    How about:
    The vehicles explain the cause of air pollution in the cities.

    Phrasal Verb:
    account for
    1. To constitute the governing or primary factor in: Bad weather accounted for the long delay.
    2. To provide an explanation or justification for: The suspect couldn't account for his time that night.
    That's from dictionary.com. I think #1 is an accurate model for your sentence.

    How about this sentence?
    "lightning accounts for 10 percent to 15 percent of the electricity bill."
    Thanks.

    Same idea - "causes," "leads to."

    Without lightning, the electrcity bill would be 10-15% smaller.

    My understanding of it:
    payment for lighting is a part* of the whole electricity bill

    part = 10 to 15 %

    In the following context, does "account for" mean "figure out"?

    ***********************
    The company has repeatedly proved its ability to push emerging technology into the mainstream—but with FaceID, Apple claims to have conquered many of the challenges that have prevented the widespread use of facial biometrics. But a number of computer-vision researchers say they are skeptical that a smartphone-based system like FaceID can account for things like variable lighting conditions or subtle changes in a person’s appearance to create a secure-yet-practical way to unlock a phone a dozen or more times a day.
