Carbon Footprint Analysis of Danforth Campus Students at Washington University

This report delves into the carbon footprint of Danforth Campus students at Washington University, examining energy consumption, transportation emissions, and campus infrastructure from 1990 to 2007. It highlights the significant trends in carbon emissions, with a 70% increase attributed to buildings and transportation, while emissions from student commuting have decreased. The analysis utilizes a causality framework to establish relationships between various factors influencing carbon output. This comprehensive study aims to inform sustainability initiatives for reducing the university's carbon footprint.
