Neoliberal economics — or really any economic theory — is not going to prevent an apocalypse.
If we can have companies following constructs such as Sarbanes-Oxley then they can most certainly follow the constraints of environmental constructs.
Unless you mean that certain vested interests will bankroll politicians to cut regulation? Then yes, that is a very big problems (see: Koch industries buying their way out of environmental legislation) but not insurmountable.
It’s all got to be on the table and considered though. The entire energy footprint of almost all of the industrial revolution through to current needs to be undone in some way. There’s an inherent requirement on the energy that must be expended in order to do that, by the laws of thermodynamics/physics.
