Not In My (Liberal) Backyard

Last week, two groups of New Yorkers who live "on or near" Prospect Park West, a prestigious address in Park Slope, filed a suit against the administration of Mayor Michael R. Bloomberg to remove a nine-month-old bike lane that has commandeered a lane previously used by cars.

In Massachusetts, the formidable opponents of Cape Wind, a proposed offshore wind farm in Nantucket Sound, include members of the Kennedy family, whose compound looks out over the body of water. In Berkeley last year, the objections of store owners and residents forced the city to shelve plans for a full bus rapid transit system (B.R.T.), a form of green mass transit in which lanes that formerly served cars are blocked off and usurped by high-capacity buses that resemble above-ground subways.

Critics in New York contend the new Prospect Park bike lane is badly designed, endangering pedestrians and snarling traffic. Cape Wind opponents argue the turbines will defile a pristine body of water. And in Berkeley, store owners worried that reduced traffic flow and parking could hurt their business.

But some supporters of high-profile green projects like these say the problem is just plain old Nimbyism — the opposition by residents to a local development of the sort that they otherwise tend to support.

"It's really pretty innocuous — it's a bike lane, for goodness' sake — their resistance has been incredibly frustrating," said Walter Hook, executive director of the Institute for Transportation and Development Policy in Manhattan and an expert on sustainable transport. He lives in Brooklyn and uses the Prospect Park West bike lane to get around.

Nimbyism is nothing new. It's even logical sometimes, perhaps not always deserving of opprobrium. After all, it is one thing to be a passionate proponent of recycling, and another to welcome a particular recycling plant — with the attendant garbage-truck traffic — on your street. General environmental principles may be at odds with convenience or even local environmental consequences.

But policymakers in the United States have been repeatedly frustrated by constituents who profess to worry about the climate and count themselves as environmentalists, but prove unwilling to adjust their lifestyles or change their behavior in any significant way.

In Europe, bike lanes crisscross cities, wind turbines appear in counties with high-priced country homes and plants that make green energy from waste are situated in even the wealthiest neighborhoods. So what is going on here?

Robert B. Cialdini, an emeritus professor at Arizona State University who studies environmental behaviors, points to two phenomena:

Humans hew to the "normative" behaviors of their community. In places where bike lanes or wind turbines or B.R.T. systems are seen as an integral part of society, people tend not protest a new one; if they are not the norm, they will. Second, whatever feelings people have about abstract issues like the environment, in practice they react more passionately to immediate rewards and punishments (like a ready parking space) than distant consequences (like the threat of warming).
