Enteric Methane Emission Reduction Programs

Livestock Enteric Methane Emission Reduction Research Program (LEMER-RP)

The Livestock Enteric Methane Emission Reduction Research Program (LEMER-RP) is a new program under CDFA’s Office of Environmental Farming and Innovation (OEFI). The Budget Act of 2022 (AB 179, Section 194) appropriated a total of $10 million payable from the Greenhouse Gas Reduction Funds (GGRF) to the CDFA to award a total of $9.5 million in competitive grant(s) to fund demonstration trials evaluating additives and dietary modifications that have the potential to reduce enteric methane emissions in the dairy and livestock sectors. These research projects will help address key barriers to achieving California’s climate goals, which include the reduction of methane emissions to 40% below 2013 levels by 2030 as codified in SB 1383 (Lara, 2016) as well as efforts to continue advancing climate-smart agriculture.

The funding allocated will be directed towards the dairy and livestock sectors for demonstration projects to:

  1. Supplement feed with additives or ingredients, that have scientifically demonstrated efficacy in reducing methane emissions, and
  2. Research dietary modifications that are intended to reduce methane emissions from livestock
