What would economics aimed at a sustainable planet look like? I guess this is quite an interesting question, are there any elegant solutions to penalising climate change in the same way a land-value tax penalises passively holding on to land? We definitely need to wean ourselves off unbridled consumption at any rate, even if it wasn't an ecological nightmare it's terrible for people's mental health. Existing to consume like chickens in a human battery farm is no way for a sentient species to live. Any country attempting to combat climate change using economic means would absolutely have to use "green tariffs" I think, otherwise businesses would simply export their emissions to the developing world on an even greater scale than they do today.
