Darrin Qualman, NFU Director of Climate Crisis Policy and Action, compiled the report from a number of studies that delved into individual sources such as methane from cattle.
Qualman said nitrogen fertilizer is the reason emissions are rising and although emissions from cattle are large, they are declining as cattle numbers decline.
He also notes that long ago buffalo populated the Prairies for millions of years.
Emissions from fossil fuels account for a third of the agriculture-related total; that includes both on-farm use and the manufacture of farm machinery and fertilizers.
