That's a good question.
I'm not sure how the term “ensure” would be interpreted. As members are aware, there's an obligation in the act on the Minister of Environment and Climate Change to consult with other ministers in order to ensure a whole-of-government approach.
Whether this would give the environment minister some extraordinary powers, I am not able to opine on, but I think the underlying objective here is clear that the minister needs to take as broad a suite of actions as possible.
