“The 2015 United Nations Climate Change Conference, held in Paris, resulted in the adoption of the Paris Agreement.”
The claim is directly and unambiguously confirmed by primary institutional sources. The UNFCCC's official COP 21 decisions, the UN Treaty Collection, and multiple corroborating documents all record that the Paris Agreement was adopted on December 12, 2015, at the 21st Conference of the Parties in Paris. The distinction between formal adoption and later entry into force does not affect the claim's accuracy, as it asserts only adoption.
