| Yale's Big Green
Experiment
Imagine a town of
5,500 residents and 21,000 commuters. It has a bus system, power plants, 1,400
science labs, and 1.7 million square feet of office space. It puts out 250,000
tons of greenhouse gases every year.
What happens when a
town like this tries to go green? The bus company lobbies the mayor for more
time. The science labs threaten to move out. The chamber of commerce complains
about costs, and the town council frets about taxes.
Now imagine there's no
town council. There's no chamber of commerce. There aren't even any business owners.
The whole place is run by one man.
And he's just had a
conversion.

Yale's
environmental change of heart was
relatively recent. |
Actually, Levin—Yale's
president—never said that. A lot of people on campus think he did, thanks to a misleading headline in the
online edition of Newsweek. What
Levin did say was more limited, but also significantly more specific: by 2020,
Yale will cut its greenhouse gas emissions down to 10 percent below their
levels in 1990. That would be a 43 percent cut from the levels in 2005. And
there's more. Yale has created an Office of Sustainability and launched a
wide-ranging reassessment of all its operations, in order to make the
university a far greener place.
Yale's
environmental change of heart was
relatively recent.
"At the turn of the
millennium, Yale was not a leader in the area of sustainability," the president
admitted to a gathering of campus sustainability directors in November 2006.
In the first half of
Levin's tenure, which began in 1993, standard practices prevailed. Energy was
cheap, and fuel-guzzling was business as usual. Think of any pre-1960 building
where the radiators get so hot in winter that you have to open the windows, and
you start to get a sense of Yale's large environmental footprint.
Speth, dean of the environment
school and a prominent player in the environmental movement, invited an energy-efficiency
expert to review Yale's practices in 2002; he "basically got stonewalled," the
dean recalls. The next year, the university paid a half-million dollars to settle
state Department of Environmental Protection complaints about the central-campus
power plant. (The complaints were over monitoring and pollution violations;
Yale says they arose from an upgrade that improved energy efficiency and cut
pollution.) At the medical campus's power plant, located in a poor area of New
Haven, it took pressure from City Hall before Yale agreed to switch from a
high-polluting grade of fuel oil to a cleaner-burning, more expensive grade.
And Yale's recycling efforts lagged far behind Harvard's. Part of the reason,
says longtime recycling coordinator C. J. May '89MEM, was that the key step of
collecting paper from people's desk-side bins "was perceived as too expensive."
| |
In the 1990s 18 new buildings went up and 41 more
underwent major renovations. |
Perhaps most
crucially, the university embarked on a massive construction and renovation
program in the 1990s with only a passing thought for energy efficiency and
other green considerations. Eighteen new buildings went up and 41 more
underwent major renovations. In all this construction, energy efficiency was
not made a top priority. True, it's hard to measure the environmental impacts
of that choice. For example, the 2003 renovation of Timothy Dwight College
nearly doubled its energy use, but much of that was probably due to the
installation of air conditioning in common areas—and even the greenest
air conditioning systems are energy sinks.
But one can guess at
the lost opportunities by looking at what Yale is doing now. Today, all new
buildings and renovations have to get LEED (Leadership in Energy and Environmental
Design) certification. Rob Watson, founding chair of LEED, says that "on
average, a LEED-certified green building saves between 30 and 35 percent of the
energy compared to standard code-compliant construction. That's a reasonable
figure" for a ballpark calculation of how much excess energy Yale's renovations
and buildings from the 1990s are consuming, he says. For experienced green
builders, "frankly, it's not that hard," says Watson, now head of New York-based
EcoTech International. "If you're not saving 50 percent or more, you're not
really trying."
Yale
has wised up in its old age: as part of
its 300th birthday celebration in 2001, the university committed to become
greener. Then-provost Alison Richard set up an Advisory Committee on Environmental
Management, composed of faculty, students, and staff. Among its top
recommendations: hire a director of sustainability and create a $1 million
Campus Green Fund to underwrite innovative ideas from students, staff, and
faculty.

Julie Newman describes sustainability as a balance of "ecosystem
health, human health, and economic viability." |
It took a couple of
years, but Yale did both. In 2004, Julie Newman became the university's first
director of sustainability. A new directorship may sound like merely an
additional layer of bureaucracy, but in most bureaucracies, nothing new happens
until someone is put in charge of making it happen. A year later, her work—and
the urgency of the task—had impressed the provost and vice president of
finance and administration enough to create an Office of Sustainability, which
now has four staffers and about a dozen student research assistants (in a
newly, greenly renovated office: see "Everyday Green").
Newman's role is both
far-reaching and, in another sense, highly restricted. She is responsible for
developing sustainability—which she describes as a balance of "ecosystem
health, human health, and economic viability"—in virtually all campus
operations: efficient lightbulbs and waterless urinals one day, ceiling panels
made of recycled newspaper the next. That means Newman needs to understand the
environmental issues involved in areas as diverse as purchasing, cleaning,
transportation, waste management, and building design and construction. Yet she
has no authority over those operations.
