The author very specifically points that out:
> ...our cars primarily exist to connect things, things that require immense extraction and fossil fuel energy to build, run and maintain: roads buildings factories shopping centres suburbs cities airports and so on. It is not just the car itself that is unsustainable; it is our entire way of life and the system that underpins it.
I can almost understand this for roads (but buses still need those, too!). Literally everything else is entirely orthogonal to cars or the lack thereof; abolishing cars entirely v. switching to electric-only would have zero impact there.
This is absurd. If people move away from the suburbs, the trees will still be there, and more if we get into reforestation. Building a suburb generally involves cutting down trees. Humans living in a smaller area of the planet leaves more room for trees.
Only for cities/suburbs that exist in forested areas. This would exclude most desert and prairie ecosystems (for example).
> Humans living in a smaller area of the planet leaves more room for trees.
Sure, mathematically-speaking, and planet-wide. On a more local scale, though, this is not necessarily the case.
There's also the consideration for relative density of CO₂ sources v. sinks. I don't have any actual data here, so feel free to ignore this, but my hypothesis is that urban areas would have significantly higher CO₂ densities than suburban areas (which would in turn have significantly higher densities than rural areas, and in turn wilderness areas), and this high-density CO₂ would not readily/easily/immediately disperse / would be more difficult for surrounding carbon-sink areas (like wilderness and - I'd argue - potentially suburban areas) to even receive, let alone absorb. You thus end up with big lingering blobs of CO₂, continuously fueled by human occupation, and unable to disperse. Spreading out humans would better spread that CO₂ sequestration load, thus allowing better efficiencies.
I've become convinced that density really is the answer to building a more humane way of living.

This was in an area where (IIRC) the mandated minimum lot size was 1 acre, and the vast majority of properties were 5+ (I lived on 8).
And the author fails to explain why (in the context of climate change) that's actually a problem. Suburban areas have a disproportionate carbon footprint specifically because of ICE-powered cars being required to go anywhere; if those ICE cars become electric cars, and that electricity comes from solar/wind/nuclear/hydro/geothermal/etc., then... where, exactly, is the carbon footprint?
Hell, at that point the suburban areas could actually be net carbon sinks, given there's more room for big carbon-devouring trees in between single-family/duplex/quadruplex homes than there typically is between skyscrapers packed as tightly as possible (as is the norm in even small cities, let alone large ones).
