Analyzing program impact

Use the Marginal Abatement Cost Curve (MACC) to compare and prioritize programs based on cost and carbon abatement potential. The MACC curve represented here is designed to depict which programs abate the most carbon and how much they cost relative to one another.

1. Open the Program Analysis worksheet.
2. Review the MACC chart.

   The chart shows:

   • Left to right: increasing cost per kg CO₂ abated.
   • Bar width: total abatement per program.

   Programs on the left cost less per kilogram of CO₂ abated. Wider bars indicate higher total abatement.

3. Compare initiatives side by side to decide which programs to scale, refine, or deprioritize.
4. Set Program Status to Approved or Draft to simulate governance scenarios.
5. View the programs adjusted baseline scenario.

   Approved programs update the baseline in a new scenario that is called Baseline Programs Adjusted. This new scenario adjusts your business as usual emissions based on the programs and actions selected in the Program Setup worksheet. To see this change, navigate to the Scenario Analysis worksheet.
