My take - The Carbon Tax Is Dead, Long Live the Carbon Tax?
While I'm inventing traditions, how about a new one that a blog post riffing off another blog post should directly steal the headline?
So I'm riffing off of William's post regarding the lab experiment in Washington State, with a revenue-neutral carbon tax in 2016 failing (William appears to obliquely refer to this one), and now a revenue-generating carbon tax in 2018 also failing.
For the audience of climate bloggers and their readers, I'll put the most relevant-to-them point first rather than bury it like I usually do: scientists and engineers seem to treat scientific and engineering challenges as legitimate while political challenges are somehow illegitimate combinations of incompetence and corruption. As a once (and apparently, now again) small-pond politician, I'll just say the political challenges of climate change would be easy if you could provide perfect long term and short term localized forecasts, and provide a no-cost engineering solution to the problem. These are all human problems.
Political challenges are as mind-bendingly difficult. Neither William nor Tyler Cowen are announcing magic solutions that will win political contests, so maybe that's a recognition on their part that the challenge is real.
Not that I have a magic solution either. I think Churchill's sayings about democracy being the worst government type except for all the other types, and that Americans can be counted on to do the right thing after exhausting all other options, might apply to Washingtonians. Maybe third time's the charm for Washington State, and some impure compromise between the two prior initiatives can succeed.
And speaking of impurity, there's the fossil fuel companies. Yes, the public has moral agency and protecting democracy is ultimately up to them, but fossil fuel companies throwing sand in their eyes and buying out their representatives isn't helping. They more than deserve their share of blame, especially as they hypocritically claim to support a carbon tax and then do their best to stop one from happening.
I'll end with a only half-joking suggestion: "Tax Carbon, Not Trucks, Beer, or Harleys". Set up a carbon tax, and stop taxing cars, trucks, beer, and motorcycles. The government gets to keep the extra tax revenue after making up for the lost tax revenue from those other sources.
