In order to limit climate change, many governments and companies have announced targets of “net zero” greenhouse gas emissions (GHG) by the year 2050. What does “net zero” really mean? Is it an appropriate and sufficient goal? Is this goal attainable with continuing economic growth, or should we be looking at “degrowth”? And what about 2030 - are the reductions in GHG promised by Trudeau and other countries feasible? This study group will explore recent and upcoming developments in efforts to stop global warming, in the light of the November 2021 COP 26 and recent reports from the Intergovernmental Panel on Climate Change and the International Energy Association.
