Include livestock methane in carbon budgets and climate targets; mandatory livestock methane reporting

Livestock methane emissions account for over 36% of anthropogenic methane emissions globally, making them a significant driver of near-term warming and a critical gap in current carbon budgets and climate targets [Rockström et al., 2023]. Including these emissions in carbon budgets and mandating their reporting would address the underrepresentation of livestock in climate policy, enabling more accurate tracking and mitigation of a major source of greenhouse gases, which is essential for achieving global climate goals and transforming food systems toward sustainability [Scarborough et al., 2023].
