Maps

GHGP Emitters Explorer

  This map visualizes every facility that reported direct greenhouse-gas emissions to EPA’s Greenhouse Gas Reporting Program

  (GHGRP) between 2011 and 2023. Circles are geolocated to facility coordinates; their size and color correspond to the

  selected year’s emissions (metric tons CO₂‑equivalent). It allows you to see where the nation’s highest-emitting plants and

  plants are, how individual sites have evolved, and which sectors dominate.

  How to Navigate

  - Click and drag to pan; use the scroll wheel or trackpad pinch to zoom.

  - The dropdown at top centers on a specific sector (power plants, chemicals, petroleum & natural gas systems, etc.) or

    leaves “All Sectors” visible.

  - Drag the year slider (2011 → 2023) to watch facilities shrink or grow. The legend reflects the same breakpoints as the

    circles (<50k → >5M metric tons).

  - Hover over a circle to preview name, sector, and emissions in the active year. Click to pin the full details panel (name,

    sector, city/state, year emissions, and peak 2011–2023 value).

  - To reset, set the dropdown back to “All Sectors” and slide to 2023.

  Reading the Map

  - Bright, large circles denote mega-emitters (multiple millions of metric tons), usually power plants or large

    petrochemical complexes.

  - Medium blues (200k–1M) often correspond to mid-sized industrial facilities, waste incinerators, or metal/mineral plants.

  - Light blue dots (<200k) are smaller but numerous; they highlight dense clusters of petroleum/gas systems in the Gulf

    Coast, along with municipal utilities, waste operations, etc.

  - In slider mode, watch how emissions shrink in some regions (e.g., Midwestern power fleet) while others stay flat (Gulf

    Coast petrochemical infrastructure) or grow (some Northeast facilities post‑2019).

  - If a facility is absent for an early year it either wasn’t reporting or emitted zero (hover text shows zeros when data

    isn’t available).

  Data Sources & Notes

  - EPA Greenhouse Gas Reporting Program (GHGRP) — Direct emitters dataset, 2011–2023 reporting years (CO₂e values from IPCC

    AR4 GWPs).

  - Each data point reflects the metric-ton value reported for that year; no modeling or averaging was applied.

  - The map only covers direct point emitters; other GHGRP categories (like suppliers, sequestration sites, onshore

    production) are not included here.

  Update Cadence & Feedback

  - The GHGRP is no longer updated annually as the US has decided not to believe in environmental data. This dataset was made to memorialize this data and show the importance of EPA data.
