Public Largely Unaware of Meat And Dairy's Contribution to Climate Change

Yale Environment 360 - Wed, 12/03/2014 - 11:09

The general public has a major lack of understanding of how eating meat and dairy contributes to climate change,

Perceived vs. actual carbon emissions according to a survey of Europe, the Americas, Asia, and Africa by the market research organization Ipsos MORI. Although meat and dairy production accounts for roughly 15 percent of total global carbon emissions — equal to exhaust emissions from the international transportation sector — less than 30 percent of survey respondents identified meat and dairy production as a major contributor to climate change. More than twice as many — 64 percent — said transportation was a major contributor. Closing the awareness gap is essential for changing meat and dairy consumption patterns, researchers said, especially in developed nations such as the U.S. Although much of the projected increase in meat and dairy consumption will likely happen in emerging economies, respondents in Brazil, India, and China demonstrated greater consideration of climate change in their food choices and above-average willingness to modify their consumption — an encouraging sign, researchers said.
