Substitutes Shist with fossil-fuel-only cumulative CO₂ · GCP
When active, Shist uses fossil-fuel-only scores (LULUCF excluded). Rankings update automatically.
Total weight: 100%
Adjusting weights recalculates all scores live. The "Δ Rank" column shows how each country's ranking changes relative to the published formula.
