1) We don't know if it is fossil fuel. It is used to power vehicles, but there hasn't been indication that this is done through internal combustion.

2) "the end that its usage will affect the environment, like global warming." Global warming is caused because of the use of our fossil fuel, not the termination of it's use. WoR didn't state that the consumption of dust would lead to any negative effects on remnant.
