Theorizing the Paris Agreement through a Critical Legal Lens

When it was announced at the UN Climate Change Conference in 2015, the Paris Agreement was welcomed by some in a celebratory mood, while some condemning it as a fail. By the withdrawal of the US, discussions are heated again. As it is scientifically declared the world has entered 6th mass extinction, it becomes more valuable for international lawyers to study on if the Agreement can provide an effective response in combatting with climate change, acknowledging the structural challenges of the international law.
The panellist aims to theorize the Agreement through a critical legal theory perspective by answering such questions: What legal responses does the Paris Agreement provide in combatting climate change? Can it be effective to satisfy its objective when the given structure of international law is taking into consideration? If there are some deficiencies, then how could it be possible to reformulate a more effective legal response to climate change within international law?
