一个句子的语法分析

今天在看ISO14001英文版的时候看到一句话，这个句子语法结构自己没弄明白，希望有兴趣的朋友来帮忙分析分析。
It applies to those environmental aspects that the organization identifies as those which it can control and those which it can influence。
这里的as是什么词性？as those which it can control and those which it can influence 是修饰environmental aspects 的呢还是和those environmental aspects 并列的？
