Project Ballast — Pollutant Mentions by Speaker

v2 · MGW.reference.ballast-pollutant-chart.071926.v2 · re-derived from the corrected 283-atomic ledger (mrx_bethune) 7/19/26 · supersedes the 07-15 v1 transcript-grep · 10 speakers named ≥1 pollutant

So what

NOx, SO2, PM, VOC, ozone and GHG tracked separately — most speakers name only particulate matter even when arguing the whole mix.

Why

Treating them as one “air quality” bucket is a credibility risk if a citation is parsed closely; match the specificity of what was actually said.

The catch

This is derived from the atomic claim texts, not a fresh transcript grep — a speaker who named a pollutant in words the atomic didn't capture may be undercounted.

Provenance. Re-derived by scanning the 283 corrected atomic claim texts (mrx_bethune.gasplant_atomic_sentiments) for each pollutant term, attributed to the corrected speaker; read-only 2026-07-19. This is a lower bound vs. a full transcript grep. Supersedes MGW.reference.ballast-pollutant-chart.071526.v1.
