Phasing out fossils fuels would go a long way to stopping dangerous climate change – but it might be harder than we thought.
Melbourne is one of the fastest-growing cities in the developed world, and the other big Australian cities aren’t far behind.
With the failures of past planning now apparent, the unruly threat of a damaged and depleting planet is ushering us toward a fourth era of urban restructuring. What might City v4.0 look like?
South Africa has made promises to decarbonise but is hugely reliable on coal - so this is difficult.
