The concept of development has evolved to address a wide range of human needs, including poverty eradication, human rights protection, and environmental conservation. Following WWII, the UN and scientific progress shaped the concept of sustainable development, culminating in the 2015 Sustainable Development Goals. However, the implementation of the 17 UN SDGs is currently hindered by the non-binding nature of international law and the lack of an international judicial system for enforcement. Although the WTO’s role in influencing domestic legislation could potentially advance SDGs, current WTO rules and practices are inadequate for ensuring comprehensive SDG implementation. Efforts to integrate sustainability standards into WTO law, such as the US proposal for actionable subsidies, have not gained widespread support. While WTO provisions like GATT Article XX provide some flexibility for sustainable practices, the overall framework needs reform. This monograph argues for applying a ‘sustainability test’ by WTO panels to align trade practices with the SDGs and examines potential reforms to integrate these changes into WTO rules through a sustainable development club.
