This paper compares existing livestock emissions and projections on three different spatial levels (global, European, national) and on two sets of system boundaries (inventory data and emission data considering the whole lifecycle). It aims to provide insight in the validity of scenario data of national Austrian livestock emissions. This entails the use of national greenhouse gas emission trends until 2030 – specifically for Austria – as well as EU-based assessments of country emissions up to 2050. In addition, global emission data was extracted from the representative concentration pathways (RCPs) database for the years 2000–2100. Extending national emission projections up to 2100 by combining different datasets connects national emission policies to international strategies. It becomes clear that the goal of keeping average global temperature rise under 2 °C (represented by RCP2.6), even in the medium term to 2030 and only looking at the livestock sector, is much more ambitious than any of the national projections. Furthermore, inventory emission data is set in contrast to emission data considering the whole lifecycle of meat products in Austria, with an overview of assessments from pork and beef production. Emissions reported in inventories represent roughly half of those assigned to the livestock sector in life cycle studies.

本文在三个不同的空间水平（全球，欧洲，国家）和两组系统边界（考虑整个生命周期的清单数据和排放数据）上比较了现有的牲畜排放和预测。它旨在提供有关奥地利国家牲畜排放情景数据有效性的见解。这需要利用直到2030年的国家温室气体排放趋势（尤其是奥地利），以及基于欧盟的2050年前国家排放评估。此外，全球排放数据是从具有代表性的浓度途径（RCP）数据库中提取的。 2000年至2100年。通过组合不同的数据集将国家排放量预测扩展到2100，将国家排放量政策与国际战略联系起来。很明显，即使到2030年中期，仅将畜牧部门的全球平均气温保持在2°C以下（用RCP2.6表示）的目标也比任何国家预测都雄心勃勃。此外，与考虑了奥地利肉类产品整个生命周期的排放数据相比，设置了库存排放数据，并概述了猪肉和牛肉生产的评估。在生命周期研究中，清单报告的排放量约占分配给畜牧部门的排放量的一半。清单排放数据与考虑了奥地利肉类产品整个生命周期的排放数据形成对比，并概述了猪肉和牛肉生产的评估。在生命周期研究中，清单中报告的排放量约占分配给畜牧部门的排放量的一半。清单排放数据与考虑了奥地利肉类产品整个生命周期的排放数据形成对比，并概述了猪肉和牛肉生产的评估。在生命周期研究中，清单报告的排放量约占分配给畜牧部门的排放量的一半。
