I suggest you check your calculations. The well-to-wheel CO2 emissions of an
ICE averages 1.25x the tailpipe emissions. According to the EPA, the well-to-wheels
CO2 emissions of a 2015 BMW M5 (auto) are 554 g/mile at the tailpipe + 126 g/mile upstream = 680 g/mile or 423 g/km. Upstream includes everything associated with gasoline -- drilling, refining, and transportation. Your chart shows 2592 kg/500 km = 5184 g/km, which is about 12 times higher than the EPA number.
thats what i dont get, my numbers are extremely conservative on the gas side, i dont think the epa is actually including every number associated, there is a reason why a drilling rig costs $1M to punch a hole in the ground.
get this, it takes around 100 semi truck loads to move a rig (how much diesel is that?)
you are moving that rig in the middle of nowhere, which means you have to make your own road (how much diesel is that?)
before you even make the road you use helicopter for mapping the area (how much av-gas is that?)
then when you think you have a place mapped out you need to clear lines of trees for kms for ground radar (how much diesel is that?)
then you have more semi trucks roll in for ground radar equipment and thumpers (how much diesel is that?)
after the rig makes the hole, you need to build your holding tanks and valves and whatnot to have the oil flow, the equipment is so large the company im at had to use several Antonov- 124's to make the trip to the nearest airport and truck the rest of the way (the fuel for this is ridiculous)
the camps for the workers requires at least a 2MW generator running non stop (this alone will double the number as it does not stop running the entire time even after the well is dry, the diesel requirements is crazy)
the lights, the work trucks (usually hundreds of these), and any other equipment all have their own fuel requirements and are generally running non stop, and they all require maintenance
generally workers work on rotation, month on month off type of deal, they are flying to site every rotation and the back to back guy is flying home, how much aviation gas or jet fuel is that? we are talking hundreds of people worth of plane trips every month
i didnt include any of those steps,
You need to include the lithium mining, transport, and refinement since that's always the argument against EVs.
no manufacturing was included because i would have to include the same stuff for the internal combustion vehicle, im just including what "differs",
look at how many parts there are for an equivalent power output engine (JUST THE ENGINE! no transmission or anything else)
for the Tesla this is similar, it would differ by only several parts
