With Valentine's Day approaching and matters of the heart on the mind, now might be a good time to take stock of your relationship by considering another individual's needs: Mother Earth's. In the Green Room piece republished below, Barron YoungSmith explains why long-distance relationships are bad for our planet.
You're sitting in the airport terminal, rolling your copy of the Economist into a sweaty tube and waiting to see a significant other who lives far away. You're excited. You're aroused. But there's something else, a nagging feeling that gurgles in your stomach and won't go away. Is it pangs of guilt? It should be: The planet is about to suffer for your love.
Perversely, we live in a world where the sustainability consultant in San Francisco is willing to fly in an exotic boyfriend every month from Washington, D.C. All day, she helps companies "green their supply chains" and "internalize core social costs," yet that eco-savvy seems to vanish at night, when she e-mails: Come visit!!! You might say she's willing to be a locavore but not a locasexual.
Consider what happens when these two fly to see each other once a month. Since greenhouse gases emitted from high-altitude airplanes are thought to have several times the impact of ground transport, a carbon offset company would pin their romantic travels with the equivalent of 35 metric tons of CO2 each year. If that responsibility were divided evenly between the two, our sustainability consultant's lifestyle would be about six times worse for the environment than that of the average gas-guzzling American—and up to 10 times worse than that of the average San Franciscan. (Indeed, for her, breaking up would be about 10 times better for the environment than going vegetarian.)
Or let's say she finagles a transfer to New York, so she can be within driving distance of her sweetie. Now the happy couple can see each other every couple of weeks—while their long, solo trips down I-95 spit out an extra 3.6 metric tons of CO2 every year.
What's the aggregate impact of all this travel? The Census tells us there are about 100 million single people in America over the age of 17. We don't know how many of those folks are in long-distance relationships, but the available research suggests that at least a quarter of all college students are dating out of town. Since the rate is going to be much lower among the general population, we'll make a conservative estimate of 1 in 15 for all single adults. That gives us around 6.7 million unmarried Americans in long-distance relationships. Add in the 3.4 million married people who told the Census that they live separately but aren't "separated," and our total rises to more than 10 million individuals—or 5 million LDRs.
If all of these people made like our two-career couple and drove the distance from D.C. to New York City every two weeks, they would produce a total of about 18 million metric tons of CO2 a year. For comparison, 6.9 million metric tons would be added to the atmosphere if we suddenly eliminated all the public transportation in the United States. Eighteen million metric tons of CO2 is a third of what a national renewable energy standard (PDF) would save over 10 years—or 60 percent of the yearly emissions saved by "moderate adoption" of hybrid vehicles. And if even a small percentage of those relationships were bi-coastal—or even New York-Chicago or Los Angeles-Denver—the total would grow even more astronomical. Love lifts us up where we belong, as they say, but it does so at a steep price to the planet.
The same type of environmental logic has already been applied to our eating habits. The Local Food movement encourages us to cut CO2 emissions by calculating food miles—the distance a meal travels from production to the dinner table—and eating only what's produced within a 100-mile radius. Isn't it time for a Date Local movement, too? Let's start thinking about "sex miles": Just how far was this person shipped to hook up with you? And how manytimes more efficient would it be to date someone within a 100-mile radius? If the movement spread globally, mirroring either the decentralized development of Local Food co-ops or the manifesto-and-chapter model that built up to the Slow Food movement's mega-confab this summer, its environmental benefits could multiply many times.
