As a follow up to Steve's very interesting post about Amyris, I thought 
I'd post this brief  piece about the potential virtues of a carbon tax 
that was published in last week's Economist magazine.

/The Economist/ has long advocated a carbon tax as the best way to deal 
with climate change. Carbon taxes are a subspecies of Pigovian 
<> tax; taxes that are 
designed primarily to change behaviour rather than to raise revenue. The 
idea is to try to manipulate the price of a good or a service in order 
to capture all the negative externalities it imposes.
