Hehe, Lois
"How many gas guzzling SUVs do they have in Iceland?"
Terribly many, and only USA (AFAIK) exceeds us in terms of cars per inhabitant.
This is recent, and simply due to good economy, - people do indeed stop "gizzling" when it hits the purse. However, the average wallet up here is now thick.
However, the road system is rather long pr. inhabitant, and I belive the miles pr. inhabitant are not so high.
(Well, you always have to take a lot into the account)
Sidenote here, (personal) - I prefer to keep honest about these things. This might not suit my "agenda", - or rather thesis regarding concern of emissions. But right is right, and I prefer the Churchillian way of a no-bluff when it comes to these "politics". I also belive that with straight (and possibly friendly) approaches like this, more "educational" feedback is achieved rather than through bashing and humiliating as well as hurting victories or losses in debates.
Maybe just me, but I stick through this theory,,,,and it's not easy

As for the impact, the country is easily self-sustainable - energyvise. We basically export energy AFAIK.
Oh, and as a sidenote, I don't even have a car

(...sort of....but I mostly go by foot, and therefore I don't need a guzzler to drive me to the gym )
