Overview
The national picture
The Big PictureHow much greenhouse gas do America's largest polluters release, and is it going down? About 7,500 large facilities report to the U.S. EPA every year.Trends Over TimeHow have emissions changed since 2011? Lines show each year's total reported emissions in metric tons of CO2-equivalent.Emissions MapWhere are the emissions happening? Each circle is a facility; bigger circles mean more greenhouse gas.
Places & owners
States, companies, sites
Where Emissions HappenWhere do the emissions happen? States, counties and cities ranked by reported emissions for the selected year.Who Owns the Emissions?Which companies own the facilities that emit the most? Each facility reports its parent companies and their ownership percentages.Top EmittersThe 50 largest emitters for the selected year, state and industry, with each one's trend since 2011. Click a facility name to open its profile.Facility ProfileA profile of one facility: where it is, how its emissions have changed, which gases it releases and which activities cause them. Type a facility name in the box to switch.
Pollution & industry
Gases and activities
Types of PollutionWhich greenhouse gases are released? Carbon dioxide (CO2) comes mostly from burning fossil fuels.Industries & ActivitiesWhat activities cause the emissions?Oil & Gas SystemsOil and natural gas systems: production basins, gathering pipelines, gas processing plants, long-distance transmission pipelines, and the local gas utilities that deliver to homes.
Electricity
Power plants and fuel
How America Makes ElectricityHow does America make its electricity? Every U.S.Power Plants & CoalAmerica's fossil-fuel power plants: how big they are, what they burn, and how many coal units have shut down. Plant size is nameplate capacity in megawatts (MW).Power Plant EmissionsHow do individual power plants compare? Each operating fossil-fuel plant's size (operating capacity in MW) next to its 2023 greenhouse gas emissions.Emissions per Megawatt-hourHow much greenhouse gas does each megawatt-hour of electricity cost?Fuel for Power PlantsWhat do power plants pay for fuel, and where does it come from?
Environment & fuels
Water, ash, supply
Power Plant Water UsePower plants affect more than the climate. Coal, gas and nuclear plants pull huge amounts of water from rivers, lakes and the sea to cool their steam.Coal Ash & ScrubbersWhat happens to coal ash? Burning coal leaves fly ash and bottom ash, and SO2 scrubbers produce gypsum and sludge.Fossil Fuels SuppliedFuel suppliers: refineries, importers and natural gas companies report how much carbon is in the fuel they sell.Carbon StorageCarbon dioxide put underground.
iWhat the data covers. EPA's Greenhouse Gas Reporting Program collects emissions from
about 7,500 large facilities and systems (roughly half of U.S. emissions; cars, homes and farms are not included). EIA Form 923
covers every power plant of 1 MW or more, including nuclear, wind, solar and hydro.
