Sometimes it's hard to explain negative numbers in real world contexts, but credits are real impact to total coal/gas demand.

If the credits are used to fund someone else buying renewable energy in lieu of fossil fuels, then the impact is that fewer fossil fuels are consumed.

So if I pay someone $10 to buy solar energy instead of coal they were otherwise going to buy, while I buy that same amount of coal, then the net effect is zero additional demand for coal. You can say that it's just an accounting exercise, but the real world effect is actually real.
