Different directives of the European Union require operators of waste-to-energy (WTE) plants to report the amount of electricity that is produced from biomass in the waste feed, as well as the amount of fossil CO2 emissions generated by the combustion of fossil waste materials. This paper describes the application of the Balance Method for determining the overall amount of fossil and thus climate relevant CO2 emissions from waste incineration in Austria. The results of 10 Austrian WTE plants (annual waste throughput of around 2,300 kt) demonstrate large seasonal variations in the specific fossil CO2 emissions of the plants as well as large differences between the facilities (annual means range from 32±2 to 51±3 kg CO(2,foss)/GJ heating value). An overall amount of around 924 kt/yr of fossil CO2 for all 10 WTE plants is determined. In comparison biogenic (climate neutral) CO2 emissions amount to 1,187 kt/yr, which corresponds to 56% of the total CO2 emissions from waste incineration. The total energy input via waste feed to the 10 facilities is about 22,500 TJ/yr, of which around 48% can be assigned to biogenic and thus renewable sources.
欧盟的不同指令要求垃圾能源转化（WTE）工厂的运营商报告垃圾进料中生物质产生的电量，以及化石废料燃烧产生的化石二氧化碳排放量。本文描述了平衡法在确定奥地利垃圾焚烧中化石以及与气候相关的二氧化碳排放总量方面的应用。奥地利10家WTE工厂（年垃圾处理量约2300千吨）的结果表明，这些工厂的特定化石二氧化碳排放量存在很大的季节性变化，而且各设施之间也存在很大差异（年平均值范围为32±2至51±3千克CO₂（化石）/吉焦热值）。确定这10家WTE工厂的化石二氧化碳排放总量约为每年924千吨。相比之下，生物源（气候中性）二氧化碳排放量为每年1187千吨，占垃圾焚烧总二氧化碳排放量的56%。这10个设施通过垃圾进料的总能量输入约为每年22500太焦耳，其中约48%可归因于生物源，因此是可再生能源。
