U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) has supported the Systems Assessment Center of the Energy Systems Division at Argonne National Laboratory to examine carbon intensity (CI) variations of different farming practices to grow agricultural crops for biofuel production and further develop a transparent and easy-to-use tool to calculate feedstock-specific, farm-level CI of biofuel feedstock. The tool uses life cycle inventory (LCI) data of key farming inputs from the Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) fuel-cycle model. The system boundary of FD-CIC covers the cradle-to-farm-gate activities, including upstream emissions related to farming input manufacturing and feedstock production.

• Dynamic version: The dynamic version interacts with the GREET fuel cycle model by directly reading the LCI data of key farming inputs from the model. The dynamic version suits well when users want to change the default settings of the GREET model as related to farming inputs. The dynamic version is included in the GREET Excel release package.
• Standalone version: The standalone version suits well for users who are not familiar with the GREET model and contains the default LCI data for key farming inputs from the GREET model.
