The goal for COP21 was clear—and clearly ambitious: to commit nations to pursue an aggressive path to keep global warming below the 2-degree Celsius threshold agreed by many scientists as critical. Yet the road to implementation remains as difficult as ever. What exactly was committed at Paris in terms of emissions and are we on track to avoid the worst consequences of climate change? What are the major changes to the global energy system required to meet these commitments, and how will those changes be implemented across sectors and by leading emitters such as the US, China, and India? Join The Council on Global Affairs, the University of Chicago’s Energy Policy Institute, and a panel of experts for a review of COP21.
