Bogus "Green" or "Mean" Ratings for Cars
- =v= A group called the American Council for an Energy-Efficient
Economy does yearly ratings of cars, producing lists of the
"greenest" and "meanest" (environmentally speaking):
There was all sorts of news coverage about this, almost none
of it mentioning that, um, the numbers being used are bogus.
Only the _Boston_Globe_ pointed it out:
| But future rankings from the American Council for an
| Energy-Efficient Economy may look significantly different
| from this year's list. The group uses Environmental
| Protection Agency estimates for its mileage figures,
| and the EPA is changing its testing procedures to better
| reflect real-world driving.
(I posted details about this change to this list back
Hybrid ratings are especially exaggerated.)
=v= Add to this some research from last April which takes
a full-lifecycle approach (including the impact of the cars'
manufacture), which I also posted to this list:
That particular study was done by a market research firm,
so it's sorely in need of corroboration. If the American
Council for an Energy-Efficient Economy is going to make
publicity with "green" and "mean" lists, they should take
these factors into account as well.