"It's not a matter of
going to procurement and saying, 'You have to buy recycled paper.' I have to
build bridges," she says. "I have to get to know what each department does"—and
find ways for sustainability to advance, not impede, its day-to-day goals.
That's a tricky
assignment. "There's a political landscape there that has to be navigated,"
says May, the recycling coordinator since 1990. (Yale Recycling is probably the
university's oldest continuing green project. After years of toiling in the
wilderness, it is enjoying the current burst of interest from the
administration; see page 42.) May thinks that "Julie has rocked the boat just
the right amount. People used to come and ask me—the recycling guy—about
energy. They used to ask me about what kind of paper to buy." Now there are
people focused on those questions full-time. "Solar panels appeared at the
Divinity School and I didn't even know about it. At first I thought, 'Gosh, I'm
out of the loop.'" But then he decided that that's a good thing: so much is
happening that he can't keep up with it all.
The
centerpiece of all the green
initiatives is the carbon reduction project, which Levin announced in October
2005. "It became clear," he recalls, "that this was a major opportunity to step
up and do something significant on greenhouse gas reduction, and to attract a
lot of attention toward these issues. The scientific evidence is widely
accepted that we're on a very dangerous trajectory. But we have a window now
where we can correct it."

Will Yale
agree to green its endowment along with its operations? |
Two years into that
window, Yale has achieved 21 percent of its goal—even as the campus is
projected to expand 15 percent by 2020. (That doesn't count the huge new West
Campus, newly acquired from Bayer Pharmaceutical in nearby West Haven. Its environmental
impact hasn't yet been factored into Yale's plans, but it will be within the
next year.)
There's a long way to
go. And big questions remain unanswered: what happens after 2020? Will Yale
agree to green its endowment along with its operations? How can the university
make sustainability a core value, to be transmitted to students along with
intellectual curiosity and a global outlook?
Still, Yale is in the
midst of a striking environmental transformation. "This was a huge sea change
and an act of very strong leadership on the part of Rick Levin," says Dean
Speth, whom Levin credits as "a constant goad" for better environmental
practices. The kicker, according to Speth: "Rick now gives a better speech on
the climate issue than I do."
Yale
was not the first American university
to establish a concrete carbon-reduction goal, nor has it set the biggest target.
Tufts University was among the earliest; in 1999 it committed to the Kyoto
Protocol's 7 percent cut below 1990 levels by 2012. This year alone, more than
400 college presidents have signed the Presidents Climate Commitment, which
pledges its institutions to take steps toward a goal of climate neutrality.
But Yale drew
international attention when Levin spoke on Yale's global warming goal before
the 2,500 global leaders gathered at the Davos World Economic Forum in January
2007.
| |
Yale expects to meet
its goal for less than 1% of its operating budget. |
"We cannot wait for
our governments to act," Levin told the delegates. "Large organizations with
the power to act independently should take matters into their own hands and
begin to reduce greenhouse-gas emissions now." Among the resulting
international headlines was the one on Newsweek's website that declared, "Yale President Richard
Levin Explains His Plan to Make His University the Greenest in the United
States."
Levin says he never
used that phrase. There's no glimmer of it in the interview itself, a wonky
discussion of Yale's carbon-reduction plan. But the coverage had a profound
effect on campus. "In October '05, people internally didn't understand what we
had just done, to be honest," Newman says. After Davos and Newsweek, they sat up and took notice. (Months after the
headline appeared, one manager interviewed for this article explained that "President
Levin has been very outspoken about wanting Yale to be the greenest campus in
the world.")
Yale expects to meet
its goal for less than 1 percent of its operating budget. "If everyone around
the world had to pay one-half of 1 percent of income to save the world from overheating,"
Levin observes, "most would think it a small price to pay."
Some changes are
highly visible, like campaigns to get undergraduates to unplug their electronics
before vacation. Others, like saving energy by reducing the air-change rate in
labs, are invisible. Some changes are dramatic, like the environment school's
cutting-edge Kroon Hall (see "Building for Keeps"). Others are as mundane as compact fluorescent
lightbulbs. Cutting energy use due to Yale's enormous construction and
renovation campaign is key. The university is developing its own sustainability
standards for building design and construction, but Levin has also made a
specific commitment that "we are going to seek LEED certification for every one"
of the new campus buildings and renovations.
Yale started with
high-impact projects—those that get the biggest carbon bang for the buck—such
as buying some of its electricity from a Midwest producer of wind energy. Now, "I
think we're getting into the more difficult things," says John Bollier,
associate vice president for facilities operations. "They get more
capital-intensive." And, sometimes, more environmentally complicated.

Carbon offsets are traded as credits on the open market. |
For instance,
geothermal heating and cooling systems—in which water from underground is
cycled through a building as a heat transfer medium then returned to the earth—"are
a lot more effective" than solar panels, Bollier says. But using groundwater
means that special attention must be paid to monitoring the condition of the
aquifer below, which leads to other concerns—such as how much of the
campus is covered with impervious paving. Like others before him, Bollier has
found that in environmental planning, "you pull on a string and it leads to a
lot of other things."
