CO₂ emissions over time

Carbon vs. mortality

Each scenario placed by its final-year CO₂ and its final-year deaths. Down-and-left is better on both; the spread shows where the two externalities pull apart.

  • MIDW · Carbon Only · $350/MT CO₂
  • MIDW · Central VSL · no carbon

The band is scientific uncertainty, not rounding. Each source's death rate is a central estimate with a much higher upper bound — coal's depends on how air-pollution exposure is modeled; hydro's high bound includes the 1975 Banqiao dam failure, its central figure excludes it. Reported deaths carry those ranges across the mix, so a mortality figure is a band skewed upward, never a single number. Pricing a death adds a second range (the VSL is itself low/central/high), so any priced-mortality cost inherits both.

What gets built (MW), as opposed to what runs (MWh above) — the two diverge where a source is built but dispatched less.
