As they consider how to ratchet up their campaign, the students suddenly find themselves at the vanguard of a national movement.
In recent weeks, college students on dozens of campuses have demanded that university endowment funds rid themselves of coal, oil and gas stocks. The students see it as a tactic that could force climate change, barely discussed in the presidential campaign, back onto the national political agenda.
“We’ve reached this point of intense urgency that we need to act on climate change now, but the situation is bleaker than it’s ever been from a political perspective,” said William Lawrence, a Swarthmore senior from East Lansing, Mich.
Students who have signed on see it as a conscious imitation of the successful effort in the 1980s to pressure colleges and other institutions to divest themselves of the stocks of companies doing business in South Africa under apartheid.
A small institution in Maine, Unity College, has already voted to get out of fossil fuels. Another, Hampshire College in Massachusetts, has adopted a broad investment policy that is ridding its portfolio of fossil fuel stocks.
“In the near future, the political tide will turn and the public will demand action on climate change,” Stephen Mulkey, the Unity College president, wrote in a letter to other college administrators. “Our students are already demanding action, and we must not ignore them.”
But at colleges with large endowments, many administrators are viewing the demand skeptically, saying it would undermine their goal of maximum returns in support of education. Fossil fuel companies represent a significant portion of the stock market, comprising nearly 10 percent of the value of the Russell 3000, a broad index of 3,000 American companies.
No school with an endowment exceeding $1 billion has agreed to divest itself of fossil fuel stocks. At Harvard, which holds the largest endowment in the country at $31 billion, the student body recently voted to ask the school to do so. With roughly half the undergraduates voting, 72 percent of them supported the demand.
“We always appreciate hearing from students about their viewpoints, but Harvard is not considering divesting from companies related to fossil fuels,” Kevin Galvin, a university spokesman, said by e-mail.
Several organizations have been working on some version of a divestment campaign, initially focusing on coal, for more than a year. But the recent escalation has largely been the handiwork of a grass-roots organization, 350.org, that focuses on climate change, and its leader, Bill McKibben, a writer turned advocate. The group’s name is a reference to what some scientists see as a maximum safe level of carbon dioxide in the atmosphere, 350 parts per million. The level is now about 390, an increase of 41 percent since before the Industrial Revolution.
Mr. McKibben is touring the country by bus, speaking at sold-out halls and urging students to begin local divestment initiatives focusing on 200 energy companies. Many of the students attending said they were inspired to do so by an article he wrote over the summer in Rolling Stone magazine, “Global Warming’s Terrifying New Math.”
Speaking recently to an audience at the University of Vermont, Mr. McKibben painted the fossil fuel industry as an enemy that must be defeated, arguing that it had used money and political influence to block climate action in Washington. “This is no different than the tobacco industry — for years, they lied about the dangers of their industry,” Mr. McKibben said.
Eric Wohlschlegel, a spokesman for the American Petroleum Institute, said that continued use of fossil fuels was essential for the country’s economy, but that energy companies were investing heavily in ways to emit less carbon dioxide.
In an interview, Mr. McKibben said he recognized that a rapid transition away from fossil fuels would be exceedingly difficult. But he said strong government policies to limit emissions were long overdue, and were being blocked in part by the political power of the incumbent industry.
Mr. McKibben’s goal is to make owning the stocks of these companies disreputable, in the way that owning tobacco stocks has become disreputable in many quarters. Many colleges will not buy them, for instance.
Mr. McKibben has laid out a series of demands that would get the fuel companies off 350.org’s blacklist. He wants them to stop exploring for new fossil fuels, given that they have already booked reserves about five times as large as scientists say society can afford to burn. He wants them to stop lobbying against emission policies in Washington. And he wants them to help devise a transition plan that will leave most of their reserves in the ground while encouraging lower-carbon energy sources.
“They need more incentive to make the transition that they must know they need to make, from fossil fuel companies to energy companies,” Mr. McKibben said.
Most college administrations, at the urging of their students, have been taking global warming seriously for years, spending money on steps like cutting energy consumption and installing solar panels.
The divestment demand is so new that most administrators are just beginning to grapple with it. Several of them, in interviews, said that even though they tended to agree with students on the seriousness of the problem, they feared divisive boardroom debates on divestment.
That was certainly the case in the 1980s, when the South African divestment campaign caused bitter arguments across the nation.
