Summary
This systematic review, published in Nature Climate Change, synthesises global evidence on greenhouse gas mitigation potentials across the livestock sector, evaluating technical and management interventions across cattle, pig, poultry and other production systems. The authors, a consortium of climate and agricultural scientists, assess the scale, cost, and regional feasibility of emissions reductions, providing a comprehensive evidence base for climate policy in agriculture. The work suggests substantial but variable mitigation opportunities exist, with effectiveness dependent on production context, technology adoption, and systemic factors.
UK applicability
Findings are relevant to UK livestock policy and farm management, particularly for dairy and beef systems which dominate UK livestock production. The review's assessment of feed efficiency, manure management, and breeding interventions directly informs UK agricultural climate commitments and farm carbon benchmarking schemes.
Key measures
Greenhouse gas emissions (CO₂-equivalents); mitigation potential (percentage or absolute reductions); cost-effectiveness of interventions; feasibility across production systems and regions
Outcomes reported
The study assessed mitigation potentials for greenhouse gas emissions across diverse livestock production systems and identified technical, management, and systemic interventions. It synthesised evidence on the scale and feasibility of emissions reductions across cattle, pig, poultry and other livestock sectors.
