I want to say the most important measures lack priority:
car free cities, permaculture, passive heating/cooling building design
car-free itself saves time, lives, money, energy and is economically vibrant. car centric design is financially insolvent. It is climate mitigation and adaptation. It costs far less than renewables and especially EVs. It the pathway for a sustainable future developing nations can embrace.
It should be a top priority but isn’t.
