But in parts of the United States where oil is a significant part of the economy, divestment isn’t discussed. Divestment advocates in Texas have made little progress convincing the state's Permanent University Fund -- which owns mineral rights on more than two million acres of land -- to part ways with oil. Jim Johnsen, the former president of the University of Alaska system, said he can’t remember ever being asked by students or employees about divestment, despite the university’s strong ties to the oil industry. Two members of the University of Alaska system's Board of Trustees have experience working in the fossil fuel sector, and parts of the university system's revenue can be traced back to oil and gas.
