If you’re listening to this, you’re probably familiar with the term “net zero,” commonly defined as a state in which greenhouse gases emitted into the atmosphere are balanced out by those removed.

But is it that simple – or even true? What’s the role of emissions reductions and offsetting in helping us achieve such a balance? Have humans ever had a net-zero relationship with the climate?

In the last episode of our GLF Live mini-series of “climate crash courses,” we’re joined by Kate Dooley, a renowned expert on climate mitigation and land-use, to explore the concept of net zero and how its real meaning can be achieved – if it can be achieved at all.
