Steady on, you probably should read the study itself before you make false claims. It doesn’t really take science literacy, just literacy and a desire to resist confirmation bias not to imagine that the ammonia fertilizer industry at 0.2 of methane emissions is the single cause of methan emissions and cancels out that produced by cows:
Comparing against U.S. EPA’s 2016 GHG inventory (United States Environmental Protection Agency, 2017b), we find that the estimated methane emissions (nominal case) from the ammonia fertilizer industry are more than three times higher than the reported methane emissions from industrial processes and product use (i.e. around 8 Gg CH4/yr, mainly from petrochemical production). As one of a major end-user of natural gas systems, it represents about 0.2% of methane emissions from the U.S. oil and gas supply chain (i.e. 13 ± 2 Tg/yr) under the nominal case estimation (Alvarez et al., 2018). Relative to other major sectors of methane emissions in the U.S. (United States Environmental Protection Agency, 2017b), such as enteric fermentation (6.8 Tg CH4/yr) and landfills (4.3 Tg CH4/yr), methane emissions from the ammonia fertilizer industry are quite low. Given the small number of ammonia fertilizer plants, however, the ammonia fertilizer industry has great potential for mitigation.
