Turning carbon in the environment into CO2 by oxidizing it is NOT carbon neutral! If that was the case, then every car, plane, and coal power plant would be “carbon neutral”. That’s very obviously not the case.
Being “carbon neutral” means that you, or the operations of your business or your national economy, emit the same amount of carbon dioxide into the atmosphere that you offset by some other means. (Source)
It’s ALL about CO2! For the love of god, go read some articles. You have no idea what you’re talking about.
