Nah, it's still the cows. No citation of a livestock emissions figure is made by the author. They took an excellent study which didn't mention cows at all and repackaged it as clickbait for this company's blog...<p>29 gigagrams of methane per year from fertilizer plants, says the study. (The 28 gigagrams figure in the article is misquoted, Ctrl+F for "29 (±18) Gigagram per year" here <a href="https://www.elementascience.org/article/10.1525/elementa.358/" rel="nofollow">https://www.elementascience.org/article/10.1525/elementa.358...</a> )<p>6.2 teragrams of methane per year from livestock emissions, says this other study <a href="https://extension.psu.edu/livestock-methane-emissions-in-the-united-states" rel="nofollow">https://extension.psu.edu/livestock-methane-emissions-in-the...</a><p>Last I checked 6.2 teragrams is a lot more than 29 gigagrams.<p>On another note... I highly recommend looking at the original paper. Awesome visual of emissions data captured by Cornell University sensors onboard a Google Street View vehicle!

Did Cornell approach Google for this study or vice versa?
