growth movement’s promotion of "more<br />

scientific planning" for how land will<br />

be used, buttressed, of course, by "strict<br />

regulations.” 195 This makes it impossible<br />

to build the lower cost starter homes that<br />

are affordable because of cheap land on<br />

the urban fringe.<br />

In the past, some environmentalists<br />

even celebrated the potential<br />

demographic impact of densification,<br />

seeing in denser cities a natural<br />

contraceptive. Stewart Brand, who<br />

in 1968 founded the Whole Earth<br />

Catalog, embraces denser urbanization,<br />

particularly in developing countries, as<br />

a force for “stopping the population<br />

explosion cold.” 196<br />

More recently, climate change has<br />

been used to justify greater density.<br />

“What is causing global warming is the<br />

lifestyle of the American middle class,"<br />

insists New Urbanist architect Andres<br />

Duany, who is himself a major developer<br />

of dense housing. 197 One retro-urbanist<br />

author, David Owen, in his book Green<br />

Metropolis suggests that the planet needs<br />

to live in densities associated with his<br />

former Manhattan home, although he<br />

himself moved to bucolic Connecticut. 198<br />

Sadly, much of the research<br />

advocating density as a solution to<br />

climate change is deeply flawed, since<br />

it usually excludes greenhouse (GHG)<br />

emissions from common areas, including<br />

elevators, and from lighting fixtures,<br />

space heaters and air conditioners,<br />

usually because data is not available.<br />

Research by Energy Australia, which<br />

took this and overall consumer energy<br />

spending into account, found that town<br />

houses and detached housing produced<br />

less GHG emissions per capita than<br />

high density housing when commonarea<br />

GHG emissions were included. 199<br />

In addition, one recent study from the<br />

National Academy of Sciences found<br />

that New York City, despite its transit<br />

system and high density, was the most<br />

environmentally wasteful of the world’s<br />

27 megacities, well ahead of more<br />

dispersed, car-dominated Los Angeles. 200<br />

In one of the most comprehensive<br />

nationwide reviews of greenhouse gas<br />

emissions, Australian Conservation<br />

Foundation research showed per capita<br />

emissions to decline with distance from<br />

the urban core, through suburban rings<br />

Advocates of strict land use policies<br />

claim that traditional architecture<br />

and increased densities will enable<br />

us to once again enjoy the kind of<br />

“meaningful community” that<br />

supposedly cannot be achieved in<br />

conventional suburbs.<br />

outward. 201 Another study, this one in<br />

Halifax, Nova Scotia, found the carbon<br />

footprints of core residents and suburbanites<br />

to be approximately the same. 202<br />

Higher densities, according to data<br />

in a recent National Academy of Sciences<br />

report, can do relatively little—perhaps<br />

as little as two percent—to reduce<br />

the nation greenhouse gas emissions:<br />

"Urban planners hoping to help mitigate<br />

CO2 emissions by increasing housing<br />

density would do better to focus on<br />

fuel-efficiency improvements to vehicles,<br />

investments in renewable energy, and<br />

cap and trade legislation." 203 Economist<br />
