Sure.
You come back to the question of revenue neutrality, or how I prefer to think about it is, are we increasing or changing the overall size of government?
There's really one policy on the table that will allow you to both implement strong incentives for green innovation and keep the size of government the same or smaller, which is to implement a carbon price that you, then, refund through credits or lower taxes. That's certainly a policy option that's on the table.
The alternative is large government-funded subsidies, regulatory initiatives, etc., which increase the size and the role of government in solving this problem.
