All 10 of the largest U.S. meat and dairy companies have lobbied against environmental and climate policies, resisting climate regulations, including rules on greenhouse gases and emissions reporting. This is according to a study by New York University, which examined the political influence of the 10 largest meat and dairy companies in the United States.
