<jats:title>Abstract</jats:title><jats:p>Nitrous oxide (N<jats:sub>2</jats:sub>O) is approximately 265 times more potent than carbon dioxide (CO<jats:sub>2</jats:sub>) in atmospheric warming. Degraded peatlands are important sources of N<jats:sub>2</jats:sub>O. The more a peat soil is degraded, the higher the N<jats:sub>2</jats:sub>O-N emissions from peat. In this study, soil bulk density was used as a proxy for peat degradation to predict N<jats:sub>2</jats:sub>O-N emissions. Here we report that the annual N<jats:sub>2</jats:sub>O-N emissions from European managed peatlands (EU-28) sum up to approximately 145 Gg N year<jats:sup>−1</jats:sup>. From the viewpoint of greenhouse gas emissions, highly degraded agriculturally used peatlands should be rewetted first to optimally reduce cumulative N<jats:sub>2</jats:sub>O-N emissions. Compared to a business-as-usual scenario (no peatland rewetting), rewetting of all drained European peatlands until 2050 using the suggested strategy reduces the cumulative N<jats:sub>2</jats:sub>O-N emissions by 70%. In conclusion, the status of peat degradation should be made a pivotal criterion in prioritising peatlands for restoration.</jats:p>
