Global CO2 emissions will peak this decade — but decline will be far too slow for 1.5°C?

Timeline A · Peak Too SlowReality
85%
Crowd 55%Gap 0

CO2 emissions peak between 2030 and 2032, then flatten or decline slightly through the decade's end. The peak happens because renewable energy deployment accelerates in China, India, and the EU; coal use plateaus in developed nations; and electric vehicles capture 40-50% of new car sales globally. But the decline is shallow—maybe 2-4% below peak by 2032—because global energy demand keeps growing, cement and steel production expands in developing economies, and carbon capture technology remains marginal. The world crosses 1.5°C warming before emissions fall fast enough to matter.

Timeline B · Faster DeclineReality
15%
Crowd 45%Gap 0

Emissions never definitively peak this decade; instead, they keep climbing through 2032, possibly with minor year-to-year dips that look like peaks but reverse. Coal demand stays strong in India and Southeast Asia; oil consumption from transport and aviation grows faster than electric alternatives scale; and policy commitments fail to translate into actual emission cuts at the speed promised. The stated-policy scenario (what governments claim they'll do) diverges sharply from real-world emissions, and by 2032, we're still on a path toward 2.5-3°C warming.

The quiet paththe one nobody’s watching

Geopolitical shock or climate cascade forcing emergency energy mobilization overrides both scenarios.

The read
Reality still leans toward Peak Too Slow.

Reality favors Peak Too Slow — the pressures holding that outcome in place are stronger than the counter-pull. The main thing that could shift this is China coal-and-renewables trajectory.

The movers, ranked by leverage

01
Collective pull shiftMarket-class: discontinuous move in collective attention + capital toward an outcome, measurable in prediction markets (Polymarket / Kalshi / Manifold / Metaculus / PredictIt) and sector-rotation flows. Per AMENDMENT 47 §MCA-2, this IS the B_leak = consciousness measurement instrument where it covers an outcome. Direction contextual depending on which outcome the pull targets.
leverage 50
Prediction markets reprice when collective pull on an outcome moves.
02
Institutional trust decaySignal-class: measurable datum tracking collective trust in institutions — Pew/Gallup polling on Congress/Supreme-Court/media/science/business, approval ratings, cross-party cooperation rate, voter-turnout participation vs grievance, protest-event counts. Direction typically Timeline-B on democratic-haywire cycle.
leverage 55
Falling institutional trust accelerates the destabilization timeline.
03
Institutional defenderActor-class whose role is preservation of existing institutional architecture against erosion pressure. Courts, independent agencies, free-press leadership, academic institutions, professional-standard bodies. Direction typically Timeline-A on democratic-haywire cycle.
leverage 60
Defenders of courts, press, elections keep institutional timelines on track.

  • Fresh readings from Global Carbon Budget 2024 (2024-11-13) — Friedlingstein et al. — current global emissions trajectory pointing toward Peak Too Slow
Signals toward B
  • China coal-and-renewables trajectory holding against the shift toward Faster Decline
  • US fossil-fuel policy readings confirming the Faster Decline direction
  • Emerging-market electrification pace trajectory bending toward Faster Decline
  • Fresh readings from UNEP Emissions Gap Report 2024 (2024-10-24) — Policy-emissions gap documented pointing toward Faster Decline
