True, but that's a separate category for two reasons:

1) Because the emissions profiles of said vehicles are dramatically different, and it's unfair to drivers of low-emissions passenger cars to conflate them. "Everyone who drives" can't be said to be equally culpable if the minority that drive SUVs and trucks produce more than 2/3 of personal-transportation emissions.

2) Because the usage profiles are different. Yes, many light trucks are driven as personal vehicles, but they're also used for real work that even non-drivers are reaping the benefits from. When the cable guy or the plumber comes to your apartment building to make a repair, they come in a light truck.

I wish the numbers broke down emissions by usage type instead of or in addition to vehicle type, but we don't have that. As is, I'm comfortable saying that somewhere between 5.8% and 16.5% of our emissions come from personal transportation, and I don't believe that that alters my argument in any meaningful way.

By that logic you could further include semi trucks that deliver groceries by extension. Pick your side.

I'm thoroughly confused. I'm saying that many uses of light trucks (such as plumbers and cable guys) should not be categorized as personal transportation. Why does me excluding such uses lead to a logical extension that includes semi trucks?
