I added this comment to Kristof's blog following his "conservation is good" NYT OpEd:
Conservation = Carbon Tax.
It's a fairly simple equation. I'm disappointed that you chose not to mention it. I understand it's probably wise to let people slowly draw their own conclusions, but it is a bit dishonest.
You know perfectly well that the only way to accelerate conservation is by an overt carbon tax or by a hidden tax (regulatory mandates).
To that end, I'd like to see a "carbon tax PAC" that we could all contribute to. It makes far more sense to send $25 to a "carbon tax PAC" than to spend $25 on a low energy light bulb.
Perhaps you're constitutionally opposed to taxation. That's where we can negotiate. I'm ok with shifting funds, so the revenue raised through a carbon tax is offset by cuts on capital gains, increasing personal exemptions, increasing EITCs, etc.
