Care of humanity and of Earth and its ecosystems is the precondition for both justice and peace. Human beings, creatures, and plants are part of a web of life that depends on Earth for its sustenance. None are on Earth of their own choice. As the most intelligent of living beings, gifted with a moral sense, humans share responsibility to help humans, animals, and Earth itself — its air, water, plants, trees — to flourish. Science, as the instrument of reason, should be dedicated to creating peace and justice, and therefore nurturing life in human societies, among nations, and in nature. This approach stands in opposition to the war and militarism model, and to the market mentality that reduces life to the individual pursuit of material gain. The economy depends for its functioning on Earth’s ecosystems and social systems. Yet unrestrained greed, commodification, and consumerism are destroying ecosystems and rending societies by unjust, unsustainable inequality. Peace, justice, and ecological sustainability are indivisible and science must foster all three. Science for Peace is grounded in these understandings.

Science for Peace was established in 1981, as the final decade of the Cold War began. Its members used knowledge to inform and change public policy. Science for Peace members worked to eliminate nuclear weapons, prevent nuclear war and the weaponization of space, and to convert the military economy. Throughout our history, members have researched, taught, spoken up, and consulted to the government and to the UN. We hold many public meetings and collaborate with and support the work of other groups.

Our past meetings and publications give a picture of the breadth and foresight of our work. From the 1980s, Science for Peace members spoke out on Canada’s weapons trade and its incompatibility with improving global social welfare, on the militarization and environmental degradation of the Arctic and the need to consult with Inuit peoples.

In the 1990s, Science for Peace members focused on disarmament and on the wars and humanitarian situation in the Middle East, the Balkans, Latin America, Indonesia and Africa. Early in our history Science for Peace recognized the economic underpinnings of both climate change and of militarism.


Research is conducted through working groups, as special projects, and on an ad hoc basis.
