Today's Trucking: Yup, carbon the next truck 'pollutant' targeted
Caterpillar has already announced it's leaving the US on highway engine market thanks in large part to the 2010 rules. Daimler has announced an end to the Sterling line (and the firing of 4500 workers) in March of 2009 thanks in part to the upcoming rules and the aftermath of the 2006 prebuy (though given Daimler's history it seems possible that this move was in part in retaliation for the 2006 strike in the Sterling plant in St Thomas, ON).
Now in the midst of this, the EPA has another wonderful plan to reduce choice and increase cost. We were emitting less carbon (i.e. burning less fuel) before the EPA killed fuel economy with the last rule changes (and the trucks cost $20K less). now the EPA will work hard to make sure we can pay even more and maybe get the economy we had before.
