The auto industry is an interesting case. No, I haven't specifically modelled that sector, but it is in the model, and it comes under other manufacturing or light manufacturing.
On the emissions from that sector, from production, there's no issue, really. It is really about selling cars and the transportation side, and what you do there. It seems to me that sector is very insensitive to the emission price, and that explains why emission standards and ethanol fuel standards are really being driven forward.
