Tools & capabilities
Epa Emissions tools 5
ghg_facility_emissionsThe biggest greenhouse-gas-emitting facilities in a US state (EPA GHGRP), ranked by total CO2-equivalent emissions. Returns each facility's name, location, industry sector(s), and total metric tons CO2e. State-scoped (pass a state). Data lags ~1.5 years — latest full year is auto-selected (currently 2023) unless a `year` is given.ghg_emissions_by_sectorTotal greenhouse-gas emissions by INDUSTRY SECTOR within a US state (EPA GHGRP) — answers 'which sectors emit the most in <state>'. Sectors: Power Plants, Refineries, Chemicals, Metals, Minerals, Pulp and Paper, Petroleum and Natural Gas Systems, Waste, etc. Returns each sector's total metric tons CO2e and facility count, ranked. State-scoped (pass a state); data lags ~1.5y so the latest full year (~2023) is auto-selected unless `year` is given.tri_facility_releasesSearch EPA TRI toxic chemical release facilities by state, and optionally by COUNTY — "what toxic releases are reported in Harris County, Texas" is the shape these questions usually take. Returns facility location, county, type, and chemicals released with quantities in pounds.tri_chemical_releasesTrack toxic chemical releases by chemical name and state. Returns quantities released to air, water, and land broken down by year.tri_trendsAnalyze toxic release trends over time by state or chemical. Returns historical release data across years to identify patterns and changes.
