gase不能用可数名词few的，
你有可能会说那a也用了few of了啊，但是few/less of加单复数名词都可以。

还有就是they的指代不清，and和also语义重复。

comma+ as well as +现在分词/名词形式 ，修饰前句，主语随前句主语

In C and E, fewer carbon dioxide is incorrect. Fewer is used to refer to something countable; carbon dioxide is not countable. (Please note that fewer other gases also is incorrect; the correct wording is fewer OF the other gases.) Eliminate C and E.

In D, less...other gases is incorrect. To discuss the NUMBER of the other gases, the correct wording is FEWER of the other gases. To discuss the AMOUNT of the other gases, the correct wording is LESS OF the other gases. Eliminate D.

In B, having been implicated is used -- incorrectly -- to modify gases. Having + past participle is used to indicate an action that:

-- is completed before the primary action attributed to the modified noun
-- provides context for the primary action attributed to the modified noun

For example:

Having enjoyed the book, John cannot wait to see the movie.

In the sentence above:
Having enjoyed refers to John.
Cannot wait is the primary action attributed to the modified noun John.
Having enjoyed was completed in the past; John cannot wait in the present.
Having enjoyed the book explains why John cannot wait.

In B, the other gases (the modified noun) are not performing a primary action. Hence the use of having + past participle is inappropriate. Eliminate B.

The correct answer is A.

In A:

As well as + VERBing = preposition + gerund = adverbial modifier.

To elaborate:
-- as well as is a preposition.
-- emitting is a gerund -- a verb functioning as a noun. Emitting is the object of the preposition as well as.
-- The entire phrase -- as well as emitting far less carbon dioxide gas -- is an adverb modifying the previous clause.

The following are analagous constructions:

In addition to emitting less gas...
Besides emitting less gas...
As well as emitting less gas...
