Mitigation of greenhouse gas emissions in livestock production: a review of technical options for non-CO2 emissions

This report presents a unique and exhaustive review of current knowledge on mitigation practices for greenhouse gas emissions in the livestock sector. It focuses specifically on non-CO2 emissions from enteric fermentation and manure management.

The report concludes that overall, improving forage quality and the overall efficiency of dietary nutrient use is an effective way of decreasing GHG emissions per unit of animal product. Some mitigation practices are synergistic and are expected to decrease both enteric and manure GHG emissions (for example, improved animal health and animal productivity). Optimizing animal productivity can be a very successful strategy for mitigating GHG emissions from the livestock sector in both developed and developing countries.
