A climate academic says the COP climate conferences have achieved little in actually cutting emissions.

It comes as COP29 takes place in Azerbaijan, with a new deal forged which will see developing countries supported to the tune of $500 billion to manage climate impacts.

But Victoria University's Adrian Macey told Mike Hosking more must be done, and thinks the conferences have become unproductive.

“We go into each COP saying: ‘this is the last chance to save the planet and if we fail here, there’ll be dire consequences’, and we go ahead and fail.”

He says we need more transformational change.

"Yep, it's useful to have that, but in terms of the planet, it isn't a game changer in actual reduction of emissions."
