Just in time for Earth Day last week, Columbia University pledged to cut greenhouse gas emissions by 35 percent in the next three years through a mix of energy conservation and efficiency measures under its first campus sustainability plan.

The three-year plan, released a day before Earth Day, represents a practical fulfillment of the sustainability principles that university President Lee C. Bollinger announced at the beginning of the academic year. It sets clear targets for shrinking Columbia’s carbon footprint and reducing waste by improving efficiencies in campus operations, boosting composting, recycling and public transit-use, and investing in energy-saving technology.

“At Columbia, we have long understood the profound threat climate change poses to the future of our planet and the role our community should play in confronting it,” Bollinger said. “Through our actions, policies, and behavior, we provide a model for the kind of global response we seek. Most significant in this effort is the basic research conducted by Columbia’s faculty and actively engaged student body working in schools and departments across the University.”

More than a year in the making, the plan was produced with extensive input from students, administrators and faculty scientists—many of them world leaders in the sustainability field. The plan’s overarching goal is to reduce greenhouse gas emissions by zeroing in on energy use and conservation, transportation and waste management.

“Columbia has led pioneering research on the environment, and how our actions will affect future generations,” said Executive Vice President for University Facilities and Operations David Greenberg. “With this plan, Columbia is taking concrete steps to limit our own contribution to climate change. Setting measurable goals and actionable strategies will allow us to track our progress.”
