Why Net Zero (and what is it)? 'COP Conversations' Series.

Net zero refers to a state in which the greenhouse gases going into the atmosphere are balanced by removal out of the atmosphere. The term is important because – for CO2 at least – this is the state at which global warming stops. Global warming is proportional to cumulative CO2 emissions, which means that the planet will keep heating for as long as global emissions remain more than zero. This implies that climate damages, caused by global heating, will continue escalating for as long as emissions continue.
But all is not lost! Oxford has several researchers working in this area, and one of our key voices is today’s speaker, Sam Fankhauser, Professor of Climate Change Economics and Policy at the Smith School and Research Director of Oxford Net Zero.
