Calvert’s Social Research Department has recommended that the mutual fund no longer invest in Calpine, due to the company’s aggressive pursuit of geothermal energy at Medicine Lake, a vision-questing area for the Pit River Tribe in northern California. Calvert’s Social Index Committee will act at their quarterly meeting in June on the recommendation to delete Calpine from the Calvert Social Index because the company does not meet the Social Analysis Criteria for Calvert’s progressive indigenous peoples’ rights screen. Calvert Social Investment Fund currently holds 41,000 shares of Calpine. For information contact Calvert’s Director for Corporate Communications, Elizabeth Laurienzo at 301-657-7047.
