What is FD-CIC Tool?
U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) has supported the Systems Assessment
Center of the Energy Systems and Infrastructure Analysis 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 R&D 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.

Major Expansions and Updates in 2023:
- Expanded FD-CIC for life cycle analysis of multi-year crop production in common crop rotations, including corn-soybean, continuous corn, and corn-corn-soybean rotations and the associated soil organic carbon (SOC) changes.
- Revised key assumptions and calculation method to estimate GHG emissions, including N2O emissions of Right source, Right rate, Right time, and Right place (4R) practices.
- Revised the default fertilizer and pesticide usage data for corn and soybeans, which are based on the NASS database and cover the years 2021 for corn and 2020 for soybeans.
- Updated the Brazilian sugarcane production parameters based on the data collected from 67 sugarcane mills in the 2019/2020 period, through Brazilian government’s National Biofuels Policy.
- Redesigned the input and result worksheets for single-year domestic crop farming.

Two versions of FD-CIC tool
- Dynamic version: The dynamic version interacts with the R&D 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 R&D GREET model as related
to farming inputs. The dynamic version is included in the R&D GREET Excel release package.
- Standalone version: The standalone version suits well for users who are not familiar with the R&D GREET model and contains the
default LCI data for key farming inputs from the R&D GREET model.
