In November 1991, following on from discussions at an international symposium on academic freedom, six academic institutions and Science for Peace co-organized a meeting on codes of ethics.

July 9, 2005 marked the fiftieth anniversary of a momentous declaration by eleven eminent scientists, led by Lord Bertrand Russell and Albert Einstein: a warning that the survival of humankind requires the abolition of warfare.

In December 2009 Science for Peace published an open letter on climate change addressed to the Government of Canada. Over 550 Canadian Faculty members signed the letter that called for immediate and drastic reductions in greenhouse gas emissions. The letter pointed out that the time frame of reductions is critical and should be dictated by earth’s physical environment and not by political or short-term economic considerations. The scale is global: climate knows no boundaries; Canada’s emissions harm people everywhere.
