The total amount of pollutant (that is) emitted annually by vehicles at OIA is twice as much as(指代the amount of pollutant) is emitted anually by all motor vehicles in the CMA.
这里的as ... as中as是连词不是代词,lz如果要把as作为代词来用,那么就不存在as ... as句型。如果要用,必须是as... as + 与比较对象平行的结构。
2
the economy
might not be as weak as (the economy that) some analysts previously thought to be(might be).
比较的两部分总要平行的,前半句是might be后面的部分最好是might be
Environmentalists provide initial evidence that airports are a larger source of pollution than they were once believed to be
另外这两句话后面比较部分的主语不一样,不能套用相同结构。

as much annually as is emitted by the
four times
as many
Americans were killed
as
观察一下,后一句as之间有名词,这应该是他做代词的前提。
than sb expected/though当常规用法记吧,应该是冗余
the economy might not be as weak as (the economy that)
some analysts previously thought to be(might be).
Environmentalists provide initial evidence that airports are a larger source of pollution than
they were once believed to be
我的意思是第一句主语是分析者,第二句主语是被分析者
