Net zero by 2050 is a driver for a lot of the analysis we're doing right now. Of course, there are a number of different pathways that can get you to net zero. Related to that is what the definition of net zero is. There are a number of definitions out there, both within the Intergovernmental Panel on Climate Change, the UNFCCC and other academic approaches. In general terms, it's emissions minus removals. Removals can be from natural sources like trees and soils. It can be from technological sources, like carbon capture and storage technology or direct air capture. It could even potentially be minus offsets, such as emission reductions achieved elsewhere.
