What To Do with an Old Gas Guzzler


Judith Warner's New York Times blog, "Domestic Disturbances," has a very funny posting on the family's Land Rover, which now sits in the garage except for trips to the local Metro stop, the supermarket, and the gas station—all less than a mile each way.

Warner's speculations about the ways the family might actually use the Land Rover in future are hilarious. A good, short read with a serious point lurking among the laughs.

The Annotated G8 Statement

In contrast to 2007, when the Group of 8 failed to reach agreement on cuts in greenhouse gas emissions, the G8 Summit this year issued a statement calling for a 50% cut in greenhouse gas emissions by 2050. This sounds important, but in fact the situation is not much different from 2007. The goal for cuts is too small, the statement is not binding on member nations, and the agreement does not include emerging polluters China and India. What seemed like a start, however inadequate. turns out on a close reading to be lacking in both substance and force.

Andrew Revkin's New York Times blog, DotEarth takes an extended look at the statement, with an annotated version and a critical analysis. Well worth reading.

Hip Deep in the Big Muddy


It is curious how much two disasters can have in common.The most recent, the midwestern U.S. flood of 2008, is an affliction on a scale that is difficult to comprehend. The second, much smaller but catastrophic nonetheless for those affected, is the almost annual river flooding in Bucks County, PA.

The common element for both is the way that misguided (or nonexistent) land use planning helped pave the way for calamity.

Joel Achenbach, a staff writer for the Washington Post, presents impressive evidence that a combination of farming and residential development on flood plains, wetland drainage, and manipulation of the water table contributed to the flooding and very likely made it more severe than it might otherwise have been. Without heavy spring rains, there would have been no flood. But even with them, human mistakes had helped to prepare the way for the catastrophe that did in fact happen.

It would be unfair to blame the farmers for the disaster. Farming is a hard, precarious profession. Farmers have little choice: they must grow what is profitable, and they need land to grow it on, even if that land is a wetland that should never have been drained.

Developers who build on flood plains and create subdivisions from farms bear some responsibility—but not all. The American style of residential development is based on profligate use of the land, but land use decisions, like decisions about draining wetlands, are matters of public policy. Better policies might have saved enough wetlands and farmland to make a difference.

The best way to minimize floods and their human consequences is thoughtful, informed land use planning. If our planning is flawed or—as is sometimes the case in the U.S.—we have no effective planning mechanism at all, there will be consequences. And those who pay will seldom be those who made the policies.

Consider the plight of riverside residents in Bucks County, Pennsylvania. For years, going back to the 1950s, local governments in Bucks County have been helping the county's economy to grow by approving projects that pave over land for shopping malls, destroy local farms to build suburban subdivisions, and put parking lots almost literally everywhere in the county. This has meant problems with water runoff, which in turn has made flooding on local rivers more likely—and entire towns close to the rivers have suffered.

In Iowa, Missouri, Wisconsin, and, on a smaller scale, Bucks County, residents are suffering because in the United States we have traditionally regarded land use planning as suspect. We must do better in the future.

The Fuel Price Follies

Everybody in the United States is in a lather about fuel prices. Airlines are scrambling: they are cutting service (for which read personnel), charging for services that once were free, and passing fuel surcharges through to customers, just to avoid losing money. Two of the three candidates for U.S. President advocated a summer Federal gas tax "holiday" which, economists universally pointed out, would not save consumers any money and might raise the price of gasoline in the long run. Automakers like Chrysler, suddenly unable to sell the SUVs and trucks that had become their staple, are now offering protection from gas price increases. Finding the best gas price has, in fact, become a cottage industry, with new Web sites springing up every day.

Little of this is surprising. Americans have lived with cheap transportation fuel for so long that life without it is inconceivable to many. Worse, we, more than any other developed country, are unprepared for fuel costs which, in the long run, will go up, not down. We fly and drive everywhere, and until recently, fuel economy (let alone the effect on the planet) was not a factor in planning and transportation decisions. Now we have few alternatives, and our failure to provide them will make the transition to a future of fuel economy and high fuel costs that much more painful.

Consumers, showing more common sense than many politicians, have begun leaving their cars at home, consolidating car trips, and using public transit, according to a recent Washington Post report. The increase in ridership in Philadelphia is somewhere between five and 10 percent—not enough to bring our fossil fuel usage down significantly, but enough to show a trend that could do this if it keeps up. The problem is that our public transportation, both here and in the rest of the country, is not ready for the increases in ridership that will (and should) come as fuel costs remain high.

Politicians and policy-makers still don't quite get it. Conservatives suggest that oil prices are experiencing a speculative bubble, and prices will go down as market forces act—all of which could be true but would not prevent higher prices as oil becomes more scarce and harder to extract. Liberals attack the oil companies for enormous profits—which they certainly have made in the past few months. The problem is that attacking the oil companies will not prevent oil from become harder to find because there is only so much oil in the ground in the first place. To adapt to a future of expensive oil, we have to stop living as if cheap fuel is a human right. This means investment in old infrastructure like railroads, and new ideas like light rail and alternative energy. Many politicians, however, still insist that building roads is an investment, while funding public transit is a subsidy.

