. For PoW you also need investment in the form of mining devices and cheap electricity, but that can be scaled, at least in theory.
