The global technical mitigation potential from agriculture (excluding fossil fuel offsets from biomass) by 2030, considering all gases, is estimated to be approximately 5500–6000CO2-eq. yr−1, with economic potentials of approximately 1500–1600, 2500–2700 and 4000–4300 Mt CO2- eq.−1.
Nutritional management for enteric methane abatement: A review
A variety of nutritional management strategies that reduce enteric methane (CH4) production are discussed. Strategies such as increasing the level of grain in the diet, inclusion of lipids and…

Rumen microbial community composition varies with diet and host, but a core microbiome is found across a wide geographical range
There were few strong co-occurrence patterns between microbes, suggesting that major metabolic interactions are non-selective rather than specific, and could make it possible to mitigate methane emissions by developing strategies that target the few dominant methanogens.

Feeding up to 2% of the dietary DM as quebracho tannin extract failed to reduce enteric methane emissions from growing cattle, although the protein-binding effect of the que bracho tANNin extract was evident.
Digestion, ruminal fermentation, ciliate protozoal populations, and milk production from dairy cows fed cinnamaldehyde, quebracho condensed tannin, or Yucca schidigera saponin extracts.
Results of this study show that under experimental conditions, supplementing dairy cow diets with CIN, QCT, or YSE had limited effects on digestion, ruminal fermentation characteristics, and protozoal populations, and the lack of effects observed suggests that these antimicrobials require administration at greater doses to favorably alter rumen microbial fermentation.
