ESG Score Sanity Checker
Verify ESG scores against underlying metrics and identify inconsistencies. Enter values for instant results with step-by-step formulas.
Formula
Sanity Score = Cross-reference(Pillar Scores, Underlying Metrics, Industry Benchmarks)
Compares reported ESG pillar scores against supporting metrics (carbon, diversity, board independence) and industry benchmarks to identify inconsistencies suggesting inflated or deflated ratings.
Worked Examples
Example 1: Tech Company - Consistent
Problem:E: 75, S: 70, G: 80. Carbon: 80 tCO2e/$M, 50% renewable, 45% diversity, 75% board independence.
Solution:Sanity Checks:\n✓ E score 75 with low carbon (80) - consistent\n✓ E score with 50% renewable - supports high score\n✓ S score 70 with 45% diversity - reasonable\n✓ G score 80 with 75% independence - consistent\n\nBenchmark (Tech): E:70, S:65, G:70\nDifferences: E+5, S+5, G+10\n\nAll scores slightly above benchmark but supported by metrics.\n\nReliability: High\nNo major inconsistencies detected.
Result:Overall: 75 | High Reliability | Metrics support reported scores
Example 2: Energy Company - Red Flags
Problem:E: 70, S: 65, G: 60. Carbon: 450 tCO2e/$M, 10% renewable, 30% diversity, 40% board independence.
Solution:Sanity Checks:\n❌ E score 70 but carbon 450 (industry: 500) - score seems inflated for actual emissions\n❌ E score high with only 10% renewable\n⚠️ G score 60 with 40% board independence - weak governance\n\nBenchmark (Energy): E:45, S:55, G:65\nDifferences: E+25 (suspicious), S+10, G-5\n\nE score is 25 points above energy benchmark despite high absolute emissions.\n\nReliability: Low\nMajor inconsistencies in Environmental scoring.
Result:Overall: 65 | Low Reliability | E score likely inflated - investigate
Example 3: Finance - Mixed Signals
Problem:E: 65, S: 55, G: 85. Carbon: 40 tCO2e/$M, 45% renewable, 25% diversity, 80% board independence.
Solution:Sanity Checks:\n✓ E score 65 with low carbon and good renewable - appropriate\n⚠️ S score 55 with only 25% diversity - might be low\n✓ G score 85 with 80% independence - well supported\n\nBenchmark (Finance): E:60, S:60, G:75\nDifferences: E+5, S-5, G+10\n\nS score below benchmark, other pillars above.\nDiversity ratio low for stated S score.\n\nReliability: Moderate\nSocial metrics warrant investigation.
Result:Overall: 68 | Moderate Reliability | Social pillar may be overstated
Frequently Asked Questions
What is an ESG score?
ESG scores rate companies on Environmental (emissions, resource use), Social (labor practices, diversity), and Governance (board structure, ethics) factors. Scores typically range 0-100, with higher being better. Major providers: MSCI, Sustainalytics, S&P Global.
Why do ESG scores differ between providers?
Different methodologies: varying weights (E vs S vs G), different metrics, proprietary algorithms, and data sources. MSCI and Sustainalytics ratings for the same company can differ by 2+ letter grades. Always know the methodology.
What makes an ESG score unreliable?
Red flags: high scores with poor underlying metrics, significant provider disagreement, self-reported data without verification, scores improving despite unchanged practices, industry-leading scores in polluting sectors.
How do I verify ESG data?
Cross-reference: check multiple rating providers, review underlying data (carbon reports, diversity disclosures), look for third-party verification, compare to industry peers, and check for controversies/violations.
