> I don't think your math is right on that- higher efficiency in ICE vehicles would mean that the Tesla vehicles displaces fewer ICE vehicles, would it not?
Hard to tell - the report doesn't show all it's math so there are two ways to interpret. But I'll post the relevant paragraph from the report here:
> Over 550K Tesla vehicles have been sold, and they have driven over 10B miles to date, resulting in a combined savings of over 4M metric tons of CO2. This is the equivalent of saving emissions from being released into the environment from over 500K ICE vehicles with a fuel economy of 22 miles per gallon (MPG).
The way I read that, the hard number is 4 million metric tonnes of CO2 (which they determined is equivalent to 500000 vehicles at 22MPG, given average distances driven and CO2 output from that amount of gasoline). If my interpretation is correct, it would be equivalent to (500000*25/22=) 568 thousand cars at 25 MPG (the more efficient cars put out less co2 per mile, so the same amount of co2 reduction is equivalent to more cars).
But it may just be worded poorly, and they know how many cars it kept off the road, and calculated their emissions savings based on an equivalent average of 22 MPG. In which case, your calculation would be correct.
