More Greenhouse Gas Emissions Data

One person driving to and from campus from the metro area can emit as much as 78 pounds of carbon dioxide each day, but even employees who live just 10 miles from campus and drive high efficiency vehicles emit approximately 10 pounds of carbon dioxide each day on their commute to work.

This means that reducing greenhouse gas emissions from mobile sources is everyone’s responsibility. For those who live nearby, walking, biking, or taking Northfield Transit can significantly reduce carbon emissions and parking stress on campus. For those living in the metro area, even irregular car or vanpooling can reduce greenhouse gas emissions substantially.

Take a look at the tables below to see how simple behavioral changes in one person’s commuting habits can contribute to solving global climate change.
