I see that the New York Times ran a piece over the weekend pointing out lefty hypocrisy on a handful of green issues. Residents of liberal enclaves like Brooklyn, Berkeley, and Cape Cod proclaim to worry about the environment, but when bike lanes, or bus-rapid transit, or wind farms are planned for their own backyards, they suddenly become remarkably indifferent to the carbon impact of their preferences. What’s always striking about these pieces is how easily the two ideas co-exist in the mind of the NIMBY; the bike lane is obviously a huge problem — dangerous for drivers even — and, oh yes, we should totally take steps to limit auto-dependence.

The Times piece delves into the psychology of this kind of neighborhood opposition, but what it doesn’t say is that as annoying as this is, it has a far smaller impact on net emissions than the far more common anti-development strain of NIMBYism. Bike lanes make New York City a teeny bit greener. But New York is already much, much greener than most American cities, thanks to its dense development pattern and extensive transit network. Net emissions fall a lot more when someone from Houston moves to New York than when someone from New York starts biking.

Happily, lots of people would LOVE to move to New York. This is one huge benefit we don’t need to subsidize to realize. Unhappily, the benefit is nonetheless out of reach because of the huge obstacles to new, dense construction in New York. New York can’t accommodate more people unless it builds more homes, and it can’t build more homes, for the most part, without building taller buildings. And New Yorkers fight new, tall buildings tooth and nail. They fight them on aesthetic grounds, and because they’re worried about parking and traffic, and because they’re worried about their view, and because they just think there’s enough building in New York already, thank you. And many do this while heaping massive scorn on oil executives and the Republican Party over their backward and destructive views on global warming.

Of course, the obstruction of development is offensive for lots of reasons: it makes housing and access to employment unaffordable, it reduces urban job and revenue growth, it tramples on private property rights, and so on. But the environmental hypocrisy is galling, and it’s not limited to New York. My old neighborhood, Brookland, voted overwhelmingly for Obama (about 90-10, as I recall). Many of the locals are vocally supportive of broad, lefty environmental goals. And yet, when a local businessman wants to redevelop his transit-adjacent land into a denser, mixed-use structure, the negative response is overwhelming, and residents fall over themselves to abuse local rules in order to prevent the redevelopment from happening.

This project would bring new retail with it, which would enable more local residents to walk to a retail destination. It would bring new residents, and those residents would be vastly more likely to walk or take transit to destinations than those living farther from Metro. Forget the economic benefits to the city, the people occupying the new housing units would have carbon footprints dramatically below the national average. But this basically does not matter to the NIMBYs however much they profess to care about the environment.

To the extent that public opinion matters and can be shaped, I think it would be a huge boon for humanity for attitudes toward NIMBYism to turn decidedly negative. People should be ashamed of this behavior, which is both selfish and extravagantly dismissive of property rights.
