At Monday’s High-level Meeting on the Rule of Law, world leaders and Secretary-General Ban Ki-moon reaffirmed that human rights, the rule of law and democracy are interlinked and mutually reinforcing and that they belong to the universal and indivisible core values and principles of the United Nations.

At the High-level Event on Sustainable Energy for All, the Secretary-General explained how the initiative’s success will be measured: “by children newly able to study after dark … mothers breathing healthy air … doctors caring for the sick night and day … businesses seeing new prosperity … a cleaner environment and a path that will help us to avoid the catastrophe of climate change.”

All UN Member States are encouraged to sign or ratify new treaties while in NYC. Here are Monday’s Treaty Event updates: 28 treaty actions were taken by 11 Member States resulting in a total of 9 signatures, 14 ratifications, 3 accessions, and 2 consents to be bound.
