The document discusses the impact of the dairy industry on air quality and climate change. It provides background on air quality legislation and regulations in the US, noting that agriculture was initially excluded. It identifies key pollutants of concern from dairy operations and their effects. Priorities for emission control are outlined based on the scale of pollution effects. Research needs are identified to better understand emissions and management practices to reduce them.
