In the third episode of our mini-series about Global Commons, we hear from Dr. Megan Blomfield, a senior lecturer in political philosophy at the University of Sheffield. Her research concerns global justice and the environment, focusing on the problem of climate change, which you can read more about in her 2019 book, Global Justice, Natural Resources, and Climate Change. In today’s episode we explore carbon sinks as global commons. Because the issue of climate change concerns how we use and share carbon sinks like the atmosphere, the concept of the global commons has been used to invoke more equitable sharing of carbon sinks. However, Blomfield will show us that this conception isn’t so straightforward when we consider carbon sinks more widely, like land and ocean based sinks.
