Carbon Tax

The carbon tax is the carbon-pricing lever Kyle flags as a core takeaway from How To Avoid a Climate Disaster. In his own words, the idea is to “force energy producers to recognize the environmental costs of the energy their customers consume” — the carbon-price argument in its most direct form. The book’s reasoning, which Kyle’s note tracks: zero-carbon solutions look more expensive only because fossil-fuel prices don’t reflect the environmental damage they inflict; correct the pricing and the substitution to clean energy happens organically. The book offers Denmark as a historical example — pairing renewable-energy R&D with a feed-in tariff and, later, a carbon tax after the 1970s oil shocks.

Context: A carbon tax is a fee levied on the carbon content of fuels, designed to internalize the social cost of greenhouse-gas emissions (a Pigouvian tax on a negative externality). It is one of the two main carbon-pricing mechanisms, the other being cap-and-trade.