A future with cheap oil is not on offer. Nor, unless we want the earth to become uninhabitable, is a future based on massive use of fossil fuels. Whether we can get to a future that is not based primarily on fossil energy is the central question of our age. We will not do so by giving ourselves gas tax holidays, inveighing against the oil companies, or deceiving ourselves about the nature of the problem.

Climate Change Bill Likely to Reach Senate Floor

The Lieberman-Warner Climate Security Act will mark the first time that a climate change bill has been debated in the Senate since 2005. Kate Sheppard of Gristmill gives a good summary of the bill, its history, and its strengths and weaknesses. It is not the strong bill that we need, but it at least acknowledges that there is a problem. Sheppard's lucid summary is well worth reading.

Postscript June 11: Threats of a filibuster by opponents of the Climate Security Act prevented the bill from reaching the Senate floor.

The Virtues of Age

We live on a block and in a neighborhood full of old houses. Most of the houses on our block have three stories; some, like ours, share a wall with another house. Others stand alone. The houses around the corner are all classic Philadelphia row houses—one of the most efficient house designs ever devised.

On our block, the houses differ in design, in distance from the street, and in other ways, but they have much in common. They are not large by modern standards; our house is about 1,575 square feet, much smaller than a typical McMansion (3,000 square feet). None has a garage, although the house next door has a converted carriage house that can shelter a car. All have entrances that face the street and welcome visitors. All have small front gardens.

It is not an exercise in nostalgia, but the literal truth, to say that no one builds houses like these today. In an exchange of letters on suburban housing in a recent Atlantic Monthly, a builder pointed out that because the market favors large houses, developers must economize on material and methods in order to make a profit. For instance, they use sheetrock instead of lath and plaster, and molded plastic windows and trim, because these save money. For a smaller house, fewer shortcuts might be necessary.

More to the point, during the 1950s, 1960s, and 1970s, no one built neighborhoods like the ones that are common in cities. There is a good vegetable store on the corner of our street. Within easy walking distance one can find two drug stores, a hardware store, two supermarkets, a pizzeria, a library, five schools, several medical and dental offices, and two veterinary offices.

Suburban developments have no corner stores, walkable shopping streets, or local schools within half a mile of where students live. They have distant supermarkets and big box stores, shopping malls, and consolidated schools, none accessible to most residents without a car. Hence the two or three-car garage which dominates many modern houses and inevitably raises every family's carbon footprint when they drive to the mall or to school.

The suburban way of life, so dependent on cheap fuel, is nearing the end of its viability. Architects and planners like the New Urbanists are designing walkable neighborhoods modeled on blocks like mine. One does not have to agree with all of New Urbanism to see that they are on the right track. We must live in smaller, more efficient houses, and we need to be able to walk, not drive, to neighborhood amenities.

This is not a radical change, though in a world full of suburban development it may seem so. We already have neighborhoods like this in our cities. The stereotype of the city—that its people are either very poor or very rich—has just enough of the truth to be credible. But it is not the whole story. Many city neighborhoods, like my block, are affordable, pleasant places to live. In the future, we will need more such places.

Toronto's Greenbelt Leads the World

Urban sprawl—the uncontrolled growth of automobile-driven suburbs—has increasingly been recognized as a form of blight. It destroys vital farmland to create tract house developments miles from work, shopping, and even good walking areas. Suburban shopping districts cling to the edges of the highway, each store with its own parking lot, or close themselves from the outside world in shopping malls surrounded by the inevitable acres of asphalt for parking. Sprawl is an offense to the eye, the aesthetic sense, and the planet.


One proposed solution to the sprawl problem is the creation of greenbelts, areas of land closed to development and protected for agriculture, parks, and wildlife. The largest and most creative of these, according to a study reported in the April 9, 2008, Globe and Mail, is the greenbelt surrounding Toronto.

"Ontario's greenbelt is positioned to be the most successful and most useful greenbelt in the world," concluded the study, compiled by the Canadian Institute for Environmental Law and Policy, a Toronto-based think tank.

Commissioned by the Friends of the Greenbelt Foundation, the study compared Toronto's greenbelt with similar efforts in Canada, England, and Europe.

According to the report, greenbelts face at least two major problems: pressure for development, and "leapfrogging" of sprawl over the greenbelt.

So far, the province of Ontario has resisted pressure from developers to open the Toronto greenbelt to sprawl.

"My goal and my mantra that drives me is that we're going to be doing nothing but expanding the greenbelt," Municipal Affairs Minister Jim Watson said in an interview [with the Globe and Mail.]

To avoid "leapfrogging," Ontario authorities hope to expand the greenbelt, in effect doing the opposite of opening the protected land to development.
