The Paris Agreement was the culmination of more than 20 years of negotiations. It represents a consensus among 195 governments on what the global regulatory framework for preventing climate change post-2020 should look like. Agreement also sends a strong signal on political ambition, and has integral mechanisms aimed at increasing ambition over time. From an international law perspective, the Paris agreement consolidated an architecture for multilateral climate governance. The article examines whether the Paris Agreement provides the necessary global regulatory mechanisms to prevent climate change. This article looks at what difference, if any, the Paris Agreement will make for the energy sector. How can an agreement that does not make a single reference to fossil fuels, nor any substantive reference to energy, push countries to decarbonize their energy supply and move towards more efficient and climate-resilient energy systems.
