SPS doubts

Thor, I posted this link a few months ago for Paul, but I think you may find
it interesting as well:

In conclusion, the position of dumping SUVs is hypocritical at best, since
no-one is doing it in any quantity sufficient to make an impact. At any
rate, even if they did, the overall impact on the situation at large would
be insignificant. Therefore, it would seem to be much better for the cause
focusing debate and other energies on solutions that have more than a
snowball's chance in the hot nether regions of being implemented at all, and
that when implemented would have an effect more appropriate to the general
problem. Wouldn't you agree?
