A journalist of some renown called me last week to ask a question: would it be possible to do both a cap-and-trade program and a carbon tax? Al Gore famously urged that approach, but this journo had heard from other (reliable) sources that it’s not possible.
My instinctive answer was yeah, sure, there’s no reason you couldn’t do it. (I mean, there are a gazillion political reasons it’s impossible, but there’s no technical or regulatory reason you couldn’t do it.)
Is that right? Do any of you smart folk out there know of any reason you couldn’t implement the two policies in parallel?
