How Air Pollution Is Measured (cont.)

• Broken down into categories (cont.)

• • HAP — “hazardous air pollutants” — generic “other” category
  • CO2e — CO2 (carbon dioxide) Equivalent (i.e. GHG, Greenhouse Gasses)
  • • Politically leveraged
    • • Cause planet-wide environmental harm (global warming, ocean acidification)
      • Methane is a potent greenhouse gas: 100x CO2 over 20 years, 25x over 100 years
      • Too much methane emissions and shale gas is worse than coal for climate change
    • Methane is their product: whatever is emitted is money thrown away
