Stanford became the first major university to disinvest in fossil fuel industry stocks. It chose to disinvest in the coal industry because burning coal emits the most carbon per unit of energy. Stanford left the door open about disinvestment in other fossil fuel industries.
Stanford's decision was prompted by student activists. Harvard is also being petitioned by students to take similar actions. The action by Stanford may put pressure on Harvard to respond to its student activists. Our elite universities have a moral obligation to display leadership on the issue of global warming.
