Scope 1/2/3 emissions intensity API

Canonical GHG-Protocol carbon intensity: totalEmissions = scope1 + scope2 + scope3 (tCO2e), intensity = totalEmissions / revenueMillions (tCO2e per $M revenue); a 0-100 efficiency score maps 0 t/$M -> 100 and >=1000 t/$M -> 0 (lower intensity is better). Returns total emissions, intensity, efficiency score, rating, A-F grade, and a per-scope breakdown. Answers 'what's this firm's carbon intensity', 'sum scope 1/2/3 per $M revenue', 'score emissions efficiency'.
