Emissions-Reduction Calculator

The grant selections will be based, in part, on the tons of NOx projected to be reduced by the project. Applicants are not required to calculate the NOx emissions reductions, but are encouraged to do so in order to determine the expected cost per ton of NOx reduced. An electronic calculator is available to perform the calculations. Applicants should refer to the RFGA for more detailed information on the grant selection criteria and how to determine the NOx emissions reductions.

The calculators are in a Microsoft Excel format and will help you calculate your NOx emissions.

Step 1: Review the instructions in the RFGA.
Step 2: Download the appropriate calculator for your activity and save to your computer.
Step 3: Open the calculator.
Step 4: On summary worksheet click on blue hyperlink (note: this will be worded Worksheet OR-1. This link will take you to the first worksheet.
Step 5: Enter in the Activity Information.
Step 6: Enter in the Baseline Engine/Vehicle Information.
Step 7: Enter in the Reduced Emission Engine/Vehicle Information.
