405.4M MT CO₂e

Texas reports 405.4M MT CO₂e from 1,176 EPA GHGRP facilities and 322 parent companies (#1 of 54 U.S. states by aggregated facility CO₂e), led by Vistra at 45.1M MT (~11% of the state total).

  • #1 of 54 states
  • Vistra 11.1% of state
  • 15.8% of U.S. GHGRP total
  • Avg 345K MT per facility · May 2026

Dispersed in-state reporter mix

Vistra is the largest single reporter at 11.1% of Texas CO₂e (45.1M MT), but the top three still account for only 21.8% across 322 parent companies. Shares use EPA GHGRP facilities sited in TX only, not each parent's company-wide total.

  • Texas is 15.8% of the 2.57B MT U.S. GHGRP facility rollup across 54 jurisdictions.
  • Leading EPA sector by CO₂e: Power Plants at 49.3% (200.1M MT across 151 facilities) - orthogonal to the facility-count sector mix below.
  • Leads Louisiana by 256.6M MT on the same state ranking.
