Campaign Against Arms Trade (CAAT) is a UK-based organization working to end the international arms trade and promote progressive demilitarization in arms-producing countries. The arms business has a devastating impact on human rights and security, holds back economic development, and reinforces a militaristic approach to international problems. CAAT works to expose and document the activities of arms companies, challenge government support for the arms trade, and mobilize the public to take effective campaign action. Each element reinforces the others to help the organization work towards its vision of ending the arms trade.
A 2016 grant from the Cultures of Resistance Network supported CAAT's program of parliamentary lobbying, public campaigning, and legal action towards ending UK arms sales to Saudi Arabia.
