The Koch Brothers’ Americans for Prosperity has a project http://www.noclimatetax.com to oppose carbon and other taxes that would address climate change.

Oddly, the website is filled with spelling errors and awkward prose:

We don’t believe it is appropriate to hide tax hike in environmental bills. … This approach allows us to have open an honest debate about whether we should act on climate, as well as having open and honest, and quite separate, debate over the appropriate level of taxes. (source)
