"In this case if they won the government to be legally required to reduce emissions rather than just having a 'target'."
And if this ended up being the case as a Gov you would need to start to reining in/ completely stopping anything that has to do with fossil fuel production or use in regards to the economy etc.
Therefore the budget would have to take a serious hit.
The first place I would start trimming up budget spending would indigenous spending/ handouts/ Sitdown money etc $30 plus billion per year.
Cut that by at least 50 % straight up and then slowly reduce to nothing over the next 10 years years.
You make the bed in which you lay, you can't have it all your own way.
