Dealing with the Challenge of Climate Change within the Legal Framework of the WTO

Although international trade and climate change regimes are two different fields of international law, they are closely interrelated. In particular, certain domestic environmental policies adopted by States may run afoul of WTO law, thereby having adverse effects on free trade. It has been claimed by critics that non-discrimination principles and subsidies regulations of WTO law constrain its Members’ ability to take certain unilateral actions aimed at climate change mitigation. According to other commentators, despite the existence of potential conflicts between UNFCCC and WTO regime, there are still synergies which can be developed to bring a greater coherence, and WTO’s multilateral framework can serve as a vehicle to facilitate targets of the Paris Agreement. This paper argues that although sustainable development is recognized by WTO regime and it leaves some scope for climate change actions, its current legal framework does not provide sufficient space for member’s regulatory autonomy in order to take national regulatory policiesAlthough international trade and climate change regimes are two different fields of international law, they are closely interrelated.
