Prior to the DuPont Co.’s annual shareholder meeting, Friends of the Earth Oceanic Society submitted a proposal requiring the company to (1) accelerate its phaseout of the production of chlorofluorocarbons and halons, (2) present to shareholders a report detailing research and development efforts to find environmentally sound substitutes, and (3) report to shareholders on marketing plans to sell those substitutes. Must DuPont include this proposal in its proxy material for the annual meeting?
