About 30 University of Pennsylvania students are staging a sit-in Monday to demand the college divest its endowment of fossil fuel holdings.
"We are sitting in and standing strong," said Megan Kyne, 19, of Pittsburgh, one of the protesters at College Hall.
In a statement, the university said they met with the students on Tuesday to discuss other ways to reduce the school's carbon footprint.
"We are in agreement with them on the importance of this issue. We simply disagree on strategy: they are demanding that Penn divest, and the Trustees have already determined that fossil fuel does not meet the University's criteria for divestment," stated Amanda Mott, spokesperson.
The students brought sleeping bags and intend to stay as long as needed to see their demands are met and are prepared to risk disciplinary action, the group said in a statement.
On March 17, Swarthmore College students staged a similar action. Five of the participants now face possible sanctions.
Zachary Rissman, 20, sophomore from, Summitt. N.J. said the University of Pennsylvania group has met with three administrators.
"They cannot answer us at this time and they will send the message along," Rissman said. Both Penn police and Philadelphia police have visited the lobby where the students are located, he said.
The protesters say they will not disrupt anything of importance and "will respect those who are going about their day," said Rissman.
Climate change affects people more than anything else, Kyne said.
The students want the administration to realize the university carries an additional responsibility because President Trump, who has said he believes the current policies on climate change impede U.S. business growth, is an alumni of the university's Wharton School.
