The only thing to account for the Insights lower score is that it's made entirely of aluminum, which is more energy intensive to refine than steel. However recent articles have stated it is less energy intensive to use aluminum than steel over a fullsize vehicles lifetime because of the mpg gained in weight savings.
The CVT gets a better score because it has less NO2 emissions making it cleaner. The MT has less Co2 emissions though.
As it stands the Insight is more eco friendly than many electric cars on that list. If you used the actual mpg you get, it would be equal or darn near close to superior. Which is already saying a lot for a the poor "mild" hybrid drivetrain.
