This is quite the claim. If true I'd imagine Big Oil and conventional car manufacturers would be trumpeting this far and wide. Because it is such a sensitive issue (climate change and all that) we must double-check to be doubly sure of the sources of any of these graphs and data. I know this annoys people but we really need a source for these claims[0], so citation please! http://www.divergentmicrofactories.com/wp-content/uploads/2015/06/DM_emissions_flat.png http://www.divergentmicrofactories.com/wp-content/uploads/20...

This makes no sense. How can one 25MPG gas car require over twice the "fuel manufacture" of another 25MPG gas car? Also, how does a hybrid vehicle cost less to manufacture than an comparable gas-only car?

  A part made from cast aluminum will have a significantly higher environmental cost than the same part made from cast steel because pulling aluminum out of the ground is much more expensive environmentally, and monetarily (fuel/electricity aren't free) than getting the equivalent amount of iron out of the ground. Even if you make the parts from melted down anvils and beer cans that initial cost is still there (there's also a lot less aluminum around to be recycled than there is iron and steel). Materials and methods of processing matter a great deal. OEs care very much about this but the progressive fuel economy requirements make it worth their while meet the requirements all else be damned

That visualization seems all kinds of messed up. Why did they split up the "operations emissions" and the other two into separate "bars" (or obnoxious cute images of cars and smoke stacks...) How far are they assuming the vehicles travel over their lives? It's hard to tell what the actual numbers are.
