This report, prepared in advance of the United Nations Conference of the Parties 21 (COP21) in Paris, reviews the scientific literature on the roles of reducing animal product consumption and wasted food in meeting climate change mitigation targets.

Key findings

  • If global trends in meat and dairy intake continue, global mean temperature rise will more than likely exceed 2° C, even with dramatic emissions reductions across non‐agricultural sectors.
  • Immediate and substantial reductions in wasted food and meat and dairy intake, particularly ruminant meat (e.g., beef and lamb), are imperative to mitigating catastrophic climate change.
  • The urgency of these interventions is not represented in negotiations for climate change mitigation.
