Nvyra’s Electrical Generation Rating Methodology measures the true environmental cost of electricity by converting verified pollution data into dollar-denominated social costs. Using plant-level emissions and a standardized monetization framework, we quantify how much environmental harm generators impose per dollar of revenue.
Applied consistently across fossil, nuclear, and renewable generation, our approach delivers an absolute, globally comparable measure of pollution intensity — cutting through greenwashing and making environmental impact financially visible.
Whether comparing utilities, assessing transition risk, or evaluating regulatory exposure, our ratings provide clear, comparable, and decision-ready insights.

Nvyra’s electrical ratings start with real, verified pollution data — not pledges or estimates. We measure the pollutants produced directly by electricity generation, using plant-level and operator-attributed emissions wherever available.
Our methodology focuses on the key pollutants from power production: CO₂, CH₄, N₂O, SO₂, NOₓ, mercury, and SF₆. Each pollutant is assigned a monetized social cost that reflects its real-world harm to health, climate, and ecosystems.
By converting emissions into dollar-denominated impacts, we make environmental damage financially visible and directly comparable.
Electricity generators vary widely in fuel mix, scale, and operating structure. To ensure fair comparison, Nvyra normalizes total environmental cost by adjusted operating revenue, measuring pollution intensity rather than absolute emissions.
This allows consistent comparison across utilities, independent power producers, cooperatives, and state-owned generators.
Each generator receives:
• Point-in-Time (PIT) Rating: current pollution cost per $1M of revenue
• Forward Rating: projected environmental cost intensity over five years
• Summary Opinion: a directional, risk-aware view of environmental trajectory
We convert emissions into dollar-denominated social costs using authoritative benchmarks — revealing the true environmental cost of electricity per dollar of output.
Pollution is standardized by output and adjusted revenue, enabling apples-to-apples comparison across utilities, IPPs, cooperatives, and state-owned generators.
We project future environmental exposure over five years, incorporating emissions trends, regulatory pathways, and operational volatility.
