International Investment Agreements, Human Rights, and the Path to Net-Zero: What Role for Corporate Codes?

The Paris Agreement's commitment to achieve net-zero greenhouse gas emissions by 2050 has resulted in an uptick in environmental laws and regulations. However, such state conduct could implicate other legal obligations and norms, including international investment law and international human rights law.

It establishes certain principles to guide parties and arbitral tribunals as to the codes while recognizing the inevitable challenges they will face.
