Last December, a committee at the University of Toronto released a report on the issue of divestment, drawing a clear line by aligning itself with the needs of the Paris agreement. It recommended that the university not finance companies whose “actions blatantly disregard the international effort to limit the rise in average global temperatures to not more than one and a half degrees Celsius above pre-industrial averages by 2050…These are fossil fuels companies whose actions are irreconcilable with achieving internationally agreed goals.” This principle, basic as it is, aligns rhetoric and action. It suggests that it is all institutions’ responsibility to give life to the Paris agreement. Harvard could adopt this Toronto principle, too, and the world would be better for it.
