International Treaties, Conventions & Legal Accords

International treaties and multilateral conventions form the primary codified sources of public international law, governed by the Vienna Convention on the Law of Treaties (VCLT 1969) under the principle pacta sunt servanda (treaties must be observed in good faith). Foundational legal accords include the Geneva Conventions (1949), which establish international humanitarian law protecting non-combatants and prisoners of war during armed conflict. Environmental governance is framed by multilateral treaties including the 1992 UN Framework Convention on Climate Change (UNFCCC), the 1987 Montreal Protocol on ozone-depleting substances, and the 2015 Paris Agreement on global carbon emissions. Disarmament frameworks include the Nuclear Non-Proliferation Treaty (NPT 1968) and the Chemical Weapons Convention (CWC 1993).
