Straining between remnants of the old paradigm and integration into the new.

If you want to save the planet, think for a minute about the simple plastic cup. Eight or 12 ounces, perhaps emblazoned with a Princeton logo — the University goes through thousands of them each month.

At PEI we are approaching 2010 with a fresh sense of optimism. The Institute is strong and vital, as this issue of PEI News clearly illustrates.

Filling the ENV lab to capacity, students were eager to learn about the environmental studies program.

When the more than 100 students completed internships this summer, they had at least one more commitment.

On June 1, 2009, PEI held it's 15th annual Class Day celebration.

A summary of the University's many campus sustainability initiatives.

Barmeier is among the 32 American college students who won the prestigious fellowships, which fund two or three years of study in England.

In its first report since adopting a Sustainability Plan in February 2008, Princeton University states that on-campus greenhouse gas emissions have decreased for the first time since the University's energy-efficient cogeneration plant was installed in 1996.

At the moment, the roof above Dormitory A of the redeveloped Butler College complex is a "green" roof only in the most technical sense of the phrase.

The new dormitories at Princeton University are already covered in green -- but not the traditional green ivy of the Ivy League.

The second round of initiatives seeking to improve sustainability on Princeton's campus have been funded under the auspices of the University's Sustainability Plan.

Ask Princeton ecologist David Wilcove about the largest threat to the greatest number of species in the next 25 years, and he'll give you a two-word answer. Global warming? No, oil palm.

The project incorporates many sustainability features, including green roofs on more than half of the buildings.

In one corridor, a faculty member was having an animated discussion on the future of the oil supply with two students. At a table, a Dining Services staff member was helping a local high school student with a project on recycling. Behind a bicycle that powered a light bulb, a student organization officer was signing up a new member.

A small experiment in organic gardening last year has blossomed into a large plot of vegetables and herbs this summer with nurturing from a group of dedicated students, the Office of Sustainability and other departments, and the High Meadows Foundation.

You have to love nature, rising junior Stephanie Hill said, when you grow up, as she did, in a remote, pristine village on the shores of a glacier-fed lake in British Columbia.

The first round of initiatives has been funded under the auspices of the research, education and civic engagement section of the University's new Sustainability Plan.

For the second consecutive year since adopting a Sustainability Plan, Princeton University's on-campus greenhouse gas emissions have decreased.