Yale also plans to buy
carbon offsets—that is, to balance some of its carbon emissions on campus
by paying someone else to cut an equal amount of carbon (by planting trees in
tropical forests, say, or installing scrubbers on a power plant in China). Such
offsets are traded as credits on the open market. But it can be hard to tell
whether they're working. "There's a lot of greenwashing going on in the
marketplace," Bollier says. Yale might end up "just lining somebody's pockets
with profits" for projects that would get built whether Yale helped fund them
or not.
Bollier wants Yale's
offset money to produce new, and verifiable, energy savings or renewable
energy. He's exploring programs by which Yale offsets would encourage faculty
and staff to reduce their own carbon footprints. Next spring, for example, the
university will launch a pilot program to subsidize mass transit for employees.
"Wouldn't it be great,"
he asks, "to improve the air quality in New Haven, as opposed to some remote
project that was going to happen anyway? We're trying to channel people's
creativity."
One
major carbon source hasn't even made it
into Yale's greenhouse gas plan yet: the almighty automobile.
The university created
a new position, director of sustainable transportation, and filled it in April
by hiring the aptly named Holly Parker. "Yale is running out of parking," she
says. "Part of my job is to encourage people not to bring their cars here."
| |
Nobody
knows how many Yale employees commute by car. |
At this point, nobody
knows how many Yale employees commute by car or how much carbon they put out.
Parker is charged with cutting, by a yet-to-be-determined amount, the number of
single-occupancy cars coming to campus. She'll start this fall, with an
employee survey to find out how people get to work and what it would take to
make them stop driving alone. Parker will use that data to estimate the
greenhouse gas impact of Yale commuters—a number that Yale will plug into
its overall carbon-reduction goal. She'll also use the survey results to
concoct incentives. Subsidies for train or bus fares? An enhanced carpool
program? Showers and lockers for bicyclists, plus better bike storage? All of
these are under consideration, as well as, potentially, a telecommuting policy.
One change has already arrived: Zipcar, a company that offers inexpensive,
hassle-free car rentals by the hour, installed a fleet of six cars at Yale in
September. Now carpoolers and mass-transit users have access to cars on campus
when they need them.
It may take all those
enticements and more to get people to stop driving to work alone. At Harvard,
where Parker worked previously, "it took six years to reduce the rate by 10 percent,"
she says. "Driving alone to campus was a really good solution for a long time.
It's only recently that that has changed, and it hasn't changed perceptibly."
Ask Brenda Naegel. As
associate director of communications and training for Yale procurement, she is
passionate about green purchasing. "I've always been a nature girl," she says. "I've
been recycling for as long as I can remember. I've greened my food and my
cleaning products. But I still drive my car to work"—45 miles a day, five
days a week.
Some
people make the case for stronger
action by Yale. The Sustainable Endowments Institute issued a College
Sustainability Report Card this year. Yale got straight As in all the
operational categories. But because it doesn't reveal its endowment holdings
and doesn't screen investments for environmental impact, it pulled a C for
investment priorities and a D for endowment transparency. Its overall grade was
B+.
Levin shrugs it off
with a chuckle. "We're probably going to stay at B+ overall," he says. "I'm
happy to get As in all the practical areas. But to actually tilt your portfolio
through screens that advance a social agenda—whether it's civil rights or
anything else—we haven't done that, and we don't plan to."
| |
Yale has "a stellar reputation" on environmental
matters. |
Even on climate
change, where Yale has the most bragging rights, the university comes in for
some criticism. The co-chairs of the Yale Student Environmental Coalition have
called on Levin to add his name to the American College and University
Presidents Climate Commitment. Gus Speth believes Yale should sign "in the near
future." But Levin says the pledge lacks specifics. (In fact, it contains no
dates or numeric targets. It does require signatories to choose two steps from
a list of seven, such as meeting LEED standards and providing access to public
transit.) By signing the pledge, "all you're doing is advertising yourself as
supportive of fighting global warming, without any meaningful commitment," he
says. "I believe in making commitments that I can honor."
Anthony Cortese,
co-coordinator of the Climate Commitment and a Massachusetts-based consultant
on campus sustainability, says Yale has "a stellar reputation" on environmental
matters. Nonetheless, he thinks Levin should sign the pledge. "I think
sometimes the more elite schools think that they don't have to join efforts cooperatively
with other schools," Cortese says. "The effort to get to climate neutrality is
such a huge effort that all the schools need to collaborate."
In the end, though,
Cortese believes that operational green-campus efforts pale compared to a
university's core business. "Ultimately, the impact of higher education is
education," he says. "The most important thing is: all the graduates who come
out, give them the training and education that will allow them to carry out
their professional goals in ways that will result in environmentally
sustainable behavior. Because that's the only kind of behavior that will allow
people to progress."
