\n Argonne researchers quantify how to reduce emissions by farms changing their practices and adopting novel technologies.<\/p>\n
\n <\/section>\n

Currently, the agriculture sector contributes significantly to the greenhouse gas (GHG) emissions in the United States, accounting for nine percent of the nation’s overall\u00a0GHG\u00a0emissions.\u00a0 The practices that grain farmers use to produce their crops\u2014managing fertility, tillage practice and crop rotations\u2014influence the overall carbon footprint of U.S. agriculture.\u00a0 By using sustainable practices, farmers could substantially reduce their carbon footprint and become a vital partner to the biofuel industry in its efforts to produce the lowest carbon fuels possible.<\/p>\n

“This work is unique since we provide a complete quantification of carbon intensity (CI) for the cradle-to-farm-gate activities by conducting scenario-based analysis for selected farming practices that uses regionalized life cycle inventory data and a spatially explicit soil organic carbon modeling tool.”\u2014Xinyu Liu, postdoctoral app<\/a>ointee
\nA recent study by researchers in the Energy Systems division at the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory quantified how much farms might reduce emissions by changing their practices and adopting novel technologies. Xinyu Liu, a postdoctoral appointee, wrote about the pivotal research in\u00a0Environmental Research Letters<\/i>, published on July\u00a020. She collaborated with Hoyoung Kwon, principal environmental scientist, and Michael Wang, manager of systems assessments, all of Argonne; and Daniel Northrup, a former contractor to\u00a0DOE’s Advanced Research Projects Agency-Energy (ARPA-E), now with Benson Hill, a crop improvement company in St. Louis.
\n“This work is unique since we have quantified how the carbon intensity (CI) of corn feedstock would change with a wide range of farming practices and different farming regions. Besides the\u00a0GHG\u00a0emissions from manufacturing and applying farming inputs, we have also considered the impacts from soil organic carbon,” said Liu.
\nThe research focused on the corn belt of Illinois, Indiana, Iowa, Minnesota, Nebraska, Ohio, Michigan, South Dakota and Wisconsin and showed how different farming practices affect feedstock\u00a0CI. Sustainable farming professionals could implement lower\u00a0CI\u00a0practices, such as adopting conservation tillage, reducing nitrogen fertilizer use, and implementing cover crops, to reduce their carbon footprint, which could improve farm efficiency and help the environment.\u00a0
\nThe Argonne team’s research has historically focused on the\u00a0CI\u00a0of biofuels, which is determined via the life-cycle analysis technique to account for the energy\/material uses and emissions as feedstock is produced and converted to fuel. The technique is used by California Air Resources Board’s Low Carbon Fuel Standard (LCFS) program to calculate biofuel\u00a0CI. Farms that reduce biofuel\u00a0CI\u00a0can generate\u00a0LCFS\u00a0credit, which has monetary value for biofuel producers and potentially for farmers supplying the lower carbon feedstocks. Biofuel producers can improve their overall\u00a0CI\u00a0score by rewarding feedstocks with lower\u00a0CI, thereby further reducing the total\u00a0CI\u00a0of biofuels.
\nCurrently,\u00a0LCFS\u00a0allows applications from individual biofuel conversion facilities, which resulted in significant investment and innovation in production processes to reduce\u00a0CI. However, the board scores the\u00a0CI\u00a0for feedstocks based on a national average, regardless of the significant field-level variations in\u00a0CI\u00a0based on production practice. The Argonne work determines the source of the variation and suggests that a change in farming practice would lead to major emission reductions if implemented broadly.
\n“We conducted scenario-based\u00a0CI\u00a0analysis of corn ethanol, coupled with regionalized inventory data, for various farming practices to manage corn fields and identified key parameters affecting cradle-to-farm-gate\u00a0GHG\u00a0emissions,” said Liu.\u00a0“The results demonstrate large spatial variations in\u00a0CI\u00a0for corn, and eventually for ethanol, due to farm input uses and land management practices.”<\/p>\n
