Do climate policies have a budget 'black hole'?

Without 'purchasing' cost-effective climate policy in a fiscally responsible way, it's harder to 'sell'.

Without money for the 'purchase', will politicians opt for ineffective climate policies (eg, a very low carbon price) to maximize revenue collections? Will we see an 'emissions watch' climate policy?

That would be an efficiency-sapping 'con job' – very bad for a productivity-challenged Australia.

There's more. Climate policies plan to increase emissions costs substantially over time. Emissions 'caps' will be reduced, real carbon prices increased, and purchases of emissions cuts rise, pursuing more ambitious emissions reduction targets.

Must we 'purchase' these increased costs, too? Where's the money coming from?
