People don't want to think about climate change every time they do every decision. They can't. What a carbon tax does is it nudges them in the direction of doing the right thing. But you can cut other taxes in response.

The push is the R&D, the pull is the carbon tax. Yes, the government will be somewhat inept, but the private sector is in general inept. How many companies do venture capitalists invest in that go poorly? By far most of them.

You then offset that [carbon tax] with a reduction in payroll taxes, dollar for dollar. And that's why I was so flexible. It's a tax swap, that's what I was talking about. It wouldn't grow the government, and it would approximate the attachment of these negative externalities to combustion fossil fuels.

The cost of a carbon tax (likely less than 0.8% of GDP) is well south of the expected costs of warming by 2100 (as mentioned earlier, a conservative 3.6% or more of GDP).

By taxing carbon dioxide (the harmless trace gas which makes the planet greener), the US government would be signalling to the world that it still believes in the man-made global warming narrative. This, in turn, would keep alive the crony-capitalist “renewables” industry in which Paulson, Steyer, Bloomberg and their friends are so heavily invested.

Carbon taxes are undermined by free trade. If you put a tax on carbon-emitting activity in the U.S., it'll raise the domestic price of (for example) coal.

Therefore, carbon credits, carbon taxes, and related schemes are actually more about fueling environmental finance than environmental responsibility. The credits are less about projects and research in sustainable production systems and more about the financial interests underlying the market for carbon credits.
