Measuring Carbon Avoidance Efficiency: Six Orders of Magnitude in Climate Equities (2026)
Pazos, J. Under review at Sustainability (MDPI).
Earlier preprint: SSRN, DOI: 10.2139/ssrn.4623238

Introduces the Climate Efficiency Ratio (CER) — market capitalization per tonne of lifetime CO₂e avoided — computed via 34 sector-specific physics proxy models and applied to 187 publicly traded firms spanning 51 Project Drawdown solutions. CER spans six orders of magnitude across the universe; tier classifications persist at 83.5–90.2% over 12 months.
