On 4 August 2025, the Institute of International Legal Studies (IILS) of the University of the Philippines (UP) Law Center hosted an online forum entitled The Obligations of States in Respect of Climate Change: A Forum on the ICJ Advisory Opinion. The Forum brought together legal academics, international law practitioners, and Philippine government representatives to reflect on the Advisory Opinion (AO) issued by the International Court of Justice (ICJ) on 23 July 2025, which identified the legal obligations of States in tackling climate change.

On March 29, 2023, in a historic move, the United Nations General Assembly adopted Resolution A/77/L.58 by consensus, requesting the International Court of Justice (ICJ) to issue an advisory opinion on the obligations of States concerning climate change and human rights.
 
The Philippines actively participated in the proceedings through the submission of a Written Statement and its involvement in the Oral Arguments.

Launch of the Monograph on the Roundtable Discussion on Examining the Rules-Based International Order (RBIO) from Perspectives in International Law​

Following this roundtable discussion, IILS and DFA are now officially launching the monograph of the discussion.
