Methane leakage thresholds for net climate benefits of wastewater biogas recovery

Nature Sustainability, Published online: 27 April 2026; doi:10.1038/s41893-026-01818-7 Biogas recovery enables renewable energy production alongside waste treatment, but the climate benefits are compromised by methane leakage. Here the authors systematically assessed how to manage methane leakage for sustaining net climate benefits of wastewater biogas recovery.
