Dr. Philip Sirianni (Department of Economics, Finance, and Accounting) has published a research paper titled “Carbon Efficiency of U.S. Colleges and Universities: A Nonparametric Assessment,” with Dr. Michael O’Hara (Department of Economics, Hamilton College). The work appears in the journal Applied Economics. The authors use greenhouse gas emissions data reported under the Presidents’ Climate Commitment ( and a nonparametric data envelopment analysis to evaluate the relative environmental performance of the commitment’s signatories. The authors find that while many institutions are producing their current levels of desirable outputs (teaching and research) efficiently in terms of their carbon emissions, there still exists considerable variation in efficiency and potential for improvement. Additionally, they find evidence for both efficiency and technical change over time, although this evidence comes primarily from teaching-focused institutions.
