要旨

The livestock sector represents major challenges to safeguarding environmental integrity. This study comprehensively analyzes ten environmental footprints of the livestock sector from 1995 to 2022, with projections until 2030, and juxtaposes them with the planetary boundaries. We quantify greenhouse gas emissions, land use, water use, particulate matter formation, and biochemical flows associated with the livestock sector. Our findings indicate that the livestock sector alone poses a significant challenge to planetary boundaries and has the potential to threaten several of these boundaries by 2030. Scenario modeling shows that a “one-size-fits-all” strategy for all countries can be suboptimal. Conversely, a region-specific strategy that requires developed regions to align meat consumption with the Eat-Lancet diet while developing regions focus on improvement of production efficiency is optimal for reducing livestock's global environmental footprints. These findings highlight the need for targeted policy measures and regional strategies to effectively mitigate the environmental impacts of the livestock sector and ensure sustainable practices.
