At the invitation of the school’s Eco-Reps program, EO President and co-founder David Poritz visited the University of Massachusetts, Amherst last week as part of Campus Sustainability Day last week. Following a screening of “Oil and Water” at the campus center, Poritz participated in a panel discussion on the university’s fossil fuel use, the Equitable Origin model for linking conscientious consumers to responsible producers, and the fossil fuel divestment movement on campus.
