Sustainability-ethical testing of methane-reducing technical measures: evaluation of technical measures with regard to the integrated sustainability of livestock farming.
This research makes an inventory of technical measures which are able to reduce the methane emissions of the Dutch livestock production systems (i.e. cattle and pig farming): breeding, composition and quality of feed, use of inhibitors, frequent manure removal from barns, manure additives, manure mixing and aeration, manure cooling, anaerobic digestion, methane oxidation. Through a literature study and expert consultation a qualitative assessment framework has been developed and applied to evaluate different sustainability and ethical aspects of these measures. This has been conducted from the perspective of different stakeholders.
