HONOLULU (AP) - The University of Hawaii is studying the possibility of selling off investments in companies that produce fossil fuels. The university's Board of Regents on Thursday appointed a task group to examine the feasibility and desirability of such a move. Board Vice Chairwoman Jan Sullivan is leading the task group, which will suggest actions to the board's budget and finance committee. The panel is expected to meet the university's investment manager, hear from other concerned groups and investigate other public universities' policies. It will make recommendations on divestment by April 30 and on general sustainability policies by June 30. A regent committee heard testimony earlier this month urging the regents to take a strong stand in support of divesting endowment funds from fossil fuel companies.
