According to a study that involved researchers from the U. S. Department of Energy (DOE)’s Argonne National Laboratory, innovation in agriculture practices and technologies can cut down greenhouse gas (GHG) emissions from grain production by as much as 70% within the next 15 years.

The study, published in the Proceedings of the National Academy of Sciences of the United States, pointed out a combination of readily adaptable technological breakthroughs that can considerably reduce GHG emissions and be accommodated within the established grain markets and existing production systems.
According to the article titled, “Novel technologies for emission reduction complement conservation agriculture to achieve negative emissions from row-crop production,” reduction in GHG emissions could be achieved through crop and microbial genetics, digital agriculture and electrification.
Implementing the new technologies could drive the decarbonization of agriculture and, at the same time, support farm resilience and maintain productivity and profitability.
Technologies are classified into three parts: optimize, replace and redesign. The researchers employed the GREET® model from Argonne National Laboratory to replicate the adoption of the new technologies for the reduction of GHG emissions from grain production.
Argonne designed GREET, which stands for Greenhouse gases, Regulated Emissions, and Energy use in Technologies Model — a unique lifecycle analytical tool currently used globally by industry, government and the science community.
The study provides insights for developing new potential methods for agricultural decarbonization and recommends entry points with private and public investment based on a timeframe of predicted returns on investment in novel technologies.
Our study emphasizes the importance of a two-pronged approach ― reducing farming emissions and maximizing soil carbon storage ― to addressing the climate crisis through agriculture. Practices that enhance soil carbon storage continue to gain momentum. Complementing this approach by developing and broadly applying emission reduction technologies, including seed genetics, is critical to achieving net negative production.
