Countries can work together better on fighting climate change by creating smaller groups called climate clubs that collaborate via international trade. The big issue is the struggle for global agreement on climate actions. Climate clubs, made up of willing nations or organizations, can drive more effective change. By using international trade systems, these smaller groups can push for sustainability goals without needing unanimous consent from many parties. This approach challenges current multilateral agreements and suggests more flexible, targeted efforts could lead to greater success in climate change mitigation. The study argues that shifting focus towards international trade can help produce real results in fighting climate change. The key takeaway is that by forming climate clubs and leveraging trade mechanisms, global efforts to address climate change can be more efficient and impactful.
