Which Is Greener?
Which uses less energy and emits less pollution: a train, a bus, or a car? Advocates of rail transportation rely on the public’s willingness to take for granted the assumption that trains — whether light rail, subways, or high-speed intercity rail — are the most energy-efficient and cleanest forms of transportation. But there is plenty of evidence that this is far from true.
Rail advocates often reason like this: the average car has 1.1 people in it. Compare the BTUs or carbon emissions per passenger mile with those from a full train, and the train wins hands down.
The problem with such hypothetical examples is that the numbers are always wrong. As a recent study from the University of California (Davis) notes, the load factors are critical.
The President’s New Cars
I had an op-ed yesterday in USA Today about President Obama’s proposed new fuel-economy standards. Don’t like ‘em. Unfortunately, an editing snafu over at the newspaper inadvertently left out the fact that there are four models at present that meet the proposed new standard — the 2010 Honda Insight (41 mpg) and the 2010 Ford Fusion Hybrid (39 mpg) were left off the list.
Space prohibited me from making an additional point. Even if there is no rebound effect, my colleague Pat Michaels finds that global temperatures will only be reduced by 0.005 degrees Celsius by 2050 and 0.0078 degrees Celsius by 2100 once you plug those emissions reductions into the computer models used by the IPCC. Of course, proponents contend that U.S. action on fuel efficiency will lead to like action abroad. Well, good luck with that. But even if all of the signatories to the Kyoto Protocol adopted Obama’s proposed fuel-economy standards, global temperatures would be reduced by only 0.038 degrees Celsius by 2050 and 0.071 degrees Celsius by 2100. If you tried to monetarize those benefits, you would be hard pressed to come up with an defensible number of consequence.
So what should be done instead? Nothing. At the risk of sounding politically irrelevant, there is no good case for the government to reduce U.S. gasoline consumption via fuel economy standards or fuel taxes; an argument I made at length in a study I co-authored almost two years ago with my colleague Peter Van Doren.

Obama’s Fuel-Economy Standards
If you like driving a big car or SUV, the good news about Obama’s new fuel-economy standards is that they won’t dictate what kind of car you will be able to buy in the future. If you want to buy a 15-mpg SUV, Detroit (or Aichi or Wolfsburg) will be free to make and sell you one.
The bad news is that the standards may make your car more expensive. Corporate Average Fuel Economy (CAFE) standards are actually calculated as the mean of gallons per mile, not miles per gallon. So, as of 2016, for every 15-mpg model made by an auto maker, that company will have to make five models of cars that can go 50 mpg in order for its fleet to meet Obama’s new target. Since bringing each new model to market can cost billions of dollars, if there are not enough people who want to buy those fuel-efficient cars to cover their design costs, the company will have to add a share of those costs to your SUV.
Simultaneously Destroying and Subsidizing the Auto Industry
The Obama Administration has announced new fuel-economy regulations and emissions rules that will boost the cost of new car by at least $1300. This is probably another nail in the coffin of the American automobile industry, but Jerry Taylor is the guy to provide thoughtful analysis. When I read about the new White House scheme, the first thing that came to my mind was this extremely clever video (yes, I am envious that my videos are not this creative) about the type of car we will all be driving if politicians continue to run amok:
