Request for feedback: 2030s Net Zero Playbook and CDR appendix

[Shannon Fiume]

Hi,

Recently, I completed the 2030s Net Zero Playbook: https://bit.ly/NZpbk

The playbook is intentionally high-ambition and was developed with AI assistance from ChatGPT, under my full editorial control. I understand that its accelerated timeline and AI-assisted development process will invite skepticism, so I am especially interested in substantive review.

The core finding is that achieving net zero fast enough is not only a clean-energy scaling problem. It is a synchronization problem: infrastructure, finance, adequacy, workforce, fossil retirement, new demand, and biosphere resilience all have to move together so clean growth results in actual fossil displacement rather than parallel clean and fossil systems.

The playbook argues for the fastest institutionally plausible path to the smallest residual net zero, with fossil phaseout completed in parallel so any future CDR burden is minimized and can ultimately be powered by renewable systems.

I’m looking for feedback, critique, or peer review on the report. If your feedback is about the net-zero framework, feel free to contact me directly or comment on the document. If your feedback is specifically about CDR, I’d welcome discussion in this thread.

Additional relevant sections include the four system rules and net-zero definition in the introduction, Chapters 11–12 on biosphere and managed land systems, Chapter 1 and Appendix D on workforce, and related references to MRV.

Shannon Flume,

Professor Simon Michaux sees not enough critical metal ores minable for the Net Zero transition: https://tupa.gtk.fi/raportti/arkisto/42_2021.pdf

Has that been estimated by your team?

Brian

Hello Shannon,

Apologies, I'm just getting to this. Let me look it over a bit early this week.
