For this specific case it means net zero carbon emissions into the atmosphere. Plastic isn’t carbon in the atmosphere, so it isn’t included in these figures.

Net zero is just the first step anyway. Once we reach net zero, we still need to work really hard to get to actual zero, then we still need to find a way to be significantly carbon negative if we want to try to slow the worsening rate of climate related disasters.

Hopefully, somewhere in that process, oil products will become non-viable.
