Ruining our cities to save them

On the other hand, attempts to concentrate jobs will throw thousands onto the dole queues. At least this is a type of solution: the unemployed don’t commute.

Ironically, some thriving “centres” in the Herald plan wouldn’t exist without the expansion of Sydney’s arterial road network. Examining the “edge city” phenomenon in Sydney, Peter Murphy and Robert Freestone conceded, way back in 1994, that the jobs-rich “global arc corridor” owed a lot to strategic road junctions like the intersection of Lane Cove Road with Epping Road in North Ryde and with the Pacific Highway in Gordon.

“The most prestigious development has overwhelmingly favoured the middle-ring northern and north-western parts of Sydney in centres easily accessible by car ...” say Murphy and Freestone, having explained that “there are now diversified employment centres in the suburbs which have grown up almost despite, rather than because of, traditional land-use planning policies”. These days the NSW Government bows to green intimidation, failing in its new Metropolitan Transport Plan to complete the highly successful Orbital Motorway Network, leaving M4 West, the F3 link and duplication of the M5 tunnel in limbo.

Demands that at we reshape our cities to fight climate change are illogical. Let’s assume, for argument’s sake, that there’s a case to cut Australia’s 1.4 per cent contribution to global carbon. Even the Australian Conservation Foundation’s Consumption Atlas ranks urban settlement patterns well below the general level of consumption as a factor in emissions. And general consumption is a function of living standards, not urban form. Since the world is far from putting constraints on consumption, calls for a transformation of settlement patterns are baseless.

But it’s worse. The Consumption Atlas and an analysis by Demographia’s Wendell Cox disclose that emissions across affluent inner-urban areas exceed those on the fringe. By focusing on settlement patterns rather than consumption levels, green planners engage in a form of class discrimination. The costs of climate change are heaped on outer-suburban working people, who lose jobs, mobility and housing amenity, while the affluent emerge unscathed.
