2023 nearly all-CO₂ parent book
This parent's 2023 facility book is almost entirely CO₂ (99.7% of 836K 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.
