Sound policy would involve increasing significantly the currently near-zero price of emissions of carbon dioxide and other greenhouse gases.

The science is very clear. However, carbon tax by itself won't be enough. It should combined with meaningful direct support for clean techs.

The price should be raised much closer to the point at which the negative externality of C02-induced climate change is internalized.

Carbon pricing is not the only sound policy. Regulation may play a roll as can cap and trade.

I agree if we mean the world price. This is not rational if ONLY only US (or California) does this. World problems require world policies.

Won't be enough, need more energy sources that are not fossil fuel reliant too.

Bringing the private and social costs of emissions into line via taxes has short and long term efficiency benefits.

The price is zero in most of the country, and fossil fuels are still subsidized. Politicians would rather subsidize & regulate than tax.

A price of ~$40 will make deep reductions in the power sector; elsewhere, it is helpful; but technology & other policies are needed too.
