At the end of the day though, Australia could be the world leader in climate change action and reduce our emissions drastically, and the world may not follow suit. China may continue to produce more and more emissions etc.
Cleaning up the environment is good, I am all for that. However, the reality is that most company's are asses driven purely by profit. If they see an opportunity to move overseas and use cheaper labor/cheaper production methods (that may be less environmentally sound) to get more profit, then they will do that. In fact we have already seen many do it. It is a fine balancing act.
