What are 3 positive outcomes of shutting down the keystone pipeline?

The obvious benefit of this project is that the company, TC Energy, stated it would have created around an estimated 10,400 American jobs and 2,800 Canadian Jobs.

However, there are always tradeoffs to these situations, some being more consequential than others.

i would say your answer is a)
