This study examines mitigation of GHG emissions from manure storage headspace through oxidisation of CH\n                    <jats:sub>4<\/jats:sub>\n                    emissions at low concentrations, using a thermal catalytic process with and without subsequent CO\n                    <jats:sub>2<\/jats:sub>\n                    capture and storage (CCS). The technology is studied using a combination of process modelling and life cycle assessment at four CH\n                    <jats:sub>4<\/jats:sub>\n                    concentrations: 300, 1000, 3000 and 10,000 ppmv. The primary energy demand and net climate effect were evaluated, reaching a net climate effect of +0.10, -0.77, -0.91 and -0.97\u00a0g CO\n                    <jats:sub>2<\/jats:sub>\n                    -eq emitted\/g CO\n                    <jats:sub>2<\/jats:sub>\n                    mitigated, respectively. The wide range of results is mainly influenced by the process energy demand being strongly correlated to the CH\n                    <jats:sub>4<\/jats:sub>\n                    concentration. The sensitivity analysis shows that a net negative climate effect can also be achieved at 300 ppmv with access to low emission energy sources.
