The Focus Group on reducing emissions from cattle farming explored possibilities for mitigating emissions of ethane and ammonia from cattle – and their cost effectiveness. Its scope included both milk and meat cattle and all types of production intensities but was limited to mitigation measures at animal and animal housing level, including the handling of manure in storage facilities. Before, during and after the two meetings of the 20 expert group, their discussions and group work aimed at: describing the current and up-coming mitigation measures, exploring their cost-effectiveness, identifying success and fail-factors for implementation of emission reducing measures and finding areas where research, development and knowledge-transfer is required. Before the first Focus Group meeting, a starting paper was produced by the coordinating expert and the EIPAGRI service team. As a result of the Focus Group work, seven mini-papers were written by the experts on selected topics. This report summarises the findings of the mini-papers and the discussions during the two meetings of the group of experts, and it includes a description of the mitigation measures for ammonia and methane which were identified. These are divided into two overall groups. The first concerns measures which reduce emissions directly; including feeding, breeding and housing/manure storage measures. The second concerns tools and measures which facilitate emissions reduction, including farm models, precision livestock farming, measuring methods for emissions and synergies between different approaches.
