Minneapolis Mayor Jacob Frey signed a proclamation last week urging citizens to eat plant-based foods. The withdrawal of the United States from the Paris Agreement—a multinational coalition to reduce greenhouse-gas emissions to slow climate change by 2050—prompted the mayor to issue the document in an effort to promote environmentally friendly eating habits. “If each American affirmatively chose to eat plant-based food at just one meal per week,” the proclamation stated, “the carbon dioxide savings would be the same as taking more than half a million cars off US roads.” The mayor further urged citizens to “make an effort to eat plant-based food and choose plant-based products in furtherance of our environmental goals, and celebrate our ongoing commitment to exceed the standards put forth in the Paris Agreement by doing our part right here in Minneapolis.” A study published in March in scientific journal Environmental Research Letters found that individuals that consume beef are responsible for 46 percent of all US greenhouse-gas emissions.
