Greenhouse gas statistics from the live GHGRP extract

Key findings on the 2023 reporting-year census versus the leftover-year warehouse, parent labels versus facility sectors, and CO₂e versus methane. Registry counts only, not climate or investment advice.

2,268 EPA GHGRP parents reported 2.38 billion MT CO₂e in 2023; Vistra leads at 86.3 million MT (3.6%), Power Plants are 60.3% of that year, and Texas is 15.9%.

  • Power Plants 60.3% of 2023 vs industries-table leftover-year rollup
  • Waste Management leads methane and is #36 on CO₂e

Key findings

Standalone, citable statements from this extract. Free to reuse with attribution to PlainCarbon and EPA GHGRP (CC BY 4.0 for this compilation; cite the page).

  • 2,268 of 2,289 parent companies reported in 2023 (21 last appear in an earlier year). The warehouse holds 8,713 facilities; 6,455 reported in 2023. Do not treat the warehouse counts as the 2023 census.
  • 2.38 billion MT CO₂e in 2023 (yearly_totals = SUM of facility emissions for that year). That is -25.7% vs 2011 (3,207.6 million MT, 0.74×). More parents reported (2,268 vs the 2011 rollup) while the CO₂e total fell.
  • 86.3 million MT is Vistra's 2023 total (#1 of 2,268, 3.6% of the year). The top 10 parents hold 21.8% (520.4 million MT).
  • 99.5% of The Southern's 2023 CO₂e sits in Power Plants (26 of 38 facilities) even though the parent label is Natural Gas and Natural Gas Liquids Suppliers. The company.industry column is a primary-sector tag, not the facility mix.
  • 60.3% of 2023 CO₂e is Power Plants (1437.3 million MT across 1,291 facilities). The industries table latest-year rollup is 1550.5 million MT / 1,732 facilities and includes leftover years; do not cite that as the 2023 share.
  • 15.9% of 2023 CO₂e was reported from Texas (379.8 million MT, 851 facilities, 2.63× Louisiana). That is the 2023 emissions join, not the states-table latest-year total, which still carries leftover-year facilities. 54 jurisdictions are in the register (50 states plus DC, PR, GU, VI).
  • #36 is Waste Management's 2023 CO₂e ordinal while it leads methane at 11.5 million MT CO₂e. Vistra leads CO₂e and reports 0.1 million MT methane. The methane ladder is not the CO₂e ladder.
  • 25.4% of warehouse facilities (2,214 of 8,713) have no parent company_id. None of the 2023 reporters are unattributed; those rows are leftover-year facilities that inflate the warehouse and not the 2023 yearly total.

Every figure on PlainCarbon is rendered directly from EPA Greenhouse Gas Reporting Program (GHGRP) data, no number is typed in by an editor. Key findings use yearly_totals and SUM(emissions) for 2023; leftover-year warehouse counts are labeled as such and are not mixed into those shares.
