This report analyzes the proposed EMIT LESS Act of 2024, a bipartisan legislative initiative aimed at reducing methane emissions from the U.S. livestock sector, particularly emissions produced through enteric fermentation in cattle. Methane is a highly potent greenhouse gas—approximately 86 times more powerful than carbon dioxide over a 20-year period—and agriculture accounts for roughly 40% of anthropogenic methane emissions globally. The report evaluates technological and policy solutions to mitigate these emissions, including dietary interventions such as feed additives, genetic selection for low-methane livestock traits, microbiome modifications, and vaccine development targeting methane-producing microbes. Each intervention presents varying degrees of technological readiness, cost implications, and regulatory challenges.

To support the adoption and scaling of these mitigation strategies, the EMIT LESS Act proposes a federal research and implementation framework led by the U.S. Department of Agriculture (USDA). The legislation prioritizes voluntary participation by farmers while advancing research through the Agricultural Research Service and promoting on-farm adoption through education and technical support programs coordinated by the National Institute of Food and Agriculture. The report outlines a two-year implementation plan that includes establishing new program management structures, conducting research trials, and developing monitoring and reporting systems to evaluate methane reduction outcomes. With an estimated budget of $90 million over two years, the proposed program seeks to balance environmental sustainability with economic feasibility for farmers while strengthening collaboration among government agencies, academic institutions, industry stakeholders, and producers to accelerate climate-smart agricultural innovation.
