Over the course of the 2010s, the term “net-zero carbon emissions” migrated from climate science to climate modeling to climate politics. Today, it is ubiquitous in the climate world — hundreds upon hundreds of nations, cities, institutions, businesses, and individuals have pledged to reach net-zero emissions by 2050. No one ever formally decided to make net zero the common target of global climate efforts — it just happened.The term has become so common that we barely hear it anymore, which is a shame, because there are lots of buried assumptions and value judgments in the net-zero narrative that we are, perhaps unwittingly, accepting when we adopt it.Holly Jean Buck has a lot to say about that. An environmental social scientist who teaches at the University at Buffalo, Buck has spent years exploring the nuances and limitations of the net-zero framework, leading to a 2021 book — Ending Fossil Fuels: Why Net Zero Is Not Enough — and more recently some new research in Nature Climate Change on residual emissions.Buck is a perceptive commentator on the social dynamics of climate change and a sharp critic of emissions-focused climate policy, so I'm eager to talk to her about the limitations of net zero, what we know and don't know about how to get there, and what a more satisfying climate narrative might include.
