Emissions Capture Rate at 71% target emissions capture rate: a worked example

Suppose target emissions capture rate falls to 71%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate emissions capture rate from captured contaminant mass, generated contaminant mass, and target capture efficiency.

The inputs for this scenario

  • Captured contaminant mass: 970 lb (held at the documented default)
  • Generated contaminant mass: 1,000 lb (held at the documented default)
  • Target emissions capture rate: 71 % (the input this scenario stresses; the baseline uses 98)

Working through the calculation

  • The calculation starts from the formula this tool documents: Emissions capture rate = captured contaminant mass ÷ generated contaminant mass × 100.
  • Emissions capture rate works out to 97 % at these inputs, and this is the headline figure for the scenario.
  • Emissions capture gap to target works out to -26 points at these inputs.
  • Captured contaminant mass works out to 970 count at these inputs.
  • Generated contaminant mass works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target emissions capture rate sits at 98% and the headline result is 97 %, this scenario lands almost exactly on the baseline at 97 %.
  • It computes captured contaminant mass as a percentage of generated contaminant mass and compares it against your target capture rate. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Emissions capture rate: 97 % (headline result)
  • Emissions capture gap to target: -26 points
  • Captured contaminant mass: 970 count
  • Generated contaminant mass: 1,000 count

Run it with your numbers
