Net Benefits of CAFE stadards

I just frittered away an hour poking holes in a 2002 paper from the American Enterprise Institute and the Brooking Institution that purports to show a net cost to society from higher CAFE standards. Even using the paper’s questionable results, my calculation show an a posteriori net benefit had CAFE standards been raised at the time the paper was written.

Here are links to the original article on Knowledge Problem that spurred me to defend CAFE standards, a link to the AEI/Brookings paper, and my comments on the weaknesses in the paper’s analysis.

    It is inherently impossible to make a accurate estimate for mileage on hybrids where they can be plugged in to recharge, you could only do so after a large number of them had been in use for a long time, anything else is just a set of assumptions which may or may not be vaild. You could make an estimate based on no use of the battery and tehm a second figure based on some assumed average of battery driving which results from charging at home, but what about where charging at home is via a lead acid battery set up wich draws paower from PV panels? estimating Co2 emissions is really going to be quite fraught with difficulty.
