S4E45: "How Dairy Innovations Are Redefining Methane Reduction with Paul Sousa"

The Skim:

In this episode of the "Seen and Herd" podcast, Paul Sousa, the Director of Regulatory Affairs at Western United Dairies, discusses the latest regarding methane emissions particularly related to livestock and the agriculture industry, focusing on California. 

Key topics include:

Paul Sousa highlights the importance of reducing methane emissions due to their potent impact on climate change despite their shorter lifespan compared to carbon dioxide.

Paul talks about the significance of methane emissions from livestock, particularly dairy cows, and the ways in which these emissions occur, such as through manure and enteric emissions from rumen fermentation. Paul discusses the progress made in California in reducing methane emissions from dairy farms through various programs like the Alternative Manure Management Program (AMP) and DairyPlus.

He explains the funding available for climate-smart agriculture practices, including digester projects, manure separators, composting, and other methods aimed at reducing methane emissions and improving water quality on dairy farms. Paul emphasizes the importance of planning early for these applications to ensure a smoother process and better decision-making when selecting equipment and projects.

Additionally, there's a brief mention of a proposal to revise the Low Carbon Fuel Standard (LCFS) that might exclude dairy digesters from participation due to environmental justice pressure, potentially hindering the state's progress in reducing greenhouse gas emissions.
