How this calculator works

Payback Years = Embodied Carbon / Annual Emissions Saved

How to use

  1. Enter baseline values from recent real data.
  2. Run baseline scenario and note primary output.
  3. Stress test assumptions and compare delta.
  4. Use results to set an actionable plan.

Interpretation

Focus on direction and sensitivity, not just one absolute number. If small input changes swing outputs heavily, build a wider execution margin.

Common mistakes

  • Using stale inputs.
  • Ignoring downside cases.
  • Acting on one run without comparison.

FAQ

Is this exact forecasting? No, it is a structured planning model. Best practice? Re-run monthly with fresh inputs.
