According to the calculations of the National Highway Traffic Safety Administration (NHTSA) this proposal will:
1) Have no net benefit to society in terms of costs and benefits.I would add that the projected benefits of the NHTSA analysis are so small as to fall well within the range of modelling error. And that's not to mention the fact that no one has yet developed a climate change model that can produced reliable results anyway.
2) Result in the loss of almost 50,000 auto manufacturing jobs in the U.S. over the next 5 years.
3) Have a "trivial effect" on global climate change: by the end of this century the proposal would a) reduce atmospheric CO2 concentration by 0.2%, b) reduce global mean surface temperatures by 0.007º C., and c) reduce sea-level rise by 0.6 mm.
I would also note that if automakers are successful in producing such fuel-efficient cars, then U.S. oil consumption will likely decline, and that could well lead to lower oil prices, cheaper gasoline, greater oil consumption in countries that do not impose such standards, and more miles driven in the U.S. At the very least, reduced gasoline consumption in the U.S. would free up oil to be burned in other countries with less efficient cars and trucks. As a result, the future impact on global climate could actually be zero or even the opposite of what is intended.
Why are we letting some egomaniac force such dramatic change on our economy, our lifestyles, and our freedoms, if there is no demonstrated benefit to anyone? Where is the outrage???
