We’re not even a third of the way through 2019, but we already have a frontrunner for a political fact-checker’s annual “Lie of the Year” award: the trendy yet incorrect political/media narrative that if we all just cut back on eating delicious real beef hamburgers, we’re going to stop or significantly slow climate change.

You’ve heard the drumbeat all year. U.S. Rep. Alexandria Ocasio-Cortez unveiled her so-called “Green New Deal” in January, lamenting that we probably can’t “get rid of all the farting cows” in just 10 years. Vegan U.S. Sen. Cory Booker claimed our planet “can’t sustain billions of people consuming industrially produced animal agriculture.”

And then (appropriately) on April Fools’ Day, Burger King announced it would start selling beefless “Impossible Whoppers” – and the big-city media fell right into line extolling the supposed Earth-saving opportunity represented by the heme- and soy-based product.

On April 9, Wall Street Journal columnist Walter Russell Mead praised the alleged environmental benefits of fake meat, while complaining that “9 percent of U.S. greenhouse-gas emissions come from agriculture, and almost one-third of that comes from cattle-based methane.”

Not to be outdone, the Washington Post on April 16 ran not one, but two, long, nearly identical articles about the Impossible Whopper – combining for a “whopping” 2,158 words in that day’s print edition.

While one Post article lauded the product’s supposedly “environmentally friendly message” and “environmental appeal,” the second went a step further, claiming that eating less beef “could help reduce the many environmental impacts that raising cattle has on our vulnerable planet” and possibly even “save (planet) Earth.”

Predictably, none of these politicians or journalists included any sourced data to support their assumptions, so I’ll do that here.

Here are the facts. According to the EPA, direct emissions from beef cattle in the United States account for only 2 percent of our nation’s total greenhouse gas emissions. Moreover, USDA recently reported that U.S. beef cattle production is “not a significant contributor to long-term global warming.”

Compare U.S. cattle’s 2 percent to the transportation and electricity sectors, which account for a combined 55 percent of our nation’s emissions, with another 41 percent coming from other sources.

The truth is, beef production in the United States has become much more efficient and environmentally sustainable over the past few decades. Compared to 1977, today’s American beef farmers and ranchers produce the same amount of beef with 33 percent fewer cattle. Improved efficiency and animal well-being mean a 16 percent lower carbon footprint and fewer natural resources used for every pound of beef produced.

And contrary to Sen. Booker’s vegan utopia, research shows that if every American went vegan, U.S. greenhouse gas emissions would only drop 2.6 percent. At the same time, our national diet would provide insufficient nutrients to feed the U.S. population and result in increased use of synthetic fertilizer, as well as increased soil erosion.

If all these politicians and elite journalists want to replace delicious and nutritious American-produced beef in their diets with heme and soy, we wish them the best (along with our sympathies). But to claim that doing so will have any significant impact on global climate is ultimately the real whopper in this debate.
