This clean energy project avoids as much CO₂e as:

Environmental, Human Health & Economic Impacts

Screening tool. Results are reduced-form, scenario-conditional estimates intended for planning, education, and communication. They are not project-finance evaluations and should not be used in regulatory filings without methodological review.

Projection scheme matters. Lifetime avoided emissions can vary by more than an order of magnitude across the available schemes for the same physical project. Try several before drawing conclusions.

what it is:

An integrated avoided‑emissions and impact calculator for electricity‑sector projects. It translates a user‑defined intervention (generation, demand reduction, or fossil reduction) into annual generation or load changes, avoided CO₂/CO₂e and criteria‑pollutant emissions, and downstream climate, health, and sea‑level impacts over the project life.

The tool links five main components:

- Electricity system baselines and marginal emissions (EPA AVERT, EPA eGRID, NREL Cambium)

- Policy and scenario pathways (simple projection schemes, regional goals, and Cambium scenarios)

- Demographic and climate futures (SSPs, UN WPP / IIASA WiC population)

- Reduced‑form air‑quality and health damages (EPA COBRA, COBRA‑style factors)

- Climate‑mortality and physical‑climate responses (DICE‑EMR‑style MCC, temperature, ocean, and sea‑level modules).
