Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
But are there any statistics for the carbon cost of trashing and replacing still-working vehicles (whose manufacture-related emissions could be considered a "sunk cost") with new ones, relative to the carbon saved by the more efficient engines?

I'm not much in favour of bailing people out of foreseeably stupid and irresponsible decisions like buying an SUV for private use, unless the benefits to the whole of society are both clear and substantial.

Are they?

I was just going to ask how many years of use would there need to be for society to gain a net energy advantage out of getting the individual a new car out of their usual buying cycle?

Any idiot can face a crisis - it's day to day living that wears you out.

I'm sure there are stats on how much energy it takes to make a new vehicle, but there are several forces at work.

One is to reduce demand relatively quickly to bring down the price (assuming that's what is keeping oil high). It is hard to quantify how much making oil cheaper in Africa is "worth" under these circumstances.

Another is to give a boost to auto production which is (still) a big factor in the US economy when there is a downturn. This would also provide an incentive to automakers to switch to more efficient production sooner than the new standards mandate. This is also hard to quantify.

California had a program to buy back old junkers that were on the road a few years ago to help lower pollution. I think this was regarded as a "good thing" without a rigorous cost/benefit analysis.
