Emergy and Environmental Accounting Workshop

October 17–21, 2022

Corvallis, Oregon and Virtual

Oregon State University's Environmental Sciences Graduate Program is excited to be hosting a live, five day workshop stressing emergy concepts, theory, and principles. Each day is composed of four sessions, two in the morning and two in the afternoon. One or two sessions each day is devoted to a case study that includes “hands-on” computation of emergy or simulation of models to reinforce lecture material and extend understanding of systems concepts.

Cost to Attend
