lookup_emission_factor

Look up EPA eGRID electricity emission factors for a US ZIP code.

Inferred read-only

lookup_by_coordinates

Look up emission factors by latitude/longitude.

Inferred read-only

lookup_batch

Look up emission factors for up to 100 ZIP codes in one call (split longer lists).

Inferred read-only

calculate_emissions

Calculate Scope 2 CO2e for a facility from its ZIP and kWh, using both GHG Protocol methods: location-based (eGRID subregion rate) and market-based (Green-e residual mix applied to kWh not covered by RECs, PPAs or green tariffs).

Inferred read-only

hourly_intensity

Get hourly grid carbon intensity (kg CO2e per kWh) for any US ZIP code, derived from EIA-930 hourly fuel-mix data.

Inferred read-only

plant_emissions

Get hourly unit-level emissions from EPA Clean Air Markets Division (CAMD) for a specific US power plant or state.

Inferred read-only

utility_tariff

Get the actual utility-specific electricity rate (not state average) for a US ZIP code or named utility.

Inferred read-only

electricity_rate

Get the latest monthly average retail electricity rate ($/kWh and cents/kWh) for any US ZIP code, broken out by sector (residential, commercial, industrial, etc.

Inferred read-only

compare_sites

Compare and rank 2-25 candidate US sites (ZIP codes) for a facility, data center or EV/flexible load on grid carbon and electricity cost in one call.

Inferred read-only

cleanest_hours

Find the cleanest (lowest grid carbon) contiguous window of N hours in the day to run a flexible load (batch jobs, EV charging, pumping, HVAC pre-cooling) at a US ZIP code or balancing authority.

Inferred read-only

calculate_fuel_emissions

Calculate Scope 1 stationary-combustion emissions (CO2, CH4, N2O and CO2e) for fuels burned on site, using the GHG Emission Factors Hub 2026 (Cornerstone, successor to EPA's Hub; IPCC AR6 GWPs) by default, or EPA's 2025 edition (AR5) with edition=2025.

Inferred read-only
