The Emission Analysis step is optional, but is used to estimate the potential reductions of greenhouse gas emissions of the proposed project. There are five principal sections in this step:
- Settings - used to determine whether or not to perform the Emission Analysis, the type of analysis used, and global warming potential factors.
- Base case electricity system (Baseline) - calculates emission factors from the electricity production of the base case.
- Base case system GHG summary (Baseline) - summarizes the base case system emission factors and fuel consumption.
- Proposed case system GHG summary (Project) - summarizes emission factors and fuel consumption of the proposed case.
- GHG emission reduction summary - displays net annual greenhouse gas emission reduction and equates that to the number of cars and light trucks taken off the road in a given year.

The next step is the Financial Analysis.
