Climate neutrality – a topic that is currently on everyone’s lips – means that we are not negatively contributing to climate change, namely emitting greenhouse gas emissions. According to the Kyoto Protocol greenhouse gases comprise carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), fluorinated greenhouse gases (F-gases) and dust particles. The emission gases in agriculture are N2O and CH4.
Important sources of methane emissions are liquid manure and the storage of manure. Nitrous oxide is mainly produced by spreading nitrogen-containing mineral fertilizers and manure. Transferring broiler manure to a biogas plant, rather than storing it, is one way to reduce these emissions and thus improve the sustainability of keeping and production of broiler chicken.
