I don't quite understand why they use "due to" in this sentence. Can somenone explain it to me?
Unesco's World Heritage Committee is due to consider adding the reef to its list of sites that are "in danger".
Lexico/Oxford's explanation of due to doesn't help:
Caused by or ascribable to.
Because of; owing to.
If I substitute any of those four phrases for due to in the quote about Unesco, it still makes no sense.
