Rio+20 was held in Brazil and was the research team’s third CEE. Dr. Corson and five Mount Holyoke College women initiated a pilot project to involve undergraduate students in CEE, and by following the preparatory process for 15 months, they expanded the CEE method to capture not just the event itself, but also interactions over time. At Rio+20, team members worked in sub-teams focused on rights-based resistance to market-based conservation, oceans and corporate sustainability.
