2023 nearly all-CO₂ parent book

This parent's 2023 facility book is almost entirely CO₂ (99.7% of 4.5M MT CO₂e). CH₄ and N₂O together are only 0.3%, a CO₂-shaped GHGRP profile, not a methane story. Component shares sum this parent's facility CO₂ / CH₄ / N₂O rows for that year, not a corporate Scope 1-3 inventory.

What to do with this

Using Hawaiian Electric Industries's emissions profile

  • Hawaiian Electric Industries runs high-intensity per facility (409K MT CO₂e/site); see how it stacks up against the rest of the Power Plants sector on the Power Plants industry page.
  • It ranks #117 of 2,289 reporting parents nationwide, compare it directly against specific peers on the compare tool.
  • Not sure how to read a total-CO₂e figure or a per-facility intensity number, the how-to-read guide walks through what each field means and what it doesn't.
