From ManhattanGmat:

i think the combination of "amount" and "as much as" would be tagged as redundant and therefore wrong.

i am not 100% on this, as the gmat's usage preferences are rather slippery at times, but there's no doubt that this suggestion is inferior to the version without "as much as".

shorter versions:
amount X is twice as much as amount Y --> inferior, and possibly even wrong (redundant)
amount X is twice amount Y --> undoubtedly better

Here is my take on this question:

Providing initial evidence that airport are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago metropolitan area.
A. as much as that which is being emitted annually by all
That and which together are not right.

B. as much annually as is emitted by the
Altered intent because the word “all” is dropped.

C. as much compared to what is annually emitted by all
Unidiomatic: Idiom is “as much as”

D. that emitted annually by all
Correct. This is an eclipse. Notice the fully blown sentence:

Providing initial evidence that airport are a larger source of pollution than they were
once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice [the total amount of pollutant]emitted annually by all motor vehicles in the Chicago
metropolitan area.

Replace with our eclipse:
Providing initial evidence that airport are a larger source of pollution than they were
once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice that emitted annually by all motor vehicles in the Chicago
metropolitan area.

E. that emitted annually compared to the
Unidiomatic: “compared to” is used for examining similarities. “compared with” could be used”.
