Climate Policy Fragments, Capital Flows Face Global Risk

C-MACC Weekly Sustainability and Energy Transition Report

Climate Policy Fragments, Capital Flows Face Global Risk

  • 1st Topic of the Week: As US federal climate rules recede, will fragmented state policies form a viable national framework, or deepen structural uncertainty that reshapes investment, compliance, and competitiveness?
  • 2nd Topic of the Week: Hydrogen capital pivots from speculative megaprojects to regulated niches, as structural cost gaps persist and only compliance-driven mandates now dictate scale, returns, and ultimately survival.
  • Otherwise – Global energy transition markets are fragmenting as politics, policy, and cost pressures redirect capital, reshaping power, materials, emissions compliance, clean fuels, ESG investing, and competitiveness.

Exhibit 1: 2009-2025 EPA climate authority timeline; proposed rollbacks could cut US GHG oversight by ~80%.
