Soft, complex, and fragmented international climate change practice: what implications for international trade law?

Climate change presents a global challenge because it affects all countries – albeit in different ways 1 – and because it requires efforts from all members of the international community – albeit with unique approaches. 2 The global nature of dealing with the increase in greenhouse gas (GHG) emissions and corresponding climate change necessitates, hence, an international response capable of uniting all countries. Has this happened? Is this likely to happen in the near future, or in the long term? And what are the implications if this collective action does not take place?
