Climate Change: Another emergency

Yesterday the Greater Wellington Regional Council unanimously declared a climate emergency. They've also set themselves a goal of being carbon neutral by 2030, though this only applies to their direct emissions. Still, its a good step, and as usual it invites the question: where is Parliament? When are we going to see some national leadership on this issue? Or was the Prime Minister's talk of climate change as "my generation's nuclear-free moment" simply hot air?
